What Is The Best Cellular Communicator for a VISTA 21iPLTE?
The best cellular communicator for a VISTA 21iPLTE is the Honeywell Home LTE-21V. This is a plug-in LTE communicator designed exclusively for use with the VISTA 21iPLTE. It offers Verizon LTE service. A Honeywell Home LTE-21A with AT&T LTE service is expected to be released in the future.
The Honeywell Home VISTA 21iPLTE is a hardwired alarm control panel. The system includes a built-in IP communicator, which facilitates a wired ethernet connection. If you want to use cellular communication with the system, then you must add a cellular communicator. What's great about the VISTA 21iPLTE is that it supports some super convenient LTE cellular communicators that are designed exclusively for use with the system. These modules plug-in directly with the system board. This is very similar to how a VISTA-GSM4G connected with the older VISTA 21iP System.
As of late September 2019, the only plug-in LTE communicator for a VISTA 21iPLTE System is the Honeywell Home LTE-21V. This module communicates across the Verizon LTE Network. It will work great for anyone who receives adequate coverage from Verizon. However, there are some users who receive better coverage from the AT&T LTE Network. It is expected that a similar LTE-21A communicator with service from the AT&T LTE Network will be released sometime in the future. Unfortunately, that module is not available at the time of this writing. But once it is, then the best 21iPLTE cellular communicator will depend on whether you get better service from AT&T or Verizon.
By adding an LTE-21V or LTE-21A, your VISTA 21iPLTE will achieve dual-path functionality. If you enable both IP and cellular communication, then the system will utilize IP as its primary communication path. The system will only switch to its cellular backup if the internet is down or unavailable. This will help ensure that your panel is always able to maintain reliable connectivity with the AlarmNet360 Servers and Total Connect 2.0. Remember that you will need a monitoring plan with cellular service to activate a cellular communicator. Alarm Grid customers can choose between a Gold or Platinum Level Plan.
