4 Signals over 1 Coaxial Cable
HDCVI technology supports 4 signals to be transmitted over 1 coaxial
cable simultaneously, i.e. video, audio*, data and power. Dual-way data
transmission allows the HDCVI camera to interact with the HCVR, such as
sending control signal or triggering alarm. Moreover, HDCVI technology
supports PoC for construction flexibility.
* Audio input is available for some models of HDCVI cameras.
* The parameters and datasheets below can only be applied to A51-S2 series.
