Objective Select the appropriate transmission medium for a video surveillance system design. Background Different communication channels have different characteristics and performance requirements. Based on the application environment and performance requirement (distance, bandwidth, speed, security etc.), the security professional can choose from wired or wireless transmission systems. Wired transmission systems include twisted pair, coaxial cable, and optical fiber. Wireless transmission includes RF, VHF, UHF, and infrared waves. Procedure 1. Consider that you are designing the video surveillance system for the parking lot of an apartment building in a downtown. 2. Assume that the control room with monitors is located at the second floor of the building. 3. Determine whether a wired or wireless transmission system would be better for such application. 4. Choose the specific type of transmission medium. Use the tables in the book to select the channel parameters. 4 pages .
