Synology Surveillance Station: Looking at cameras make CPU utilization go up a lot

Hi, I integrated Synology’s Surveillance Station into HA and it works. But if I actually look at the camera stream, the CPU utilization in the Synology goes up from 10% to around 30%. When I open another client, the CPU is so hammered that Surveillance Station becomes unusable.

I couldn’t find any settings to tell HA which of the two streams to use or something like disable transcoding. Are there any options I could use to mitigate this? Any workarounds?
