An outdoor motion sensor light offers security and illumination. Our home security expert recommends six models, including battery- and solar-powered lights.

The best home security systems are 1. SimpliSafe, 2. Ring, 3. Abode, 4. Arlo, 5. ADT and 6. Vivint. They include sensors, detectors, cameras and more.

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.
