Difference between digital matrix and analog matrix

2015/3/10 Read (7631)

Contrast parameter

VGA digital matrix

Digital matrix of general decoding card

Simulation matrix

Video / audio input

It can be either an analog signal input or a digital signal input. DVR DVS、IP CAMER 等数字信号输入。 It can directly input the analog signal of the front camera, and it can also input digital signals such as DVR , DVS, IP CAMER . The audio and video of the digital system come in pairs, without the need for separate audio functions.

Can only be analog signal input

Video storage function

It can flexibly adopt centralized or distributed storage according to the network structure, and it can also adopt a multi-level storage structure.

Historical video playback

It can be played back to the TV wall remotely, and the operation is very convenient.

Cannot support playback to TV wall monitor

Video / audio output

高清 输出实现 VGA/DVI/HDMI等接口输出 Digital signal output on the TV wall, high-definition output to achieve VGA / DVI / HDMI and other interface output . Video and audio synchronous output, no additional audio module is required. Each output supports at least 1280 * 1024 respectively rate output, and supports large screen to display multiple high-definition videos at the same time.

BNC 输出。 Can only be analog BNC output. Video and audio synchronous output, no additional audio module is required. Zui Gao only supports D1 (704 * 576) output. HD output is not supported.

It can only be an analog signal BNC output. An audio module is required for audio output.

Local video switching output

Group switch, synchronous switch, program switch setting and instruction execution, switch forward and backward; remote high-speed dome and PTZ control functions. Fully realize all the switching functions of the simulation matrix, and have made many optimizations for manual or automatic switching functions, such as mobile video frame detection and alarm linkage switching functions.

Unlimited

Unlimited

16 组群组切换、各群组支持 32 个同步切换,各同步支持 32 个单切换。 Generally, only 16 groups of group switching are supported , each group supports 32 simultaneous switching, and each synchronization supports 32 single switching. 16 组程序切换,各程序切换支持 32 个单切换。 Support 16 groups of program switching, each program switching supports 32 single switching. Alarm linkage only supports one-to-one linkage switching.

Remote switching output

Various switching functions such as group switching, synchronous switching, and program switching can be performed remotely. 多点分布 电视墙切换所有全网路中的多级或多个监控中心的多路视频,数量无限制,并同时进行高速球等控制。 Support multi-point distributed TV wall to switch all channels of multi-level or multi-monitoring video in the entire network. The number is unlimited, and high-speed ball and other controls are performed simultaneously.

RJ45 矩阵键盘,无法远程操作执行主控与副控权限,副控数量受限。 The main control and sub control are restricted by the RJ45 matrix keyboard. The remote control cannot execute the main control and sub control permissions, and the number of sub control is limited.

Screen division function

-64 多画 面分割 显示 ,支持焦点画面显示,支持多台监视器同时多画面分割。 Multi-screen split display such as 1-64 , support focus screen display, support multiple monitors and multi-screen split at the same time. Support multi-screen segmentation during playback.

面分割 显示 ,不能支持焦点画面显示,4画面分割显示只能是CIF图像分别率。 It only supports 1/4 screen split display , but cannot support focus screen display. 4-screen split display can only be CIF image resolution. Does not support playback on TV wall monitors.

Without this function, an external screen divider is required to achieve screen division display.

HD image support

Support 720P / 1080P HD image decoding output

Does not support HD, high D1 , and only single screen

Not supported, only analog signals

Alarm electronic map

Support alarm electronic map, and display to TV wall monitor, call up video picture through electronic map

Character overlay function

The system comes with characters such as system time, date, running status, and camera title screen display. No character overlay required.

The system comes with characters such as system time, date, running status, and camera title screen display. No character overlay required.

Supports system time, date, running status, camera title screen display, but requires a character overlay.

System compatible

Can be compatible with multi-vendor equipment and multiple resolution images

Generally only support specific manufacturers' equipment and one resolution (D1 or below) decoding output

not support

price

When the number of video channels is small, it is slightly higher than the analog matrix

Higher prices than the simulation matrix

Low price
