CSSS program provides effective premises guarding by means of a microphone or several microphones, which act as sensors and a modem, which acts as a signaling (informing) device. The CSSS principle of action consists in microphone (microphones) survey on the scale of real time and highly intellectual analysis of coming signals on the basis of special algorithms based on the methods of speech recognition. Due to the flexible system of tooling the user is able to adjust the action of the program himself in accordance with the specific requirements of the premises. The system can be adjusted for different frequency ranges and different levels of average total sound signals amount received from the microphone or all microphones in the system.
