The ADC-SEM-300 represents an enhanced iteration of the Alarm.com SEM210-VT communicator designed to work seamlessly with the Honeywell Vista10P, 15P, and 20P panels. This communicator facilitates signal transmission from your panel to Alarm.com and/or a central station, contingent on your service plan. While Alarm.com primarily emphasizes user-friendly self-monitoring via their customer portal or app, they also provide an affordably priced option for cellular signal transfer to a central station monitoring company if preferred.
