Abstract

A security system device including a single housing including at least a primary alarm sensor, an alarm verification unit, and processing circuitry. The primary alarm sensor is adapted to monitor a primary protected area and to generate a primary alarm signal when the primary alarm sensor is triggered. The alarm verification unit selectively provides verification information (e.g. video and/or audio signals) from at least part of the primary protected area to a central station monitor. The processing circuitry is adapted to generate an alarm enable signal when the primary alarm signal is generated. On the occurrence of an alarm enable signal, the processing circuitry generates an alarm detected signal and causes the alarm detected signal to be transmitted to a central station monitor, enables operation of the alarm verification unit, and enables transmission of the verification information from the protected area to the central station monitor. A secondary alarm sensor may also be included within the housing, in which case the alarm enable signal is generated only on the triggering of both the primary and secondary alarm sensors. The primary alarm sensor may be adapted to cause the sensitivity of the secondary alarm sensor to be modified on the triggering of the primary alarm sensor.
