The CMOS video sensor “sees” in a wider spectrum of light than your eyes. At night, this is good because when visible light is missing, the camera still detects infrared.
But in the daytime, the camera needs to have an IR cutout filter between the lens and the sensor otherwise you’ll get odd pink/red images.
I had an Apple iSight FireWire camera (ask your dad) and a common hack twenty years ago was to remove the IR filter so you could have low-level night vision.
So, your problem is the filter is stuck. If you have experience with the v2 cam, you hear the click when the solenoid moves the filter in and out of line-of-sight when switching between day and night (whether you have the IR illuminators activated or not).
It’s a hardware failure. Ask for a replacement or your money back.
