Summary: A statement
Foreword: Wangutong
Since the last time I wrote the ASUS AC88U's WebCenter tutorial, I have been quietly following the Internet's articles.
The benefits of ASUS's third-party KOOLSHARE Merlin firmware are self-evident, but there are few Merlin firmwares developed for G6 and R7000 after Netgear. The R8500, which includes Netgear's flagship civilian flagship, does not have any Merlin firmware. news.
Just last year, in Suzhou, based on the KOOLSHARE firmware development team Xiao Bao students, they humbly asked some knowledge, including why NETGEAR R8500 flagship router can not have Merlin firmware? I believe many people would like to ask this question, IPTABLES in the R8500's firmware is very special, so it can not be positioned to some functions, integration and modification is very difficult, so Xiaobao students talked about a plug-in firmware concept: million Solid! Compiling a plug-in can be plugged outside of any relevant firmware to achieve the functions we want. This is the basic concept of WanGongTong. Therefore, we can't wait to join the R8500's internal testing team. In fact, I'm just honest about it. When I didn't have R8500 in the hand, I also used three days to fish for two days. I had to feel so embarrassed that I hadn't been soaked for six months. I finally changed the three editions in June this year and the R8500 KOOLSHARE firmware finally The development has taken shape, and for a non-profit pure technology R&D team, this is already remarkable.
In fact, we are always being bombarded by the parameters of the propaganda of various network product manufacturers, resulting in impulsive consumption to buy some high-end network products. To tell the truth, based on my experience, I feel that I’m willing to pay 3,000 yuan to buy a high-end router player. Buying a GTX1080 is not blinking. This is not just a concept that just needs to be consumed, but do you really need high-end network equipment? Do you really use high-end network equipment? Do you really choose the right high-end network equipment? With these three questions, I wrote this article, not only about routers but also NAS, TV, network cards, video surveillance, and thoroughly brought you into my network center. I hope that I can embark on a journey to bring the truth to the forefront. Multi-master communication and guidance.

When I bought a house, I bought a house for my parents downstairs. It was right below my room. I lived in 506, my mother lived in 406, and all the units were the same, so I just had 2 squares. It is mainly because old people bring children, we take care of the elderly, and it is very convenient for us to cook meals. Buying 2 rooms can also avoid the contradiction between mother-in-law and mother-in-law. . . . . .
Huawei HG8240 fiber cat home, LAN1 R8500 routing dial, two NAS: HP GEN8, iron Weimar F2 220 are on the fifth floor
Huawei HG8240 fiber cat home, LAN4 R7800 routing dial-up
The IPTV Tianyi Package of China Telecom in Anhui Province can be used for double-dial and non-recurring charging (uncertain in other regions). Therefore, it is only natural that a single broadband can be dialed independently by two routers through the Huawei HG8240 optical cat. The actual principle and single router are double. Dial the same, the two LAN corresponding to 2 different MAC numbers, I just dial two routers dial only, but the bandwidth will change, 100M double dial after the two lines are only about 70M.
The second chapter of the backbone of the network center - router
Routers In fact, many routers like to buy high-end directly, but in fact they do not understand why you buy an Asus AC5300 or NETGEAR R8500. What are more factors? In fact, I did some research in my group: Why buy a high-end router? The excerpts from the answers of high-end group friends:
50 Yangzhou - Guanghui 23:04:00
There aren’t many people who buy 600 routes or more, and even less than 1,000 are basically feverish. There is no reason to have a fever.
10 Weifang-ASUS AC88U♣ 22:49:14
Asus NETGEAR is a symbol of high-end, just like you have money to buy Rolls-Royce. I think the other hardware peripherals that can buy 1k+ routers are not bad either. In fact, the most critical is that the network speed is very fast, and ADSL will not be used to buy a high-end routing.
100 pieces of Nanjing + wind disease 22:48:48
There are also people who buy high-end products. I don't buy them and I can't justify them. You all use iPhones. I will buy them, too. Anyway, for me, routing is more expensive and I can afford to see if I am willing to buy it. I believe everyone is the same without having to install it.
100 Blocks of Shanghai - God 22:45:37
Mostly for the $$ and APP plug-ins, in addition, Merlin's UI interface is also comfortable and beautiful.
50 Beijing - noName 22:41:33
High-end routers have a relatively large capacity. There are still demands for the rented houses in my home. Multiple stations could not be covered before, and now an AC5300 is ready. Another way to play routing and play wenwan, you see who play dozens of wenwan play it? Time and effort are all costs. Since you decide to play, why not find a flagship to play, use experience can be widely disseminated, 100 yuan routing you are playing out of flowers, sales are not good, then Jingdong about your energy time and The sense of recognition gained was all cleared.
The world of Tyrant may not understand me, but I can at least look for answers with some questions.
The NETGEAR flagship R8500 I purchased was purely for testing the firmware. After all, it was the first AC5300 router.
In fact, there are often students like to say that tri-band router is useless, dual-band is enough, I agree with the concept, but the three-band NETGEAR R8500 really is a bit of development skills, this first bag I put later .
The concept of AC5300 does not know how many people tempted to contribute to the bills and evaluation in Jingdong. Actually, people who really understand the concept of AC5300 are still few. The AC5300 is only a concept. The sum of the maximum link speeds of the three frequency bands of the router is equal to 5.3 Gbps. Therefore, regardless of the ASUS AC5300 or the NETGEAR R8500, the actual AC5300 is: 2.4G Maximum 1 Gbps + 5 G1 Maximum 2.167 Gbps + 5 G2 Maximum 2.167 Gbps = maximum tri-band bandwidth sum 5.34 Gbps = AC5300. However, 5G can reach 2.167Gbps, which has surpassed the speed of Gigabit Ethernet 1Gbps by more than two times. It may be that many people may go for the concept that wireless may really surpass the wired one, but can wireless really outperform the wired one? Actually not, the second baggage is left behind.
Out of the box, in fact, we have opened many times, and I will open a few casually.
The design style of American goods always lingers between rules and ruthlessness, but it cannot be said that it lacks imagination. It can only be said that in the category of mass production standard design in the era of big industry, net parts have always been a model of law-abiding, neither. Exaggerated, not old.
Family portrait
Although the design of the R8500 is a standard rectangle, the S-shaped wave of the upper design is breaking the convention, but regardless of how the design of the mesh will always allow you to identify it as a router, rather than as an art like the Eight Immortals table. Products, of which 2.4G and 5G1 use external four antennas, 5G1 uses four built-in antennas, so the surface looks only four antennas, in fact, eight antennas.
The positive and negative ribbed heat dissipation design is indeed good for heat dissipation, but the ash problem does not know whether it has been considered before?
Americans always like to design LOGO in a seemingly inconspicuous but actually prominent position. APPLE is such that NETGEAR is also true.
The front panel is designed with three switches of LED/WPS/WIFI, which can easily switch the function, and send faint blue light when the power is on.
The indicator area is designed on the left side of the router. Noteworthy lights 1-6 indicate the connection status of LAN 1-6. The white light indicates Gigabit and the red light indicates Fast.
The functional interface of the router is designed on the right side. And there is a cover design.
Built a USB2.0 a USB3.0 interface, to be honest, BCM47094 USB3.0 speed do not have great hope, can do stable 70MB/S is very good.
The IO interface area on the back has been designed with a 1WAN 6LAN design.
Among them, LAN1-2 supports link aggregation.
There was a lot of dismantling on the Internet, so I hand-painted the R8500 basic architecture diagram for friends who are interested in understanding the structure. ARM A9 dual-core 1.4G SOC module, two Gigabit switch modules, three dual-band wireless modules, 512MB of memory, 128MB of flash memory, basically constitute the hardware body of the R8500.
For the first time, the active antenna design was used in the R8500 design, and for the first time the 2.4G and 5G1 were combined on a group of antennas, which were distinguished by the positive and negative polarities of the active antenna.
The 5G2 is still a very traditional built-in 4X4 panel antenna similar to the R6300 V2 design.
BCM47094 is actually Broadcom's BCM4709C0 SOC chip. Basically, no one on the network has drawn the architecture diagram of BCM47094. So I simplified some interfaces and simplified the architecture and drawing out according to the actual interface and content of R8500.
Accurately speaking, the BCM47094 is called a CPU. I personally feel a bit Chinese. In fact, this is an integrated chip solution, including the ARM A9 dual-core CPU, Gigabit switching chips, and dedicated hardware accelerators. It is not traditional meaning. The CPU mentioned above is so simple. In the present situation, it should be one of the top solutions in router products.
The graphic attributes are as follows:
1. Cortex-A9 CPU with built-in ARM, dual-core 1.4GHz frequency, 256KB L2 cache, 32KB 4-way association instruction cache, and 32KB 4-way linked data cache.
2, built-in Gigabit switch supports five full Gigabit, backplane bandwidth 1.8Gbps
3, built-in hardware interaction and file transfer accelerator
4ã€Extend three PCIE2.0X1 buses, one of which has been linked to USB3.0, and the other two can expand the WIFI chip
5, built-in DDR3 memory controller, maximum support 512MB
6, can be external flash memory chip
7, built-in USB2.0 standard interface
8, built-in RGMII interface, bandwidth 1Gbps, can expand the second-tier Gigabit Ethernet switch chip (R8500 is BCM53125)
In terms of the function of the router itself, data operations are relatively simple operations, and the CPU requirements are not high. Usually, data processing (NAT network address translation) also has dedicated hardware acceleration processors (coprocessors) for processing. , so the CPU requirements are even lower. For the router, the core function is data forwarding. For example, if you give you a Gigabit fiber optic line, you can use a router with tens of blocks and you may not be able to reach 100M download speeds. This will give you a hardware-accelerated NAT function. For the router, it is easy to run to Gigabit. Since the CPU is basically not used, the CPU usage may not even reach 10%. Therefore, it is not reasonable to use the CPU alone to measure whether the router is strong.
The R8500 uses three 5G WIFI chips, the BCM4366, also from Broadcom, one of which is responsible for the 2.4G band and two of which are responsible for the 5G band. Because DATESHEET of BCM4366 basically does not flow out, so I painted the picture myself.
(1) Built-in single-core ARM Cortex-A7 800MHZ processor as a co-processor can share the load of the BCM47094 in the wireless transmission process.
(2) 4x4:4 MU-MIMO architecture supporting 802.11ABGN+AC.
(3) The link interface is PCIE2.0, and BCM47094 links BCM4366 through PCIE2.0.
(4) Beamforing (waveforming beam) technology that supports versatility and 802.11AC.
(5) Support NitroQAM modulation and demodulation technology, namely 1024-QAM.
The point about modulation and demodulation technology
Question 1: Passer A: If I bought the R8500, how fast can my home 5G network reach?
If this question is answered to the manufacturer, he may tell you that your home can reach AC5300, which is 5.3Gbps. The actual situation is not the case, it all depends on your wireless network card, at present the strongest ASUS PCE-AC88 NIC up to 5G can reach 2.1Gbps which is currently the highest.
Second problem, passerby A: If I bought a PCE-AC68 network card and PCE-AC88 network card, with R8500, 5G maximum speed can reach?
The PCE-AC68 has only 1.3Gbps and the PCE-AC88 can reach 2.1Gbps.
Question 3, passerby B: My home is INTEL AC7260, will I buy this R8500, 5G can reach what speed?
Only 866Mbps.
In fact, regardless of 802.11N or AC network, we need modulation and demodulation frequency in order to achieve the corresponding speed. This mode of modulation and demodulation we are currently talking about more is a string of digital +QAM, QAM full name is Quadrature Amplitude Modulation, That is, quadrature amplitude modulation is a modulation method that performs amplitude modulation on two orthogonal carriers, and has the advantages of being able to fully utilize bandwidth and strong anti-noise ability. There are many different modes of QAM, the most basic modulation mode of 11N is 64-QAM, and the basic modulation mode of 11AC is 256-QAM. Later, Broadcom adopted a new 1024-QAM modulation and demodulation method named NitroQAM. The single antenna supports 80Mhz frequency of 802.11AC. The wireless device using 1024-QAM modulation mode can achieve a link speed of 542Mbps. Using a BCM4366 network card, this type of 4X4 ​​MU- MIMO can use 1024-QAM modulation and demodulation under 802.11AC, which can achieve four times the effect, that is, maximum 2168Mbps.
NETGEAR's V1.0.2.64 is the latest R8500 firmware. In Basic-Wireless, we can see that 2.4G is preset to 1000Mbps, and 5G1 and 5G2 have preset 2165Mbps, which adds up to 5300Mbps link speed. , exactly corresponds to AC5300. If you want to test, the most critical is the 5165 speed test under the 2165Mbps, but to test, you first need to have a BCM4366 chip wireless network card, there is no choice but ASUS PCE-AC88, the only one.
PCE-AC88 nominal 2.4G up to 1000Mbps, 5G up to 2100Mbps
4X4 MU-MIMO antenna design
PCIE3.0X1 interface design
First find a PCIE3.0X1 slot plugged network card
Connect the IPEX antenna
The antenna base comes with magnetic force and I directly fix it behind the chassis.
Test the entire machine at a glance.
With Advantech's mobile workstation AMIS60, we can easily turn a desktop into a mobile workstation mobile test.
The reason is that the AMIS60 comes with the IP420 Lithium battery to ensure that the desktop is constantly running.
Many people say that the R8500 is too slow and not fast, mainly because of this magical hook. It is not marked. The default is to not play. To test the maximum speed, check the SMART CONNECT. Nets seem to have made a mechanism. If not ticked, the default 5G band is only 256QAM modem mode. After ticking, the speed is up to 1024QAM and the speed difference is too large. After the check, the original 5G1 and 5G2 wireless SSIDs are combined into one SSID.
SMART CONNECT is actually an intelligent network selection. Although there is only one 5G SSID, the internal wireless device that is near to the router is preferentially allocated to 5G2 by default. The built-in 4X4 antenna has the best in the case of near-field small-range coverage. Connection quality; The wireless devices that are far from the router and have wall-penetration are preferentially allocated to 5G1. The external 4X4 active antenna has inherent advantages for wall penetration and long-distance. This makes it flexible to use all the 2 5G bands. Therefore, some students said that 5G only needs one frequency band, but it is also true, but netware is a flexible allocation of two 5Gs. The advantage of doing so is that the quality of the client's links can be managed more scientifically.
The PCE-AC88 network card did achieve a transmission speed of 2.1 Gbps when the tester was three meters away from the R8500.
The test system is a top-level version of the HP MIRCOSERVER GEN8, which is equipped with an E3 1230 V2 CPU and Elpida DDR3-1866 ECC 8GBX2 memory, dual 2T hard drives, and dual 480G SSDs.
I connect LAN1 and LAN2 of HP MIRCOSERVER GEN8 to LAN1 and LAN2 of R8500 and enable LACP link aggregation
Through the ILO network port of HP MIRCOSERVER GEN8 to enter the remote management interface to establish dynamic LACP link aggregation for LAN1 and LAN2. At this time, the bandwidth of dual-NIC aggregation is 2Gbps.
I chose to wirelessly download more than 100GB of video files from the SSD of the HP MIRCOSERVER GEN8 to the tester. From beginning to end, the download bandwidth of the PCE-AC88 did not exceed 1Gbps, and the download speed was between 106~124MB/s. stable. Obviously, even if the WIFI chip is linked by 2.1Gbps bandwidth, and the bandwidth link between the WIFI chip and the CPU is PCIE2.0X1, it is limited to the 1Gbps bottleneck of the router's CPU to the switch, so we still don't see the wireless breakthrough. Gigabit, it's a pity that we can only expect the next-generation routing to use 2.5G network ports to solve this problem.
By the way, more than one machine downloads the files in GEN8 at the same time, forcing the highest bandwidth of the link aggregation. At this time we see 1.8Gbps, and for the R8500's own LAN1~2, it can achieve 1.8G link aggregation. The bandwidth is already very good. At the same time, it also proves that there is no problem in the bandwidth of our link aggregation system.
Therefore, 5G link bandwidth even if both routers and wireless network cards use the supporting equipment of 2.1Gbps BCM4366 chip, the link speed also reaches 2.1Gbps. At this time, the theoretical transmission speed should be around 270MB/S, but it is limited to the built-in R8500. The link bandwidth between the Gigabit switch and the CPU is 1 Gbps, so even if the speed between WIFI chip and CPU can reach 10 Gbps, the transmission speed cannot exceed the theoretical transmission speed of 1 Gbps Gigabit network at 125 MB/S.
Mobile testing
The test site is ABCD four points
A: 3 meters away from R8500, no shelter
B: 5 meters away from R8500, no shelter
C: 5 meters away from R8500, a wall blocking
D: At a distance of 7 meters from R8500, a wall is blocked
A point 2.1Gbps
B point 1.9Gbps
C point 1.5Gbps
D point 1.3Gbps
In fact, whether it is 2.1G or 1.3G is not much difference here, the same download upload can not break through the 1Gbps bottleneck limit, that is, can not break 125MB/S, stable transmission speed is maintained at about 100MB/S. Although we can't say that wireless is better than wired, it is almost the same. This is true whether the ASUS AC5300 or the NETGEAR R8500 is the same, as long as the BCM47094+BCM4366 solution is adopted.
Chapter 3 R8500 KOOLSHARE Firmware
R8500 KOOLSHARE firmware is currently in beta
1, increase the support of $$.
2, increase DDNS peanut shell support.
Specific download address:
Upgrading the firmware is also very simple:
After downloading, upload it directly in the router upgrade section.
Section 1 Peanut Shell Intranet Mapping
The following will talk about using R8500 KOOLSHARE firmware to establish a simple private cloud through the peanut shell DDNS.
Say peanut shells have to talk about his intranet mapping service. Most of our broadband users do not have independent public network IP, so they cannot be accessed through the public network. Peanut shells will use their intranet DDNS servers and DNS servers. Our intranet IP is mapped to the public network. The domain name bound to the peanut shell can be resolved by the public network so that our NAS data can be accessed by the public network. This is the prototype of a private cloud.
To establish a private cloud through the Peanut shell's intranet mapping, first you need to have a peanut stick or a NAS that supports Peanut Shell Intranet mapping. Secondly, your router needs to support the intranet mapping and DDNS of the peanut shell. For the convenience of testing, I directly took a fermware F2 220 NAS with built-in peanut shell inner screen version SN to test.
Packaging
Product Identification
Family portrait
In fact, I have the top version of the HP MIRCOSERVER GEN8, the E3 1230 V2 CPU and Elpida DDR3-1866 ECC 8GBX2 memory, dual 2T hard drive, dual 480G SSD, this configuration toss down also spent eight thousand, but Hang on the pit in this top, honest and practical for a year down, I feel not tossing tossing this configuration with the top, so Black Apple, EXSI and Black Group Hui kept tossing, and even for a while I think GEN8 should With a knife card when the HTPC use only fun, a tossing can not be honest when the NAS used, so I decided to buy a cheap NAS back to replace the GEN8 position, so you can concentrate on gen8, so F2 220 Into my house, F2 220 CPU is a standard X86 Intel 22NM dual-core Celeron J1800, clocked at 2.4GHz support Turbo to 2.51GHz, built-in 2GB of DDR3 memory, and built-in notebook memory slots can expand memory, 3.5-inch dual-disc position, maximum support 8T dual-disk is 16T capacity, built-in Gigabit Ethernet port, one USB3.0 interface, one USB2.0 interface. At that time, I was excited to buy it for the X86 architecture CPU and memory can be expanded, wanted to toss the black group Hui or add APP in the background, busy and no time to toss it also used.
The switch is set on the front panel, and the LEDs for the hard disk and network power are also built into the front panel.
USB3.0 and 2.0 interfaces, RJ45 network ports, and power interfaces are all located on the back.
Double disk design
I used two 8TB Seagate NAS hard drives to assemble him.
The scheme of the peanut shell private cloud is as above.
First of all, the F2 220 has a built-in Peanut Shell Screen Edition, which is similar to a built-in peanut bar.
When logging in to the management, you can see that the SN is actually the authorized device code of the peanut shell. The default password is ADMIN.
After logging in, you can bind this device to your registration ID
Register a shell domain name in the list of domain names on the left. My registration is free.
Click on the domain you just registered in the intranet penetration on the left and select Edit to bind the NAS device to this domain name
In this way, the intranet access address of the NAS: 192.168.1.3:8181 is bound to the domain name accessed by the external network. But light is not enough
We also need to find the port mapping and port forwarding in the settings of the R8500 router and map out 192.168.1.3:8181.
Finally, find the dynamic DNS in the KOOLSHARE firmware, find the DDNS of KOOLSHARE customized peanut shell, fill in your registered peanut shell domain name, and connect the binding.
At this time, enter the peanut shell management page to find self-diagnosis. The test result indicates that the server has been successfully linked to the peanut shell. The domain name can be resolved by the public network.
At this time, find the browser, enter our domain name, and you can access your home NAS from anywhere.
When a friend asks you for a file, you can use the peanut shell's domain name to remotely log in to the NAS management page and share the required files with your friends as a link.
Because of the free version of Peanut Shell, I did a download speed test, which is about 120KB/s or so. The traffic is also limited to 1G traffic in a month. If you want faster speed and more traffic, then you have to Paid for it.
Here to say aside, for the NAS manufacturers I think we have a lot of rights to do things that can be done, I never like to do it to accept the consumer, on this F2 220 I have many complaints on the site, for We pay to buy peanut shell traffic, since you bought a peanut shell SN authorized to buy more account traffic to the user? In addition, since the localization of NAS is not to develop Baidu cloud synchronization APP? After continuous struggle with customer service, it may be that everyone will see results in the APP in August.
The second quarter mesh cloud READYCLOUD
I would like to continue to say that under the NETGEAR high-end router comes with the cloud service READYCLOUD
READYCLOUD build a framework
The test equipment I used was a USB flash drive with HYPER X SAVAGE 128GB USB3.1, which read 350MB/S and write 250MB/S.
This high-end disk test was chosen only to prevent U disk read and write speeds from being the bottleneck of testing.
Group leader PS2251's master control Toshiba TH58NVG7DDJA00 MLC particles, U disk inside, this should be considered high-end goods, of course, and Wang Sicong that KST 1T U disk to sell 9999 can not be compared.
Sustained reading and writing also do meet the standard.
Insert the Kingston Hyper X USB3.1 128GB USB stick into the R8500's USB3.0 port, open the router management page, find the READYCLOUD in the easy share, and click.
Then register your READYCLOUD account on this page and click Register.
Click OK.
Then find the storage component in the normal USB function, you can see that READYCLOUD has been successfully bound to your registered account.
Now that the Widget Cloud has been successfully established, you can log in to your account by typing: readycloud.netgear.com in any browser.
The contents of the Kingston HYPER X USB3.1 128GB U disk are all displayed at this time
In addition to READYCLOUD upload and download, one of the two most direct features is to create a WEB link.
The method of sharing with the previous F2 220 NAS is very similar. Share files directly by link so that you can send the link directly to your friends and let them download the files you provide.
I created a WEB link to download and read it, because it is a single-threaded download, the actual speed is only between 60-100KB/S.
Another major feature is EMAIL push, send file links via email
After sending, the mailbox immediately received a READYCLOUD link email, click to download the file.
After talking about the performance of the external network of the R8500 USB device, let's talk about intranet sharing. The external network cloud of the USB device is called READYCLOUD, and the internal network share is called READYSHARE. In fact, the DLNA and SAMBA protocols are enabled by default.
The HYPER X SAVAGE USB 3.1 128GB USB flash drive can be easily found on the TV through the DLNA protocol, which is defined as the READYSHARE folder because it is connected to the R8500.
One of the 4K test strips was played over the air. The whole process was smooth and uninterrupted. By the way, the micro whale 43 4K had a 866 Mbps wireless network card. The theoretical transmission of 108 MB/s or so may not be the bottleneck of the test, so the USB read/write performance of the R8500 in the middle part can also satisfy the bandwidth of 4K video playback.
Section III
I do not know if you have noticed that there is a $$ option at the bottom of the KOOLSAHRE firmware
After we enter the account. . . . . .
You know it. . . . . .
Brush PS4 Hong Kong service will never enter or be stuck.
Chapter IV Network Cloud Monitoring
Let me talk about my monitoring equipment ARLO
This kind of packaging is very difficult to restore once it is removed
Inside the box is a base station and power adapter, 8 Panasonic CR123A batteries, a network cable, four mounting bases and attachment screws
The camera adopts IP65 waterproof and dustproof design
This camera is a full wireless design, using 2.4G WIFI and the base station for interconnection. The result of my test is that the camera is about 15 meters away from the base station. There is no problem with a link through the wall. The house is so big that it has never been tried.
Panasonic CR123A battery is too expensive, and only send a set, and can not be recharged, so I could not bear to use, and bought eight Nike CR123A 400MA rechargeable battery to use. If this thing can not withstand the Panasonic original battery can not withstand a few months, the official said that the top half of the year, but I use Naijie CR123A 400MA can withstand more than a month.
The battery is also very simple to install, the figure is a rubber stopper in the red box, after the split is the MICRO USB interface, in the case of the camera without a battery, use a MICRO USB to connect the computer USB or adapter can be used to provide power for the ARLO, but can not be charged please note.
The fixed base is fixed with expansion screw hooks. I don't use this directly. Where I want to place it.
Due to the magnetic force of the camera base, it can be firmly attached to the base.
The base station is actually a dedicated 11N AP. The SOC of the base station is Broadcom's BCM4334, supports IEEE 802.11n, supports 2.4GHz/5GHz dual-band, 2.4g 150Mbps, and 5g 300Mbps. Here, only 2.4G transmission is used because of 2.4G transmission. long distance.
Configure a dual USB port and a LAN port, and the LAN access router's LAN can be networked.
The side SYNC sync button is pressed in the power-on network, then hold down the SYNC button on the camera until the blue flash on the camera flashes and the pairing is successful.
To be honest, the price of this thing is not cheap at all. It's just like wireless and transmission distance. It doesn't need plug-in wires, it has high degree of freedom, its definition is about HD 720P, and it has built-in Amazon cloud service.
The biggest impetus for me to purchase this stuff is Jingdong's evaluation, which is really overbearing.
Web pages can log in directly to the cloud
Just when we entered the cloud today, one camera had run out of electricity, from the time it took to use the battery of the Nike CR123A 400MA for a total of 35 days.
This thing uses a fisheye lens because it is a wide-angle lens, so it is a bit distorted at close range. This thing is not decent in addition to this brand. Because many places can't be wired and powered after the house is remodeled, the battery has been charged for a long time and the whole wireless network has been particularly convenient.
Amazon Cloud Provides Video Rollback of 7 Days of 1G Traffic
APP-side access is similar to the PC version and has the same basic functions.
For our three-day and one-night shift work, we can get some information about the child’s home situation through video playback. Today, my wife told me to hang a camera at the bathroom door, and the kindergarten teacher reflected that the child had been playing urine for only one day. Pai suggested to go to the hospital to see, so after the wife decided to sternly educate the baby, monitor the baby several times a day in the bathroom at home. . . . .
Summary: A statement
About my own choice of routers:
First of all, look at your own network client wireless environment. You can view the network topology of wireless and wired devices through the NETGEAR client. I have 11 network devices, 7 wireless devices, 3 wired devices, and ARLO needs a network. In fact, the F2 220 requires a network port. The HP GEN8 requires three network ports. It always requires five LAN ports.
Only one desktop has a wireless link speed of 1.73G, but the actual wireless-to-NAS transfer rate is limited to 1 Gbps or 125 MB/s.
Micro whale 4K TV link speed 866M
PS4 also only 144M
X230 notebook comes with N6205 network card is only 300M.
In fact, my actual situation is completely unnecessary wireless equipment is too strong, a R7000 or AC68U enough, but I need five LAN is a flawed, most routers are generally 4LAN1WAN, so whether or not the R8500 AC88U, or a R7000 or AC68U plus a switch. In addition, if there is a demand for $$, try to select the ASUS and Netware models with the $ firmware.
About NAS: HP GEN8 I have been playing for more than a year now. I feel that NAS is trying not to choose to toss products that are too energy-consuming. Otherwise, you can't use them safely. After three days and two toss, the finished professional NAS can be considered. Try not to choose ARM. The product, it is possible to choose the X86 architecture CPU products, vitality will be a lot longer.
Regarding link aggregation: home routers, whether it is a router or a NAS, link aggregation can only reflect the usefulness when multiple devices access a storage device at the same time. Most of the time of home use is wrong, in fact, personal opinion is completely Can not be considered.
About Offline Thunder: Since February 6, 2016, XWARE's authorization has been terminated. Most NAS manufacturers and router manufacturers have been asked by Thunder to stop download support for remote offline Thunder. With Thunder's blockade of island acrobatics reaching an unprecedented peak, the significance of this thing is gradually diminishing. If you have to tangled up with the router or NAS to support the Thunder issue, you might as well buy a Thunder directly to download the treasure behind the router. .
On the Internet 4K TV: The richness of resources is an important aspect to consider. The other is to choose the IPS panel products as much as possible. The built-in wireless network card tries to select the 5G standard as possible, otherwise the 4K video in the DLNA on-demand NAS will be very difficult.
Regarding monitoring: There is not a single domestic product that can achieve ARRO's level of wireless self-contained batteries, so the monopoly of this technology is really summed up in one sentence: Because it is expensive.
