With the popularity of domestic and international market monitoring system and a large number of applications, sd to HD switching, analog to digital transformation, simple, and upgrade to intelligent video surveillance has been rapid development in recent years, high-definition cameras have been accepted for the project in general, the current high-definition cameras mainly 960 h analog cameras, hd-sdi digital high-definition cameras, millions of HD webcam for three main line, and in the three main line, and millions of HD webcam most widely used, in this context, millions of HD network conveniently for high-speed ball, got rapid development.

IP type machine advantages and disadvantages compared

Hd high speed ball is on the market at present schools of thought contend, especially IP hd high-speed ball machine, not only the type is rich, and is the most favored by users, project traders and manufacturers Gao Qingqiu one machine. The advantages and disadvantages of this article will be to IP hd high-speed ball do a simple introduction:

IP hd high-speed ball machine's advantage lies in:

(1), IP hd high-speed ball function provides more than 720 p and hd video image, the traditional monitoring system definition more than doubled;

(2), IP hd high-speed ball machine based on network monitoring, can effectively to form a large-scale monitoring system;

(3), IP hd high-speed ball machine through a visual platform management software can be unified management;

(4), developed many IP hd high-speed ball machine manufacturers, manufacturers of technical collision is conducive to the development of products.

The disadvantage is IP hd high-speed ball machine:

(1), the network signal transmission delay, decoding delay and network exchange equipment forwarding delay problems, especially for complex network monitoring system, video preview and control delay;

(2), the network packet loss signal, encoded network signal may be because the network system problem of lost packets, the risk of loss of video data;

(3), network data transmission is not safe, especially in the public network transmission of video data are easy to be tampered with, cause the video data is stolen.

Hd development trend of high speed ball

Although network high-speed ball machine in the past two years has developed rapidly, but the technology is difficult because of its products, make the cost is high, the current application scope is limited, mainly in the safe city and financial market.

Picture high resolution, low transmission stream

Hd network intelligent high-speed ball give users the most intuitive feelings is high definition, at present the sharpness of the hd network intelligent high-speed ball is given priority to with 720 p and 1080 p. It is easy to imagine that in the future demand for monitoring applications, users will be higher requirements are put forward on the definition, such as in some special occasions need to use 3 million, 5 million - pixel hd network high-speed ball. In the definition of ascension at the same time, we are faced with many technical challenges. First is the high resolution of coding algorithm, lower stream, lower bandwidth is paying close attention to by the user. High-definition picture resolution must attract higher code streaming real-time monitoring, the network bandwidth and storage end certainly have come at a high cost, this is the user do not want to see. Therefore, the development of the follow-up, we should make a higher requirement in video coding technology, in the case of the resolution, code flow need to be effectively controlled, even be lower than the current resolution code stream, the newest video coding technology will also introduce the video monitoring field, such as the current h. 265 encoding algorithm, are many manufacturers in began to study the transition of the new algorithm.

Rich product variety, improve product performance

Network intelligent high-speed ball in the specific application process also encountered many problems, the user of the site environment is often complicated, such as inadequate illumination environment, monitoring large difference of background light brightness, technical strength weak field operation personnel, etc. These problems are urgently required us to manufacturers to rich product variety, improve product performance.

Low illumination: insufficient light or infrared light is strictly prohibited in some environment situation, because of a shortage of outside light, don't add lamp light at night, you will need to network intelligent high-speed ball has the good performance of low illumination. Therefore, this type of network intelligent high-speed ball must have a high sensitivity sensor of low illumination, and 2 d / 3 d noise reduction technology, according to low light output hd without noise image;

Wide dynamic: the difference between light monitoring screen, common network intelligent high-speed ball can't achieve ideal control, and with the function of wide dynamic network intelligent high-speed ball sensor USES a wide dynamic good performance, and improve the back-end DSP wide dynamic processing technology, this kind of problem will be solved;

Optical zoom multiples: see more clear further is the current user's urgent needs, the current network intelligent high-speed ball mostly implementation is 18 times or 20 x optical zoom, 28, 36 times in the late high ratio zoom is necessarily manufacturers develop key;

User experience: web intelligent high-speed ball, despite its various application features, these features require the user to have enough understanding and the understanding of product and technology strength, otherwise these features will lose its significance, simple operation, good user experience can fully reflect the advantages of network intelligent high-speed ball.

Image analysis of intelligent products access to standardization

With the widely application of network intelligent high-speed ball, user expectations of the intelligent will also be intensified. Intelligent tracking, face recognition, perimeter intrusion, traffic statistics, and so on intelligent video analysis algorithm is a trend in the development of the network intelligent high-speed ball, users hope these intelligent analysis algorithm directly into the front end, in order to meet the different industries, different environment intelligent application.

Network intelligent high-speed ball in the actual engineering project, tend to be connected to the equipment of different manufacturers or platform, such as NVR or CMS management platform, etc., to be compatible with different manufacturers, different brands of NVR and management platform, you need to network intelligent high-speed ball to follow the current standard protocols, such as the new national standard GB/T28181, international Onvif protocol, and the third party, this will open up a new path for the development of the network intelligent high-speed ball.
