Module to incorporate in plates with viewer.

Digitizer module to be incorporated into MDS City door entry/video door entry panels.

It allows detecting the pressing of the panel call button and sending the corresponding code. It is also responsible for activating/deactivating the amplifier and the panel camera (if it is a video one), as well as the installation's video changer (if it exists). If the channel is busy, it turns on a STOP led and does not allow the panel to be used for a minimum conversation time.

It requires a viewer on the plate for its location.
