6 Best Shed Alarms for your garden

It’s a shame that we are searching for the best shed alarms but I’m afraid thats the reality of the times we find ourselves in. You’re probably just securing a cordless lawn mower, a hedge trimmer, and your grass trimmers as well as a whole host of tools. In a perfect world we wouldn’t need a shed alarm but seeing as we do I have put together a list of the best shed alarms based on ability to detect an intruder, how well the batteries last, the noise output, and from my personal perspective, a shed alarm should not throw out false positives. The last thing you want is to wake up in the middle of the night because the cat set the shed alarm off!
