And, many of them don’t require any special tools or knowledge to get the job done. Professional installation was practically the only way to put in a home security system 15 years ago.

While some components might be affected momentarily by a power outage, cellular and landline systems will continue to work even if there’s no electricity. Cellular systems use cell towers to communicate with the monitoring center as well as a battery backup that can keep them up and running for several hours until the electric service is restored. Landline systems use traditional phone lines to communicate with the monitoring center and, just like cellular systems, they usually have a battery backup to keep them working for a set period of time.
