To find a hidden spy camera with night vision you should have a look at the working pieces of one of them.  Such cameras come with green or red LEDs which blink in low lights. The LEDs around the camera turn on to compensate for low light for the production of clear images. The step-by-step procedure to find hidden spy camera is:
