What Is Safewatch Cellguard and How Does it Work?

Written by | Updated May 20, 2019

For homeowners who rely on the comfort of 24/7 security monitoring, the only threat to that peace of mind is usually an interruption to the home phone line, which connects the home and the monitoring center. ADT eliminated that threat with their Safewatch CellGuard® monitoring service that utilizes a cellular phone connection rather than a land line. And in a time when more families are choosing to disconnect their home land line and go 100% cellular, it makes sense to have security options available that don’t rely on a land line.

Safewatch CellGuard® provides entirely wireless security monitoring, which means ADT delivers reliable security monitoring to help keep your home and loved ones safe without requiring the extra expense of a home phone line.

This optional upgrade for ADT monitored security customers uses cellular technology to help ensure ADT’s network of command centers remains connected to customers during a power outage, when phone lines are down or in the absence of a home phone line.

All that is required to take advantage of the extra security offered by CellGuard® is a cellular transmitter installed on the customer’s property. The transmitter provides the same reassurance of 24/7 monitoring that previously required a home phone. And customers can use their existing cell phone-there’s no need to switch plans or carriers because Safewatch CellGuard® works with any cellular phone.

If you do have a home phone you can still take advantage of the extra security provided by Safewatch CellGuard®. Your land line can be used as the main line for your home security system, and CellGuard® becomes a backup if there is a blackout or telephone outage. Essentially, in daily situations, your cell phone takes a back seat while your land line works as the primary link for communication with the security company. But in the event of an outage or other interruption to your home phone service, CellGuard® helps keep you safe and connected by defaulting to your cell phone so that you and your family wont lose a moment of security.

Because CellGuard® can be used solely with a cell phone or as a backup to an existing home phone line, SafeWise believes it’s a great fit for customers who experience spotty land line coverage or those looking to discontinue their home phone service. We also recommend considering CellGuard® if power outages are a regular concern in your area and you want to help ensure outages won’t cause a security breach.
