The device encodes an incoming digital audio and video signal (HDMI) originating from an external source (NVR/XVR) into a FullHD signal (MPEG-4/H.264) modulated in a digital television channel. The signal can be mixed with the DTT so it can then be distributed over a single coaxial cable and thus shown on all receiver devices in the system. It also has an HDMI feed-through to connect the input signal to the TV/Monitor. Configuration can take place via Blueteooth using the Comelit app MOD DVBT. Splitter included in the package.
