Conversion of hm4 files to mp4 file format

It does not look like that any converter exists that can convert video recordings from Lorex digital surveillance system (.hm4 files) to any other multimedia format, including the MPEG-4 (.mp4 files). The only option would be to contact Lorex support and see if they can help you out with hm4 to mp4 conversion.
