What is SDI?

The SDI interface is a "digital component serial interface" while HD-SDI interface is a broadcast level high-definition digital input and output port, where HD represents high-definition signal. Because the SDI interface can not directly transmit the compressed digital signal, after the compression signal reproduced by the digital recorder, hard disk and other equipment is replayed, it must be decompressed and output through the SDI interface to enter the SDI system. If decompression and compression are repeated, the quality of image will decrease and delay will increase. Therefore, different formats of digital video recorder and non-linear editing system have their own interfaces for direct transmission of compressed digital signals.

In the late non radio field, HD-SDI is widely used, which is based on SMPTE292M interface specification of transmission in the signal rate under the conditions of 1.485Gb/s or 1.485/1.001Gb/s. The specification includes data format, channel coding, signal specification of coaxial cable interface, connector and cable type and fiber interface. The HD-SDI interface uses a coaxial cable, and the BNC interface is used as the cable standard. The effective distance is 100M.

Monitoring System


1, According to the rate:

Standard definition SD-SDI (270Mb/s),

high definition standard HD-SDI (1.485Gb/s) and

3G-SDI (2.97Gb/s)


2, HD-SDI interface corresponding with HD HD-SDI monitoring system of HD-SDI camera, HD-SDI transmitter and HD-SDI to HDMI converter, HD-SDI hard disk video recorder, HD-SDI matrix, the formation of large screen.



3, HD-SDI monitoring system advantages:

Because the device is connected by BNC interface, that is to say, in the process of transforming the existing traditional simulation frame system into HD monitoring system, there is no need to rewire, just replace the front end and the back end part, which will save huge time and labor cost for the project.

Ease of use

Because the system frame and simulation monitoring system framework of HD-SDI camera product construction are the same, the 75-5 coaxial cable can be used to achieve system wiring, and the construction staff and system operators need no training, so it is easier to get started.


HD-SDI camera is not like IP monitoring, which compresses and packages video signals through the network. It transfers with uncompressed digital signals on coaxial cable at high speed, and the original image is not distorted.

High definition real time

HD-SDI camera monitoring is not affected by the transmission network, and there will be no image delay caused by IP network monitoring. It is in the situation of real-time monitoring and high definition.

High utilization rate

The resolution of the video output image of the HD-SDI camera is 1920 x 1080, and the density of the point of the unit area is greatly reduced. Provide more details on the monitoring site, such as seeing the face, and seeing the license plate.
