Buyer’s guide

an old man testing out a shed alarm

Alternatives to Using a Shed Alarm

An alternative to using a shed alarm is the option of using a comprehensive security system that covers the entire property. This can include features such as outdoor cameras, motion sensors, door/window sensors, and a central control panel. By implementing a complete security system, you can ensure that your shed is protected as part of a larger network of security measures.

This approach allows for centralised monitoring and control, enabling you to receive real-time alerts, view live video feeds, and even integrate with smart home devices for added convenience. While shed alarms provide a focused solution for specific areas, a comprehensive security system offers a more robust and interconnected approach to safeguarding your entire property.

Key Features to Consider

When looking for the best shed alarm, there are several factors to consider. In this buying guide, we will discuss the essential features to help you make an informed decision.

Sensor Types: There are various types of sensors available in shed alarms. Some common ones are:

  • Motion sensors: These detect movement within a specified range.
  • Door/window sensors: These are triggered when a door or window is opened.
  • Glass break sensors: These detect the sound of breaking glass.

Consider the type of protection you require and choose the sensor type accordingly.

Range and Coverage: The range and coverage of a shed alarm are crucial. Ensure the alarm’s sensor can cover the entire area of your shed. Some alarms have expandable range capabilities, which can be advantageous if you need to increase coverage later.

Power Source: Shed alarms can be powered by batteries, solar panels, or mains electricity. Battery-powered models are easy to install and portable. Solar-powered alarms save on energy costs, but may require direct sunlight to charge. Mains electricity powered alarms provide consistent power but may require professional installation.

Alarm Sound: Consider the loudness (measured in decibels) of the alarm you choose. The higher the decibel level, the louder the alarm will be. A loud alarm is useful for notifying you or your neighbours of a security breach, but too loud may cause disturbance.

Ease of Installation: Look for a shed alarm that is simple to install. Many models can be set up without professional assistance. Choose a model with clear instructions and necessary mounting hardware included.

Budget: Shed alarms come in various price ranges. Determine your budget and find an alarm that offers the features you need at a price you can afford.

Remember to also factor in any ongoing costs, such as battery replacement or subscription fees for app-based monitoring services.

When selecting the best shed alarm for your needs, keep these factors in mind, and carefully consider which features are the most important to you.
