StarLight, ColorVu, FullColor are nothing more than marketing terms and have no real relationship to camera capabilities or any actual specification to attain those "vaunted" terms. All it take is the marketing department to call a camera "StarLight" or "ColorVU".
I'd stick with the Dahua 5442 series of turrets. Don't get caught up in the "I can see the whole yard with just one of these cameras" line of thought. Yes, you can see the whole yard but you can't actually identify, positively identify as in supply proof of who did what, with cameras like that. The smart thing to do is to buy one varifocal camera, like a Dahua/EmpireTech IPC-5442T-ZE and use a test rig to test each location, day and night, to find out what lens size, focal length, you actually need. Do the tests wearing a hoodie and acting like a bad guy, or better yet have a friend do that, and see if you can actually POSITIVLEY identify who it is and not just know because you already know who it is. DO the tests both day and night, but emphasize night tests since that's when things happen we really need to know about.
A test rig is nothing more than an eight foot 2x4 standing in a five gallon bucket filled with sand or stones. Alternately, that same 2x4 clamped t a six foot step ladder will work, too, if you've got relatively level surface for the ladder.
You can easily watch the video using the web GUI of the camera. No need for an NVR or VMS to conduct these tests. Remember, too, that Amcrest is a rebrand of Dahua and to get the price low features and quality are removed which handicap how well they can work.
