I have a DSC Neo panel with a DSC TL280 Ethernet-only internet communicator. Can this be used to connect to alarm.com and surety? Or, do I need the LTE communicator?
No, to get connected a 4G LTE model is required. Cellular connectivity is required for all Alarm.com accounts using a security panel. Look for TL880LT models
Thank you for the quick reply. If I purchase an LTE communicator, do I need to add a cellular line to my family cellular account? Or, does the surety account include the cellular plan?
No, the cellular service is included in the Surety plan price. You do not need to maintain any separate cell account.
