Convert HKV to MKV

Most users looking for hkv to mkv conversion likely need convert video recordings saved using Eyesight IP Camera to some standard video format like MKV. Supposedly, you can convert HKV to AVI with the SYSM Monitor program that is bundled together with the device. Once you have the .avi file, you an convert it to .mp4 format using any of the available avi to mkv converters.

Without the software from the manufacturer, it will be almost impossible to convert .hkv files to anything else, despite it being a variant of H.264 codec.
