GSM Cellular Service


GSM (Global System for Mobile) is the standard for cellular networks throughout the world. When using a GSM based security system, your system communicates to our Central Monitoring Station via the cellular towers. A cellular number is purchased and activated specifically for your security system. This form of communication is commonly used either as a back up to a traditional POTS analog line or as a primary communicator.
