Various intercoms are available on the market, LHV prefers to use Kocom intercoms, as this brand is tried and tested, reliable and supported by E.T systems.
The 1-to-1 voice-only Kocom intercom system has one handheld door station, and an outside unit with speaker. This is the most basic and cheapest intercom system that LHV Garage Doors & Gates installs. 1-to-2 Kocom systems are also available, where there are two handheld door stations.
Video Kocom intercoms are also on the market, in black and white or full colour, but are more expensive than the standard intercoms. The latest addition to the Kocom, is a modern, full-colour hands-free video intercom.
All Kocom intercoms can be wired up to open an electric lock or an automated gate, from the inside door station.
