Firmware archive of 12.5 MB for the Hikvision DS-7204HGHI-SH digital video recorder, also referencing board DS-80193 and OSP, at revision 1.3. The name presents the two codes as alternatives, so the DVR model and the board number may both identify the target hardware. Check the main board marking and revision before flashing, since the wrong firmware can leave the recorder unbootable. Extract the archive to see whether it contains an upgrade package or a raw flash dump. If it is a dump, read and save the existing chip with a programmer before writing.
