Review: Small, reliable, functional and long running sensor! - So far - very happy with thus contact sensors. Beside the ones in the house, got an extra one for the side door outside (covered). 1. Easy setup. Super quick and straightforward. No rocket science, no IT degrees, not asking chatGPT on how to's. App guides you in few easy steps. And no wires!!! 2. Works reliably. In 2.5 years of using Ring Alarm and sensors I did not have even one event when a sensor would not react when a door/window is open. So sensitivity and motion detection work exactly as it should I have also chimes enabled so I clearly hear one every time. 3. Batteries live long. they run on two cr2032 batteries and I did not had to chance them once yet in 2.5 years and in the app they still show as full. With such longevity it's really a great, healthy alternative to wires. 4. Simple but functional. You get full event history, possibility to align them with your Ring Alarm modes, chirp tones, simple toggle switch on/off for open and close alerts. 5. Decent glue & overall quality. Especially for my side door as it's glued on bare wood, despite being covered but still outside, exposed to wind and temperature swings - and still hangs there so far without issues. 6. Solid connection range. Again, mine is outside, quite far from the wifi and the base station and obviously with external walls in it's way and still works well and reliable even without the range extender that came together with the Ring alarm. Definitely solid for a small device without any hanging external antennas. Overall, small little sensor, that works reliably and long enough to not bother you with hunger for batteries. I can responsibly recommend it. Hope it helps, stay well and safe! Cheers

## Questions & Answers

**Q: How can I replace the defective sensor?**
A: Check battery.
Is it in warranty?
If all else fails, time for a new one.

**Q: Can this be linked to the outside ring floodlight siren? so if the contact breaks, the outdoor siren will go off?  thanks!**
A: not without the alarm system

**Q: Do these have a shock sensor, or just contact?**
A: There are two types of sensors. 
1. Contact, for doors and windows 
2. PIR for movement

**Q: Would this work ok on the INSIDE of a shed door?**
A: In principle there’s no reason why it won’t work in a shed, however you need to consider;

1.	It’s not intended for ‘out-door’ use, e.g. Temperature extremes and dampness.
2.	The two pieces of the sensor must remain with about half an inch of each other, else the sensor will trigger. This means your door / frame will need to be solid and not move about when closed.
3.	The distance from the shed/sensor to your alarm unit. There doesn’t seem to be much info about transmission range. So it depends how close your shed is.

This item, whilst more expensive would probably be a better choice;

as it’s intended for out-door use.

### ⭐⭐⭐⭐⭐ A good sensor for your Ring security system.
*by M***W on 6 March 2025*

Bought to monitor a access point door. It integrated with the existing Ring system really easily. It was just a matter of going into the Ring app and scanning the QR code to link the device to the existing hub. Then just remove the plastic which was stopping the battery from powering up the sensor. It was easy to fit into place. You just need to hold the sensor and contact in place for a couple of seconds to ensure it has stuck well to the surface. Also need to make sure the sensor and contact are not too far apart. So far the battery life seems to be quite good. The sensor has been installed for several months now and the battery still has plenty left. I did disable the light on the sensor within the Ring app which probably helps save a small amount of battery life as the little LED in the sensor doesn't light up. The signal from the sensor easily reaches the Ring hub which is probably 5 meters or so away and though a couple of walls. The hub reports the sensor signal as at maximum strength. It is quite expensive for a sensor, but then it is part of an investment into the whole Ring security system. It is also of a high quality of manufacture, and I haven't had any problem with any sensors I've installed so far. As you can see from the rest of the review, you do need a Ring hub for the sensor to connect to and install the Ring app to connect the device to the hub. Overall a good quality and reliable sensor with no false positives so far.
