Liiketunnistimi, also known as a motion detector, is an electronic device that senses and records changes in motion within its field of view. These sensors detect movement through various technologies such as infrared, radar, acoustic, ultrasonic, and visual‐based motion detection. They have become integral components of security systems, automatic lighting, energy‑saving controls, and home automation solutions.
Infrared sensors, the most common type, monitor changes in passive infrared radiation emitted by warm objects.
Motion detectors can be installed as standalone devices or embedded in broader systems. In residential settings,
Despite their utility, motion detectors have limitations. They can generate false positives from pets, wind or
In recent years, integration with wireless networks and IoT platforms has expanded their functionality. Smart motion
