Ring motion sensor is useless in my garage. Probably returning the whole system

I got my new Ring 14 piece kit yesterday and was pretty excited to get it set up. Got both keypads working and both motion sensors.I placed one motion sensor in the corner of the garage at 7'6", as well as tried several other places, and it only triggers motion at about 10 feet or less. I switched in the other motion sensor and got the same results.I thought these things were supposed to pick up motion up to 30 feet?My garage is 22' x 24' so everywhere in it should be picked up by the sensor. I stood about 15-20 feet away and waved my arms over my head and it never triggered.It seems to pick up further distance in my living room. The temperature in my living room is 73 degrees and in my garage it's 86 degrees.Does heat affect the distance these pick up? If so, I will either have to put multiple ones in my garage or just look for another solution.
