Infrared motion sensor technology

« Back to Glossary Index

Infrared motion sensor technology is a crucial component of modern burglar alarm systems. These sensors detect changes in infrared radiation, which is emitted by all objects with a temperature above absolute zero. When an intruder enters a room, their body heat will cause a change in the infrared radiation detected by the sensor, triggering an alarm. Infrared motion sensors are highly effective at detecting intruders, as they are not affected by changes in light levels or shadows, and can detect movement even in complete darkness.

In addition to their effectiveness at detecting intruders, infrared motion sensors are also highly versatile. They can be used in a wide range of settings, from small residential properties to large commercial buildings. They can be installed in a variety of locations, including ceilings, walls, and corners, and can be configured to detect movement in specific areas or across entire rooms. Some infrared motion sensors are also designed to be pet-friendly, meaning they will not trigger an alarm if a small animal enters the room.

1. How does infrared motion sensor technology work in burglar alarms?

Infrared motion sensor technology works by detecting changes in heat patterns within its range. When an intruder enters the sensor’s range, the sensor detects the change in heat pattern and triggers the alarm. The sensor emits infrared radiation and detects the reflection of that radiation off of objects in its range.

2. What are the benefits of using infrared motion sensor technology in burglar alarms?

Infrared motion sensor technology is highly effective in detecting intruders, as it can detect even the slightest movement within its range. It is also less prone to false alarms caused by pets or other non-threatening movements. Additionally, infrared motion sensors are easy to install and can be used in a variety of settings.

3. Are there any limitations to using infrared motion sensor technology in burglar alarms?

One limitation of infrared motion sensor technology is that it can be affected by changes in temperature, such as drafts or sunlight. Additionally, if the sensor is not properly installed or calibrated, it may not detect intruders or may trigger false alarms. It is important to ensure that the sensor is installed correctly and regularly maintained to ensure its effectiveness.
