CarlockBT Vibration Sensor Add-on - Improved Car Theft Protection and Security for Your CarLock Device - Installs to Car Doors or Valuables for Instant Motion Detection (NOT for Standalone Use)

I have 4 sensors and found they work well. Cheap cost effective alarm of sorts.

Easy to set up and get working. Does the job very well. I am updating my review. The Tech support service from Carlock has been great. The low battery message on the sensor issue was resolved within a couple of days with a update to the app. It was simply a incorrect message tag so nothing wrong with the device. It is working flawlessly now. Carlock tech kept in constant email support and the issue was resolved promptly. Highly recommend!

Purchased this when it became available again to add to my existing Carlock setup.The app recognised it straight away, fitted as per the instructions, works well and a worthwhile addition to any Carlock setup.No problems with it going off when parked on busy roads, but does detect anything out of the ordinary and pushes a notification to the app no problem.

Didn’t work so sent it back

Small and discreet easy to fix almost anywhere in the car, fitted mine to the boot floor besides the spare wheel. Very sensitive and gives added protection from bumps when my car is unattended. Works really well and would recommend.

Very handy add on to the CarLock . GPS . Be mindful. Wear to put this . As you can get false alarms!! If the sensor is fitted to a panel or door. Just install on a panel where it will not vibrate to easy. I found this out . Even a lorry driving past can set this off. But good for security.

Bought the tracker which works brilliantly, but I wanted the vibration motion sensor to accompany the tracker, so it works along side it, and it does, the other day we had a loud thunder storm and the vibration set the tracker of telling me on my phone. I've also got the carlock tag when cu my daughter bought for me to work alongside the tracker and vibration sensor.

This is by far the most important thing I’ve purchased for my camper van. Whenever I now park up and go shopping whilst on the road, I can rest easy knowing my van is secure. To have a system that alerts you whenever your van is tampered with would previously of cost a packet so it was great to learn about the reasonably priced Carlock solution. I purchased these sensors to add to my system and they do exactly what they profess to do. Highly recommended if you value your vehicle. Just perfect, thanks Carlock.
