Today I bought this product. After returning home and setting it up, following all prompts and videos, the motion detection would not work no matter what I did. After completing all of Eufy's troubleshooting the tech and I came to the conclusion the motion detection is faulty. I returned it into store and replaced it with a another one, the replacement has the exact same problem. After watching videos on YouTube, it is apparent that the motion detection should work instantly after setup. There will importunely be another return needed.
