Video amplifier Features: The video amplifier is used to extend the range in Gira door communication systems with video function. It increases the level of the incoming video signal to the maximum permitted bus level and outputs this at the output. This compensates for the line attenuation from the source of the video signal to the input of the video amplifier. The combination housing allows three types of installation: Surface-mounted (in a standard junction box). Flush-mounted (in a device box). As a REG device (with the included REG adapter). Notes: With the video amplifier, the maximum cable length between the door and home station can be extended from 100 to 300 m. No further configuration is necessary during commissioning, as the video amplifier automatically adapts to the existing cable network.
