DAV is an encrypted format created by a DVR365, standard media players won't work for DAV files. An easy way to open and play DAV files on Windows PC, just use the official DVR365 Player software, it only works on windows pc. There is no dav player for Mac OS X. So you can hire a great DAV Converter for Mac to convert DAV files to MOV/MP4/AVI on mac.

I was recommended by my friend to use UFUSoft DAV Converter for Mac to convert DAV to mov on mac, and it works really.
