The cheapest camera to support Windows hello is $100+, and I’ve recently seen experts revamping laptop camera accessories to cost as little as $10 (for now).
In fact, the initial cost of as little as $5, I did when the cost was $9, however, businesses have been increasing the price. It already costs $10 at today’s prices, and personally I think you can wait for the price to come down after the heat goes down, or find out if there are any similar ones.
1. Laptop Camera Accessory, Model DELL 0JCXG0
For Alienware 15 17 R3 R4 and DELL 7368 7378 7569 7579 7778 7779
2.MicroUSB Dock and MicroUSB Cable
3. AMS1117-3.3V regulator board, I use a three pin one, it’s smaller.
4. shell, with temporary parking plate processed into, I bought a large size.
5. soldering iron, hot glue gun, thin wires and other tools.
Step 1. The voltage regulator power supply and MicroUSB holder soldered, I am directly cut off the 5V input and 3.3V output pin, the GND pin straightened after plugging into the GND hole of the USB holder. Then connect the VBUS to the 5V input on the regulator board.
Step 2. The pin definitions of the camera board from left to right are in order：
1 5V IR camera power supply
2 GND Infrared camera ground
3 GND Camera Ground
6 3.3V Normal camera power supply
7 I2C DATA data interface (audio)
8 I2C CLK clock interface (audio)
Solder the first 6 pins on the camera board to the stabilizer board and the USB holder with wires in order, the two GNDs can be connected to the GND end made by the USB with one wire. There are some requirements for the solderer here, the pins are relatively small.
Step 3. Test the board to see if it works before installing the case.
First, connect the board to the computer via MicroUSB cable.
Then install the corresponding driver on the computer. The driver needs to download Realtek IR Camera Driver from the DELL website. After installation, you need to restart your computer.
Then find and open Windows Settings – Account – Login Options – Windows hello face. At this time, you can enter the face.
If it works, you can move on to the next step, install the shell.
Step 4. Install the shell
First we need to disassemble the parking plate. The disassembly process is simple. First break the clips on both sides outward to remove the main body. Then pry open a long strip of plastic underneath. Finally vigorously perform a miracle and pry open the main body’s shell.
Then dig the holes in the front against the camera plate, 4 in total. A hole needs to be cut in the back for the MicroUSB port. I chose to put the camera on the right side against the right, and the USB cradle and stabilizer on the left, which is just the right size.
Once the position is set, use the hot glue gun to secure all the boards, you need to hold the boards with your hands and slowly wait for the glue to cool…. Don’t move your hands until the glue cools!
Test the board again to see if it’s working, if it’s OK you can install the housing back on.
The following points were noted during production.
1. When welding, pay attention to the different pins do not short-circuit (except for two GND).
2.Pay attention to the position of the camera when opening the hole, or it will open ugly……..
3. When installing the USB base, it should be perpendicular to the casing, so as to ensure enough space for installation.
4.When fixing with hot melt glue, pay attention to the position of the fixed board before the glue cools down.
With the Windows hello face is still very convenient, no longer have to enter the password.
In addition, the use of temporary parking plate when the shell has an advantage is that you do not want to use when the camera can be turned down, to protect privacy.
