The homeowner or businessperson must first determine what areas need coverage. In a home, the coverage space may consist of a door, windows or driveway. Businesses may require coverage of a door, cash register, and storage room or product aisles.

One of the most popular security cameras for businesses is the Dome PTZ (pan/ tilt/zoom) camera. The 360-degree flexibility and capacity to zoom in on objects or faces make this camera very popular for keeping tabs on parking lots, building parameters, large warehouses and other spaces. Bullet security cameras, so named because of their bullet-shaped housing, are popular for surveillance of exterior surroundings.
