DaytechWireless Door Chime, Door Dinger for Business Entry/Store/Home/Office, Door Alarms When Opened with 800 Ft Range,20 Chimes 5 Adjustable Volume 2 Sensors + 2 Receivers

It's Perfect it provides just what I needed

I purchased the set of 2 sensors and 2 chimes for my shop. I pulled the battery tab from each sensor to activate the sensors, then installed on the front main entry door and the other on the shipping/receiving door. I plugged in one chime in the back office area and the other in the warehouse. BAM, it all works.I should add the main entrance sensor is about 100 feet to the chime in the warehouse with multiple walls in between and it works perfectly. Each sensor sounds both chimes which I really like. I then adjusted the chimes type and the volume level. You can turn the volume off as well.This is a completely independent wireless system with no connection to WiFi. Very quick and simple to install.Lastly, the sensors do have a watch type battery. I have no idea how long they will last, but I imagine they will last for months before needing a battery replacement.

This was a very affordable and simple solution to entry notification at our office. The selection of chimes is nice so you can choose a fitting notification sound. The range is nice also. The only downside is we have mild door traffic(maybe 30-40 entries max a day) and we have had to replace the batteries on the door piece twice already in 4 months. They aren't your typical batteries also, you can probably buy them anywhere but definitely stock up if you have people in and out often.

Hard to install .very disapointed

I installed the Daytech Wireless Door Sensor Chime at my home and it's been a fantastic addition for our family's peace of mind. The setup was a breeze and its range is impressive, easily covering the distance across our property without any signal issues. With 55 chimes to choose from and 5 volume levels (including a mute mode), it's versatile enough to suit any preference or need. The LED indicator is a nice touch, especially in a busy environment where the chime might be missed. Whether it's for a business or home use, this door open alert system provides a reliable way to know when someone is entering.

I bought this for my store. Love that they're are 2 so I use one on the mask for and one on the front. But I hate how it rings twice when they open the door and twice when the door closes. On some days it's really annoying. The other ring tone options are way to long and sing-song to use as a door chime. So it works well but I would not buy again for that reason.

Excelente

Great price for these. Glad I was able to purchase these at a fair price and give some peace of mind as far as safety for my son. would purchase again.
