Amazing product great for the shop perfect

These are great for keeping an eye out on things but it would have been really nice if the sensor triggered the sounder/lights unit differently each one a bit like zones. Instead the main sounder does the work between notifications and alarms with you having to switch the mode manuallyAs I say it does the job but could be better implemented

This is a two zone electronic trip wire for a very affordable price.You get 1 receiver and two infra red transmitter's that can be placed a considerable distance from the receiver.We have a decent sized garden with an old wooden shed at the furthest point from the house.Several of out neighbours have had their sheds broken into or heating oil syphoned from domestic tanks that like our shed is too far from the house to hear if someone is up to no good.Our shed contains an almost full set of wolf garden tools which has taken a good deal of time (and money) to collect for my garden obsessed partner, who would be devastated if they were taken.Unfortunately we have no electricity so far down the garden either so it is only recently that solar security lights have become powerful enough to be seen from the house or last all night.And even then you would only know someone was out there if you happened to look in the garden, which isn't likely in the middle of the night when thieves tend to do most of their work.This device needs 3 x AA batteries for the receiver which you can wall or desk mount in your home.Each of the PIR detectors need 3 x AAA batteries and can be discreetly hidden or put so high they cannot be reached.Now if someone is in our garden this marvellous little device will tell us, in our home without necessarily letting them know that we know they are there!So we can call the police while they are in the act!Of course we live in hope they will come and catch them!This set works well and was remarkably inexpensive at the time of review!Happy to help!
