It is specifically designed for immediately detection transmission signals of any Mobile Phone system 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 round. 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 minutes.
