Product Description
Application Introduction:
It is specifically designed for immediately detecting transmission signals of any Mobil phone system within its effective range, then send out alarm signals of voice to the monitoring staff.
It can also link with Mobil phone jamming device (optional) through its own AC power socket and prevent concerns over the always-on broadcasting of jamming electro-magnetic waves.
The actual operation is started by conducting detection within its range first. It will not activate the jamming device if there is no transmission signal around. Once there is any Mobil phone signal present, it will immediately inform the jamming device to activate the jamming broadcasting. The whole operation and response do not exceed 20 ms time.

Product Highlights
Is simultaneous detects four bandwidths (GSM/DCS/CDMA/3G) transmission signal.
Each band is designed with individual detection circuit for high sensitivity and consistency.
Broad band Log Amplifier design.
Active striping filter design for high selectivity and low false alarm.
It can look through the Mobil phone signal and automatically activate the jamming device to break the communication when needed. Therefore it can eliminate the health concern of always-on jamming radio wave to human body
