What equipment does the monitoring system have?

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The surveillance system is also called a closed-circuit television surveillance system (English: Closed-Circuit Television, abbreviated as CCTV). A typical surveillance system mainly consists of front-end audio and video collection equipment, audio and video transmission equipment, back-end storage, and control It consists of five major parts including display equipment and display equipment. The back-end equipment can be further divided into central control equipment and sub-control equipment. Front-end and back-end equipment are constructed in various ways, and the connection between them (also called a transmission system) can be achieved through coaxial cables, twisted pairs, optical fibers, microwaves, wireless and other methods.

Equipment introduction

Front-end monitoring equipment introduction

  • Camera: Adopting advanced charge-coupled device CCD image sensing technology. Users can choose from cameras with automatic aperture interface, automatic white balance, electronic shutter, illumination requirements, backlight compensation, standard definition or high resolution, suitable for various occasions. Can be divided into:

    • Black and white camera: economical and practical, with super-class clarity and sensitivity;

    • Color camera: high definition and color Form a sharp image contrast;

    • Hemispheric black and white/color camera: economical and convenient, comes with its own lens and mounting bracket, and can be coordinated with the surrounding environment;

  • Lens: Adjust the camera range by changing the lens to obtain a suitable image. The lens can be matched with a series of cameras. Divided into: fixed focus lenses and zoom lenses. Fixed-focus lenses are available in wide-angle, standard and long focal length types. You can also choose a manual aperture lens suitable for use in places with constant lighting conditions or an automatic aperture lens suitable for use in places with frequent changes in lighting conditions; the adjustment of the zoom lens can meet the needs of the subject. Field of view requirements.

  • Infrared light projector: Provides the lighting needed for the camera to work at night.

  • Camera protective cover and bracket: effectively prevent human damage to the camera, and play the role of waterproof, dustproof and fixed. Omni-directional pan/tilt: It can rotate up, down, left and right to achieve all-round monitoring.

  • Pan/Tilt Lens Controller: Remotely control the on-site pan/tilt to rotate in all directions and adjust the focus and aperture of the camera lens.

  • Monitoring head: While monitoring the live image, it can monitor the live sound with high sensitivity.

  • Monitor: Display the image picked up by the camera with high quality. There are various sizes of black and white and color monitors to choose from.

Introduction to terminal monitoring equipment

  • Sequential video and audio switcher: can switch from 2 to 12 channels The camera image and the corresponding audio signal are switched in sequence, and the time sequence switching image signals are automatically displayed on the monitor in sequence, and the switching time can be adjusted. You can also manually switch to select or bypass the image display of a designated camera.

  • Video image processor: Use the video image processor to split and display multiple images on a monitor screen at the same time, or you can select one of the multiple images to fill the screen. show. It has an alarm input interface, which automatically switches to display the full-screen image of the corresponding camera when an alarm occurs. More advanced model processors have video playback control functions.

  • Matrix switching controller: Pre-programmed to control video and manage alarm input and output.

  • Professional video recorder: Using a box of ordinary household video tapes, you can easily record all camera images and audio signals of the system for 24 hours or even 168 hours to 960 hours. The management is simple and convenient; during video playback , with the video image processor, it can display multi-screen split images and manually switch to display the full-screen image of a certain camera; abnormal image confirmation can be performed during high-speed playback; upon receiving the alarm signal from the sensor, the video recorder can be automatically started or converted to real-time Recording status; the monitor displays operating procedures and function menus.
