Wuxi Security Monitoring What are the basic functions of the system?
Wuxi Security monitoring The system can reflect the monitored objects in real time, vividly and truly, which not only greatly extends the observation distance of the human eye, but also expands the function of the human eye. It can replace manual monitoring for a long time in harsh environments, so that people can see all the actual situations on the monitored site and record them through the video recorder. At the same time, the alarm system equipment will alarm for illegal intrusion, and the alarm model generated will be input to the alarm host, which will trigger the monitoring system to record.
The main application scenarios of Wuxi security monitoring system are: video monitoring, alarm prevention, smart home, background music, Access control attendance Parking lot, etc. Shanghai Monitoring Engineering
What parts does the security monitoring system include?
Wuxi security monitoring system, according to the different functions of each part of the system, we divide the entire security monitoring system into seven layers and one performance city, which is intuitive to us. It shows the quality of the entire security monitoring system. Such as monitoring TV wall, monitor, high tone alarm horn, alarm automatic connection telephone, etc., all belong to this floor.
1. The control layer is the core of the entire security monitoring system, which is a clear reflection of the system's scientific and technological level. Usually, we have two choices of control mode, which should be digital control. Digital control takes the industrial control computer as the control core of the monitoring system. It changes the complex analog control operation into simple mouse click operation, which will greatly simulate controller The stack is reduced to an industrial computer, and the complex and large number of control cables are changed into a serial telephone line. It turns the medium and remote monitoring into reality, the host is very expensive, the module is wasted, the system may collapse in the whole line, and the control is lagging behind.
2. The processing layer may be called the audio and video processing layer. It distributes, amplifies, segments, etc. the audio and video signals sent from the transmission layer, and organically connects the presentation layer and the control layer. Audio/video distributor, audio/video amplifier, video splitter, audio/video switcher and other equipment belong to this layer.
3. The transport layer is equivalent to the blood of the security monitoring system. In small security monitoring systems, our common transmission layer devices are video lines and audio lines. For medium and remote monitoring systems, we often use radio frequency lines and microwaves. For remote monitoring, we usually use the network to run up, which is theoretically non attenuation. This ensures the lossless display of remote monitoring images, which is unmatched by analog transmission. Of course, high performance returns also require high cost investment, which is one of the important reasons why pure digital security monitoring systems cannot be popularized.
4. The execution layer is the command object of our control instructions. In some cases, it is not completely separated from the support layer and the acquisition layer mentioned later. We believe that the controlled object is the weak current execution layer device.
5. As the name implies, the support layer is used to support back-end devices, protect and support acquisition layer and execution layer devices. It includes support, protective cover and other auxiliary equipment.
6. The acquisition layer is the key factor for the quality of the entire security monitoring system, and it is also the place where the system costs a lot. It includes lens video camera , alarm sensor, etc.
