Best Garden Shed Alarm

The UK’s garden sheds are under threat from thieves – around 22,000 break-ins are reported every year and this figure is continuing to rise. In the UK, outbuildings such as sheds, playhouses, greenhouses and garages without any security measures are five times more likely to be broken into than those with: our garden sheds are regarded by thieves as an easy target – low-risk and easily accessible yet with the potential for crooks to make a tidy sum by the time they’ve sold on our power tools, bikes, golf clubs and BBQ!!!

The key to safe outdoor storage is to make your garden shed less desirable to opportunist thieves by improving the level of security. The best way of doing this is to install a shed alarm. As is the case with any kind of security measure, making your shed alarm visible is a deterrent in itself. No opportunist thief in their right mind is going to attempt to break into an outbuilding such as a shed, garage or playhouse when they can see security measures have been taken and the space is clearly alarmed: in most cases, especially when it comes to outdoor storage, the risk a potential intruder finds themselves faced with far outweighs the potential return.

Only got 5 minutes

Over the last few years, many areas of the country have experienced a series of simultaneous shed burglaries in which multiple home-owners in a certain area have been targeted, often more than once. Despite this worrying increase, many of us still “haven’t got round to” securing our outdoor storage areas. A simple yet effective, low-maintenance, relatively inexpensive solution is to invest in a shed alarm.

How to choose the best shed alarm

Whether you’re after a basic external siren alarm or high-tech motion detection, there’s a range of shed alarms available online to suit every budget, all of which offer various features and functions.

Wired Vs wireless

When choosing the best shed alarm system, you’ll have to decide whether you’re better suited to a wired or wireless device.

Wireless

Wireless alarms tend to be battery-powered and shouldn’t require professional installation. When the sensors on this type of alarm are triggered, you will be immediately notified via a visual and/or audio alert to your smartphone or landline. Some advanced systems can also be programmed to alert the police and/or designated security companies, although enabling this feature is likely to be subject to additional and/or subscription costs.

Wireless shed alarms are a popular choice when it comes to shed security as they’re easy to install (normally you just have to place them where you want them); low-maintenance, relatively inexpensive and there’s no trailing wires connecting the sensors, cameras and power source. A decent wireless shed alarm system will also allow you to monitor the activity in and around your shed from a remote location via your smartphone, tablet or laptop and adding additional sensors to a wireless system if far easier than trying on a wired one.

Wired

Although battery powered alarms are the most popular choice when it comes to securing your shed, there is still demand for alarm systems powered by the mains. Wired alarms use a network of wires to connect the sensors to a main control panel however the best wired shed alarms will also have an integrated back-up battery, which is designed to power the device in the event of a power-cut.

A wired shed alarm will normally need to be installed by a professional, which can prove costly. Once they’re up and running , you won’t have to keep replacing the batteries but the cost of installation can make quite a dent in your bank balance.

Why you need a shed alarm

Theft from garden buildings is on the rise. Thieves have cottoned on to the fact that us home owners focus the majority of our attention on protecting our homes and often choose to ignore the ‘sitting ducks’ that are our outdoor buildings despite the fact that our sheds, playhouses and garages are often used to store bulky items of value in order to increase living space and avoid clutter. The majority of sheds will come with a turn button or butterfly latch as standard, but these alone are unlikely to deter thieves from trying to gain entry; you’ll need to firstly invest in a heavy-duty padlock, or fit a key lock, and then it is strongly advised to invest in an alarm system. An exterior motion-sensor security light is also worth considering as these have proven to be an effective deterrent to thieves.

Even if you don’t have anything in your shed that you regard as being valuable, you should still install an alarm if there’s any tools or equipment in there, such as ladders, hammers or screwdrivers that an intruder could potentially use to break into your home once they’ve gained access to your shed.

Why your shed is so appealing to thieves

  • Shed’s are viewed as an easy target – without any security measures in place such as alarms, security lighting or CCTV, forcing entry is a simple exercise for an experienced thief
  • They’re often situated in locations away from the main residence, which reduces the risk of thieves being disturbed, and which offer a quick and easy escape route
  • There’s a good chance of a quick and high return –  lawn mowers, power tools, golf clubs, fishing equipment, mountain bikes – all belongings typically stored in a garden shed –  can be easily sold on with little chance of them being traced
  • Most courts will view breaking and entering into a shed as less serious than breaking into an occupied residence

If you have a shed in your garden, you should have it fitted with an alarm – it’s as simple as that. The primary reason for this being, to deter thieves from breaking-in and stealing the contents of your shed, whether this be power tools, garden furniture, bikes, golf clubs or gardening equipment, all of which are expensive to replace. Many insurance companies now stipulate minimum security measures which need to be in place on outbuildings in order for you to raise a claim in the case of a break-in and, if these security measures aren’t adhered to, you’re likely to find your claim is rejected and you’re left feeling red-faced, having to foot the bill in order to replace what was taken.

Alarming your shed on a budget 

There are a wide range of shed alarms available. Generally, the greater your budget, the more high-tech your alarm will be, but it is possible to pick up a decent alarm system without breaking the bank : the siren.

A siren alarm is the traditional alarm system and tends to be a combination of door and window switches, along with motion sensors. When an intruder is detected,  a loud siren is triggered to attract attention and frighten off intruders.

Installing a basic battery-operated, siren shed alarm is a quick and easy, inexpensive way to deter thieves and protect your shed and its contents from any light-fingered, uninvited visitors. They’re simple to install as the majority of alarms are free-standing and/or supplied with adjustable wall fixings. Once you’ve inserted the batteries into the alarm (usually 2-3 AAA batteries are required), you’re required to enter and set a 4-6 digit code or programme the remote(s). Once activated, the motion sensors should detect any movement and the siren will sound, attracting attention and disturbing the intruder. Upon entering, deactivating the alarm is simply done by keying in the code or by using the remote. 

Siren shed alarms are effective if your shed is in close proximity to your house and you spend a lot of time at home, or if there is likely to be people nearby to investigate the source of the alarm being triggered. However, if you live in a remote location, or have neighbours who can be a little temperamental, you may be best considering a wireless alarm system.

How shed alarms work

A shed alarm uses sensors to detect movement or recognise when entry is being made into a monitored area. The most common type of sensor consists of an electrical contact that triggers the alarm when broken. Some high-end models use more sophisticated technology such as PIR (passive infrared sensors) which detects infrared radiation.

What is PIR technology?

PIR detection technology has developed in recent years as manufacturers have found new and innovative ways to use passive infrared sensors to detect the presence of intruders.

Using infrared wavelengths, these motion-based detectors sense the infrared radiation that is radiated from all heat-emitting objects. Through the movement of these infrared wavelengths, these specialised sensors recognise the presence of people, animals and objects. The ‘passive’ reference refers to the fact that no heat or energy is emitted by the infrared sensor itself.

The best shed alarms which feature PIR sensors will have the option to notify you via your landline or smartphone in the event that the sensors detect an intruder, in addition to triggering the siren. This is particularly useful if your shed is an isolated or remote location.

Some models will also allow you to deactivate the siren feature so it doesn’t sound in the event of the alarm being raised but just sends you an inconspicuous alert! This is a useful feature for two reasons – firstly, if an intruder isn’t aware of the alarm, they won’t attempt to disable it, potentially damaging it in the process and also, providing you’re quick to react to the alert, you stand a better chance of catching the intruder in the act – particularly useful in areas where there has been a spate of burglaries.

Frequently Asked Questions

What safety precautions can I take to deter intruders?

In addition to alarming your shed, a heavy-duty padlock and stainless steel hasp along with good-quality door hinges should all make your garden shed less of a target. Motion-triggered security lighting and solid, secure fencing also serve as effective deterrents to intruders. However, even if you have all these measures in place, it’s still worth making sure that the contents of your shed are covered as part of your home contents insurance policy.

How do you activate/deactivate a shed alarm?

The best shed alarms will be battery-operated and supplied with a wireless remote control to activate and deactivate the device. This allows you to set or turn off the alarm prior to entering. The alternative to a remote is a pin system where you’re given a small amount of time to enter the pin code in order to deactivate the alarm.
