Our line of HD hidden cameras supply a high quality 1080p high definition color video signal. This is done over regular coax wiring. HD hidden cameras are hard-wired only. You must run coax wire between the hidden camera and your DVR. To view or record you will need to use a high definition DVR. The HD image is 4 to 6x better than what you will find on traditional analog cctv cameras. The pinhole camera we use for this line of products is a 2.4 megapixel wide angle color camera. The camera can be changed by the user to CVI, TVI or AHD video format.
