Description

A convenient motion detector

Technical Field

The utility model relates to the technical field of motion detectors, in particular to a motion detector that is easy to install.

Background Art

A motion detector is a device that detects moving objects, especially people. Such devices are often integrated as components of systems that automatically perform tasks or alert users to motion in an area. They are an important component of security, automatic lighting control, home control, energy efficiency, and other useful systems.

At present, in the prior art, most motion detectors are fixed on the wall by bolts. If the motion detector is fixed by bolts, when the motion detector needs to be removed, the wall needs to be destroyed, which makes the removal of the motion detector extremely inconvenient. In view of this, we propose a motion detector that is easy to install.
