Home Security Systems

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:

• Low upgrade costs. Cameras can connect to existing analog coax cables, eliminating the need for new wiring.
• Simple installation and setup. Most products in this category are designed for near plug-and-play operation.
• No interference with networks. These systems can be operated in complete isolation from the data network if desired.
• Support for 1080p high definition cameras.

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).

• PTZ cameras have an adjustable field of view, meaning they can capture large areas and also quickly zoom in to capture fine details in a scene, such as a face or a license plate. These cameras can move in all directions and they are ideal as business security products and home security products. Camera systems provide the best evidence.
