With the development of security video surveillance technology, video surveillance systems are now installed in many locations. The security monitoring system wiring design involves video monitoring lines, broadcast intercom lines, alarm lines, sound monitoring lines, and network lines. But how much do you know about monitoring wiring?
First, the integrated wiring system must be designed in advance, and cooperate with civil engineering, fire protection, air conditioning, lighting and other installation projects to avoid unnecessary construction conflicts.
2. Under the condition that the conditions permit, the weak electricity should go to its own weak electric well to reduce the chance of electromagnetic interference. The floor wiring closet and the main room should be arranged as large as possible for development and maintenance. For the network, the laying of the physical layer is crucial because it is the foundation.
Third, try to put more points, use a double-hole panel (one voice, one data), cooperate with the power, and place power points near the information points. Since the integrated wiring is generally a one-time project, the wiring is good, and it is relatively difficult to change the wiring, and the communication equipment is more and more developed, so it is more secure.
Fourth, do not make the integrated wiring too ideal, do not integrate some of the more specialized networks into the integrated wiring. It is enough to integrate the telephone network, computer network and building automation network into the integrated wiring.
5. With the rapid development of network equipment, it should be as wide as possible when selecting the scheme. The level should be five or more, to ensure that the data and voice can be interchanged, and the optical fiber is used to increase the logarithmic cable vertically. Buildings should use fiber optics for data backup rather than cables.
Sixth, due to the continuous downward adjustment of the price of optical products, the wiring between large openings should be considered to have more light spots, which is beneficial to network construction.
7. When laying the DG pipe, it is necessary to use a larger diameter, and leave a margin. Pay special attention to the turning radius when laying the optical cable. If the turning radius is too small, the link will be seriously worn out. Check each cable, especially the panel box of the optical contact. Some panel boxes are not deep enough. After the light spot is completed, the panel is not installed. When the box is on, it is not good. After the installation, the test is not good. The reason is that the corner radius of the cable is too small after installation, causing serious loss.
Eight, do not unilaterally pursue the brand of wiring products, in the past few years, in fact, some domestic manufacturers of non-shielded cables, optical cables, modules and other network equipment performance has reached the industry standards, the price has a greater advantage.
