User Reviews

Steve Chandler – This is Great.The setup was so easy. The sound from the base station is great not too loud or obnoxious. I have a gate this will let me know that someone is there before I can see them on camera. During testing, I now want an extra sensor for a set of stairs.

Fritz Koenig – Bought this back in ’14 and it still works well. Change the batteries once a year. I’d say it picks up vehicles 95% of the time. We have a 200 ft drive and our front yard is solid trees so we have limited visibility and this helps. Occasionally a critter or deer set it off in the middle of the night but that’s rare. This sucker is loud too. I paid $45 for it – for the price and ease of operation, it’s a no-brainer for my situation. When this one quits I’d buy another.

Lily – Background. I live in a secluded area, surrounded by forest. We’ve been robbed multiple times, twice when someone was home 🙁 and I have a baby. This little thing has given me so much peace of mind. I’m notified anytime someone approaches the house. I hear the beep and I check my security cams on the app I have on my phone and I can see whats going on. It does pick up cats, deer, raccoons but that’s ok with me. My husband and I share a car, so when he is at work I’m home with the baby and there is no car in the driveway. This product and my security cameras have really helped me feel safe when I’m alone. Oh, and it’s rained pretty hard and it still works great.
