There are two types of dome cameras available, fixed and PTZ (pan, tilt, zoom). A fixed dome camera shoots a constant position, while a PTZ is more versatile with the ability to shoot from various angles and can be programmed to zoom at the cue of desired motions. Many businesses prefer dome cameras as a security measure because of their weatherproof and vandal-proof design. Another advantage is the smoked covered bubble that encases the camera. This allows the camera to be obscured from people’s vision, making it harder to know whether they are on surveillance. Dome cameras are a perfect way to maximize security within an establishment. Although, some drawbacks would be the intrusive bubble design, and the limitation of where to install the cameras. Most are ideally made for ceiling use, possibly making maintenance a task.
