A shed or garage is the perfect storage place for garden tools, working equipment, and even bikes and motorbikes, all of which are expensive items to own. Therefore, it is a good idea to secure your valuables, and you can do this by fitting a secure padlock to your shed doors. But, if a thief has their heart set on parting you from your possessions, they are likely to be able to cut through a lock without too much trouble, and you may need a better deterrent such as a shed alarm system.

As a power source is not guaranteed in sheds or garages, the best shed alarms are powered by batteries, with the option to connect to a power source if one is available. But again, the best shed alarms will come with the batteries included, so that is something to look out for.

At least one remote control should also be included, and PIR sensors that have a good detection range. Other key features to look out for when installing a shed alarm are that it has a set security code, an adjustable wall mounting bracket if it is designed to be attached to a wall or door, and a loud siren.

To help you find the best shed alarm on the market, we have provided a top ten list of products and set out our buyer’s guide, providing advice and information on key features. We hope that this will help you to choose the best shed alarm suitable for your needs!

Shed Alarm Reviews

Tiiwee A1 Wireless Kit (Editor’s Choice)

Our editor’s choice award goes to the Tiiwee A1 Home Alarm system. It is a wireless solution powered by batteries and includes an alarm, two sensors, and remote control. The units take 2 AAA batteries each, and you can expect a four-month lifespan before the batteries will need replacing or recharging.

With a wireless solution, you are free to place the sensors where you choose and then move them if you decide on a different location, giving you complete control over the security system you put in place! It also means you are not left unprotected in the event of a power outage.

The alarm has a 120-decibel loud siren that will alert everyone around that there has been an intruder. Additionally, the sensor and alarm couldn’t be easier to install. You simply clean down the area you will install the sensor or alarm, peel off the adhesive strips, and stick the unit to the surface.

This is an extendable solution, where you can add additional motion sensors and remote controls, up to 40 sensors per alarm! This means you could have motion sensors on the fences or walls of your garden as well as on the shed itself. The alarm has four zones, and a light will indicate which of the zones has been triggered.

Finally, the shed alarm comes with a 12-month warranty if you are not happy with the solution.

Pros:

  • Flexible solution
  • Four zones
  • Loud siren at 120 decibel
  • Extendable
  • Easy to install and use

Cons:

  • The remote is very sensitive and easy to press accidentally
  • The sensors need repairing to the alarm when the batteries are changed
  • The plastic casing may be fragile

Yale YES-ALARMKIT Battery Powered (Luxury Choice)

This wireless system by Yale is easy to install and set up. It comes with the alarm, a PIR motion sensor, a door or window contact sensor, and an alarm keypad conveniently housed in a case so that the buttons cannot be accidentally pressed and the alarm triggered at an inconvenient time!

When activated, the shed alarm emits a 104-decibel siren, and you can configure a 20-second entry and exit time if required. Additionally, there are no contracts linked to this system, and you can add to it with more accessories over time if you want to add another PIR sensor, for instance.

The deluxe door alarm system comes with a 2-year guarantee for complete peace of mind when purchasing as this is a much more expensive option than some of the other alarm systems in our review.

Pros:

  • Easy to install and setup
  • Wireless installation
  • Long-lasting batteries
  • 2-year guarantee
  • A case for the keypad, so it is not accidentally pressed

Cons:

  • The sales material shows two sensors, but only one is supplied
  • The siren is not the loudest available, at only 104 decibels. It may not be loud enough for rural areas or large gardens
  • The programmer is also the keypad and doesn’t have a screen to review the settings

Yale SAA5015 Wireless Alarm (Best Value)

This is a less expensive alarm system offered by Yale. It is extremely easy to use and install and can be either stood up or attached to a wall or shed door using the hole on the unit. The alarm motion sensor is battery powered and takes 4 x AA batteries which are not included when you purchase the alarm.

The motion sensor alarm has a range of 12 m and will emit a loud alarm once triggered if a four-digit code is not entered on the unit within 10 seconds. The alarm is 100 decibels which are not as loud as some other shed alarm systems in our review, so it is worth reviewing whether that is sufficient for your sized garden or yard.

A light will appear on the shed alarm when the batteries are running low, so you will not find out one day that they have died without your knowledge.

Pros:

  • It has a battery indicator that notifies you when the battery is low
  • Easy to install
  • Four-digit code can be set to your preference
  • Can be left standing inside a shed or hung up on a wall or door
  • 12 m range

Cons:

  • The code can only be made up of 1, 2, 3 and 4
  • The alarm may not sound for long enough before shutting off
  • The delay between detecting motion and going off may give sufficient time for the unit to be broken by an intruder

CPVAN Motion Alarm (Best with PIR Sensor)

The CPVAN motion sensor alarm has a detection range of between 5 and 8 m, and it should be possible to hear the loud siren within a 100 m range! This makes it a perfect shed alarm system if you have a large outside area and the house is quite a distance away. In addition, the PIR sensor has a detection angle of 110°, so it will capture any movement in its range.

This is a free-standing battery-operated alarm unit that takes three AAA batteries to power it, which are included when you purchase. Screws or stickers are also included depending on where and how you wish to install the wireless shed alarm.

The remote control easily switches off the alarm and has a long range. It also has an SOS alarm button on the remote.

Pros:

  • It comes with a remote control that makes it easy to use
  • The detection range covers about 5-8 meters
  • Multipurpose installation options such as stand-alone unit
  • Batteries included
  • Installation kit included

Cons:

  • Heavy on battery power
  • May trigger false alarms due to sensitive motion detector
  • The link to attach the remote to a keyring may be flimsy

Defender Wireless Shed Alarm (Best with Keypad)

This Defender shed alarm is SBD certified, standing for Secured by Design, as police preferred specification product! It has two main ways to be triggered, by detecting vibration and if a door or window is opened, breaking the magnetic field of the alarm unit. The vibration trigger can be disabled if you only want to use it when a door or window is opened.

You can set a 30-second exit and a 5-second entry delay, and the loud siren is disabled by entering a four-digit code into the keypad. Additionally, it is straightforward to install, and it is supplied with the fixings required; you simply screw the keypad and motion detector to the window or door you wish to protect.

The alarm system requires three AAA batteries, but a solar panel is also supplied with your purchase to extend the lifespan of the batteries by up to 18 months.

One thing to note about the Defender Wireless Shed Alarm is that it is not suitable for installation outdoors and must be installed inside a shed or garage.

Pros:

  • The alarm comes with a keypad that allows you to register a pin of 4 digits
  • Vibration sensor or triggers when a door or window opens, breaking the magnet seal
  • Loud noise produced at 130 decibels
  • Solar panel included
  • Easy to install and fixings included

Cons:

  • The alarm is not suitable for external installation
  • The vibration sensor may be overly sensitive and triggers false alarms
  • It may not be easy to install and align the two parts on rough sawn wood

KERUI Wireless Security Burglar System (Best with Remote Control)

You certainly get a lot of product for your money when you purchase the KERUI security system, and it is further extendable if you decide to do that in the future. Included are a siren horn, two-door and window sensors, two remote controls, and a PIR motion sensor!

The included remote control can talk to the central alarm from a distance of 250 ft as long as it is unobstructed. There is also an SOS button on the remote control, which will immediately trigger the alarm. The alarm emits a 115 decibel loud sound when triggered, which is about mid-range in our review of alarm systems.

This shed and garage alarm comes with a fully programmed main unit which does not require any setup unless you want to reset it yourself. The siren is mains powered, the sensors are battery-powered, and the batteries are included when you purchase.

The sensors have a 0-8 m range and, depending on whether they are installed horizontally or vertically, have a detection arc of 110° or 60°, respectively.

Pros:

  • Two sensors, two remote controls, PIR motion detector, and alarm siren
  • Batteries included
  • 115-decibel siren
  • 8 m detection range
  • Comes fully programmed

Cons:

  • The cable from the siren horn may be too short of reaching to a powerpoint
  • The instructions may be too complex
  • The alarm may re-arm and therefore trigger when you are in the shed

Panamalar Door Window Sensor (Best WiFi)

This is not a security system like others in our review. Instead, it works by connecting the supplied motion sensor to the Smart Life app that you need to download for free; the WiFi-enabled sensor will then send an alert to the app on your phone when the door or window sensors are triggered.

This wireless shed and garage alert system is easily installed; you simply either stick or screw the door sensor in place with less than a 10 mm gap between the two parts and connect the sensor to the app.

If you have smart security lights on your garage or shed, you can integrate these to come on through the app as well. It is also Alexa and Google Home compatible, so you can ask them whether or not your shed door or window is secured!

This is not an audible siren alarm intended to deter thieves; it works by alerting you to any forced entry attempts to your shed or garage. If you want a system with alarm sounds, this may not be the product for you.

Pros:

  • Easily installed
  • The app will alert you if the batteries are running low
  • Inexpensive
  • Alexa and Google Home compatible
  • Wireless

Cons:

  • This is not an audible alarm, but rather you get an alert on your smartphone that a shed door or window has been opened
  • It will not work if your WiFi is down
  • The sensor may disconnect from the WiFi

TRIXES Garden Shed Wireless Motion Sensing (Best Battery Powered)

This is a very inexpensive alarm system, and all of the remote controls and door sensors come with the batteries included, making it even better value! The motion sensor alarm requires 4 x AA batteries which are not included.

The motion detector can be wall mounted with the kit supplied, and it has a 110° and 8 m detection range to detect movement. The two remote controls are supplied on keyrings and are extremely easy to use, with a simple button to arm and disarm the alarm system.

The siren is 105 decibels which are not the loudest in our review of best shed alarms, so it is important to check whether this will be loud enough for you to hear from your home.

Pros:

  • Adjustable wall mounting bracket
  • Two portable remote controls with batteries included
  • Easy to install
  • Inexpensive
  • Simple to operate with an arm and disarm button

Riswond Motion Sensor Alarm with Siren (Best Loud)

When triggered, the Riswond motion sensor has an impressive 125-decibel siren, making it one of the loudest shed alarms in our top ten. The motion sensor has an 8 m range and can detect movement within a 110° arc. Additionally, the alarm system uses the latest infrared sensor technology to detect human movement and interference to reduce the chance of a false alarm from happening.

The remote control has a 328 ft range from the door alarm and has a sliding cover to prevent you from accidentally arming or disarming the unit! Additionally, you can extend this security system by adding further remote controls and sensors.

The wireless alarm system is powered by three AAA batteries or the USB power lead, both of which are included.

Pros:

  • A USB power lead is included

The security system can detect motion from 6 m away, and the remotes can connect to the alarm from up to 100 m away when there are no obstructions. Additionally, the sound can be adjusted from high to low and set as a chime, alarm, or turn off.

Buyer’s Guide

Whether it is a motion sensor alarm for a garden or a shed alarm, they can come in a variety of different components, all working in slightly different ways. So we have set out some considerations and information for you below, which we hope will be helpful.

Wireless or a Wired Alarm?

Do you have a power source in your shed or garage, and do you want to either do the work yourself or pay an electrician to drill holes and install the alarm if you decide on a wired solution? If the answer is no to these questions, then a wireless garage alarm is probably the right option for you.

With a wireless solution, you are free to place the sensors where you choose and then move them if you decide on a different location, giving you complete control over the security system you put in place! It also means you are not left unprotected in the event of a power outage.

Key Features

There are a number of key features to look out for when selecting from the shed alarms available on the market.

PIR motion sensors are a sensitive and accurate way of detecting an intruder. Look for one that has a range of 8 m or even an alarm system that includes more than one sensor included in the package!

A delay for entry and exit to the shed or garage is also a useful feature. These can be set between 10 and up to 30 seconds. Some shed alarms may flash before the alarm triggers, giving away the alarm’s location, so this is something to look out for and consider before purchasing.

A remote control with a good range and a cover to prevent accidentally triggering your alarm is also a must!

One of our featured shed alarms connects to an app and will push an alert to your smartphone to make you aware of a break-in into your shed or garage. This may be suitable for you if you are in a built-up area and don’t wish to have all of your neighbours disturbed by a loud alarm, but it allows you to investigate or simply call the police without disturbing the thief.

Sound Level

This is probably one of the most important of the key features of an alarm. You need to know that it is loud enough to worry the intruder and at the same time alert you in your home and perhaps your neighbours as well to the break-in that is taking place.

All the alarms in our review have a decibel level over 100. The lowest is 104, and the highest is 130 decibels.

Taking into account how far away your shed or garage alarm is from your house and whether or not you have double glazing will give you an indication of the sound level you need from an alarm. You don’t want a thief to be able to laugh in the face of the sound being emitted!
