Dual Path (Cellular/ip) Digital Communicator

An electronic device that provides both internet protocol (ip) and cellular connection points for alarm monitoring purposes. this type of communicator hardware typically uses the ip path as the primary method because an ip signal can be constantly polled for connectivity. as soon as the ip signal is lost, the alarm communicator automatically switches to the cellular pathway. that method requires the use of a built-in sim card to communicate over an existing wireless network. a cellular/ip communicator sends alarm signals from the security system to the central monitoring station without the need for a pots line. dual path monitoring is more reliable than monitoring over a phone line because it has redundant signal communication paths.
