Unless Reolink can get their cameras with Hardware IDs of IPC_523128 to perform better with Blue Iris software, I would reconsider purchasing them. No firmware updates for 2 months (since Aug 24th, 2021) v3.0.0.494. This version of firmware degrades frame rates and key-frame rates if you view the main stream through Blue Iris. When in "Night Mode" (black and white) the frame rate on both the main and substreams degrade to about half of normal daytime frame rates.

Are you developing new firmware to address these issues?
