For one, a perimeter security fence is designed to optimize your overall commercial security measures, including securing your premise and protecting your property and building occupants of threats.
Nowadays, fiber cable are widely used and gradually replaced the copper cable in the video security & surveillance systems. With the benefits of fiber cabling, many limitations are solved. The benefits of fiber cabling as the following:
1. Immunity to Electromagnetic Interference
Magnetic field lines generate an electrical current as they cut across conductors. The flow of electrons in a conductor generates a magnetic field that changes with the current flow. Electromagnetic Interference does occur in coaxial cables, since current does cut across the conductor. Fiber optics are immune to this EMI since signals are transmitted as light instead of current. Thus, they can carry signals through places where EMI would block transmission.
Fiber optic cable is one of the fastest-growing transmission mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Fiber offers a number of advantages over copper.
