Common Security System Service Questions

When removing an old security alarm system, you likely won't need to remove any of the wiring. Wiring can either be left in place for a replacement system or capped off for safety and pushed into the wall. If you're uncomfortable with the wiring, or if it's badly damaged, contact a professional electrician for assistance with safe removal.

There are ample home security options available today outside of just window bars. Depending on your location, home’s layout, and needs, one or more types of home security systems may be necessary. You could consider doorbell cameras, motion-sensor flood lights, or window and door sensors. And in some cases, you may qualify for homeowners insurance discounts when you install one or more.

A home security system usually houses its battery (or backup battery) within the control panel. That’s the panel where a touchpad and screen can usually be found. Some people place the control panel in a hard-to-reach spot, like a basement or closet, so that it can be cool and dry and hard to find by intruders. If you’re unable to find the battery in your security system, consult your manual or call the manufacturer. 

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.

This is the topic of much debate, though there is no “better,” as it depends on personal preferences. Some of the components of a wireless system keep working when the power goes out, as they are battery-powered. On the other hand, a wireless system typically connects to your modem and router. Wired systems use landlines to communicate, which never go out on their own unless they’re physically cut.
