There is a recent surge of Analog HD CCTV Systems and Cameras. The most common formats are AHD, HD-CVI, HD-SDI and HD-TVI.

Why is this happening and what are the pros and cons of HD analog system?

There was a demand for a high-quality Analog Systems for a very long time. Consumers wanted to buy HD quality systems for the least amount of money.

AHD systems and cameras are very low-priced and are better than Analog.

HD CVI has low price and decent quality; they come in 720P and 1080P.

HD-SDI am not low price but has very high quality. They also come in 720P and 1080P. You might have to use a repeater if the distance between the camera and the DVR is over 300 feet. Installers are advised to use very high-quality coaxial cable. Do not use baluns with HD-SDI cameras.

HDTVI have low price and very good quality picture. They come in 720P and 1080P. Repeaters are not required for cable runs over 300 feet.

There are no losers or winner yet. HDTVI is my favorite and is poised to be the winner in the in the HD Analog category.
