Detection range on battery cam way less than PoE cam

A couple of years ago I set up a Ring security system with four Ring PoE cams (Stick Up Cam Elite with POE adapter) at my in-laws' house. The system performs very well, picking up all the motion disturbances around their house. Before I used a motion zone to exclude the street, which is 175 feet away, alerts were often generated when a vehicle went by on the street. A PoE or AC-powered setup is not practical at my house, so I bought two Stick Up Cam Battery cameras (Gen 3, I think), expecting similar performance. Unfortunately, performance seems not similar at all. The sensitivity is very poor. About half of daytime motion events are missed. At night, all motion is missed. One cam is mounted on a tree trunk in front of the house, aimed at the house and driveway. The other cam is mounted on a tree trunk behind the house, looking at the back of the house, driveway, deck. The distance between the cams and motion I want to detect is 40 to 60 feet. I have set every setting I can find to maximize motion sensitivity. - turned off Smart Alerts - turned off Advanced Motion Detection - increased the motion sensitivity slider to the max - set motion frequency to Check Frequently - I tried Color Night Vision on and off; no difference in detection Is there anything else for me to try?
