TracSure(tm) Alert is a Quad-band jamming signal detector, for personal (pocket or held) and vehicle-mounting (shown with cables for 12v supply and external antenna option). The device is always-on, and monitors the GSM bands for the presence of a wide-band non-GSM signal. The presence of weak jamming signals (may cause unreliable speech) is identified by a red LED. When stonger jamming is detected (will render GSM comms inoperable), a klaxon-like noise is sounded in addition.
TracSure Alert gives vital time for security-aware users to react to a potential threat, so they may avoid assaults on their vehicle, assets, or person. The unit will send date/time/position/strength and duration of jamming signals to a server, when normal GSM service is resumed.
An optional GSM signal mapper records GSM signal strength in its vicinity, and provides postiion/signal-strength/time reports to a nominated server. This allows secure journeys to be planned in advance, avoiding low signal areas.
TracSure is able to guard against 3G jamming threats, as most jamming devices broadcast a wide-band noise signal that encompasses all 2G/3G bands simultaneously.
