Hi
I have an older style 4CH AlienHero (non HD model) DVR with BNC connectors. Both the manual and their support cannot tell me what the specification for the cameras to be used with this device is.
This is the on-line page to my DVR: http://www.aliendvr.com/hero/alienHero_spec.html#
My requirement is for wired outdoor use, with IR, compact size, BNC + 12v power.
In their manual they list 2 cameras NightDevil cam220 and Cub PTZ, however we have 2 cameras already connected which are neither of these and I cannot identify the specification of the existing cams as they have no markings.
Can I fit any camera with BNC video connector with a 12dv power adapter and if not what should I be looking for?
I read that the main types are CVI, TVI, AHD, IP. I suspect IP is out of the question as its digital and uses cat5?
So can I use any CVI, TVI, AHD camera or or only one type?
Also does the number of lines TVL matter, or can I simply choose the one with the greatest value for better picture quality?
Hope someone can help, it does seem very confusing to me.
