Maddy wants to install a camera system but worries about how much storage space the recorded videos will use. Technology for motion detection can be useful here.
A change in an object's position in relation to its surroundings or a change in the environment in relation to an object is what is known as motion detection. It can be done using mechanical or electronic techniques. Motion perception is what happens when it happens in living things.
Optical and auditory signals are the two main ways that motion can be detected electrically. For optical detection, laser or infrared technologies may be employed. An infrared disturbance is picked up by a sensor in motion-detection devices like PIR motion detectors. A signal may then trigger an alarm and/or a camera to record a picture or a video of the incident.
