MOTION DETECTION RANGE ARLO PRO 4

[TR52]

I HAVE A ARLO PRO 4 MOUNTED ON THE SIDE OF MY HOUSE 8-1/2 FEET ABOVE GRADE AND IS POINTED SLIGHTLY DOWNWARD. ADDITIONAL INSTALLATION MATTERS ARE AS FOLLOWS: 1) IT FACES NORTH WITH NO DIRECT SUN INTERFERENCE, 2) IT IS LOCATED 25 FEET FROM MY WIFI ROUTER INSIDE MY HOUSE (2 X 4 WALL WITH WOOD SIDING) 3) MOTION SENSITIVITY IS SET AT 100%, 4) ACTIVATION ZONE ONLY INCLUDES MY DRIVEWAY SO THE AREA IS NOT MORE THAN 25 FEET FROM THE CAMERA, AND 5) THE BATTERY IS 100% CHARGED. 

PERFORMED ACTIVATION TEST AND THE CAMERA WILL ONLY DETECT MOTION WITHIN 12 FEET OF THE CAMERA. THE ARLO MOTION DECTECTION RANGE CHART INDICATES THAT THE PRO 4 HAS A MOTION SENSING / ACTIVATION RANGE OF 25 FEET. WHY WON'T THE ARLO PRO 4 SENSE MOTION FURTHER THAN 12 FEET FROM THE CAMERA??

When you do the test, are you walking straight towards the camera?  Or are you walking across the field of view?

In general, Arlo cameras are more sensitive to motion across the field of view, and are more sensitive to motion at the bottom of the field of view than the top.
