Development Trend Of PTZ Camera

  Development Trend of PTZ Camera

  PTZ camera development has been more than a decade, and the real promotion is from the past two years began. Specifically, the development trend of PTZ camera is as follows:

  1, the industry application is the main battlefield of the PTZ camera. Although the PTZ camera is suitable for use in small spaces, where the environment is simple, such as retail stores, small shopping malls, elevators, parking lots and conference rooms. But because of its high price, complex image processing technology and image correction after the low resolution and other factors, PTZ camera did not like other ordinary cameras into the public life. PTZ cameras will be mainly used in the field of finance and politics, which is mainly based on the special scenes of these two industries, the need for a wide range of perspective coverage, the use of value is much greater than the cost pressure.

  2, high resolution. The current mainstream equipment manufacturers PTZ camera resolution of about 3 million, 5 million or so, but from the resolution density considerations, the same pixel camera in monitoring a larger area will lead to pixel dispersion and degradation. This is due to the large range of monitoring, in the same size with the traditional surveillance lens share the same imaging chip, you need to receive several times the image information, which caused the picture resolution decreased, so only in the monitoring image quality requirements are not too High or high-resolution imaging devices can be used. So for the PTZ camera, improve the screen resolution is an important future research topic. The future PTZ camera resolution at least 4K or even 12 million pixels or more, so that more meaningful.

  3, H.265 encoding. High resolution will inevitably lead to bandwidth, storage pressure increases, the current mainstream H.264 encoding 4K resolution bit stream in about 16 ~ 32Mbps, regardless of the actual domestic network bandwidth environment or end-user cost pressures are hard to accept. So the higher compression ratio of the encoding method makes high-resolution demands become practical, and solve the problem is the key to H.265 coding. According to the actual test analysis, the same scenario H.265 than H.264 coding bandwidth to save more than half, at the same time the image processing effect is also greatly improved, but also significant savings in storage costs, so the 265-encoded camera will be listed Very high attention and recognition. PTZ camera will also gradually shift towards H.265 encoding, which is the market driver.

  4, wide dynamic. The PTZ camera uses a fisheye lens with a 360 degree oversized view to monitor the entire scene. Such a wide range of monitoring is bound to cause the PTZ camera to be difficult to handle in terms of white balance and exposure. It is precisely because of this, limiting the PTZ camera in the indoor application. Solve the wide dynamic effect of PTZ camera, can promote the future PTZ camera in the indoor environment applications.

  5, intelligent. PTZ camera based on the strong application of industry demand, intelligent analysis is particularly important, intelligent development is also a major direction of security monitoring. The existing network camera intelligent analysis of the existence of low recognition rate, the high rate of false positives, which is in the follow-up algorithm to improve the need to strengthen. In addition, the types of intelligent analysis are not limited to virtual gate, trip line alarm and other entry-level intelligence, but should be in the behavior analysis, audio and video anomalies detection, traffic statistics and other aspects of a breakthrough.
