What is the best way to view an .arv file?

[iveast]

I have a security camera system at work & i need to pull video from it and view it on my MBP. The file it gives me when I output from the machine is an .arv, (which I have never heard of) but I cannot seem to find software (preferably freeware?) to read it. The system gives me a viewer ("DVR Viewer"), but it is an .exe, so it won't run on my system. Thanks for the help!

Bizarrely there doesn't appear to be anything for the Mac, but you'll find a CCTV DVR viewer for the iPhone on the iTMS
