Like all of our hidden camera products this one is sneaky and functional. People are familiar enough with motion detectors to not look twice at one. They may even be aware of some products that have a hidden camera in them. But they may not be prepared for a product with a camera AND a hidden microphone. The 3.6mm pinhole lens provides a nearly 90-degree field of view. The microphone is more than sensitive enough for most rooms. Video output is traditional analog (1Vp-p) composite color. Requires 12VDC (power adapter not included).
