Hello... Help me understand a few things regarding filter size on a camera. (EDIT: SENSOR SIZE! not filter size, lol, ugh)
What does 1/1.8 " or 1/2.5" or 1/2.7" actually mean? Is there a picture I can reference to understand what it really means and why one is better than the other and how it effects things like the cameras CPU ability to process AI, how it relates to MP of the camera, or how it handles day/night picture
As I understand it, the smaller the # the better... ex: a 4MP with a 1/1.8" seems to be better than a 5MP with a 1/2.7" filter. or, a 8MP camera with a 1/2.7" is way worse than a 8MP with a 1/1.8" and a 1/1.2" would be even better ... but what I don't understand is the "why", yet. (I tried searching for info on this, but it's a hard term to search for on the forum, and @wittaj explained it to me once, but I admit I've since forgotten the reasoning behind it)
In short, I have had a BUNCH of problems with this particular camera for nearly 6-8 weeks now: DahuaWiki and have decided to replace all of them with IPC T5442T-ZE cameras from @EMPIRETECANDY which I bought 6 of last night. I'm losing some extra features by making the swap but I need IVS reliability and so far, the N55DU82 reliability for IVS has been completely awful. My initial IVS tests with the (1) IPC T5442T-ZE camera I bought earlier this week had much better reuslts with IVS rule consistency than the IVS consistency of the N55DU82, even thought the N55DU82 is a much more expensive camera (so I assumed better, but definitely not better specifically related to IVS).
I really thought it was me at first and my lack of knowledge (I'm really ignorant to sooo many things I read here still). But thanks to @wittaj for the assistance and spending time looking at the N55DU82 cameras with me and validating that the IVS capabilities of the N55DU82 are horrible and terribly inconsistent. (I think even he was surprised). So basically I decided to swap them out with a proven camera model that works well with IVS rules.
I also have 3 expensive ($800) thermal cameras that I still might need to replace with something else because they don't work so hot either and IVS on them is inconsistent too, plus they have numerous bugs that I have L2 cases open with Dahua and Dahua HQ. But, I'm holding off replacing those thermals, for now at least. First things first and address the non-thermals...
Anyway, sorry for babbling, main point is, help me understand filter sizes per MP, etc. ! thanks!
