PTZ Dome is an integrated dome camera with features such as fast operation, optical zoom, precise positioning, and flexible control. It has been widely used in safe cities, airports, rail transit, electricity, education, industry, etc. industry. With the progress of digitalization, networking, and high-definition development of the entire surveillance industry, network PTZ cameras have also entered a new phase in product development. High-definition PTZ cameras have become a new hot spot in the surveillance industry.

High-definition megapixel cameras previously had limited chip processing performance, and they could only use the M-JPEG encoding format at megapixel resolution. As a result, users either choose megapixel resolution, accept bandwidths of 15Mbps or more, and have higher storage costs; or they can further reduce the frame rate of a megapixel camera and use it as a megapixel digital camera. So, although megapixel cameras have appeared on the market very early, the contradiction between high resolution and high bandwidth and low frame rate are the root causes that have not been popularized.

However, the above status has been completely changed in 2008. In 2008, the industry began to launch the world's first H-based. The 264-coded real-world HD network cameras have successfully solved the high-resolution, high-frame-rate, and high-bandwidth contradictions that have made network surveillance really into a practical high-definition era. As a result, domestic and foreign manufacturers began to introduce numerous high-definition fixed bolts and fixed hemispheres, as well as based on H. 264 HD Network Camera. Until now, no matter where we go, everyone is talking about high-definition, selling high-definition, and more and more users are using HD. HD network monitoring has entered the blowout era. One of the most important trends in the development of network PTZ cameras is high definition!

We have done a lot of HD camera fixed camera and SD fixed camera contrast, including resolution, image details, bandwidth, delay, etc., high-definition fixed camera has obvious advantages. If we compare a 720P HD PTZ dome with a 4CIF/D1 36X SD ball, what will happen?

At the widest angle, when the contrast is at the widest angle (at this time, the focal length is the minimum), you can see from the bottom of the figure that 36x 4CIF/D1 and 18x 720P cameras have the same horizontal viewing angle (left and right sides of the photo), but the HD speed is fast The resolution of the ball is 2 times that of the standard definition camera, and the details of the object are significantly improved.
