Following a vehicle theft from in front my house, I became keenly interested in DIY camera surveillance. One of the types I tried is a TUYA Smart Battery Wifi Camera. Nothing but a sticker on the box genuinely indicates it is marketed by TUYA. Most everything is generic black and white documentation.
The camera RTSP's to a TUYA cloud, and there is nothing about the wireless feature that I like. It only connects to an open network. There is no management access to the camera core.
The quality cannot compare to Lorex. One feature this camera has, which a Lorex system does not, is an SD-CARD slot.
I positioned the camera for an overnight watch of my backyard. It is motioned activated, and only captured my positioning and a single clip that seemed to be the result of the neighbor's porch light.
The SD-CARD contained a DCIM directory and because the camera is not configured, a date of 1969. The subdirectories had a simple .info file with the content "V1" and a handful of .media files.
Neither /bin/file, binwalk, nor vlc could make sense of the .media files. Some lucky search results indicated this was a NHNT interleaved video format.
I took a wild guess that FFMPEG might be able to transcode. Sure enough, it does
ffmpeg -i 0001media /tmp/video.mpg
And there you have it.
I wrapped the conversions in to a basic shell command.
I=1; find -name *.media | while read X; do ffmpeg -i ${X} /tmp/$(basename $X)_$I.mpg; I=$((I+1)); done
