Video multiplexer features: The video multiplexer bundles the video signals from the door stations, TKS camera gateways and TKS IP gateways. One video multiplexer can combine the video signals from three door stations with color cameras. With two video multiplexers, the video signals from up to five door stations can be combined. The combination housing allows three types of installation: Surface-mounted (in a standard junction box). Flush-mounted (in a device box). As REG (with the included REG adapter). Notes: No further configuration is necessary when commissioning, as the video multiplexer automatically adapts to the existing cable network.
