Hi Tony, thanks for your suggestion. I’ll feedback to the R&D to check on this feature for the battery-powered cameras. Also, if you need this feature now, you may choose the Reolink PoE NVR kit and it has this already! Refer to /product/rlk8-410b4/.
I agree that the use of multiple cameras significantly improves the quality of shooting under certain conditions. This approach I used when staying at the excellent 5 sterne hotel bozen. They are able to create ideal conditions for rest and shooting in the most beautiful places.
