The Development Trend Of Panoramic PTZ Camera
Oct 11, 2017

The development trend of panoramic PTZ Camera

The Panorama PTZ Camera has been developed for more than ten years, but the real promotion has only started in the last two years. Specifically, the development trend of panoramic PTZ Cameras is as follows:

1, the industry application is the main battlefield of panoramic PTZ Camera. Although the panoramic PTZ Camera is suitable for small space, easy to monitor the environment, such as retail stores, small shopping malls, elevators, car parks and conference rooms and so on. But because of the high price, the complex image processing technology and the low resolution of the image correction, the panoramic PTZ Camera has not been able to enter the public life like other ordinary PTZ Cameras. Panoramic PTZ Camera will be mainly in the financial and legal field applications, this is mainly based on these two industries special scene, need a large range of perspective coverage, use value far greater than cost pressure.

2, high resolution. At present, mainstream equipment manufacturers of panoramic PTZ Camera resolution of about 3 million, 5 million, but from the resolution density, the same pixel PTZ Cameras in the monitoring of larger areas will lead to the dispersion and degradation of pixels. This is due to the wide range of surveillance, it is necessary to receive several times image information on the same image chip with the traditional monitor lens, which causes the resolution of the screen to decrease, so it can only be used when the image quality of the monitor is not too high or the high-resolution imaging device is used. So for the panoramic PTZ Camera, improving the screen resolution is an important research topic in the future. The future Panorama PTZ Camera distinguishes at least 4K or more than 12 million pixels, which makes more sense.

3, H. 265 code. High resolution will inevitably cause the increase of bandwidth, storage pressure, the current mainstream of H. 264 encoded 4K Resolution code flow is probably in 16~32mbps, which is difficult to accept regardless of the actual network bandwidth environment or end user cost pressure. So the encoding of higher compression ratio makes the high resolution request become practical, and the key to solve this problem is H. 265 coding. According to actual test analysis, the same scene H. 265 ratio H. 264 Coding bandwidth Savings of more than half, at the same time the image processing effect also has a large degree of improvement, but also can significantly save the storage costs, so 265-encoded PTZ Cameras on the listing has received high attention and recognition. The panorama PTZ Camera will also gradually shift toward H. 265 coding, which is the market driver.

4, wide dynamic. Panoramic PTZ Camera with a 360-degree view of the fish eye lens monitoring the entire scene, such a wide range of monitoring will lead to a panoramic PTZ Camera in the white balance and exposure and other aspects of processing difficulties. Because of this, it restricts the use of panoramic PTZ Cameras indoors. The wide dynamic effect of panoramic PTZ Camera can be solved to promote the application of panoramic PTZ Camera in indoor environment.

5, Smart. Based on the industry application demand of panoramic PTZ Camera, intelligent analysis function appears especially important, and intelligent is also a general direction of security monitoring and development. The existing Network PTZ Camera intelligence analysis has the problem of low recognition rate and high false alarm rate, which need to be strengthened in the improvement of the following algorithms. In addition, the types of intelligent analysis are not limited to the virtual perimeter, Trip line alarm and other entry-level intelligence, but should be in behavior analysis, audio and video anomaly detection, traffic statistics and other aspects of the breakthrough.
