High-end Conference Camera SDI Interface Transmission Advantages And Disadvantages

High-end conference camera SDI interface transmission advantages and disadvantages

The video conference camera is mainly composed of several components such as the movement, the head, the hardware circuit, and the structure.

The IP/HD SDI conference cameras use high-definition digital movements to complete the image acquisition and use the same pan/tilt drive mechanism to complete control and have the same structure. Tenveo video through long-term experiment shows that the biggest difference between the two lies in the hardware circuit, IP high-definition video conference camera will capture the high-definition signal encoding movement after compression, the output IP data packets transmitted through Ethernet; HD SDI video conference camera movement After the collected high-definition signals are format-encapsulated, the output uncompressed raw data is transmitted through an HD SDI cable.

Therefore, from the aspect of product technology, the difference between the two is that the hardware circuit is different. Relatively speaking, the technical bottleneck of both is the function of the movement. For example, how to obtain better image restoration effects, how to obtain better results in low illumination, and how to enhance the clarity of images are common challenges that need to be overcome in the development of IP/HD SDI high-speed domes.

The advantages of HD SDI output are:

    1, can be based on coaxial cable transmission, for many screens have input ports, can use existing lines to complete high-definition transformation, to maximize user cost savings;

    2. The product operation is similar to the traditional CCTV system. Different from the IP system, the management and maintenance personnel have certain IT application skills. This has no re-learning cost for the traditional employees.

    3, HD SDI transmission of non-compressed high-definition signal, the image reduction effect is more real than IP high-speed dome camera, video delay is smaller than the IP high-speed dome camera, which is a key factor for many users to choose HD SDI video conference camera.

The disadvantages of HD SDI output are:

    1. High-definition SDI signal is transmitted 100 meters farthest at present, if you want to carry out long-distance transmission cost is higher;

    2. If a high-definition SDI device is to form a large-scale video conference system, the cost of an IP video conference system of the same size is much higher.
