Door Chime,SanJie Wireless Door Sensor Chime When Door Opens,Door Entry Alarm Chime for Business/Home/Kids,500 FT Range,26 Chimes 5 Adjustable Volume Door Ringer Alert 2 Sensors + 1 Receivers

I don’t usually leave reviews, but this is the best thing I’ve bought to feel calm and at peace now that my 5-year-old daughter sleeps on her own. Super easy to install, different tones to choose from, and it literally brings peace of mind knowing that we’ll be alerted as soon as she gets up. 5 stars for sure!!!!

We used these on 2 wood doors and one metal. All worked great. The magnet worked both side by side the unit and also top to side, as one door, the bell had to be inset as the frame stuck out to far to be a smooth fit. The sound was adjustable & worked several bedrooms over.

Bought these because my daughter wanted to feel more safe. Very easy to install on doors and we can hear it throughout the house. We just unplug it during the day and plug it back in at night. There are a couple options for sound . We've had these for months now and they are still holding up so sticky part is great. Would definitely buy more.

This was easy to set up, it only took a few minutes. I have a different sound for each door so that I will know which door is the one being opened.UPDATE* I have not had this for several months and although I still like it for the most part, I had to take away a star because now, one of the sensors just randomly goes off.

This door alarm was sooo easy to install and works great! It dings when my 99 yr old motherOpens her front door. It alerts us when she is on the go!

My daughter moved out of her crib and into her "big girl" bed. I was nervous to lock her door, but wanted to be alerted (loudly) should she leave her room at night. This doorbell works perfectly! The sensor is on her door and then the chime is in our room. It's loud and flashes blue (we can even hear it if we're downstairs). Neither my husband nor I have slept through it. When she's playing during the day, it's easy to turn the sensor off with a simple switch on the sensor if she's going in/out of her room. Definitely gives us the peace of mind we were looking for!

This does exactly what I need it too.. We bought this so that we can have something in our room while we are sleeping to hear if the kids walk out especially our 6 year old that is a sleep walker. And with having a pool we want to be very cautious. It has sound settings so you can determine how loud it is. I give it a 10/10

Works well with all the multiple settings. Has great noise range! Easy install. Only down side b is the security alarm may randomly chirp/ring.
