Ecobee SmartCamera via HomeKit to Surveillance Station or even VLC

Goal

To use camera proxy stream as source to Synology Surveillance Station (Synology SS)

Current setup

The ecobee SmartCamera is not directly compatible with Synology SS. It is however HomeKit compatible and thus I have integrated into Home Assistant via the HomeKit Controller Integration.

I can access the camera proxy stream via the sample url

Question

Is there any way I can grab the video that HA is proxying and use as either an rtsp or hls stream into Synology SS?

Did you ever find an answer to this?
