What is a motion detector and how does it work?
A motion detector is a device that senses movement within a specific area. It works by emitting infrared rays or using passive infrared (PIR) technology to detect changes in temperature and motion. When a person or object enters the detection zone, the motion detector sends a signal to the connected device, such as a light or alarm, to turn it on or trigger an alert.
Motion detectors can be used in various applications, including home security systems, lighting control, and automation. They are often used to conserve energy by turning off lights or devices when no one is present. Some motion detectors can also be adjusted to detect movement within a specific range or sensitivity level, allowing users to customize their settings according to their needs.
Does a motion detector have a camera?
A standard motion detector does not have a camera. Its primary function is to detect movement, not to capture images or videos. However, some advanced motion detectors may come with a built-in camera, which can be used to capture images or videos when motion is detected. These devices are often referred to as motion-activated cameras or security cameras with motion detection.
It’s essential to note that not all motion detectors with cameras are created equal. Some may have higher resolution cameras, wider viewing angles, or additional features such as night vision or facial recognition.
