Received order of cheap webcams

So I got the three cheap $5 Logitech webcams that I had ordered a week or so ago and attempted to dissect one of them. After not finding a screw hole, I attacked it with some pliers and bent the plastic all off (I later found a screw hole hiding behind a piece of white rubber that allowed it all to easily come apart).

When I got the circuit board off and took the lenses off, I tried to find the IR sensor. It wasn't easily recognizable like the other webcam I had taken apart. I made the mistake of taking off the piece of glass covering the sensor and after doing this to 2 of the cameras, realized that the IR sensor was instead in the lenses housing.


I pried off the lower lenses, and found the IR sensor, a tiny blue square sandwiched between the two lenses. I haven't torn apart the last remaining camera yet. Will leave that to another day. Thank goodness I bought a couple of the cameras and that they were cheap.
