What are you keeping in your shed? We ask this because the contents of your shed may determine how much security you’ll want to protect it with. You don’t want your shed getting burgled regardless, of course, but it’s a sad fact that sheds are where many keep their tools.
Tools can fetch a good price and, when stored in sheds, can be taken without entering actual households, presenting minimal risk to wrongdoers. This means that sheds are often targeted by thieves, whether they have tools in or not.
Whether you’re storing workman tools, gardening implements, or bicycles, we have five alarms below that can help keep the contents of your sheds or garages safe and sound.
With each entry, we’ve detailed the advantages and disadvantages of each alarm model and have even gone as far as to write up a buyers’ guide so you can see how we’ve ranked those alarms.

How to find the best shed alarm
If you’re unfamiliar with security systems, and/or techy stuff in general, then it can be overwhelming to track down the right alarm for the shed or garage that you want to put it in. This buyers’ guide will explain the features many of the above alarms have, and how we used these properties to rank them like we did.
We separated these properties into four categories, those being the method of detection, the decibel level of the alarm siren, whether they’re wired or wireless, and the method of mounting and installation.
Method of Detection
To keep this short but simple, many alarm systems you’ll come across will operate via a PIR (Passive Infrared) sensor, which is a device that can be used to detect motion. This is favoured because it’s a sure-fire way of detecting someone entering places where they shouldn’t. It does this by detecting body heat, which is pretty much impossible for intruders to conceal, whilst not providing a false positive when something, say, falls over within sight of this alarm.
PIR sensors detect for around ten to fifteen metres, more than enough for many sheds, and they often need to be installed above two metres and at a 90-degree angle to work properly.
If you’re using other sensors connected to an alarm siren as part of a larger and more complicated alarm system, you can also get door and window sensors that are shock-activated. This means that they’ll add some extra protection by sounding off when your shed door or window gets forced open, adding some immediacy to the alarm response.
These sensors are often used in tandem with the PIR sensor capabilities of the main alarm component, however, and so we’d only recommend investing in a system with door sensors if your protected area is large enough to warrant this extra protection. They aren’t necessary by any means when you have a PIR sensor already in place, but more protection is always a nice thing to have.
Speaking of, once tripped, you want your alarm to have some kind of keypad-based security system. With these, you have a pin code that only you and other shed owners know, which gets used to disarm the alarm when it’s you that gets detected by the shed.
What good is a quiet alarm? The decibel reading of your alarm should be at 100dB at its lowest and about 130dB at its highest. You want your alarm to do two things, the first being to alert you and any others nearby that a crime is occurring. There is a second, and admittedly more entertaining, reason you might want to consider the decibel level of your alarm, too. That is to startle and cause discomfort in the intruder so that they flee your premises, and hopefully do so with ringing ears, which is best achieved by opting for the slightly higher decibel alarms like the 130dB ones.
Wired or Wireless
The difference between wired systems is that they have multiple sensors that are connected to the main siren box. This means that they tend to be more complicated to install, some even requiring professional installation, which makes them an unusual choice for shed alarms. That’s why fully-fledged alarm systems aren’t in the list above, and the one that does have multiple components has an easy installation process using adhesives and wireless sensors, anyway.
Wireless alarms are a much more common option for sheds since it’s simpler and doesn’t require much, if any, external sensors that aren’t part of the main box itself. These are battery-operated, so it’s simple to power and will retain that power should the mains power of your premises fail.
Method of Mounting
We mentioned above how our alarm option at number two uses adhesive strips to stick to walls, doors, and windows. The way you mount an alarm can change your experience with it. Some may require screwing or other heavy-duty means of installation, but these are usually exterior alarms that need to be hardier to withstand the elements.
Instead, look for interior alarms that are easier to mount and check their mounting requirements before you buy. Standard PIR-based alarms often require wall mounting, usually above two metres to work properly. Some alarms won’t even need wall mounting, instead, they’re able to have a freestanding setup where the box only needs to be positioned on a shelf.
