You can't mix different types of HD CCTV such as TVI, SDI, CVI and AHD. All the HD cameras and recorders we sell are HD-TVI. They are not compatible with any other HD technology.
Our HD DVR recorders can however be used with standard definition D1 or 960H cameras. This is not necessarily the case with all HD-TVI recorders so check first with whoever is selling the equipment.
Our HD DVR recorders are compatible with either 1080P or 720P HD-TVI cameras, although we only sell 1080P HD-TVI cameras on this site.
