Dahua DH-SD6AL830V-HNI: record uncompressed and stream compressed

[saveconi]

Hello,
I am using a Dahua DH-SD6AL830V-HNI with Zoneminder 1.33.9.
My goal is to record locally without compression and stream over the network with a good level of compression.
Is it possible?

This camera has 3 streams (1 man and 2 subs): I could stream locally the Sub1 that is a 1080p stream and record locally stream Main (that is 4K).
Is it possible?

Regards

Sarah
