This discreet audio surveillance system can be installed covertly in buildings or vehicles. It is activated by dialling in from any telephone. It will silently answer the call and allow the area to be audio monitored. Within the UK, It employs a mobile phone GSM SIM card with an untraceable, unlisted and previously unused number. This has the added benefit of no subscription charges. The size and robust construction of the device allows flexibility in deployment. Additionally, it offers superb audio quality, using the very latest Knowles microphone. To ensure continual monitoring, it utilises a built-in standby battery for use in the event of temporary power disconnection. |
