GSM jammers

It is well known that cellular phones might be used for eavesdropping as bugging devices. Spy phones and remotely activated telephones can be easily hidden in high-security facilities like military headquarters, briefing rooms, banks, etc., where sensitive information is in jeopardy of being tapped. Using cell phone jammers neutralizes this threat. Once a cellular jammer is operating, all mobile phones present within the jamming coverage area are blocked, and cellular activity in the immediate surroundings (including incoming and outgoing calls, text messages, pictures and multimedia sending and receiving, etc.) is blocked.

SEL SP-162 "Batog" - cellular jammer

The device is designed to prevent cellular communication in designated areas. Based on advanced cellular jamming technology, the jammer transmits RF signal which block the communication between the mobile phone and the cellular base stations, thus paralyzing the operation of cell phones. This neutralizes the threat of being tapped with the help of cell phones, prevents illicit telephone conversations and provides a silent work environment in a given area. Moreover, mobile phone jammer provides an easy to operate solution against the universal threat of using cellular phones as bomb’s triggers.
The basic version of SEL SP-162 Batog is able to block cellular networks of CDMA-450, GSM-900, GSM-1800 and UMTS standards. Upon customer’s request the jammer can be manufactured with 4 bands of any other cellular standards.

Intellectual cellular jamming system in combination with ST-062

In this mode the ST-202 UDAV-M is connected to the detector of mobile digital communication devices ST-062 with a special cable. Upon detection of digital signals (DECT, GSM, BLUETOOTH, WI-FI, 3G, etc.) by ST-062, ST-202 UDAV-M becomes active for 1 minute. Within 30 sec. of deactivation ST-202 returns to detector-controlled mode.
