Sichuan Security Company: As for the security monitoring system, according to the different functions of each part of the system, it is divided into seven levels. Let's get to know it one by one.
1. Embodiment layer
Embodiment layer is our most intuitive feeling, it shows the quality of the whole security monitoring system. Such as monitoring TV wall, monitor, high-pitch alarm horn, alarm automatic connection telephone and so on all belong to this layer.
2. Control Layer
The control layer is the center of the whole security monitoring system, and it is the clearest embodiment of the system's scientific and technological level. Sichuan Security Company said that there are two kinds of common control methods - imitation control and digital control. Simulated control is a pre-operation method. Its console is generally composed of a controller or a simulation control matrix. It is suitable for small part of security monitoring system. This control method has low cost and low failure rate.
3. Treatment Layer
Processing layer may be called audio and video processing layer. It distributes, enlarges, cuts and so on the audio and video signals sent from the transmission layer. Organically, it connects the embodiment layer with the control layer. Audio and video distributors, audio and video enlargers, video cutters, audio and video switchers and so on all belong to this layer.
4. Transport Layer
Sichuan Security Company said that the transmission layer is the blood of security monitoring system. In the small security monitoring system, the most common transmission layer devices are video and audio lines.
5. Implementation Layer
The performance level is the command target of our control instructions. At some times, it is not entirely separated from the support level and the collection level we are talking about later. We think that the controlled target is the performance level equipment. For example: Cloud platform, lens, decoder, ball, etc.
6. Supporting Layer
The support layer is used to support the back-end equipment, maintain and support the collection layer and performance layer equipment. Including support, protective shield and other auxiliary equipment.
7. Collection layer
Collection layer is the key factor for the quality of the whole security monitoring system, and it is also the place where the cost of the system is the largest. It includes lens, camera, alarm sensor, etc.
