health.
They record a person's surroundings.

They record a person's surroundings.

Explanation:

Motion sensors like the passive infrared (PIR) work by detecting changes in the infrared radiation given off by objects in their surroundings. Normally most objects give off a small amount of infrared radiation. Human bodies, however, give off a large amount of infrared radiation.

So when motion sensors detect the presence of a person in a surrounding, they give off an alarm to indicate the presence of an intruder.
