• DVR365,
• DSD304,
• DSD316,
• Other closed circuit security cameras in the CCTV system.

DAV files can be played in the DVR 365 application. The can be also converted into some of the popular formats, like AVI, MPEG, in order to make them available across larger number of players. The DVR365 system was substituted by AlienDVR – offering better parameters and wider possibilities.
