Underground sensor

« Back to Glossary Index

An underground sensor is a device used in the burglar alarm industry to detect movement or vibrations beneath the ground. These sensors are typically installed in the ground around the perimeter of a property and can detect any activity, such as digging or tunneling, that may indicate an attempted break-in. The sensors work by detecting changes in the ground’s vibrations caused by movement, and then sending an alert to the security system’s control panel. This allows the system to quickly respond to any potential threats and alert the authorities if necessary.

In the commercial and residential burglar alarm industry, underground sensors are an important component of a comprehensive security system. They provide an additional layer of protection against break-ins and can help to deter potential intruders. By detecting activity before a break-in occurs, underground sensors can help to prevent property damage and theft, as well as protect the safety of those inside the building.

1. What is an underground sensor in the context of burglar alarms?

An underground sensor is a type of security sensor that is installed underground and detects movement or vibrations caused by an intruder attempting to enter a property. It is commonly used in outdoor areas such as driveways, gardens, and perimeter fences.

2. How does an underground sensor work?

An underground sensor typically consists of a buried cable or probe that emits a low-level electrical signal. When an intruder steps on or disturbs the ground above the sensor, the signal is disrupted, triggering an alarm or alert. Some sensors may also use acoustic or seismic technology to detect vibrations caused by digging or cutting.

3. What are the benefits of using an underground sensor for burglar alarms?

Using an underground sensor can provide several benefits for home or business security, including early detection of intruders before they reach the building or property, reduced false alarms from animals or environmental factors, and discreet installation that does not detract from the appearance of the property. Additionally, some sensors may be integrated with other security systems, such as cameras or lights, to provide a comprehensive security solution.
