The Type of Motion Detector and the Response Triggered

When looking to purchase a motion detect, you should determine the type that suits your situation. For example, large areas require a sensor that can detect fluctuations in the levels of heat. Also, consider what the sensor triggers in response to an interruption. Motion detectors can trigger the light, alarm, video camera, or all three combined.

Alarm-Triggered Motion Detectors

Most motion detectors trigger alarms when they go off. The alarms range from audible to silent alarms that notify the user, the monitoring company, and the police of any intruders.

Motion detectors can also use light as a deterrent to criminals. When lights are well positioned, they give maximum coverage to an area. They turn on when they sense motion in the area. They include light and laser beams in entrances and doorways.

Some motion detectors respond as video surveillance when triggered. The video surveillance records footage of activities like break-ins. They cover all areas, including blind spots. In most cases, they are used alongside alarms and lights for higher coverage.

Detection Range and Zone

The motion detection range and zone are connected areas that are very important to your home security. The detection zone is the width of the area covered by a motion detector. The zone varies with the type of motion detector. When purchasing your detector, ensure that it has adequate detection zone to provide the needed coverage.

The detection range is the maximum distance covered by the motion detector. You should shop for motion detectors that have an adjustable range.

The Detector’s Sensitivity
