strategicsecurity 0 Posted November 27, 2017 Hello folks, I have a question for whoever might know the answer from having this scenario on the field. Dahua XVRs are now compatible with CVI, TVI, AHD, CVBS and IP. We mainly use HDCVI PTZs when we add one to a system, so we have been OK. However, we may now need to add a HDTVI PTZ due to budget, and we are wondering if the Coaxial control will work? Has anyone had this scenario, and will a 3rd party HDTVI or HDTVI Hikvision OEM one work? The PTZ settings of the Dahua XVR is one of two choices: Control Mode: HDCVI Protocol: HDCVI3.0 or HDCCTV2.0 Control Mode: Serial (by RS485) Protocol: Many choices like Pelco D and others We don't particularly want to use Serial RS485, which we know will work. Thank you for your input on this subject. Share this post Link to post Share on other sites
