Dahua has simplified the installation of the HDCVI surveillance system with its Power over Coax (PoC) technology, which transmits both video, audio, control signal and electrical power over one coaxial cable, eliminating the need for separate camera power supplies and minimising operation costs.
The company has launched a range of new products based on PoC, including various types of HDCVI cameras, back-end recording devices and transmitters.
A star product of camera in the package, DH-HAC-HDBW2231R-Z-POC adopts 1/2,8-inch 2 Mp STARVIS CMOS image sensor and 2,7-13,5 mm motorised lens. Boasting advanced technologies, such as Starlight, 120 dB true WDR and 3DNR, it is able to capture images in extreme low-light or high-contrast conditions. The PoC camera supports both PoC and DC 12 V power input. In order to further facilitate system deployment, this model is designed with a power output port which can supply power for nearby device.
Strong enough to withstand impact up to level IK10, it features an IP67 rating and certifications include CE, FCC and UL.
Its PoC supplies 48 W in total and 12 W for each channel. It can do H.264+/H.264 dual-stream video compression and smart search and boasts an intelligent video system transmitting signals of audio and alarm via coaxial cable.
