Features

Features

  • The video amplifier is used to extend the range of Gira door communication systems to include video function.
  • It increases the volume of the incoming video signal to the maximum permissible bus volume and outputs it at the output. thereby compensating for the line attenuation from the source of the video signal to the input of the video amplifier.

The combination housing makes three mounting types possible

  • Surface-mounted (in a standard junction box).
  • Flush-mounted (in a device box).
  • As a DRA device (using the DRA adapter enclosed).
