I possess a DS-2DE3A400BW-DE, specifically the Pro version rather than the Value series. Regrettably, attempting to install firmware intended for the Value series results in an error. I have discovered only a single Hikvision website that offers firmware compatible with the Pro series (DS-2DE3A404IW-DE) all other Hikvision country sites predominantly feature the Value series firmware, which is incompatible with my device. I would greatly appreciate any assistance, as this firmware is required to hopefully resolve an issue I'm encountering with the Pan-Tilt-Zoom functionality and the initial position setting, which is not operating correctly.
