I have six of these cameras running on a DS-7608NI-SE/P NVR. They are all running with the V5.2.0 build 140721 firmware that they came with and working very nicely with this NVR.
I purchased a seventh DS-2CD4065F-A (a year later) and it came with V5.3.0 build 150513 firmware and it does NOT play nice with the older firmer ware on my NVR and based on my research it's due to how security changed from V5.2.X to V5.3.X camera firmware. Looking on the Hikvision FTP site, it does not appear that there are any firmware upgrades available for my NVR that will get it to a level where it can play nice with this new camera.
What I'd like to do is downgrade this camera to the same firmware that I have on all my other cameras that are working for me right now. I tried to use Hikvision TFTP on all of the 5.2.X firmware versions available on the FTP site for this camera and it fails to update. I'm sure I'm using TFTP correctly because I tried 5.3.0 build 150513 (same as what it shipped with) to unbrick myself after the failed attempts and it accepted that firmware just fine using TFTP and the camera is operational again.
Is it possible that the camera hardware simply won't accept anything lower than 5.3.0 or is there something else I'm missing here that I need to do to make this work?
ETA: All of my cameras are US retail versions if that makes any difference.
