At present, the high-definition high-speed ball on the market can be said to be a hundred schools of thought, especially the IP high-definition high-speed dome, not only a variety of types, but also one of the most popular HD domes for users, engineers and manufacturers. This article refers to the address: http:// Advantages and disadvantages of IP HD Speed ​​Dome The advantages of IP high-speed high-speed dome camera are as follows: 1. The IP high-definition high-speed dome camera can provide high-definition video images of 720P and above, which is more than double the resolution of the traditional monitoring system. Second, the IP high-speed dome camera is based on networked monitoring and can effectively The establishment of a large-scale monitoring system; Third, the IP high-definition high-speed ball machine can be managed through the visual platform management software; Fourth, the development of IP high-speed high-speed ball machine manufacturers, the technical collision of various manufacturers is conducive to product development. The shortcomings of IP high-speed high-speed domes are: First, network signal transmission delay, there are codec delays and network switching equipment forwarding delay problems, especially for complex network monitoring systems, video preview and control delay is large; Second, network signal loss The encoded network signal may lose data packets due to network system problems, and there is a risk of losing video data. Third, network signal transmission data is not secure, especially in the public network, video data is easily falsified, resulting in video data being stolen. HD-SDI high-definition high-speed ball advantages and disadvantages The advantages of HD-SDI high-definition high-speed dome machine are as follows: 1. It can be based on coaxial cable transmission. For many analog monitoring systems that have been built, it can use existing lines to complete high-definition transformation, and maximize cost savings for users; The operation is similar to the traditional CCTV system. Different from the IP system, the management and maintenance personnel need certain IT application skills. This has no cost for re-learning for the traditional CCTV security practitioners. 3. HD-SDI transmits uncompressed HD signals. The image restoration effect is more realistic than the IP high-definition high-speed dome camera. The video delay and control delay are smaller than the IP high-definition high-speed dome camera. This is also a key factor for many users to choose HD-SDI high-definition high-speed dome. The shortcomings of the HD-SDI high-definition high-speed dome machine are as follows: 1. The HD-SDI signal is currently transmitted at the farthest distance of 100 meters, and the cost of long-distance transmission is high. Second, if the HD-SDI equipment is to be built into a large-scale monitoring system, it is the same scale. The IP surveillance system is much more expensive. From the current application of IP/HD-SDI high-speed high-speed ball, the IP high-speed high-speed dome machine market accounts for a relatively high proportion. Comprehensive multi-faceted data analysis, the main factors for users to choose IP high-speed high-speed dome machine are: First, IP high-speed high-speed ball machine is lower than HD-SDI ball machine; Second, IP high-speed high-speed ball machine has video capture and encoding function The data can be directly stored. The HD-SDI dome only performs video capture, and requires encoder compression before recording, which increases the cost of the encoding device. Therefore, for routine monitoring projects, cost control often determines the final choice of IP high-speed dome. The HD-SDI dome has a certain market share. The users who choose HD-SDI are generally industrial users, mainly considering the advantages of HD-SDI high-speed dome camera in image restoration and real-time.
