Infrared sensor

« Back to Glossary Index

In the commercial and residential burglar alarm industry, an infrared sensor is a crucial component of a security system. It is a device that detects motion by sensing changes in temperature. When an intruder enters a room, their body heat will trigger the sensor, which will then send a signal to the alarm system to sound an alert. Infrared sensors are commonly used in areas where there is a high risk of break-ins, such as entryways, windows, and hallways.

Infrared sensors are highly effective in detecting intruders because they are not affected by changes in light levels. They work by detecting the heat signature of a person or object, which means they can detect movement even in complete darkness. This makes them an ideal choice for areas that are not well-lit or where lighting conditions may change frequently.

1. What is an infrared sensor in a burglar alarm?

An infrared sensor is a device that detects changes in temperature and movement within its range. In a burglar alarm system, an infrared sensor is used to detect the presence of an intruder by sensing their body heat and movement.

2. How does an infrared sensor work in a burglar alarm?

An infrared sensor works by emitting infrared radiation and then detecting the radiation that is reflected back. When an intruder enters the sensor’s range, their body heat and movement will cause a change in the reflected radiation, which triggers the alarm.

3. What are the benefits of using an infrared sensor in a burglar alarm?

Using an infrared sensor in a burglar alarm system provides several benefits, including high accuracy in detecting intruders, low false alarm rates, and the ability to detect movement even in low light conditions. Additionally, infrared sensors are easy to install and can be used in a variety of settings, making them a popular choice for home and business security systems.
