Only the best shed alarms can be considered for ultimate safety. You might even think about the reason you need a shed alarm in the first place. But when you store expensive gardening tools and bikes in your shed, you need to properly protect your assets.

Theft is an issue that isn’t only limited house burglary. Your entire property can be under threat by those with bad intentions. Since many gangs of thieves know most sheds are unlocked, they can be interested in making a quick profit with minimum effort. But using some of the best shed alarms may limit and even deter their intentions. This article looks at some of your best options in the space.

    Yale SAA5015 Wireless Shed and Garage Alarm

This simple Yale wireless shed alarm is made to operate with precision. It works by using a motion detection sensor which offers reliability and that triggers a loud alarm. Facing an alarm system that triggers 100db of loud siren noise is something not many burglars want to deal with.

With a detection range of 12 meters, the alarm is among the most powerful in its class. It even allows you to set it up in a large garden where the shed is further away from the house and where your home alarm can’t reach.

Powered by batteries, this alarm doesn’t require a constant power source from your wall plug. You can simply change the batteries when needed.

PROS

Loud 100dB siren

Made with a freestanding design

Included red light indicator

CONS

Too large for some sheds

    Defender Wireless Shed Alarm

With a 4-digit code, the simple shed alarm is one of the compact designs you can choose. It represents a valuable solution to those who don’t like large alarms drawing attention to their shed. The alarm gets automatically triggered 15 seconds after the delay to enter the code.

But we also like it uses solar power so that you never have to swap out the batteries. With endless power, the alarm system runs itself with no user input. With a powerful 130db siren, the alarm might be small but it’s one of the loudest in its price range.

PROS

Made with glossy keypads

Loud 130dB alarm

Compact size

CONS

No motion sensor

    Trixes Garden Shed Wireless Motion-Sensing Alarm

With 2 remote controls, this alarms is practical and truly wireless. We like that it uses a different approach which means this alarm stops when you press the main button on the remote control. It skips the digit-based code enter so that you can control it from a distance.

The detection range of 8m allows the alarm to work at a high standard continuously. It represents one of the most reliable products in its class when it comes to the overall motion detection sensitivity, which is also adjustable.

PROS

Controlled by remote controls

Easy to mount

Loud 105dB alarm

CONS

Flimsy construction

    WER Wireless PIR Motion Sensor Alarm

The 105DB alarm has a 110° scanning area with an infrared PIR motion sensor. This motion detector allows it to work flawlessly in its detection efforts. There are 2 remote controls which can stop its alarm. You and your partner can each have a remote control for personal use.

With the help of an included mounting bracket, the sensor alarm is one of the most reliable when you think about its ease of installation. You might need professional installation for the alarm system in your home, but this WER PIR motion sensor alarm can be installed without any previous experience in this area.

    Kerui Standalone Home Shop Security

The Kerui security systems are our recommendation for large sheds. It stands out with its connectivity options as you can set it up with up to 40 wireless detectors and up to 10 remote controls. If you’re sharing your garden or living space with others, it can be just the system you need to make your lives easier.

With an alarm that sounds at 115db, this alarm system can be very loud, even if your garden is in the middle of the city. But it also comes with other advanced functions such as an SOS  panic button. This is the alarm system that you use when you need help. An elder person or children left alone at home can press this button on the remote control when they’re in danger and when there’s nobody around to help.

PROS

Compatible with 10 remote controls

Made with an SOS function

Loud 115dB alarm

    Tech Traders Wireless Pir Motion Sensor Alarm

With a large 110-degrees scanning area, this motion sensor alarm is among the best when it comes to your large garden. You can install it higher on your shed for it to cover a wide area easily. At the same time, you can use its 2 remote controls to fully control it from a distance.

It runs on 4 AA batteries which allow it to sound loud 105dB alarms. This system is also easily mountable with only a screwdriver. You just need to anchor the alarm on a wall mounting bracket yourself as the alarm is free-standing. However, you will need to buy the batteries as they’re not included in the pack.

    Lacoramo Door Alarm Sensor

With a loud 130dB alarm, the Lacoramo system is one of the easiest to use. It features 2 remote controls we highly appreciate. They come with large keys which let you select the type of action you want to undertake. This is why the alarm allows you to open it with a press of a button. You can also activate the alarm with a simple press of a button on the remote control.

But the remote control is also used to disarm or to arm the alarm. We like the overall simplicity of the remote control’s design which allow almost anyone to use such a best shed alarm at home without any specific training.

PROS

Made with modern remote controls

50-feet range

Included SOS mode

CONS

Batteries sold sepparately

    Kerui 11db Alarm

We like Kerui’s alarm mostly for its smart home chime integration. If you need to protect your shed as well as your home, you can consider the company’s products for sure. For example, the Kerui expandable alarm system comes with WiFi capabilities as you can connect it to a smart control host. You can also use it with smart doorbells and multiple other accessories which are controlled through a single hub.

This burglar security alarm system also comes with 2 small remote controls. They are smaller than other remote controls seen on similar alarms and you can carry them around as key chains. We recommend them for those who already carry too many keys around.

PROS

Made with arming and disarming buttons

Standalone alarm system

Compatible with 240V power

CONS

Extra remotes sold sepparately

    Uni-Com 65555 Garage and Shed Alarm

As one of the simplest garden and shed alarms, Uni-Com’s system comes with digital code access. It features a simple layout with multiple digits and an attachment which is placed on the shed’s door contact. You and possible burglars only have a few minutes to enter the code once the alarm is triggered. With a maximum alarm noise of 88dB, the garage and shed alarm is mainly recommended for small spaces. We recommend it for small garden sheds as a result.

PROS

Easy to use

Made with large keypads

Ideal for small sheds

CONS

Only sounds an 88dB alarm

How to choose the best shed alarms

Choosing the best shed alarms is not complicated. These alarms are very simple and they are only meant to protect the main door of the shed. However, not all garden alarms are the same and you might need to know what makes them truly great if you want a safe purchase.

Motion sensor detection range

The motion sensor detection range is one of the most important. You need to know that not every motion sensor is the same. Some have higher detection range while others only detect motion in their immediate vicinity. One of the issues to consider here is where you place your garden shed.

For a large garden, we recommend choosing a shed alarm that offers a large coverage area. This means a sensor which is capable of detecting any type of motion up to 12 meters away.

If, on the other hand, your garden is very small and your shed has limited space around it, you don’t need to invest in the highest capacity motion sensor. However, we still recommend an shed alarm system which detects all types of motion at least 8 meters away.

Some alarms come with no motion detection zones. They only activate when the garden shed door sensor opens by force or by key whenever the alarm code isn’t entered within a few seconds. We also recommend these alarms as they are low profile and loud, which can scare potential burglars away.

Decibels and alarm noise level

How loud should a shed alarm be? You selected garden shed alarm should have at least 90 decibels in sound level. On the other hand, some of the best shed alarms have a 110dB level which allows you to create your own safe space where the noise of the alarm is so loud burglars won’t be able to sit around in for more than a few seconds.

Remote controls

Using a remote control for typical alarm functions is crucial in the days of wireless smart homes. As much as possible, we recommend these solutions whenever you don’t want to go to the garden outbuilding to enter a 4-digit code manually in the eventually the burglar might still be around.

Most garden shed alarms that come with remote controls are now sold in packs. A minimum of 2 remote controls should be in one pack in case your lose 1 remote control. You might also want to keep your remote controls in different areas of the house just to avoid losing them together.

Digital access codes

Digital access codes can be short (typically 4 digits) or long (of around 6 digits). From a safety perspective, long alarm codes are the hardest to bypass. But since the alarm goes on the shed, even systems with 4-digit codes as some of those previously listed can work flawlessly in your garden shed. We recommend choosing an alarm system that combines both a physical access code with remote control operation as a more complex solution if you store valuables in your garden shed. They also offer a practical alternative to key fob alarms and to GSM alarms.

Ease of installation

How easy it is to install a shed alarm? It shouldn’t take more than 20-30 minutes to install this alarm system on your shed. You first need to read the user manual but most alarms are intuitive and you might as well DIY install them yourself without previous shed security systems experience.

You need to install the wall mount first. This is a plastic base attached with screws to the garden shed. The main alarm control panel is installed on this wall mount. Afterwards, you need to check the alarm yourself. You also need to ensure the security code works. If your alarm comes with remote controls, you need to check if the remote controls work as well.

Battery and power

The way you power your shed alarm is also important. You get to choose between battery operation and wall plug operation. If you need to add a power cable, you should hide it as much as possible so that burglars don’t cut it easily. But we highly recommend an alarm system that is battery-powered just to avoid such situations in the future. You also need to keep an eye on the battery life so that you aren’t left using an underpowered alarm system.

Shock sensors

Some garden shed alarms come with shock sensors. These sensors detect whenever someone tries to use force to break them. If burglars try to use a hammer or other tools to silence these alarms, they’ll only switch on the loud alarm themselves. At the same time, burglars might even want to try to remove the alarm from the wall completely and this is where the shock sensors activate to trigger the alarm.

Final considerations

Some of the best shed alarms are installed simply because of the easy access burglars can have to your garden. You might be sleeping in your bed when burglars could be looking through your garden for expensive tools and machines they can later sell for a profit.

A garden shed alarm kit can even sound like overthinking your safety. But it’s best to be safe than to be sorry. We recommend even using multiple garden shed alarms if you have a large shed similar to a garage with multiple doors and window sensors. You also need to add multiple alarm systems if you have multiple garden sheds.

Frequently Asked Questions


What is the best shed alarm?

We recommend the Yale SAA5015 Wireless Alarm Shed and Garage Alarm. It comes with 4-digit access codes and the reliability of its sensors is recognized by experts. Since it’s made by Yale, you also get a high-quality Amazon product that enjoys some of the best reviews both from regular users and from home security experts.

Will house alarm go off if the battery dies?

The house alarm doesn’t go off if the battery dies. However, it becomes useless as there’s no power. You can prevent this by ensuring your alarm system has a backup battery so that power is never truly out.

How long can a house alarm sound for?

A house alarm, as a garden shed alarm, can sound for a few minutes up to a few hours. You need to insert the code of the alarm yourself or you need to deactivate the alarm from the remote control if you want your alarm to switch off.

How loud is a burglar alarm?

A burglar alarm has a maximum noise between 80 and 135Db. The louder the alarm, the more improbable it is for a burglar to stick around for more than a few seconds. Since you can’t hear a normal conversation under such loud noise, most burglars are going to leave the premises.

Is it worth getting a shed alarm?

We recommend all of those interested in garden sheds to protect them properly. When you invest in machinery such as expensive lawnmowers and expensive power tools, you need to ensure they don’t attract the wrong kind of attention.

Unfortunately, we live in a society where break-in happens no matter how tough the laws get. There will always be those interested in stealing from others. Gardens tend to be the easiest prey for most thieves. They are easy to access and there’s nobody around during the night.

Of course, even alarm systems don’t guarantee thieves won’t be tempted to getting into your shed. But at least you know that the triggered alarm is so loud that it will wake up the entire neighbourhood and that those potentially interested in stealing from you will run away.

A good alarm system is also durable. You shouldn’t upgrade your shed’s alarm anytime soon. As a result, you get some of the best protection which lasts for years. It might be a small investment but it has the potential to protect all of your larger gardening tools investments.
