NETGEAR ARLO teardown IP65 dust-proof secret
NETGEAR ARLO has introduced a smart HD dual camera home surveillance system with IP65 protection. There is no need for external power supply, no wiring, and we will unlock the secrets for you today.
I have always had to dismantle the internal work materials so this time is no exception.
The dismantling of the base station is relatively simple. Remove the base by removing the two screws at the bottom, and then insert the buckle around the top of the paddle.
If you continue to move out of the antenna, you need to pay attention to the use of snap-fitting. Therefore, you need to open your hand and open it again, otherwise it is easy to cut off the snap.
It is relatively simple to remove the motherboard, and you can extract it from the right side. Motherboards are covered with metal covers to prevent signal interference and increase stability.
Open the metal cover must use hot air **, for the novice is more risky, easy to blow the chip, so this step is not recommended for everyone to try.
The master used Broadcom's BCM5358BOKFBG to support 2.4G 5G dual-band.
2.4G part of the circuit uses a 2X2 design, each circuit is equipped with a SIGE 2528 power amplifier, increasing the strength of the 2.4G signal.
Winbond's 128MB SDROM is only used to transfer NETGEAR ARLO data with such a large amount of memory. This is really overkill.
The appearance of the motherboard, the left side of the air welding should be 5G part. This is not difficult to understand, NETGEAR ARLO compressed data traffic is not large, so more than 5G is the 2.4G wall penetration capability to ensure that two NETGEAR ARLO cameras can send and receive data.
On the back is a Winbond 128MB flash memory.
To the family portrait of a base station, it is not difficult to find this base station. Basically, it is a reduced version of the 5G circuit and 4 LAN interfaces of the NETGEAR V3400 router. This means that routers using netware can also implement the functions of the base station. This is consistent with the function of the base station achieved by upgrading the firmware through the R7000 in the manual. If a user with a NETGEAR R7000 or higher-end NETWORK router at home can directly purchase two NETGEAR ARLO cameras and routers, it is more economical to use. Of course, the base station is more stable. After all, it is only responsible for the encryption and transmission and reception of NETGEAR ARLO data. With a 128MB of memory and 128MB of flash memory, special plane, do not run other data.
After dismantling the base station, remove the NETGEAR ARLO camera, remove the battery before disassembling, and then withdraw the bottom screw. At this time, it was found that a Micro USB port was hidden at the bottom and the white lid was removed.
Specifically studied this interface, insert the computer's USB interface can give NETGEAR ARLO camera can work, and the computer has prompted to find new hardware. It is speculated that this interface can not only provide external 5V power supply, but also realize data transmission.
The first study of how to disassemble for more than half an hour was due to the fact that the NETGEAR ARLO camera was designed with IP65 protection. This is an international standard, 6 means that dust is completely prevented from entering, 5 means that high pressure injection has no effect, and therefore the structure is very tight. 0.02 feeler gauge can not be inserted, which is why I have not found how to tear down the root cause.
Finally, according to his many years of disassembled experience, the judge should start from the front panel of the camera. In order not to affect the camera, cover it with a corner coin and heat the surroundings. Then use the blade to open the panel and you can see that the back is really gluey.
The screws under the front cover are really enough, it can be said to be fixed to every corner. Remove the front panel by removing 7 screws and insert the paddle through the notch of the front panel to open the left side panel.
There are still 2 screws on the right side. Withdraw the screw and use the lever to open the right side plate.
At this time, it can be clearly seen that the camera's internal components are wrapped in a transparent cover, with a black plastic sealing ring at the joint of the second half, and reinforced with screws, which is NETGEAR ARLO camera can completely prevent dust and IP65 pole waterproof The root cause.
The SYNC button at the top is fixed with 2 screws. After removal, you can see the waterproof isolation pad underneath.
The SYNC key is designed with a waterproof isolation pad, a fixed cover and reinforced with screws, which serves the purpose of preventing dust and water.
Continue to remove and remove the 4 screws on the edge. Further dismantling the need to leave the data cable, and then exit the back of the two screws can pull out the internal motherboard part.
It can be seen that the NETGEAR ARLO camera supports the suction base because a strong magnet was designed behind it. Continue to separate the cables of the Micro USB interface.
In order to save space, the main circuit board adopts a double-layer design and exits the fixed 4 black screws. Do not dial first. There is a power supply interface between the main circuit board and the power supply circuit board. Separation is the best. Then withdraw the four screws of the power supply circuit board and completely separate them.
Two WIFI antennas can be seen on the motherboard. The WIFI chip is shielded with a metal shield.
Front can see the Texas Instruments M430 microprocessor, Winbond's 4M flash memory, wifi part uses Broadcom's BCM4334 chip, this chip belongs to IEEE 802.11n products, supports 2.4GHz/5GHz dual-band, WIFI uses 2X2 design, design There is SKY11 65534 wireless power amplifier.
The back is mainly OmuiVision's OV00788 image processing chip and Winbond's 128MB SDROM.
Continue to remove the circuit board from the camera. After separating the cables, remove the 6 fixing screws, and the middle two of them are used to fix the lens.
This also uses a two-layer daughter board design. The board below integrates sensors such as infrared generation and motion detection.
The coating on the front glass lens of the camera increases the light transmittance, similar to the UV mirror. The infrared sensor used for motion detection is also designed with a protective cover, which is also provided with a waterproof insulation pad.
A total of 12 infrared emitters were designed for night photography. Compared to a single large power, this method has more uniform light and better reliability. Similar to the practice of multiple LEDs integrated in a single high power. The single light is concentrated, and the middle brightness is high in the visible area. However, although the brightness in the middle is not as high as the power, the light is uniform and the viewing range is wide. At the same time, it is also possible to avoid working after a single problem, and multiple cannot be output at the same time. The problem is therefore better in terms of reliability.
The light sensor is used to assist the micro-processing to determine that infrared night vision is not needed, and the infrared sensor is used for motion detection to determine whether the camera needs to be recorded.
The difference lies in the integration of the small camera, NETGEAR ARLO design has a complete lens module and a large area of ​​the COM module, is conducive to normal conditions of poor light.
The lens part has a red coating to enhance night vision.
CMOS uses the VOV9712 low-power image pick-up.
The NETGEAR ARLO camera family portrait, because the two cameras are exactly the same, so only one by one to see what happens.
This is based on the dismantling of their own analysis of the architecture diagram. After the arming, the M430 microprocessor judges that the infrared sensor works during the arming time. When monitoring the motion, it reads the data of the light sensor to determine whether it needs to turn on the infrared light, and then interacts with the OV00788. The OV9712 starts to work and acquires the video screen, which is processed by OV00788. Compressed and transmitted to the base station via WIFI.
