How can I read the files recorded on SD/TF card?



  • Kamil Krawczak

    wow guys! I was happy with my camera and system Until i needed to check last few days worth of nvt3 files from my card. Its is impossible to scroll thru them on your mobile because you don't show/generate thumbnails so card + computer is the only way. I was very disappointed. I have 12000 files to check. I got frustrated on 5th. No playlist ? No folder adding? No multiple files? You cant be serious!?

    I challenge any of you to check 1000 files. 

    If i loose I give you one idea for free.

    This is not a software on your  company level. This is some 90s stuff. 

    Best Regards.



    PS: You could use person like me;-)

    Same deal, I want to get the video of somebody taking things from my front yard.  I try to watch on the app, took about 30mins to even find the correct spot in the video. the app kept saying offline bla bla bla, yes im on wifi, a good wifi.  But  no way to export it.  But anyways the video corrupts with garbage during the incident, I was only able to get a few frames just before and after.  I assume the motion detection triggers and messes up the 24h recording video section???   So i check the motion triggered video and no video during the time of the incident.  So I copy the video files to my computer. Same corruption and it seems to only get corrupt when something's happening.   Also it took about an hour to even find the correct spot as the file saved times on the card do not match the actual time the file was saved?  Also the camera neglects to add timing marks to the videos so they are completely unsearchable.  You cant fast-forward or skip back or anything.  Just thousands of unsearchable half corrupt files about 20 seconds long. 


    Completely useless camera.

    Completely useless cameras and service, never works with a memory card, I have 3 cameras and none of them work with a memory card, I have a subscription on one camera but never works properly, cheap Chinese crap

    Camera seems to work well, great iOS app, but that seems to be where it ends...  no app or ability to view on a Windows PC?  and what's with this NTV3 video format?  why not record in a standard video format that can be viewed using any media player?  because this NVT player is extremely buggy, limited and very slow... also why is there a seperate file for each roughly 10 minutes of recording?  and no way to configure this?  don't understand how you've survived for so long with such limited and proprietary functionality...

    Garbage. After my house was broken in to I was confident this camera would give me some useful information abou
    t the person/ people or lowlife losers that took off with my stuff. All I can say is how can Netvue put out a product like this? Luckily for me it was just stuff but what if someone was using this as a nanny cam and actually needed to playback the video? The only thing the cameras are good for is hopefully deterring someone from doing something. It took me an hour to find the spot where the people where in my house and even then I only got a few clips since the video records randomly. It will be 1:05 then suddenly it's 2:30 then it's 1:30 next it will be 12:45, it's worthless even trying to playback the video. If the people were caught I seriously doubt the video would do any good in court. It's disappointing at best

    It is possible to convert the nvt3 files with an utility like ffmpeg.

    Here is a command line to convert all the nvt3 files contained in one directory into one single mp4 file "output.mp4" that is readable with most video reader (VLC for example):

    ffmpeg -f concat -safe 0 -i <(for f in ./*.nvt3; do echo "file '$PWD/$f'"; done) -c copy output.mp4

    go into the directory and execute the command there (easy for linux or MacOS).

    Only problem audio is not recognised? What is the audio codec used for audio in a nvt3 file?

    Going off of what @flo said, I found a way to convert the files on Windows as well also using ffmpeg

    First, go here and follow the directions to install ffmpeg.

    Create a new text file and add this to the file.

    for /f "tokens=1 delims=." %%a in ('dir /B *.nvt3') do ffmpeg -i "%%a.nvt3" "%%a.mp4"

    Rename and change the file extension to .bat instead of .txt

    Place the new batch file in the folder you want to covert the files for.

    Run the batch file and wait. It will generate a new mp4 file for each nvt3 file.

    CoNiGMa did you manage to decode the audio on this? 

  • flo

    So far, ffmpeg can't identify the audio codec. It is a pity that Netvue does not provide the audio codec. Or a software that can read multiple of their nvt3 files and export them in a popular format. Very amateurish!
