Hello I have the same problem VTO3211D-P2. original in 4.3 I mistakenly install 3.3 and can't get back to 4.3? which technique used?
Bonjour, j'ai eu le même problème, il faut revenir sur la version anglaise précédente ou il est possible de sélectionner le nombre de boutons. les configurer et ensuite effectué la mise a jour 18.104.22.168I purchased a VTO3211D-P2-S1.
The Polish language was missing.
Following the instructions, I updated to the latest version 2019-10-19 V4.400.0000000.3.R.
The update was successful.
Unfortunately, it turned out that I have one button available, how to activate the second button?
What is the most up to date MCU for VTO3211!?
Yes - indeed and maybe straighten out some bugs here and there. The current approach is not thorough. Often bis and pieces.Too bad - dahua has much potential imho. If they would be a bit more "open to public" they could make a lot $$$.
Hmm, that’s bad. Hopefully not the basic one which is easily cloneable with a nfc mobile phone
