Volumetric sensor

« Back to Glossary Index

A volumetric sensor is a type of sensor used in burglar alarm systems to detect movement within a specific area. This type of sensor is designed to detect changes in the volume of the space it is monitoring, such as a room or hallway. When someone enters the monitored area, the sensor detects the change in volume and triggers an alarm. Volumetric sensors are commonly used in both commercial and residential burglar alarm systems to provide an added layer of security.

In commercial settings, volumetric sensors are often used in conjunction with other types of sensors, such as door and window sensors, to provide comprehensive security coverage. They are particularly useful in large open spaces, such as warehouses or retail stores, where traditional sensors may not be effective. Volumetric sensors can also be used to monitor areas that are difficult to secure, such as outdoor storage yards or parking lots.

In residential settings, volumetric sensors are often used to monitor common areas of the home, such as living rooms or hallways. They can also be used to monitor areas that are particularly vulnerable to break-ins, such as basement windows or sliding glass doors. Volumetric sensors are an effective way to provide added security to a home without the need for additional sensors or equipment.

1. What is a volumetric sensor in a burglar alarm system?

A volumetric sensor is a type of motion sensor that detects changes in the volume of a monitored area. It uses infrared technology to detect movement and can cover a larger area than traditional motion sensors.

2. How does a volumetric sensor work?

A volumetric sensor emits infrared radiation and measures the reflection of that radiation. When an object moves within the monitored area, it causes a change in the reflection of the infrared radiation, which triggers the alarm.

3. What are the benefits of using a volumetric sensor in a burglar alarm system?

Volumetric sensors are more effective than traditional motion sensors because they can detect movement in a larger area. They are also less likely to trigger false alarms because they are not affected by changes in temperature or air currents. Additionally, they can be used in a variety of settings, including homes, businesses, and outdoor areas.
