GSM Intercom, Access Control And Alarm System Intro:

It has a wireless intercom in front of your gate that includes a speaker, a microphone and a "Call" push button. When the "Call" push button is pressed by a visitor, the system will call the owner's phone number automatically via the GSM /UMTS network allowing him to speak to the visitor in spite of the location of the telephone being called. Communicate and allow entry from anywhere in the world as there is no limitation on the distance as to how far the system works. No longer let visitors realise you are out or away as every time the Intercom button is pressed a call is made to your mobile. Should the visitor require access to your property when you are not there, opening the door or gates is a simple matter of adding a number into your phone.
