This thing works like a charm! It’s incredibly easy to set up. It picks up every little movement and is easy to play back. When it’s dark it switches to night vision. I go to work before my teenage daughter gets up to go to school. Sometimes she sleeps in and I have my camera pointing to her door. If she doesn’t get up I turn on the siren. That gets her right up! I’m going to get one for my front porch now. I like that I can snooze the notifications because it really does pick up every movement, even the cat walking by. Great product!
