The GB2™ series, simply put, is our lowest cost multi-family video-intercom system. The GB2™ series connects to two (2) non-polarized wires and can handle up to 256 apartment monitor stations and up to four (4) door entry stations.
While the GB2™ series color video-intercom is designed primarily for use in multi-family (apartment house) or commercial office buildings, it can also be used in residential applications, in "villa mode". The GB2™ series features a choice of the VESTA2 GB2 (4.3") videointercom monitors or the THERA GB2 (7.0" touchscreen) videointercom monitors.
Options include multiple entrance capability, audio only intercom handset stations, secondary (single or multiple) camera switching and multi-relay outputs.
The GB2™ series door stations are available in the NEXA Aluminum or St. Steel finish, and can be flush or surface mounted.
The GB2's system uses simple 2-conductor non-polarized wiring making it ideal for new installations as well as for retrofit applications. All audio, video and data functions are fully digital and using the RAP-2150 cable you can run up to 300 meters from the entrance panel to the furthest monitor.
For CAT5 Cabling, the 4 solid color wires must be joined together as one, and the 4 striped wires must also be joined together as one to create your 2-wire cabling structure.
