The SecurityTronix ST-HDC2VFB-MZ sends HD video over coaxial cable making this camera a cost effective high-definition surveillance solution for any budget. The HD-COAXINATOR™ TVI series utilizes the same coaxial cable, connectors, and power plugs as a traditional analog camera system. The series is priced like analog and delivers resolution like IP, but 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. Junction box included.
