The core of the monitoring system


With the improvement of people’s security awareness, security monitoring products have been popularized in all walks of life, so consumers who apply security monitoring equipment do not know the core of the monitoring system? The following is a brief introduction.
1 System power supply The supply of power supply plays a vital role in ensuring the normal operation of the entire closed-circuit monitoring and alarm system. Once the power supply is damaged, the whole system is in a paralyzed state. The power supply of the system can be divided into two parts: centralized power supply and distributed power supply. Users can choose according to actual needs.
2 Control part This part is the core of the security monitoring system. It completes the digital acquisition of analog video surveillance signals. MPEG 1 compression monitors data recording and retrieves hard disk recording and other functions. Its core unit is the acquisition compression unit, which has channel reliability and processing power. The convenience of video retrieval directly affects the performance of the entire system. The control part is a key part of the linkage between alarm and video recording.
3 The anti-theft alarm part installs the active infrared probe at the important entrance and exit stairs, and deploys the alarm host in the monitoring room of the monitoring center duty room. Once someone enters the place, the probe automatically senses, triggers the alarm, and the host displays the alarm part. Linking the corresponding searchlights and cameras, and automatically switching to the alarm camera screen on the host computer, the alarm center monitoring computer pops up the electronic map and makes an alarm record, prompting the on-duty personnel to handle, greatly strengthening the security.
4 TV Wall Display Section This section performs real-time monitoring signal display and playback and retrieval of recorded content on the system monitor or monitor screen. The system supports multi-picture playback, simultaneous recording of all channels, system alarm screen sound prompts and other functions. It is compatible with the unobstructed monitoring functions of the traditional TV surveillance wall, and greatly reduces the work intensity of the duty guards and improves the reliability of security defense. The terminal display section actually completed another important job – control. This kind of control includes camera pan/tilt lens control, alarm control, alarm notification, automatic manual arming, security monitoring and anti-theft lighting control, etc. The user’s work only needs to click the mouse on the system desktop.
This is just a description of a typical security monitoring system. Different types of solutions will appear in practical applications. Security monitoring system solutions are generally tailored to the different requirements of security monitoring users.
