Development trend of intelligent high speed ball

Although the network high-speed ball machine has developed rapidly in the past two years, its application scope is still very limited due to its difficult product technology and high implementation cost. It is mainly concentrated in high input markets such as safe cities and finance.

1. Enrich product diversification and improve product performance

The network intelligent high-speed ball has also encountered many problems in the specific promotion and application process. The user's field environment is often complex and diverse, such as insufficient environmental illumination, large difference between the brightness and darkness of monitoring background light, weak technical skills of field operators, etc. These problems urgently require our manufacturers to enrich product diversification and improve product performance.

Low illumination: in some occasions where the ambient light is insufficient or the use of infrared light is strictly prohibited, due to the lack of external light, the infrared light cannot be added for night lighting, so the network intelligent high-speed ball is required to have good low illumination performance. Therefore, this kind of network intelligent high-speed ball must adopt sensors with high sensitivity and low illumination, and improve 2d/3d noise reduction technology, so as to output high-definition and noise-free images in low light;

Optical zoom multiple: seeing more clearly and further is also an urgent demand put forward by current users. At present, the network intelligent high-speed ball mostly realizes 18 times or 20 times optical zoom, and the later 28 times, 36 times and other high-power zoom must be the research and development focus of various manufacturers;

Wide dynamic: in the monitoring picture with large light contrast, the ordinary network intelligent high-speed ball can not achieve ideal monitoring. However, the network intelligent high-speed ball with wide dynamic function adopts the sensor with good wide dynamic performance and improves the back-end DSP wide dynamic processing technology. Such problems will be solved easily;

User experience: Although the network intelligent high-speed ball has various characteristic application functions, these characteristic functions require users to have sufficient knowledge and understanding of the product and certain technical skills, otherwise these characteristic functions will lose their own meaning. Simple operation and good user experience can fully reflect the advantages of the network intelligent high-speed ball.

2. High definition picture, low bit stream transmission

The most intuitive feeling that HD network intelligent high-speed ball brings to users is high definition. At present, the definition of HD network intelligent high-speed ball is mainly 720p and 1080p. It is easy to imagine that in the future monitoring application requirements, users will put forward higher requirements for clarity. For example, 3million and 5million pixel high-definition network high-speed balls need to be used in some special occasions. While improving the definition, we are also facing many technical problems. The first is the coding algorithm under high resolution. Users pay close attention to the lower code stream and lower bandwidth.

High definition picture resolution will inevitably lead to higher bit stream transmission for real-time monitoring, which undoubtedly brings high costs to network bandwidth and storage, which users do not want to see. Therefore, in the follow-up development, we should make higher requirements for video coding technology. When the resolution is improved, the code stream needs to be effectively controlled, and even the code stream with lower resolution than the current one. The latest video coding technology will also be introduced into the field of video surveillance.

3. Intelligent image analysis and standardized product access

With the widespread application of network intelligent high-speed ball, users' expectations for its intelligence will become stronger and stronger. Intelligent tracking, face recognition, perimeter intrusion, traffic statistics and other video intelligent analysis algorithms are a major trend in the development of network intelligent high-speed ball. Users hope that these intelligent analysis algorithms can be directly embedded in the front end to meet the intelligent applications in different industries and environments.

In actual engineering projects, the network intelligent high-speed ball often needs to be connected to the equipment or platforms of different manufacturers, so it is necessary for the network intelligent high-speed ball to follow the current standard protocols, such as the new national standard gb/t28181, the international onvif protocol and the third-party protocol, so as to open up a new path for the development of the network intelligent high-speed ball.
