These systems, which are composed of a video camera, a PC, software, and a printer, have several advantages over film-based cameras. Because employee data is stored in the computer, lost cards can be replaced without requiring employees to leave their workstations to take another photograph. The systems can also save per card costs because the employee's photograph can be previewed on the computer screen before the card is printed. In addition, cards can be easily color-coded for different security levels. Video imaging can be costly, however.
Several factors affect the price of a video imaging system.
Color cameras, for example, are more expensive than black and white. Some systems stand alone, while others can be networked into computers located at guard desks, allowing the security officer to access the employee database and check the image of anyone who claims to have forgotten his or her ID badge at home. More sophisticated systems allow the security manager to track the number of cards issued to each individual. The key to any video imaging system is its flexibility. Specifically, the security manager should consider a system that can both network with the databases of other company departments and support different types of printers.
