I am disabled, so when someone comes to the door, it takes me a good while just to get up with my walker walk to the door see who it is what they want I can’t stand for any amount of time. I finally got my son-in-law to put this up for me yesterday I love it. I can talk to my grandson when he’s outside playing I can talk to people at the door without having to get up the motion. Detector works well at night I can see good. my daughters trailer is straight across from our home and I could see her front door so if there’s something going on I can see over there this is going to be so helpful. I highly highly recommend it I’ve thought about getting one for my back door just for protection so if the motion sensor goes off, don’t wait if you’re considering getting one of these especially now with the reduced in. Price for the holidays don’t white get it
