GSM Audio Intercoms GSM intercoms work via the normal mobile phone network. A SIM card either pay as you go or contract (most networks) is used inside the unit. When a visitor presses the call button at your gates, the normal house phone or mobile is called. (call charges apply). You can talk to your visitor and open the gates via your telephone keypad. If there is no answer, the GSM unit will redial up-to 2 additional numbers (depending on model). Permitted users can open the gate by calling the GSM unit with their mobile with NO CALL COST (most models) GSM intercoms overcome the cost and difficulty of installing cables from your intercom call point back to your home or office. In addition the offer more features than any other type of intercom. Unlike wireless intercoms, there is no range limitation. Check with network provider regarding GSM coverage.
