Hi all, first time poster. been searching for quite a while but still unsure of what recommended version of stable release firmware would be for me or process for flashing my specific nvr.

Any recommendations? model:DS-7808N-E2 / 8P firmware version:V3.3.4 build 150616 encoding version:V5.0 build 150507 web version:V4.0.1 build 150505 plugin version:V3.0.5.40
