Hello @Solla-topee and thank you for providing additional options.

I found numerous unanswered posts that the suggested NVR and Tapo C320WS are not working properly due to unchangeable "admin" username which camera requires to have at least 6 characters - like here: https://community.tp-link.com/en/smart-home/forum/topic/562964?replyId=1162218. I am not sure the combination is meant to work smoothly.

Having the necessary recordings on the SD card but not being able to copy them out (unless taking a ladder and pulling out the memory card) is a pity. That should be really doable without spending extra 100 bucks for NVR and some more for HDD.  

I am also ready to use the Tapo Care - how can I download lots of daily detection videos in a bulk? It seems the app supports downloading only one-by-one, or bulk deletion. But no bulk downloading...

  @Mikekee If you could download the videos over SMB / FTP or HTTP , They couldn't make money of you with their TAPO Care .... 

I'm regretting more and more, getting 4x C320WS cameras..  I guess cheaping out was a mistake.. It's also weird that these cameras are so bad, considering that TPLink Routers are so damn good :( 

  @Solla-topee Does VIGI Security Manager Support Tapo C310 ? I have tried to add my Tapo C310 but I have been unable to do so (The camera works with ONVIF Device Manager). The camera is not detected by  VIGI Security Manager and manually adding is not successful (username is greyed out).

Please clarify.

  @Solla-topee Please provide a solution for downloading videos from Tapo C310 cameras not using cloud features, but with SD card. Either by referring to 3rd party software that works with Tapo or TP-link software. What exist now is very disappointing wrt. this basic feature. I have seen reviews of the camera and bought one. installed a 128 GB SD card, but never imagined it would be impossible to download videos from the SD card without physically opening the camera.

I was planning to buy more cameras, but this will have to wait until video download is improved.

  @Solla-topee 

It would be extreme awesome if you could add a HTTP WebAPI on the cameras - it would likely take a developer 1-2 days to make and add a lot of value to the product. 

With such an api we could make programs that automatically download new videos by polling the cameras every 5 minutes or so. 

  @Solla-topee Thank you for replying and thank you for logging the request and passing it along to the developers. I hope it is given some priority.

Your link does not work where I am (Norway), but bying another piece of hardware just to be able to access the videos on the SD card is not an option. This is a software problem (I am a software developer myself) that can be fixed. The camera is marketed as an outdoor camera so it is not an acceptable option to suggest the camera is taken down and opened just to be able to access the videos stored. My camera is mounted with screws high on a wall following the instructions provided.  Thank you for your consideration.
