Very Reliable
So I now have four of these devices and two receives. You can programme teh receivers to respond to each of them with different tones and zones so you know what is being triggeredI haven't replace the batteries in two units for 3 years !!They are also easy to adjust for day/night sensitivity and rangeSimply the best

Great product.
This product is fantastic. The best around and worth the money. Installed one in the garden after a break in a couple of years ago. Just bought another for INSIDE a garage (away from the house). Wasn’t sure if it would detect but works perfectly. Very very happy.

I would like to be able to adjust the sensitivity
These are really well designed and work well. It drops a star because you can't adjust its sensitivity. Other adjustments yes but not that. I wanted to mount it to detect when someone comes into the drive or on foot and it does this perfectly but alas, crows and pidgeons walking also trigger it. The manufacturer recommends have 4 feet off the ground to avoid small animals triggering but that is not possible at the entrance to our drive.

Not Great
I bought this as a back up to my alarm and used in the garden. It was ok for a while then the receiver which is in the bedroom started making random noises so turned it off.

You can't put a price on security!
These are a great addition for anyone who is security conscious, whether it is for using at the home, work place or even camping.Highly recommend:1. Very easy to use, 2. Can be personalised with sounds and can work with/without batteries - so you have a back up power supply if the power goes down!Highly recommended! :)Thank you.

Essential piece of kit.
Great products. Been using for a few years now & couldn't be happier. Have a lot of security on our house & gotta say the gaurdline sensors give peace of mind, the first line of defence 🙂

Driveway Detection
I was/am fairly satisfied with Guardline system. That said, I’ve had intermittent issues over the last two weeks. It seemed to miss picking any movement up one day and then went to the extreme of going off every minute or so when it was windy for no apparent reason. It’s now back to sporadically detecting movement.The ball joint the sensor rotates on should be more solid. It moves far too easily and I’ve noticed the position changed on mine due to wind.

Excellent product it works perfectly just follow the instructions.
I have found that it will do what it says on the box.A wireless external siren would be a good idea
