Compare HD Analog Technologies

See how the different formats stack up…

HD Analog technology offers a compelling alternative to traditional analog and IP surveillance options. HD Analog video security solutions deliver megapixel resolution video over coaxial cabling (HD over coax), and are far less complex to install and operate compared to IP.

 

Since its introduction, several HD Analog formats have emerged, including: HD-SDI, AHD, HD-CVI and HD-TVI. While all HD Analog options offer the same basic benefits compared to analog or IP, each format features a unique set of capabilities and compatibilities.

At this time, there is no “standard” format – or established “winner” – in the HD Analog space. But, it is clear that certain formats are better positioned to succeed – offering clear competitive advantages that translate to significant and measurable benefits for the end user.
