Alarm.com ADC-SEM110-VT-VZ - System Enhancement Module (SEM) with Verizon LTE Cellular Communicator Reviews
Submitted on 05/07/2020 Alarm Grid
The Alarm.com ADC-SEM110-VT-VZ is a cellular communicator for a Honeywell VISTA P-Series System. But unlike most VISTA System Communicators, the ADC-SEM110-VT-VZ allows the system to connect with the Alarm.com servers for monitoring service. This is opposed to the AlarmNet360 servers that are more frequently used with Honeywell Alarm Panels. The ADC-SEM110-VT-VZ connects across the Verizon LTE Network, which is expected to be supported well into the very distant future. Overall, we really like the Alarm.com ADC-SEM110-VT-VZ, and we give it a 5 Star rating.
There are many positive aspects regarding the Alarm.com ADC-SEM110-VT-VZ. For one, it provides ultra-reliable connectivity through the Verizon LTE Network. This network is expected to be maintained well into the very distant future, even as Verizon inevitably releases their 5G network. The Alarm.com service is fantastic, as you can use it to control your system from pretty much anywhere in the world. We also like the fact that the ADC-SEM110-VT-VZ doubles as a Z-Wave Plus controller so that you can start building an automation network around your VISTA Security System. In fact, until the Honeywell PROA7 Panel, this represented the only method for using true Z-Wave Plus with a Honeywell System.
There are some small downsides to the Alarm.com ADC-SEM110-VT-VZ. For one, it is discontinued, and you will likely have trouble finding a new model. A used one should still work just fine, as long as it has been released by the previous monitoring company. There is no IP connectivity for the ADC-SEM110-VT-VZ. Newer Alarm.com Communicators allow for both IP and cellular connectivity, which is also referred to as dual-path connectivity. If you do not have internet service, then this is a moot point, but most users prefer to connect across both IP and cellular. Like any communicator, the ADC-SEM1110-VT-VZ must be installed.
We think the ADC-SEM110-VT-VZ is a great VISTA Communicator, and it gets 5 Stars from us.
Good: Alarm.com, Verizon LTE, Long-Term Solution, Z-Wave Plus
Bad: Discontinued, No IP Service, Must be Installed
Bottom Line: 5 Stars
