ABSTRACT
The digital world allows all security devices to communicate together, providing an integrated approach. Physical security applications are now Internet Protocol (IP) enabled, making the evaluation and purchase of physical security applications more complicated. Digital technology has some real advantages over the conventional tube and solid-state security systems utilized in the late 1990s. The field of digital security technology refers to closed-circuit television, card access, personnel identification, and alarm monitoring applications. Digital security technology has many distinct advantages over the old analog type utilized years ago. IP security technology utilizes fiber-optic cable to transmit security signals and data. The key to a successful installation of a digital security system is the network—ensuring that the network has the bandwidth capacity necessary to operate the devices and products purchased for the security application. The best configuration for a security network is a fiber backbone with CAT cables connecting each device.
