Arlo Pro does not detect motion 20 feet anymore with 100% settings

When first installed my Pro it picked up motion 20 ft away. Now only up to 5ft and only at an angle?  Doesn’t detect motion further out. At 100% setting

Unfortunatly, PIR Motion detection is really the only option for a battery powered camera, and while it does a great job minimizing false alarms (blowing tree limbs, sudden changes in light, etc...) it's not always accurate at detecting people. I'm not an expert, but I believe there are alot of veriables that come into play.... like weather conditions, how fast someone is moving and their direction, as well as the clothing they're wearing.
