This page covers two parts of the Bell System 4G GSM door entry range: the GT8 4G GSM controller and the ANT-4G/5M wall mounting antenna. The GT8 is the control unit for 1 to 8 way systems. With an entrance panel and a power supply, they make up Bell's GSM system, which lets visitors at a door or gate ring a mobile or landline.
The GT8 is a separate control unit in a weather resistant IP65 housing, which Bell says gives increased security. You choose your own SIM card and network, and Bell says no data plan is required. Programming is by SMS text message from anywhere. The antenna mounts on a wall and comes with a 5m lead. Bell says the wall-mounted antenna improves signal strength.
Choose GT8 for the control unit. It covers systems from 1 to 8 ways, so the same model is listed for every system size. Choose ANT-4G/5M for the wall mounting 4G antenna with a 5m lead. For reference, Bell lists a complete one-way system as a stainless steel panel, the GT8 control unit, an antenna with a 5m lead and a 13.8V DC 4A power supply.

Bell says you choose your own SIM card and network for the GSM system, and no data plan is required. A SIM card is not in Bell's list of what a complete system includes, so plan to supply your own.
The GT8 is the control unit of Bell's 4G GSM door entry system, for 1 to 8 way systems. In the system, visitors at the panel ring up to 3 mobile or landline numbers per call button, and residents can dial in to talk and unlock the door or gate. It is programmed by SMS text message.
Bell describes the GT8 as a separate control unit, weather resistant to IP65, for increased security. Bell's brochure does not give its dimensions or the cable distance allowed between the entrance panel and the control unit.
