GSM196 Cellular Detector

The GSM196 monitors the (E)GSM900, GSM1800 and WCDMA/UMTS 2100(3G) bands. It is designed to detect the presence of unauthorised mobile phones and then help locate them.

A 9-LED signal level display shows the strongest signal detected and helps to guide the operator to its source. This eases searching where several signals may be present. A cadenced vibrator (switchable and controllable) allows for covert use.

The GSM196 distinguishes between Network signals (text messages and registrations), GSM Calls, and 3G Calls, and indicates both current and past alarms separately for each type.

Two sensitivity ranges are provided. These are optimised for detection at a distance and location at closer ranges.

Use of nearby handheld PMR radios (walkie-talkies) is detected, 3G detection then being inhibited when they are seen to avoid spurious alarms.

For situations where greater accuracy is required and / or specific monitoring is required in areas containing multiple phones, a specially designed directional antenna SA918 system can be used with the GSM196 & GSM196A.

The GSM196A is set-up to the USA, Mexican and South American networks. This device monitors the GSM850, GSM1900, and WCDMA2100 (3G) bands.
