The SecurityTronix HD-COAXINATOR™ TVI series ST-HDC2VFTD-MZ 2.8-12mm lens Turret Dome utilizes the same coaxial cable, connectors, and power plugs as a traditional analog camera system. The series is as easy to install as analog but delivers resolution like IP, without video latency or other complexities found when dealing with IP based systems. Integrators can easily upgrade existing systems from analog to HD by simply replacing the old DVR (digital video recorder) and analog cameras with HD-COAXINATOR™ TVI cameras and recorders. Power supply not included.
