HD-CVI is a new camera technology that allows 720P or 1080P video signals to be transmitted over solid copper conductor coaxial RG-59U cable or better. The HD-CVI cameras and DVR recorders are also inexpensive when compared to IP cameras. For customers with existing CCTV systems, chances are they are using coaxial cable already and upgrading to a HD-CVI system for high definition video makes more sense as it saves tremendous costs of re-running wiring and equipment cost is also lower. For customer looking for new HD camera systems, HD-CVI is a great lower cost alternative to IP network cameras, and is also simpler to install as it is plug & play and requires no network configuration for each camera as in the case of IP, which is a common hurdle for many users who are not familiar with networking.
