Is there a distance limit? One in my back seems only to work when I’m close to it and the one looking at the front seems to work intermittently.</P> Wed, 02 Jan 2019 16:22:10 GMT https://community.arlo.com/t5/Arlo/Arlo-is-there-a-distance-limit/m-p/1664448#M61933 AndyDitch 2019-01-02T16:22:10Z https://community.arlo.com/t5/Arlo/Arlo-is-there-a-distance-limit/m-p/1664456#M61934 <P>The cameras use a PIR device to detect IR / motion... the max distance for people is about 20+ ft for Arlo, 25+ft for Pro/Pro2.
