HikVision Intercom Unlock functions

[Kostas Marmarokopos]

Hello everyone.
We have the following scenario:
1 outdoor station DS-KV8102-IM and 3 indoor monitors DS-KH6310-W.
The system is connected and working. The problem is that the customer needs to be able to Unlock 2 doors, with just 1 outdoor station. This doesn't appear to be possible because the outdoor station has 2 unlock options (NC and NO) which are armed simultaneously when the unlock button is pressed. This is not good for us because we want to be able to choose which door to open, not both doors at once.
We have asked this from the local supplier and they provided as with a customized firmware for the indoor stations which provides 2 Unlock buttons at the screen, but they are not sure how to use the second unlock button. Currently When pressing the Unlock 2 button we get a message "Unlocking Failed". Pressing Unlock 1 button opens both doors at the same time.
Do you have any experience with this system or can you think of any way to accomplish the task?
I have uploaded images from the indoor station
Thank you,
Kostas

Hi
I know that you must use module on RS485 name DS-K2M060. It allow controll 2 doors but for all doors you can setup only the same time relay. I write to Hikvision but he tell me that he stop support this generation of videointercom. Noo good
