Frequently Asked Questions

When will my 3G cellular communicator lose network connection?

As nationwide cellular networks continue the conversion from older 3G coverage to newer, faster, and more reliable LTE, devices which communicate using 3G will become unreliable as the 3G network degrades until eventually, the 3G network will cease to function altogether. Without a network to communicate on, the 3G communicator in your security system will not be able to alert the local monitoring station so they can dispatch emergency services in the event of a threat or emergency.

Will I need to replace my whole security system to be protected?

No, you will not need to replace your entire system. 3G security systems can upgrade their cellular communicator to a faster, and more reliable LTE model, which preserves the original system but prevents interruptions in coverage by allowing it to communicate with new LTE networks. However, since there have been so many advances in security technology, integration, and accessibility since the installation of many 3G systems, we are offering an LTE security package to customers who want to upgrade their system to include more modern features.

Will the 3G Sunset affect my other security devices like cameras, sensors, etc.?

Your security devices such as cameras, sensors, etc., operate independent of the cellular network, and only communicate back to your security panel or recording device when they detect a potential threat. Since your security panel communicator is the device which communicates with local monitoring and emergency services, it is critical that it be replaced with an LTE cellular communicator in order to stay connected to the network. This will not affect your other devices as the security panel will still be able to communicate with them after the upgrade process is complete.
