My VTO must have SIP in order to work with VTH5221DW-S2
Is there any way to upgrade to a SIP enabled FW?

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 4.4.0.3I 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?
I suggest to upgrade to lastest firmware and MCU. Use General_VTO3211D_Eng_P_SIP_V4.300.0000000.4.R.20190306 and a language pack like General_VTO32XXX-data_EngTurSlkPldHgrFinCzeBul_P_32M_SIP_PART_V4.300.0000004.0.R.20190629. ....
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
