Two new product releases bring DualSIM to most DMP control panels. TMSentry is designed specifically for monitoring teller machines. It easily accommodates new, slimmer ATMs and ITMs, or serves as a space-saving upgrade to existing teller machines. In addition to built-in DualSIM communication, new TMSentry updates include four additional zones with zone expansion (up to ten total zones), as well as supporting Virtual Keypad and Entré end user system management tools. In addition, a DualSIM version of the 263LTE Cellular Communicator is now available. The 263LTE module provides optional cellular communication for XR, XF6 and XT Series control panels — including the new XT75. These fully supervised signals are sent directly to the monitoring center without going through a network operations center (NOC). A FirstNet-approved version of the 263LTE is also available. DualSIM functionality allows one communicator to transmit signals over Verizon and AT&T networks — a feature rapidly growing in demand. When both carriers are activated, the control panel chooses a primary cell carrier based on signal strength and checks its signal every hour. If the signal strength indicates risk of losing connection, the system automatically switches to the second carrier if its signal is better.
