In the United States courts, a motion for judgment as a matter of law (JMOL) is a motion made by a party, during trial, claiming the opposing party has insufficient evidence to reasonably support its case. [1] It asserts that the evidence allows only one result: victory for the moving party, even if a jury has found otherwise. [2]
Motion sensors create zones which cannot be accessed without sounding an alarm. Most cameras do now have a motion detection function, with some brands having thermal detection so they only activate when sensing a heat signature. This function is used so cameras do not pick up false alarms from trees blowing in the wind. [11]

Gyroscopes measure the angular rate of rotational movement about one or more axes. Gyroscopes can measure complex motion accurately in multiple dimensions, tracking the position and rotation of a moving object unlike accelerometers which can only detect the fact that an object has moved or is moving in a particular direction.
Alarms often come with a mix of features. Remote car alarms typically consist of an additional radio receiver that allows the owner to wirelessly control the alarm from a key fob. Remote car alarms typically come equipped with an array of sensors along with immobilizers and motion detectors. [citation needed]
