Milestone Dual-Recording feature in MIP SDK

Hello,

1. If Milestone Dual-Recording is configured, how to find matched cameras in SDK (mapping between cameras)?

2. If we have primary and secondary cameras, the primary may be down. We would like to implement the logic - when the stream from a primary camera cannot be open, we will show the stream from the secondary camera. Is there any build-in way to do it? Or how to understand that the primary stream failed to open (available or not)?

Thank you,

Vadym

1. No, there is not such a functionality in Milestone products.

2. I have talked to Milestone Development but they said there is no such a buildt-in ways to do in SDK.

But I am wondering if Edge Recording might be a workaround? Please check this article -https://supportcommunity.milestonesys.com/s/article/Configure-edge-recording-for-Axis-cameras-in-XProtect-Corporate?language=en_US
