Advantages of Security Industrial Switches

City security consists of two parts: air defense and video security monitoring. The main function of the video surveillance system is to assist the civil air defense system to monitor the live scene of the city. It enables managers to observe all the conditions of the video surveillance site in the center, provides monitoring means for various equipment operations and personnel activities, and is the most important part of the entire security system. A high-definition network camera is installed at the front of the system, which is transmitted to the monitoring center through the internal network. The system mainly uses the latest computer processing technology to encode and compress the video and audio signals of the front-end high-definition network monitoring points into digital signals, and transmit them to the monitoring center through the network. The monitoring center is responsible for management, storage, retrieval, alarm linkage and other functions.

Large-scale security network monitoring systems have very strict requirements for network transmission and signal conversion, and it is difficult for general commercial switches to meet the real-time, integrity and smooth transmission requirements of large-traffic network video signals for security monitoring. In the application of security system, it is best to use professional Industrial Switches to meet the complex and changeable application environment.

Security industrial switches are a special type of switches. In recent years, due to the rapid popularization and application of the monitoring industry, security industrial switches have begun to spread rapidly in the security field, and the number of use has increased sharply, providing a strong source for the development of the security industry. So, what are the characteristics of security industrial switches?

1. Due to the unique characteristics of the security system, most of the front-end cameras are installed in an outdoor environment. As a switch device for video transmission, it must be able to withstand a wide range of temperature changes, humidity changes, lightning shocks, electromagnetic disturbances, etc. This kind of bad factor, so the security industrial switch has become a necessary choice. It is generally made of aluminum alloy, high-strength shell, fully enclosed, with a high level of dustproof, waterproof and corrosion resistance. The power supply is generally a low-power design, and dual power supply redundancy is used. The internal motherboards, chips and other hardware configurations are industrial-grade solutions, which can effectively resist static electricity, lightning strikes and other interference, shock resistance, vibration resistance, and can work safely and stably for 100,000 hours in the environment of -40℃~85℃ above.

2. Rich network and security features: support VLAN, STP/RSTP, multicast, port mirroring, QoS, port security and other network protocols, support ring, star, tree, hybrid and other network topologies, fast ring Network self-healing ability≤50ms.

3. Convenient management function: It supports various management methods such as SNMP, WEB and CLI, supports centralized management of the platform, and realizes efficient centralized management in unattended environment and large-scale discrete deployment. Therefore, network administrators can monitor the working status and network movement of switches locally or remotely in real time, and manage the working status and working modes of all switch ports on a global scale.

4. The security industrial switch supports two-way redundant power supply design, 4-pin pluggable terminals, supports 12~48V wide voltage input, AC and DC universal, and provides power supply anti-reverse connection protection and over-voltage and under-voltage protection, which greatly improves the product's stability of work; in line with industrial-grade standardized design requirements, generally reaching IP30 protection level or above, with super waterproof, dust-proof and anti-corrosion capabilities;

Ordinary switches have low data exchange efficiency, low video data forwarding efficiency, and network storms, which may easily cause the risk of frame loss; the circuit design adopts a single-board layout, which makes the product work unsafe; the design transmission distance of general switches can only be 80 meters -100 meters range. The cost-effective security industrial switch, but the price is similar to the ordinary network switch, which can better meet the various needs of security monitoring.

Industrial switches are not only communication network equipment and industrial interconnection equipment, but also a happy messenger, helping you to automatically check online systems and accurately locate faults online, giving you peace of mind, saving you worry, time and money. We focuses on professional fields such as Ethernet communication, industrial fieldbus transmission, industrial optical fiber access, and industrial switches. The main products have independent intellectual rights, and have obtained CE, FCC, ROHS, IEC61850 and other international certifications and power industry EMC electromagnetic compatibility and other industry standard certification, and through the technical testing and certification organized by many domestic professional organizations, to meet the requirements of various industry standards such as urban security, smart grid, coal mine safety, rail transit and so on.
