CCTV systems use many different types of security cameras, depending on security needs.
DIGITAL SECURITY CAMERAS (HD) OVER COAX
CCTV systems are security products used by businesses to protect their interests. HD over Coax refers to the transmission of high-definition video and audio streams over coaxial cables that were previously limited to a standard quality video.
There are several competing technologies in this category, including CVI, TVI, SDI, and others. They vary somewhat in capability, but in general, the major benefits over an IP video system include:
HD over Coax is ideal for companies that have an existing analog infrastructure in place, would like to reduce the overall cost and are looking to upgrade their cameras to 1080p. It is also great for new installations if your budget is extremely limited.
ZOOM (PTZ) SECURITY CAMERAS
A Pan-Tilt-Zoom (PTZ) camera is a specialized security camera that can change direction and zoom in and out based on commands given from a DVR. Some DVRs support remote control for PTZ cameras over the Internet using a mobile device or computer, allowing you to control the camera’s movement from anywhere in the world.
PTZ cameras can be used to cover much larger areas than stationary cameras with a full range of horizontal and vertical movement (pan and tilt respectively).
