I’m in the same boat. Just picked up an Arlo Pro 4 and was sorely disappointed that it only had the 4 anchor points. It’s literally the only reason i bought this model; the flexibility of more anchor points. It sounds like it’s available on the Pro 3s which doesn’t make much sense but hopefully just means they’re working on this one next. Looking forward to the update.
I was surprised to discover that the activity zones do not have more than 4 corners. The video shows the ability to draw a polygon which means you can shape the zone around unwanted areas. Can you update the camera firmware to support the 8 corner zone like the Arlo Pro 3?
