Dahua Technology has launched a new series of digital video recorders boasting stronger functions while saving a significant portion of wiring and power costs, thanks to the Dahua HDCVI PoC technology that enables transmitting video, audio, power and data over a single coaxial cable, benefiting Dahua customers and end users with true plug-and-play.
Dahua HDCVI PoC cameras come in two types: AT mode (maximum power consumption of 12 W or less) and AF mode (maximum power consumption of 6 W or less). The new series of recorders support full-channel Dahua AT and AF PoC camera access, regardless of different series and resolutions, with zoom or fixed lens. The PoC technology makes it possible for back-end recorders to provide instant power, through the same coaxial cable, to PoC cameras, which is a more stable way of energy supply.
Another improvement worth noting is the audio quality. Dahua’s PoC products support broadcast-quality audio, which is far better than ordinary coaxial cable transmission. Moreover, the new back-end products are smart enough to automatically tell if it is a non-PoC camera being connected to the system and decide whether to provide power or shut the power down in one specific channel, thus providing greater safety.
The beauty of coaxial cable power supply also lies in the much lower cost for users, since separate camera power supplies are no longer needed. Gone with front-end power sources is the complex work of wiring that can only be done manually. In areas where labour cost is high, Dahua’s new series of XVRs are likely to reduce the cost by half or even more.
As PoC technology keeps evolving, Dahua Technology has already been working on new PoC chips that will help to bring compatibility and stability to a new level in the near future.
