Difference Between The Security Dedicated Industrial Switch and Common Switch

The dedicated Industrial Switch for security is a network transmission equipment developed for the actual needs of high-definition monitoring of security networks. It has the functions of routers, firewalls, managemed switches and other network transmission and network management equipment. Compared with ordinary switches, the dedicated industrial switch for security has enhanced its functions on the basis of ordinary switches, and its port configuration and product series are more abundant and flexible, which can meet the needs of various security fields.

Because of the unique characteristics of the security system, the installation environment of the front end camera is all outdoor. As a video transmission switch product, it should also be able to withstand a wide range of temperature fluctuations, humidity changes, lightning shocks, electromagnetic interference and other adverse factors, so the industrial switch has become a necessary choice. The industrial switch adopts industrial grade chips, which can adapt to the working environment of - 40 ℃ - 85 ℃. The power supply adopts redundant design, and can pass strict vibration and impact tests. Because of these characteristics, the security industrial switch will become the main transmission equipment of the security monitoring system.

When the network technology is introduced into the network monitoring system, the front-end webcam and back-end NVR are well adapted to the needs of the security monitoring industry. In order to overcome the electromagnetic compatibility and temperature environment problems that may be encountered, some engineers directly use the security dedicated industrial switch. So, what's the difference between the security dedicated industrial switch and the common switch?

Difference between the security dedicated industrial switch and the common switch?

The security dedicated industrial switch itself is not fundamentally different from the ordinary switch in terms of data link layer, network layer, protocol layer, etc., but in view of the real-time requirements of industrial control, the security dedicated industrial switch solves the technical problems of real-time communication, network security, intrinsic security, etc., and adopts some measures suitable for the industrial environment, such as waterproof, anti vibration, etc.

The dedicated security monitoring switch supports two-way redundant power supply design, pluggable terminals, 12~48V wide voltage input, AC and DC universal, and also provides power anti reverse connection protection, overvoltage and undervoltage protection, greatly improving the stability of the product; Comply with the industrial standard design requirements, the shell is made of metal shell, reaching IP30 protection level or above, and has strong waterproof, dust-proof and anti-corrosion capability- The operating temperature is 40 ℃～ 75 ℃, and the storage temperature is - 40 ～ 85 ℃. It can also operate safely under extreme weather conditions.

Common switches have low data exchange efficiency, low video data forwarding efficiency, and there is a network storm, causing the risk of frame loss; The circuit design adopts single board layout, making the product work insecure; The design transmission distance of general switches can only be within the range of 80 meters to 100 meters.

The price of the cost-effective security dedicated industrial switch is similar to that of the ordinary network switch, which can better meet the needs of security monitoring. The application environment of network monitoring engineering is often complex and changeable. It is difficult for ordinary switches to meet the real-time, integrity and smoothness transmission requirements of security monitoring large flow network video signals. Therefore, the dedicated industrial switch for security has a good place in the security monitoring system.

At present, the traditional big brands of the dedicated industrial switches for security are basically foreign brands. After years of development, domestic brands have gradually emerged. The main advantage of domestic brands is high cost performance. This is just in line with the market demand of the security industry. With the increasing demand for industrial switches in the security industry, the domestic manufacturers of dedicated industrial switches for security are also growing rapidly. Therefore, as the industry technology of industrial switches becomes more mature, domestic brand industrial switches will soon become the mainstream of transmission products in the security industry.
