Once upon a time, all home security systems were hardwired. Connecting every sensor, keypad, camera and other peripherals required a technician to open up the walls, run wires to and fro, then patch everything together at the end — and then do it all over again if you need any maintenance, updates or changes. Wireless home alarm systems not only free us from those constraints, they introduce benefits that weren’t even dreamed up a few years ago.

If you’re looking for a home security system that’s versatile, inexpensive and isn’t a major home improvement project, wireless systems are a good choice. Check out our picks for the best wireless security systems you can buy, and the best practices for keeping your system safe and hack proof.

There are some cases when going wireless would be less than ideal. For example, if you live in a rural area without cellular coverage, you’ll have better connectivity with a system that incorporates a landline. The good news? These days, hardwired and professionally installed home security packages incorporate wireless elements. Even if the initial installation is a bit of a project, adding or upgrading peripherals like sensors, smoke and carbon monoxide detectors, security cameras and home automation devices don’t usually necessitate a system overhaul.
