HD Analog

A family of progressive scan analog interfaces for CCTV surveillance systems. Rather than change CCTV systems entirely to IP cameras, HD Analog options were introduced in the 2010 time frame to provide easier upgrade paths. HD Analog cameras support 1080p video but also use the existing coaxial cable network. See network camera, CCTV and surveillance camera resolutions.

CVBS (Composite Video Blanking and Sync)
CVBS is not HD but is listed here for reference. It is the traditional 480i (NTSC) or 576i (PAL) analog signal that connects via an RCA or BNC cable. See NTSC and PAL.

HD-TVI (Transport Video Interface)
An open standard for 720p and 1080p video, HD-TVI is available in numerous analog surveillance cameras using coax up to 1,600 ft. and Cat 5 twisted pair up to 700 ft. HD-TVI also supports IP cameras.

HD-CVI (Component Video Interface)
A proprietary standard for 720p and 1080p video, HD-CVI also supports IP cameras in certain configurations with cable lengths similar to HD-TVI.

AHD (Analog High Definition)
An open standard for 720p and 1080p video with 1080p cable lengths up to 1,600 ft. and 720p to 492 ft. AHD does not support IP cameras.

HD-SDI (Serial Digital Interface)
HD-SDI is not analog but is listed here for reference. HD-SDI is a digital interface at 1080p. It uses coaxial cable to allow integration into existing CCTV systems when hybrid DVRs are installed. However, cable distances are considerably shorter than HD-TVI, HD-CVI and AHD. See HD-SDI, SDI and hybrid DVR.
