Where should I put a motion sensor?

How high should motion sensors be placed?

Ideally, it's best to mount motion sensing lights six to 10 feet above the ground and positioned so that most movement will occur across the sensitivity zone, rather than directly toward the detector.

What windows should I put security sensors on?

No, you don't need a window sensor on every window. You'll want to put them on ground-floor windows and those that you believe an intruder could access. You should also put them on any windows you want to monitor in case someone inside the house (like an adventurous teen) tries to slip out.

Should I put window sensors on all windows?

No, you don't need a window sensor on every window. You'll want to put them on ground-floor windows and those that you believe an intruder could access. You should also put them on any windows you want to monitor in case someone inside the house (like an adventurous teen) tries to slip out.

Are motion detectors worth it?

Motion detectors are best at detecting once an intruder has already entered, while window sensors are better at detecting the actual intrusion attempt. For most people, both of these things are going to be worthwhile.
