The GSM interception system allows for real-time interception of telephone conversations and text messages sent through a GSM network. It is compatible with GSM 850/900/1800/1900 network and base transceiver stations all over the world. The GSM interception system supports A5.1 and A5.2 encryption algorithms used to encode phone calls over GSM networks. The system's range of operation has a radius of about 2 km, which can be extended up to 5.5 km with additional 50W power amplifiers. The GSM interception system is able to intercept 48/96 target phones simultaneously (with the ability to expand the system to support greater number of targets), depending on RF channels and the number of communication modules (in passive mode). Intercepted calls and text messages can be recorded and subject to further analysis. The device is operated through a PC software suite, included in the package.
Product description: Â yd-s1 human sensor intelligent voice reminder is the use of nine-core electronic intelligent mp3 music player chip for the processing core, tf card for the development of voice memory equipment.
