SANJIE Wireless Door Open Alarm Sensor Chime,1 UK Plug-in Receiver 1 Sensor

I purchased the SANJIE Wireless Door Open Alarm Sensor Chime for my conservatory to let me know when a door is opened, and it works perfectly. The setup was quick and straightforward – no complicated wiring, just pair the sensor and chime, and you’re ready to go. The 800FT operating range is impressive; it easily covers large spaces without losing signal. The 55 chime options are a nice touch, allowing you to choose a tone that suits your environment. The volume control is handy too, so you can adjust it for quieter or busier settings. The sensor is very responsive – it triggers instantly when the door opens, which is great for security and customer alerts. Overall, it’s a reliable, affordable solution for monitoring doors. Highly recommended for shops, offices, or even home use!

Excellent product, plug in and go. Definitely an asset to the house

I have disabled kids and its fantastic to take away to make sure they are not leaving the hotel room if I'm still asleep, as they can wake at 4am. Very simple to set up and fir us it was loud enough to wake us from a deep sleep. Saved our arse a few times while away. Worth every penny.

I bought two of these. Easy to fit and programme. The chime is loud and clear. It is very handy that you can switch the mechanism on and off on the sensor fitted onto the door. Only four stars because the door sensor is unreliable; it seems that they have to be fitted so that the two pieces almost touch, and that is not possible with all doors.

Works like a charm. I have to get much stronger 2 sided tape though. The one provided isn't strong enough

Great at first but stopped working after 3 months with the plug chime going off for no reason even with the sensor switched off. Also states it takes CR2032 batteries but the model we received takes CR2450 which we now have an abundance of after returning the faulty item.

The item is good quality and works well. Easy to use and the noise is good

Easy to set up and works a treat, very good for notifying when elderly people try to leave the home.

This is a really great alarm. Scan the qr code so the video can show how to change sounds. Very easy to install

I had a friend come into my house when I was asleep. Don’t get me wrong, I really didn’t mind her coming into my house, but what concerned me the most is that I didn’t hear her enter the house so I decided to install door alarms. I researched door alarms and decided this alarm was the best for my needs because you can install the alarms on your doors and then put the receiver that alerts you someone has opened your door anywhere in the house. I choose to put my receiver in my bedroom so while I am sleeping or napping, I will be able to hear the alarm. It also has a lot of alarm sounds you can choose! I highly recommend this door and window alarm!

Works great for senior care. Ask my sister, it will definitely wake you up! I bought these for my Mom as she had dementia and wandered at night. My sister was her caregiver. 🤣

Super easy to install and works great. Make sure your door trim is flat, mine is decorative and made it harder to install. The sensor on my back door slips but hasn't prevented it from working. Lots of chimes to choose from and the base lights up as well. You can even mute the chime and only use the flashing light feature

Item works, it was easy to install but it stopped working after a year.
