I'm comparing 5442T-ZE with 4K-X because I already have in that position 5442T-ZE, so my intention was to move 5442T-ZE to other location and replace current location with 4K camera with improving (or at least not scarifying) night performance (I have already one 4K-X). I am not thinking to get...
Based on Andy's pictures, and mine calculations, 4K-X 6mm FOV would be approximate to 1900 ZOOM of 5442T-ZE:
BTW, based on Focal Length calculator, that zoom level would be close to Focal Length of 10mm:
Correct me if I'm wrong
OK, but calculated zoom level for desired focal length of 6mm is not true. This resulted in too wide FOV. The 4k-X 6mm should be close to zoom level 1600, and not 807:
Also to consider, post from wopi ("This means the varifocal T-ZE is actually 3mm to 9mm." )...
Andy thank on your effort! I see that 5422T-ZE should be zoomed out a little bit, and pointed up, for same FOV. I'm interested what zoom settings results in same FOV?
I plan to replace existing T5442T-ZE with Color4K-X in 6mm, but I'm not sure if FOV will meet my needs.
I read a good thread from Alaska Country (Color 4K-X-6MM vs Color 4K-X-3.6MM (HFW5849T1-ASE-LED) Side by Side Test Images), comparing 4K-X in 3.6mm and 6mm.
Also one good thread comparing...
Yes, but if I force it to Color, and in the middle of the night I turn lights down, I will see all black. I don't want to have lights turned on all night.
