CSSS - Computer Software Security System (sound version)

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. 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. So, it's possible to adjust the system e.g. for human steps only (low frequency sound signals) i.e. the level will start rising considerably after the appearance of low frequency sound signals.

It has been proved by practice that it is adjusting for low frequency signals (11 KHz) that is the most effective.

Remote Listening

Requirements

The main requirement for usage of this function is an availability in the voice modem of the mode Speaker Phone - SP. Such modems almost always have two inputs for earphones and microphone. In some soft-modems of such inputs no, but they can work through the interface DirectX - using an input and output of a sound card. Usage of such modems probably, but is not recommended.

Input password

The password is checked all time per 5 seconds. Therefore it needs to entered fast, and as it is not recommended to specify the password more than 5 digits. If the password nevertheless lengthy, try it to type very fast. If has passed more than 5 seconds, and SP has not joined, try once again, will not join yet.
