i failed to remove admin password for JUAN JA-R5104H DVR, so i just plug the HDD to my computer, and copied all video files. files are named file0000.dat divided into 64MB pieces. when i play the video on VLC /with demuxer h264 config/ it gives 4 camera feed about 1 second long from each other, so basically i cant tell whats what because camera's switching too fast. anyway to make it more watchable? or divide it into 4 different file, or screen?

You can use ffmpeg or vlc to export a single frame every n frames and then make a new video from the (huge number) of extracted frames.
Whether this will be easy or complex may depend on the exact frame rate of the original video, see

Or maybe (making "three passes") use the odd and even frames conversion?
Using Avisynth enabled ffmpeg, see

But I would first try with something simpler *like*
ffmpeg -i input -vf framestep=2 output
