JC Window/Door Vibration Glass Break Vibration Sensor Wireless 433MHz for Home Business Security Alarm Systems

I have a few of these now connected to a different manufacturer alarm system, easy WiFi connection easy setup small so not obtrusive. Had no faults and they work really well so much so will order some more to cover all exposed areas very good

Installed this RF vibration sensor with a Sonoff bridge out of sight on my trailer at a distance of 50m away. The bridge is indoors so does have a wall to get through and triggers the alarm when interfered with. To make the sensor weatherproof I sealed it inside a small polybag. No telling how long the battery lasts so not a true evaluation as of yet.

I had no problems sniffing the code for this using a Raspberry Pi. This means that I can integrate it in with my existing 433MHz sensors that I have working with Home Assistant.Sensitivity seems OK. If I bang on the conservatory window, and the one next to it, then the sensor will trigger. Guessing that a burglar would use more force, and so this would trigger for windows further away too.Having bought additional sensors after the first one, the good news is that the codes on each sensor are unique. This means that the Pi can distinguish which sensor has been triggered, so that when I get an alert to my phone, it tells me exactly which sensor has been triggered.However, the transmission range of these sensors is poorer than the Lloytron MIP sensors that I also use. So there were some places in the house where a Lloytron MIP sensor worked fine, but the signal was not received from one of these JC glass break sensors. This was resolved by adding another RXB6 433MHz receiver to a different Raspberry Pi, closer to the sensors that were not being received by the original Pi. Having done this, all the sensors now work fine.

Keeps disconnecting from alarm and fell off window

Compatible with the Tuya alarm system, which is what I was looking for, once activated I only had to press the add sensor button in the tuya app on my phone and it was added to the system. Very convenient and just what I needed and was looking for.

easy to install and hook up...

do as they say in advert very good

Very pleased with these sensors. One is sensitive enough to protect the whole area of my French Doors, any intruder trying to break in will trigger the alarm. Will order more as soon as stocks available.

Costa poco e a distanza di quasi sei mesi ancora vanno benissimo

Ajouté a l'alarme owsoo cs118 sans problème reconnu premier coup .

So I really really wanted to love this sensor. It is nice looking, has good range and it's sensitivity seems about how you would want it. So far so good, right? And had I written the review back then, it would have gotten 5 stars. But here is the thing, when this sensor had low battery condition I got no warning. Instead it just started firing off false alarms. Alarm after alarm after alarm. Not a great way to find out about a low battery, especially if it starts in the middle of the night.Darn it, is all I have to say. This happened after about 5 months of use. I suppose one could just change the battery every 3 months or so but that's sort of a pain.I may try it again with a new battery but I just so hate false alarms.UPDATE: I replaced the battery and the device was dead. I contacted the seller and they shipped me out a new one to try. Know that the replacement process was very slow with multiple emails sent to get this done but the seller eventually did come through. So I am back using this and will update the review if the same low battery issue arises with the new one. I have updated the review to 4 stars given that the seller ultimately did come through, although I had wished it had been a bit more responsive.

Detector no demasiado pequeño. Lo he colocado en un ventanal grande que tengo y si le das un golpe al cristal lo detecta. Creo que es un poco más sensible de la cuenta y no sé si saltará con facilidad.
