AJ-300

It simultaneous detects four bandwidths (GSM, DCS, CDMA, 3G) transmission signal. Each band is designed with individual detection circuit for high sensitivity and consistency. It can look through the mobile 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. Broad band Log Amplifier design. Active striping filter designed for high selectivity and low false alarm. It has the power-line data communication circuit and uses AC power line to send operational status and receive control signal.

Application Introduction

It is specifically designed for immediately detecting transmission signals of any mobile phone within its effective range, then send out alarm signals or voice to the monitoring staff. It can also link with mobile 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 mobile 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.
