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, 2 Sensors + 1 Receivers

Serious Peace of Mind for Parents
This door chime has been a game changer for our household. I use it on my toddler’s door so I know immediately if she gets up in the middle of the night, and the peace of mind it gives me is priceless. As soon as the door opens, the chime alerts me right away, which makes me feel so much more secure as a parent.Installation was incredibly easy. The sensor and receiver come already paired, and I just plugged the receiver into the wall and used the adhesive to place the sensor on the door. No tools, no complicated setup. The long range works perfectly throughout my home, and I love that it has multiple volume levels and chime options so I can choose what works best for day or night use.The functionality is excellent, the alert is reliable, and the build quality feels solid. I also appreciate that it saves your settings if it gets unplugged. This is such a great value for the price and a must-have for parents with curious toddlers, caregivers, or anyone who wants an extra layer of awareness in their home. I highly recommend it.

This is just a brief chime, not a continuous alarm.
Just be aware this is a magnet8c interlock chime, not an alarm. It only plays for a few seconds and then stops entirely if door is left ajar. It is nice and loud if not hard of hearing though.

Great device!
This is EXACTLY what I was looking for. Most devices the alert makes a very piercing sound. This actually has different friendly sound setting alerts. Chimes, door bell “ ding dong” and musical tones. ( even holiday! ) I care for a friend with dementia and this is great because it lets me know when she enters / leaves her bedroom and the bathroom. I bought the 3 pack with 2 plug in alerts that I can easily set up in different locations This is also great for young children to alert you if they open a door. Teenagers so you know when they arrive home safely at night if you fall asleep. For any reason to alert you if something opens!
