They alsoneed some used film negatives, some high-intensity infrared LEDs that device from any electronics store for less than a dollar a power for the LED lights you need for less than ten dollars, a few boxes, polarity wires can get can get an electronic bread, and tools such as a welder.
First you need to unscrew the camera through its plastic case open. Then try the webcam, removed from the optical media. On some cameras, the assembly is screwed,while on other cameras, it's just kind of shots.
Once you have taken from the lens, you should see a small square glass to the floor.
