Sorry for starting a new thread. There is already a thread called Date and Time does not update. but it's on page 5 already and until now there is now solution. I like to bring it up and it looks like, the only way is to start a new thread.
Now guys from TP-Link, tell me please, why are you selling a so nice peace of hardware like the C200 together with a so crappy software (firmware) ...???
At the moment I'm using 3 C200 and 1 C310 plus a few P100/P105. All of them don't know the correct time, that's why so many things are not working. The schedule part for example can't work properly without knowing time and date.
In the thread I have mentioned I have read - sorry - many nonsense from you but there was no solution. And the only solution for many users here is, to return there TAPO devices to the seller and try another brand. Is this what you like them to do ...???
It's very simple, check your settings using ONVIF Device Manager and check your cameras. In case you don't know it, you can download it from https://sourceforge.net/projects/onvifdm/ for example.
For my C310 it shows me:
Here I can switch DHCP to 'OFF' for example and change my setting. With the settings above my cam will work well and it's using the correct time and date. And of course, I can save my settings as long I don't reboot my camera. After a reboot it's going back to the old settings from the cloud. This issue should be easy to fix on your side.
And now let's do the same for C200:
Can you see the difference already? Yes, you are right, I can't change DHCP to 'OFF', at least not really. I can change it but I can't save my changes so it will go back to the old settings after pressing 'Apply' and with the old setting the camera don't know correct time & date.
Is this really to complicated for your developers to fix it?
Do something before you have ruined the reputation of TAPO totally!!!
