Q:Intelligent security and smart home profit space which big?
Security monitoring system components - security monitoring system is a growing attention of new professionals, the current development of view, the application of more and more popular, scientific and technological content is getting higher and higher. Almost all high and new technology can promote its development, especially the advent of the information age, but also to provide an opportunity for the development of the profession. But as far as the monitoring industry is concerned, the system composition has not been clearly divided, which makes communication between the engineering company and the user talking about the security monitoring system very inconvenient.
Q:How does the security monitoring system go through the line?
Bright dark line details: bridge design is reasonable, to ensure the appropriate cable bending radius. When the upper and lower sides are around the other line grooves, the slope of the turn should be gentle, and the key point is that the cable at both ends will sag. After the force is applied, the cover plate can also be laid on the premise that the cable is not damaged.On line process is mainly control the tension, the tape reel cable, at least two suggestions to arrange for a worker to scroll in Guyed pole homemade, line end workers first pulled out a part of the cable from the scroll box for the pipeline in the pre, the other end of pre extraction.
