Start at one point of the room and slowly work your way around. Try to be within 10-5ft of the objects you are scanning. If you scan with the infrared filter you will detect the camera by seeing a red reflective spot. This will look similar to a mirror reflection. The lens acts like a mirror when the laser LEDs hit them showing where the camera is disguised.
