Never knew the 4kt had been revised. The original appears to have some issues incl. but not limited to DOF, focus issues and clarity compared to 5442, processing power / memory (too many things enabled on camera caused issues). It also doens't like power being withdraw and on mine at least, settings get lost or the camera itself becomes uncontactable when IP addresses reset. Just last night I discoverd on my main camera 1 of the IVS Tripwire grids had shifted position (I wasn't getting alerts from a single area which made me look) following a loss of power the other week. I also find the exposure settings change themselves regularly including shutter speed, compression and which sub stream is enabled. There's also what appear to be compresion artefacts / noise out of the main area, and it struggles with Wide Dynamic Range. I'm sure a lot of the picture side is down to the lens, large aperture combing with large sensor. I understand larger sensors need smaller apertures to maintain dof. Non of this means you can't get a decent picture, it just means it's not as good in my opinion as a 5442 (albeit better in very low light) for picture quality or setting stability or loss of power. Unsure what altered with the S2 but hope they resolved these issues.
