Hybrid video recorder (HVR) by Dahua with resolution 4K and 8 channels. Hybrid video recorders (HVR) can be connected to both analog cameras, via coaxial cable, and IP network cameras, via ethernet cable or wirelessly, when both the recorder and the cameras have Wi-Fi connectivity. They are mainly used to replace older CCTV systems, which were exclusively connected to analog cameras, allowing the addition of network cameras. The number of channels of a recorder corresponds to the number of inputs it has for the wired connection of the system's cameras.
