I'm looking at CCTV cameras. Doing my research on the forums, Dahua seems a pretty popular/respected brand. Can anyone tell me what HD-CVI is and what it means in practice? From what I gather, I think the cameras aren't IP cameras.
Is this a downside? Best practice seems to be well and truly keeping any and all IP cameras well away from the internet anyway, so I'm not sure there's any harm in using non-IP cameras.
Basic requirements: 4 cameras, dedicated NVR (or equivalent), single run of cable to each camera (i.e. POE if IP cameras), decent resolution cameras, don't need remote monitoring/live alets/phone app, must be simple to use. Budget is approx $1500, but I'm not paying for it so am really aiming for simple and straightforward, not cobbling together something from 3 different suppliers and compiling my own kernel.
Bad experiences have completely turned me off Aliexpress and its equivalents, so really looking for a local supplier.
