As it stands, AVTech provided a dropbox link to their video player which did allow me to play / view the files we were able to recover. I am working with the mfg in an attempt to possibly recover some data which may be more video files. The files I have viewed all stop at 2:46 am, just prior to the start of the fire, which leads us to think there may by more data we haven't been able to retreive and view.
Thank you all for your input/suggestions and I will keep you posted on the outcome.
