Do different motion-sensing lights have different purposes?

Two main reasons for using these lights are safety and security. Safety lights illuminate dimly lit areas to prevent accidents while security lights help protect your property. Security lights tend to be more sophisticated than safety lights.

What's the difference between active and passive motion sensors?

Active-motion sensors detect how far away an object is by bouncing energy signals, such as infrared light, off objects and calculating how long they take to return to the sensor. This type of motion sensor is triggered easily. Passive-motion sensors detect heat and can be programmed to recognize heat levels typically emitted by a person.

What other factors should I consider?

Security lights use extra brightness as a deterrent. Safety lights just need to sufficiently illuminate the area. Motion-sensing lights with an adjustable range can be customized to the specified area.
