WHAT IS IP, CVI AND TVI HD

IP HD CAMERAS?


An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet.

IP Cameras are the most commonly used Cameras in the Electronic Security Industry today, they are reliable and practical interms of installation and all round functionality.Even more interesting is that they are becoming extremely affordable.


HD-CVI (High Definition Composite Video Interface)


In 2012, Dahua announced that they were in the process of developing their own HD CCTV standard and as a result, HD-CVI was born. So what is HD-CVI?

HD-CVI Is a very powerfull technology that allows the end user to easily upgrade their old analogue system to an HD system without spending additional money, imagine the possibilties, thier are billions of old anologue systems in the world, all waiing to be upgraded to HD qaulity at affordable pricing.

HD-CVI is for high definition analogue solutions with megapixel resolution and zero latency over longer distance video transmissions. According to Dahua, the name has to do with its baseband and quadrature amplitude modulation technology, which is able to avoid CVBS cross talk and separate the brightness and hue signals that further enhance the video quality. Their technology allows an extremely low signal distortion over long distance transmission with its patented Auto Signal Compensation (ASC) feature.

In short, the positive side is high quality megapixel images in both 720p and 1080p formats. The negative is that it is not compatible with other HD offerings.


HD-TVI (High Definition Transport Interface)

This also began development in 2012 through Techpoint and finally being acquired by Hikvision and a few other Chinese manufacturers for their offering in the HD CCTV market. HD-TVI also based on distance transmission using coax cabling, it converts digital signals to analogue ones and offering both 1080p and 720p resolutions. HD-TVI also offers zero latency allowing for real-time preview without delays. HD-TVI, due to its open source framework, is able to work with other manufacturers and therefore not restricted to one brand.

In short, the positive is its compatibility to work with other manufacturers and its affordable pricing, similar to 960H.
