Proximity Warn Away Sensor 

Additional sensor

The additional sensor or proximity sensor with warn away can be added to any of our alarm packages for an extra £50.00. This will give two zone protection. Zone 1 senses internal motion inside the vehicles cabin. Zone 2 senses motion just outside the vehicle, sensing motion on the front two doors just inside the wing mirrors


We have found the proximity and warn away sensor work on 80% of vehicles with no issues. However, some vehicles that are fitted with internal factory and aftermarket electrical wireless antennas can interfere with the sensor causing intermittent false alarms. Factory fitted DAB antennas, internet modems or dongles, security sensors, trackers and other aftermarket wireless devices including dash cams and trackers, can cause interference to the sensor causing Intermittent false alarms. or the sensor not to work at all. 

Tinted windows

Some vehicles fitted with window tints, security film or made of a certain protective material can block the signal of the additional sensor, stopping it from working all together, or making it hard to set up correctly. If you are having Tinted windows fitted as an aftermarket upgrade it is always worth checking if the tint is ceramic or metallic. Always opt for ceramic where possible.


Your installer will fit this sensor as an extra to your alarm if requested. If after the system is fitted and the sensor does false alarm or not function, it will need to be disabled in the smartphone app or removed completely. In some cases the false alarms are caused by the sensor being set too high and simply turning it down will stop most false alarms. However, It is advised that you do not buy this alarm system solely for this sensor as it may not work on your vehicle and may need the external zone disabling.

In the wireless world we live in, unfortunately a few things can interfere with the additional sensor outside the vehicle too. The worst cause of interference is long range home broadband. All it takes is for your neighbour to have it installed and that night, your prox will randomly false alarm.


There are a few other things which can interfere with the prox which you can check for. 


Metal objects placed in the centre console, like coins, keys or metallic objects.


Any wireless devices, for example iPod, iPhone, MP3 player with either wifi or Bluetooth switched on.


Leaving a mobile phone inside the car will false alarm the warn away too


Super fast powerful broadband routers near the vehicle as wifi routers interfere with them too. At my house the broadband router is just inside the front door. If I drive the car onto my drive forwards I get false alarms. But if I reverse it on it doesn't false alarm. 


Dash cams with motion park mode switch on


Some trackers work on the same frequency


9 times out of 10 it's something interfering with the prox which is inside or near the car. It's very rarely ever a faulty prox
