Garden sheds don’t have much protection and this is what makes them an easy target for criminals. However, by installing a shed alarm system (that you can install yourself), you can help protect it along with all of your valuable assets inside.

When compared to home alarm systems, shed alarms are very much a DIY installation. This is because most are wireless, which means that they are battery-powered with minimal components to install other than motion detection or door contact sensors.

To assist you in selecting the right alarm system for your garden shed, our handpicked selection lists top-performing systems, chosen based on our first-hand experience installing and using several different shed alarms. Our testing and up-to-date research further ensure the quality of our recommendations.

How The DIY Works Team Tests & Rates Shed Alarms

At our home, the office and a few rental properties we manage, there are sheds in the garden and each one we have protected with a dedicated shed alarm.

Therefore, to keep up our commitment to reviewing and testing the latest shed alarms (for this article), we’ve installed and tested multiple systems by top brands in the UK.

By far our favourite shed alarm is the Yale SAA5015 (as shown in the picture) and this is mainly due to how versatile it is and how easy it is to set up.

Although it’s relatively basic in design, it does the job of protecting sheds brilliantly.

As well as testing and our experience of installing multiple shed alarms, we also based our recommendations on the latest research and several factors.

1. Best Overall: Yale SAA5015 Wireless Shed Alarm

(How We Review →)

Yale is a highly reputable security brand and they produce a wide range of alarms but this particular model is designed for sheds, garages or other outbuildings. Depending on your shed setup, you can mount this model to the wall or position the alarm using the free-standing design and its completely wireless because it’s battery-powered.

Pros
  • Loud 100 dB siren
  • 12 metre motion detection range
  • Wall mounted or free=standing (we had it free-standing during our testing)
  • Low battery warning indicator
  • 4 digit pin code
  • Easy to install and use
Cons
  • We felt that it was very basic in terms of its functionality

To conclude, the Yale SAA5015 is a cost-effective shed alarm that’s developed by a reputable brand. Considering the low price tag, it also produces a very loud siren, which is perfect for sheds located further down the garden.

2. Best Value: Tech Traders Mini Wireless Shed Alarm

(How We Review →)

One of the cheapest shed alarms that’s actually worth buying is the Tech Traders Mini. It’s a wireless system that has a built-in PIR motion sensor that according to the brand can scan an area of 110 degrees.

Although it’s one of the cheapest systems, this alarm comes with two remote controls for easy activation of the alarm.

Pros
  • 105 dB siren
  • Entry and exit time delay
  • Integrated PIR motion sensor
  • Detection range of 8 metres
  • No wiring required
  • Supplied with mounting bracket
Cons
  • During testing, we felt that it went through batteries quite quickly (uses 4 x AA)

Overall, the Tech Traders Mini offers the best value for the money when compared to any of the alternatives. The only drawback is that it isn’t produced by a well-known security brand but this is reflected in the price.

3. Loudest Siren: Defender Redshield PIR Shed Alarm

(How We Review →)

If you require the loudest shed alarm system, the Defender Redshield is the best option because it produces an extremely loud 130 dB siren. However, as well as a loud siren, it also has other plus points such as a remote control.

According to the brand, they state that their shed alarm has been thoroughly tested and comes recommended by the UK police, councils and neighbourhood watch groups.

Pros
  • 130 dB siren output
  • Exit and entry delays
  • Supplied with wall mounting bracket
  • Remote control included
  • Easy to use and install
Cons
  • Relatively expensive when compared to the alterantives

If you require a reliable shed alarm that produces an extra loud siren, the Defender Redshield is perfect. It does come with a slightly more expensive price tag but it’s built to a high standard and the brand offers a money back guarantee too.

4. Best Expandable: KERUI DIY Wireless Security Alarm

(How We Review →)

The KERUI security system is an expandable option that’s available with a wide range of components. This is because according to the brand, it’s capable of supporting up to 30 wireless detectors, 8 remote controls, and 4 doorbell buttons.

Depending upon your requirements, the brand offers a wide range of kits to best suit your needs. These include basic and affordable kits to those that are designed for large garden sheds.

Pros
  • 115 dB siren output
  • Expandable system
  • Remote control included
  • Easy to install to any shed
Cons
  • Relatively expensive when compared to other shed alarms

Unlike any of the alternatives, this is an expandable shed alarm that you configure to meet your requirements. It’s also compatible with any KERUI branded products that work together without any complications.

5. Best 3G: UltraPIR GSM Alarm For Sheds

(How We Review →)

The UltraPIR GSM is a unique shed alarm that uses a 3G network signal to contact up to 3 key-holders if the alarm is compromised. It’ll also send a text message as a last resort in case neither of the three contacts picks up the phone.

Another standout feature of this kit is that it’ll also operate as a standard shed alarm that outputs an extra loud siren (130 dB). The system can also be expanded with additional sensors if required too.

Pros
  • 130 dB siren
  • Detection range of 10 metres
  • Includes a remote control
  • Uses a 3G network signal
  • Supplied with mounting bracket
Cons
  • Most expensive shed alarm within our roundup

Although the UltraPIR GSM comes with a premium price tag, it’s the best option for sheds located far away or at another location. It comes as a complete kit and can also be used in garages, caravans and elsewhere.

6. Best Budget: Friedland Response ML1 Shed Alarm

(How We Review →)

The Friedland Response ML1 is a basic shed alarm that’s keypad operated with a 20-second entry and exit delay. It’s also a pre-wired door contact alarm that takes just minutes to install with a user-friendly installation.

In terms of setting the system up, it has a 2.5-metre cable from the contacts to the controller, which allows you to mount the interface away from the shed door.

Pros
  • Tamper protection
  • Red light indicator
  • Panic alarm functionality
  • Delayed entry and exit
  • Easy DIY installation
Cons
  • Siren may not be loud enough for sheds far away (only 88 dB)

Overall, if you require a cheap and easy-to-install shed alarm, the Friedland Response ML1 system is ideal. However, if you store expensive items in the shed, the motion detection shed alarms may be the better option.

Conclusion

Considering that most people store a range of expensive assets within their shed such as a pressure washer, petrol lawn mower and so on, it’s certainly worth protecting it with a quality shed alarm system. Even if you go with a basic or cheap shed alarm, it’ll act as a deterrent to any potential criminals who are looking for an easy target.
