What Is a Digital Security System?
The digital monitoring system refers to processing the images collected by the surveillance camera into digital signals through software and hardware, and transmitting them to a computer for processing. For the digital monitoring system, according to the different functions of each part of the system, we divide the entire digital monitoring system into seven layers-the presentation layer, the control layer, the processing layer, the transmission layer, the execution layer, the support layer, and the acquisition layer. Of course, due to the increasing integration of devices, for some systems, some devices may exist in the system as multiple layers at the same time.
Digital monitoring system
- Networking
- The monitoring enters the computer network, and the leadership sub-control is realized on the office computer.
- Digital
- The surveillance image, control and alarm information are digitized and then entered into the computer, which can make full use of high-tech means for system management and image processing.
- Wide area
- Can achieve a wide range of monitoring and alarm networking throughout the industry.
- Intelligent
- The software performs intelligent classification and processing of various monitoring and alarm information, detection data, etc., and can determine the monitoring and alarm operation process according to the requirements of different users.
- Functions of digital monitoring system
- Monitoring function
- Image switching, multi-screen viewing, PTZ and lens control, PTZ preset (128 preset positions), computer digital video recording, management and recycling, image sharpness (speed) adjustment.
- Alarm function
- Alarm input, fire prevention, anti-theft, ambient temperature and humidity, equipment operation failure, accident and other alarm sources.
- Alarm linkage: Once an alarm occurs, the system will automatically record when the linkage occurs, send an alarm, turn on the lights, remotely transmit to the control center, and the center will give a voice prompt.
- Multi-channel alarm: The center can simultaneously receive alarms from multiple substations.
- Control function
- Remotely control lighting, air conditioning, alarm fortification or disarming, remote reset of front-end failure, ambient temperature, temperature measurement of key parts.
- Management functions
- On-duty personnel and leaders have separate control management, system operation log, alert handling, and online sub-control priority management to ensure the safe operation of the system. Lead the sub-control management, system operation log, alarm handling, and online sub-control priority management to ensure the safe operation of the system.
- Several solutions of digital monitoring system cannot open
- 1. If it is a PC type, remove the acquisition cards of the same brand and the same number from other machines and install them on this machine to see if the acquisition card is broken.
2. If the problem is still the same, it means that the capture card is not bad. It is recommended to reinstall the capture card driver (when installing the driver, be sure to check the driver installation instructions for details), and then restart the machine to try.
3. If reinstalling the capture card driver still does not work, then reinstall the operating system, then reinstall the capture card driver, and finally don't forget to restart the machine to try, it should be OK.
4. If it is an embedded machine, send it to the repair point on the warranty card or the sales company to check it. It should be an unrecoverable failure of the hardware system or software system.
