I'm really starting to regret buying Dahua cameras and NVR. Their software is garbage and apparently there's no way to convert this DAV so a different computer can view it!
For easily getting video clips off, I'm not a fan of Dahua's NVR... I ended up switching to
Blue Iris. Love love love my Dahua Starlight cameras though. Zero regrets there!!!
There was an incident in my neighborhood Saturday night. Police were able to use the Blue Iris app on my iPad (out in the street) to easily review recordings. They asked for a few minutes (from different cameras) to be emailed to them, which I was also able to do from my iPad (while out on the street with them). Blue Iris definitely had a learning curve for me, but once up and running,
easily exporting video is definitely something it excels with (IMO).
What surprised the heck out of me was how useful the police found the recordings from my two 5231s that were zoomed out for wide "overview" shots of the front/side yards. These two cameras couldn't give facial recognition if you're more than 5 feet away from them, and the police were looking at areas about 100 feet from the camera. They said they got enough info to easily make some arrests. I do have addition cameras zoomed much tighter on key areas around the yard, but they didn't catch any of the shenanigans happening that night.
