Analysis of the advantages and disadvantages of IP HD and HD-SDI HD Speed ​​Dome

A highly integrated product that integrates a pan/tilt system, a communication system, and a camera system. The pan/tilt system is a rotating part driven by a motor. The communication system controls the motor and processes the image and signal. The system refers to the one machine movement adopted. And between the major systems, the horizontal connection is a master core cpu and power section. The power supply part is powered by the main system, and many places use micro-current power supply such as diodes and triodes, and the core cpu is the basis for realizing all functions. It is a highly integrated product that integrates a PTZ system, a communication system, and a camera system. The PTZ system is a rotating part driven by a motor. The communication system controls the motor and processes the image and signal. The camera system refers to the integrated machine movement. And between the major systems, the horizontal connection is a master core cpu and power section. The power supply part is powered by the main system, and many places use micro-current power supply such as diodes and triodes, and the core cpu is the basis for realizing all functions. 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.

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.

Analysis of the advantages and disadvantages of IP HD and HD-SDI HD Speed ​​Dome

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.

Multi Layer PCB

Multi-Layer Circuit boards. In order to increase the area that can be wired, the multilayer board uses more single or double-sided wiring boards. Using a double-sided inner layer and two single-sided outer layers, the printed circuit board which is alternately arranged by the positioning system and the insulating bonding material and the conductive pattern is interconnected according to design requirements becomes four layers, similiar stack up for 6 layer, 8 layers etc. The layers are more than two called multiple layers printed circuit board. The number of layers of the board does not mean that there are several layers of independent wiring layers. In special cases, empty layers are added to control the thickness of the board. Usually the number of layers is even and the outermost two layers are included.
