2024-09-18Matrix is the base of 3D maths concept. To electronical science,matrix means a construction witch has multiple input and output and any output channel can directly connect to any input channel, this is called matrix. In CCTV system, matrix is a special device by which we manage and control video image. Video switcher is the prototype of matrix and it can meet the requirement in small system. But now the market demands grows to dozens, hundreds chs or even bigger, it can’t fulfill so a new product came into being.
Now in the market basically we matrix can be divided into three categories:analog matrix,digital matrix and hybrid matrix.And according to the capacity the analog matrix could be divided into :economical type,middle type,modularity type and network type matrix.
Economical type matrix: simple menu system setting,generally applicable to small CCTV system where the output scale is less then 8 ch. Middle type matrix has a perfect menu setting system, integrates video/audio switching and manage/controlling together. It with the function of : video collection, switching, PTZ controlling,alarming, display and recording. Scale could be up to 16 chs. Modularity type matrix has the function of middle type matrix, also could be used as central platform integrating DVR , video server, to record and transmit the video/audio signals. The scale can be up to 128chs.High density modularity network matrix can be cascaded by network easily and at same time compatible with other brand of keyboard,switchers or other device. The scale could be up to 2048chs.
Digital matrix is specially designed for today’s market. It can transmit, display,switch,record video signal and integrated multiple type of video port : SDI,IP,HDMI,VGA,DVI......
VGA signal can’t be transmitted to far and usually less than 15M. So we isolate RGBHV five signal source from VGA signal in order to transmit it to further. So we can say that VGA is the same with RGB signal. DVI and HDMI is the same too and this system or matrix needs the same chs of input and output ,so both of them are adopted in broadcasting industry because it is a waste if be adopted in CCTV system. IP digital signal is transmitted by net cable. It is easy in expanding, flexible in configuration but net work will cause delay, IP signal coding and decoding will cause image quantity loss so IP system or matrix is rarely used in financial CCTV system.Hybrid matrix system is the most popular case in the market now. The market demands of analog system become lower and lower and a new product witch can compatible all input ports is needed. This kind matrix could accept BNC,DVI,HDMI,VGA,SDI and IP signal, input and output full across, can act with alarm and video/audio trail so it is suitable for security industry. In market you could find many brands of hybrid matrix but most of them are not unified in control protocol so can’t work with each other in true sense. So now,Pearmain Electronic developed S series and PE90FH HD matrix and integrated PELCO protocol, can work with and control all PELCO front end devices. Along with PE5136 communication server, our matrix can connect with or control PELCO, AD,MAX equipments.
In nowadays nearly most of the matrix are modular designed(input / output boards).This improved the stability and reliability of the product,also ensures the hardware expandability and maintainability. Suitable for middle and small CCTV systems. Take Pearmain for example,in 2011 we developed SDI HD digital matrix, adopted the most advanced high-speed high-density backboard interactive technology and high-speed signal integrity modulation technology. Along with SDI matrix, equipped with SDI HD cameras and SDI speed dome cameras, transmit the video to SDI DVR by SDI fiber optic transceivers. Or SDI video also can be decoded into digital signal and transmitted to NVR. Compared with HD IP CCTV system, SDI CCTV system has it’s advantage : no delay ,no loss of video image ,high image quality and rich color.
At present the matrix market is at maturity already and in safe city,safe campus and school ,rail transit prison ,bank projects ,matrix is become more and more popular and necessary .
