Super Sensitive Hidden Video Camera Detector & Remote Control Tester

Need to locate a hidden video camera that has night vision capability? If so, then this circuit is for you. Also very handy for testing IR remote controls. This circuit uses (2) NPN Darlington transistors in a Darlington configuration along with a proper sized high value biasing resistor from (B-E) to obtain a high level of sensitivity. The use of a visible light filter over the IR LED's can block out most, if not all visible light detection and only allow IR detection to take place.
