The PR300 has been specifically developed to counter act the latest technological advance of GSM based listening devices, making it an essential piece of equipment in the counter surveillance armoury.
The PR300 is designed to detect and locate transmissions from cellular mobile phone based devices, including mobile phones, vehicle trackers and 3G cameras. It is also an important tool for use in offices, hospitals, schools and prisons to prevent unauthorised mobile phone use, and in vehicles to locate hidden tracking devices.
It will detect signals from GSM900, GSM1800 and 3G (UMTS2100) devices whilst filtering out all other ambient signals to ensure that only the relevant devices are detected which helps to to prevent false alarms.
The internal ultra-high gain amplifiers ensure that signals can be detected from up to 10 metres (30 feet) away. The built-in signal strength meter (with optional audio beep tone) enables the precise source of the signal to be located with ease.
The band of the signal is also displayed to help confirm the Cellular network and the device type. The Burst Detection function ensures that short bursts, such as those from trackers or SMS (Text) messages will not go undetected. A 10 LED bargraph display indicates the signal strength along with an audio tone, enabling the operator to pinpoint the signal source precisely.
For discreet checking, without alerting others, the unit can be set to silent vibrate mode. If any signals are detected the unit will pulse vibrate silently, allowing the operator to monitor withouit alerting anyone else nearby.
The unit also incorporates a Digital Burst detector to ensure that short transmission bursts from trackers and other GSM/3G based devices are also detected. The user will be alerted even if a nearby unit has transmitted even for a fraction of a second.
The counter surveillance system is supplied complete with a tuned multi-band antenna and it also features a DC power socket for applications of long term use. The whole package is supplied in a protective foam-lined carry case.
