https://community.arlo.com/t5/Features/motion-detection/m-p/3021#M9243 <P>I purchased an arlo security system with one camera. The camera was doing just fine when you recorded live but then i went to complete the setup over the weekend and set it to positioning mode. then I went into motion detection mode I quickly realized that the camera would not detect any motion outside the glass doors in my kitchen. Then I came inside to test the motion detection inside the light would not blink reagdless of the how sensitive i would set the motion detection.&nbsp; So I brought it back to Best Buy faulty camera and exchanged it for another one.&nbsp; I am home now with the brand new camera and it is the same problem will not detect motion. I guess I will be returning this camera too and will be purchasing the Piper home security see if that one works better.</P> Mon, 03 Oct 2016 02:01:49 GMT Johnrap 2016-10-03T02:01:49Z https://community.arlo.com/t5/Features/motion-detection/m-p/3021#M9243 <P>I purchased an arlo security system with one camera.
