Publisher Summary This chapter provides design guidelines and hardware information, specific case studies, and a checklist for representative security applications. It analyzes specific applications and hardware, specifications, and questions to be asked and answered for several specific scenarios. Applications covered in the chapter apply to facilities occupied by governmental agencies, manufacturers, industrial companies, and retail and commercial business services. The video surveillance applications include lobbies, elevators, offices, rear doors, shipping areas, hallways, cashier checkout areas, and warehouses. Temporary and permanent covert video systems are used in installations for viewing the general public entering a facility as well as for monitoring employees. Wide field of view (FOV) optics and zoom lenses are used for parking lots and perimeter-fenceline environments. The video systems described in the chapter are indoor and outdoor, analog or digital, and single site, multiple sites, and remote site. The rapid deployment application includes a wireless alarm-intrusion system. In view of this large installed base of analog equipment, many new installations will still be performed using new analog equipment.
