Issue with Hikvision integration

Hi,

I have added the Hikvision DVR on the home assistant via the configuration.yaml. Also I have changed the Security to digest/basic. I have added the user as operator and then in home assistant I can see the different binary_sensor entities corresponding to the motion detection.

I have 6 analog cameras and 1 IP.
Accordingly, I can see:
Motion 1
Motion 2
Motion 3
Motion 4
Motion 5
Motion 6
Motion 10
binary_sensor entities.

However, the problem is that I get signals from all cameras at Motion 3.
Motion 10 gets the signal from IP camera.

What could be the problem that all analog cameras report to the same binary_sensor although all of them are recognized?

Thanks
