Bullet Cameras vs. Dome Cameras Bullet cameras and dome cameras are the most common camera types used for home and business security today. Both are easy to install, manageable, and offer complete control to the user when securing areas of any size.
Since Olympus and Panasonic had introduced the first cameras for the Micro Four Thirds autofocus lenses there are still cameras in the market with a flange focus distance almost like that of the C-mount lenses. That was the first chance for photo amateurs to think about using C-mount cine and CCTV lenses on still cameras.
An HD analog camera is a special type of analog, or CCTV, security camera that can record surveillance video in 720p high definition (HD). While previously only a feature available on newer IP cameras, these HD analog cameras are ideal for surveillance systems that need HD quality for video evidence but may not need more the more advanced features of IP video.
Infrared Night Vision Bathes The Area in Light That’s Invisible to Our Eyes. There are a couple different types of night vision: One that most security cameras use, and one that night-vision goggles use. The most common type that’s used on most security cameras is infrared (IR) night vision, which relies on infrared light.
An IP camera is a networked digital video camera that transmits data over a Fast Ethernet link. IP cameras (also called "network cameras") are most often used for IP surveillance, a digitized and networked version of closed-circuit television (CCTV).
Few home security cameras have optical zoom lenses, but almost all have digital zoom, which crop and enlarge whatever the camera is recording. The more megapixels a camera sensor has, the more you can digitally zoom in and still be able to see things clearly.
