core of the security monitoring system

The performance of the city is our most intuitive feel, it shows the quality of the security monitoring system. Such as surveillance video wall, URL=http://www.ipcctvcamera.net]ip camera[/URL] surveillance camera wireless ip camera monitors, treble alarm horn, alarm and automatic SPIDERS phone, etc. belong to this level. Control layer Control layer is the core of the security monitoring system, it is the system most clearly reflected the technological level. There are usually two of our control - analog control and digital control. Analog control is early control, its console is usually controlled by the controller or analog matrix for small local security monitoring system, this control method is low cost, the failure rate is small. But for the purposes of large-scale security monitoring systems, this approach becomes complicated to operate and no price advantage, then we should be more informed choices digital control. Digital control is to control industrial computer as the core monitoring system, it becomes network camera ip camera systemcomplex analog control operation simple mouse clicks, the huge stack reduced to an analog controller industrial computer, the huge number of complex and variable control cables as a serial telephone line. It will become a reality in the remote monitoring provides remote monitoring possible for the Internet. However, digital control is not so perfect, the price is very expensive control panels, waste modules, the system may appear crumble crisis control lags behind so the problem persists. Processing layer Perhaps the processing layer is called audio and video processing layer, transport layer will have audio and video signals sent over to distribution, amplification, processing division, etc., will be connected to the performance of the organic layer and control layer. Audio and video distributor, audio and video amplifiers, 16ch NVR Recorder security systems splitter, audio and video equipment switches, etc. belong to this level. Transport Layer Transport layer security monitoring system is equivalent to the blood. In a small security monitoring system, our most common transport layer device is a video cable, audio cable, For remote monitoring system, we often use the RF line, microwave, for remote monitoring, we usually use the Internet 4ch NVR Recorder this a low-cost carrier. It is worth mentioning that the media transport layer emerging - cable / fiber. Most people there is a misunderstanding in the digital security monitoring, they think digital control layer security monitoring system is used to control digital security monitoring system, and it is not. Pure digital transmission medium security monitoring system must be cable or optical fiber. When signals from the acquisition layer out, it has been modulated into a digital signal, and digital signal surveillance system run on a network has matured, theoretically without attenuation, which guarantees no loss of image displaynetwork camera surveillance system remote monitoring, which is unmatched by analog transmission the. Of course, high returns also require costly investment, which is not pure digital security monitoring system, one of the most important reasons for the popularity. |
