<p>A silent intruder alarm system is provided for alerting a user to an article 100 being breached or compromised. If an intruder interferes with the secured article 100, a sensor 70 of a security device detects an event associated with an article 100. This detection will trigger (via a processor 80) an alarm condition, and a transceiver 90 will send an alarm signal 20 to a monitoring device 10 over a communication network 50. No indication of the alarm condition is detectable outside the housing 40 by means other than via the alarm signal 20. In this way, an intruder compromising an article 100 is not alerted to detection of the event by the sensor 70. Therefore, authorities may be summoned to apprehend the intruder without the intruder being provided with an opportunity to escape. The monitoring device 10 can remotely control the security device over the network 50. The monitoring device 10 may comprise a mobile phone, smartphone, tablet or computer. The monitoring device 10 may be arranged to run an application for monitoring and/or controlling the security device.</p> |
