Our HD over Coax cameras are predominantly HD-TVI cameras, as HD-TVI emerged as the leading HD Analgoue format ahead of HD-CVI/AHD. Many of these cameras allow you to select the format output for older DVRs but not all so do check. If you have a newer DVR you will find it supports all HD over Coax formats (Aside from HD-SDI, which went by the wayside)
HD over coax offers a more affordable alternative to IP and is an ideal upgrade route to an ageing non HD analogue installation (TVL).
HD-TVI is also known as Turbo Analogue within the Hikvision/Hilook range.
