"Environment Error" on DAHUA VTH2421FB-P during config with VTO2111D-WP

thank you very much this solved my problem, now i am connected to VTO and i can configure it. Sorry to bother you with NON Dahua issue, but was looking to me as Intercom issue, as i also have Dahua NVR IP camera system and i had no this kind of issue. Once again. thank you for you r support, which is highly appreciated.
 
VDPconfig was included in ConfigTool in dahua toolbox. This works for most devices unless the firmware is not too old (<V4).
 
Hi, I was wondering if anyone can help me out with setting up my Dahua Intercom

There was initially some water damage to the outdoor intercom, so I purchased a new one and now I have it installed.

The DMSS app shows that Main VTO, Sub VTO and NVR (4 cameras) are all working

However, when I press the call button on the Main or Sub VTOs, the doorbell does not ring at the main intercom interface

I tried to default reset the intercom, but now it can not complete the configuration of the devices. It is saying "environment error".

I followed the steps above and downloaded the Dahua Toolbox config and it is only detecting the NVR but not the VTOs.

I used the 192.168.1.108 and when I go to Local Settings, Video and Audio, it correctly shows the VTO image

Is there anyone I can contact within Australia that can run through all of this?
