Get the surveillance power of full 1080p high definition digital images without sacrificing features or convenient setup. The QH8003B is a1080p high definition digital camera that delivers an effective resolution over 40% greater than the best conventional, analog security cameras. The camera connects directly and securely to the DVR with a single cable rather than the cumbersome double-wire solution required by comparable models. And, because the camera has a direct connection, there's no need to worry about overloading the bandwidth on your network. The included professional grade, shielded Siamese RG59 cables deliver power to the cameras and high definition video back to the DVR, ensuring maximum video quality free of electronic interference. Your camera will be delivering the highest quality video from the moment you plug them in. Advanced IR cut-filters plus on-screen display (OSD) functionality lets you customize each camera's video signal to give the best results based on each camera's location and situation day or night. The camera will automatically switch from full color to infrared night vision and the 30 IR LEDs will invisibly illuminate up to 50 feet away, but they will take advantage of any environmental lighting to provide a view of the area up to 120 feet distant. If you already have an existing system using RG59 cables, you won't have to remove your current wiring - just connect your new cameras and DVR and start enjoying the difference that full HD digital makes.
