With GSM phones getting ever smaller, they are increasingly being used in areas where they are forbidden. This technology is also becoming the preferred medium for bugs and other surveillance devices. To combat these problems, IPS offer two versions of mobile phone detectors together with one government only advanced system.

For operational reasons, detailed specifications and functionality of the governmant only equipment are not displayed here and are only available upon written request.

Advanced band-selection filtering coupled to unique signal-detection algorithms and easy-to-use displays gives unprecedented sensitivity and selectivity for this type of equipment.

The INTPRO 2G3G can detect both 2G (GSM900 & GSM1800) and 3G (WCDMA / UMTS 2100) mobile phones. For situations where greater accuracy is required and / or specific monitoring is required in areas containing multiple phones, a specially designed directional antenna system can be used with the 196.

You can set the INTPRO 2G3G’s range and sensitivity to either High or Low according to the application. The High range allows entire cell blocks to be swept, while the Low range helps locate the target mobile more accurately. An internal switch allow selection of either the two Handheld modes or the Static mode. Each mode has two sensitivity ranges which the user can select using the single control button.

In the Handheld mode, the presence and strength of detected GSM phone signals are shown by the Level bargraph display. The Type indicators flash rapidly to show whether the currently detected signal is a Network, 2G or 3G call. Once the signal has ceased, these LEDs flash slowly until the control button is pressed. Whenever the INTPRO 2G3G is operating, either the High or Low Range LED will be lit. Use the control button to step between ranges.

 Using the INTPRO 2G3G
The Handheld mode allows the user to walk around checking for threats. There are two modes, HV enables the cadenced vibrator and HO causes the unit to function silently. In this mode the brightness of the LEDs is automatically controlled with intensity being reduced under low ambiant light levels.

On the High range, detection range can be as much as 300m (in free space, for mobiles on full power). The Low range is used to pinpoint a phone’s location if a phone is transmitting on high power and the building materials allow easy passage of the signals to adjacent areas.

The Static (“mousetrap”) mode is normally used during sweep operations to detect the presence of mobiles for subsequent location. The Range switch allows the sensitivity to be set in advance according to the building’s construction (thicker walls mean more shielding of signals). In the Static mode the auto power off feature is disabled allowing the INTPRO 2G3G to be used for extended periods of monitoring specific areas.

We consider this item to be an essential part of a comprehensive sweep kit.
