![]() ![]() ![]() PIR alarms are probably the most popular type of shed and garage alarm available. Often called PIR (Passive Infa-Red) alarms, these security systems work by detecting movement in their field of view using variations in infa-red body heat. And then after one false alarm too many, you'll decrease the sensitivity too much and they won't go off when you are actually being robbed! You're likely to make them too sensitive initially and experience lots of false alarms. So the thief might be scared off before they do too much damage.Īnd also before they see the treasures you're keeping in your shed (and decide it might be worth coming back later)!īut the difficulty of getting the sensitivity settings right makes me a bit wary about recommending this type of alarm in sheds or garages. One advantage of these types of alarms is that they're likely to detect a break in before the thief actually gets inside the shed or garage. And you obviously don't want to make it too insensitive, as that could result in an undetected break in! You can usually adjust the sensitiveness to avoid bad weather or animals setting the alarm off unnecessarily. But also the roof or walls of your shed.Īnd if someone tries to break in, the vibrations that they cause will set the alarm off. So again, they could be attached to shed doors or widows. These alarms are triggered by movement in whatever they're attached to. The main disadvantage is that they won't go off if the thief comes in through the roof. So there's no chance of an animal, weather conditions, or other types of disruption setting them off. A door or window is only likely to be opened by a person. ![]() The advantage of this type of shed alarm is that it's a very specific trigger. When the door or window is opened, that contact is broken and if the alarm isn't deactivated the siren will go off. And the other part is attached next to the first but on the frame.Īlthough they're not touching they're close enough to form a magnetic contact between them. One part is attached to the shed door (or window). These sensors typically consist of two parts. And this comes down to what sort of sensor it uses. The first thing to decide is: how your shed alarm should detect a break in. What type of sensor is best for your shed alarm? But to find the right one for your space there's a couple of things you need to think about. I'm pretty sure there's a suitable alarm system for every shed (or garage). How to choose a shed or garage alarm system And if it alerts you too, you can do something about it!įor these reasons I think that a shed or garage alarm can be another useful layer of security in a many layered set up.Īnd besides, (as we'll see) they're so easy to set up and some of them are so cheap these days, that there's no reason not to give them a go. So, while for sure: not every neighbor will come running when an alarm goes off, the noise itself will be enough to scare off many thieves. I couldn't find any academic studies that concentrate on shed or garage alarms specifically, but I think the principal should be the same.Īnecdotally, I have also heard stories of bike thieves fleeing when a garage or shed alarm has been triggered. ![]()
