Alarm Systems Peripherals
SMS via GPRS
GSM devices are ideal as an alternative way of communication between security systems, so that if for some reason the phone line is cut off, all calls are made through these devices. They are also used to enable automation, as users can open/close contacts by sending the appropriate SMS text message and automatically send SMS when one of the contacts opens or closes.
The unique design of the peripheral alarm systems, allow the easy adjustment of each installation to the customer’s need with many options and mounting possibilities.
