An intervention service is a security service that responds quickly and purposefully to particular events. It acts on arrangements agreed in advance, whenever an alarm is triggered or a hazard arises.
Duties
- Responding to alarms: the intervention service is deployed quickly to check the cause of the alarm and establish what is happening.
- Maintaining security: it protects people and property by being present on site and, where necessary, alerting the police or emergency services.
- Surveillance: modern technology such as cameras and motion detectors raises the level of security.
The intervention service is the part of the security chain that responds on the ground to an alarm raised in the emergency call and service control centre.
