Beta balance monitoring eufy doorbell

I bought a eufy doorbell. Used different settings but with 2 weeks the battery is at 48%. I live near a street. Use human only detection, sensitivity on mid. And I use the beta option balance monitoring.

I think the balance monitoring can use some approvement. Because I still get multi detections within a short period. I now have made the detection zone smaller.

Wirering the doorbell in my case is not that easy.
