Some of our most asked questions

An intruder alarm, also known as a burglar alarm, is designed to protect your property by sounding a loud siren when unauthorised motion or sound is detected when the property is unoccupied.

Our new branded wireless intruder alarms feature LED illumination for night-time functionality. In the event of an alarm, they alert nearby individuals with a low-power, high-performance piezo siren and a flashing strobe, providing both auditory and visual warnings simultaneously.

As a leading security company in the UK, W4G Fire & Security provides advanced intruder alarm systems designed with your safety in mind. With rising concerns about burglary and crime, we focus on delivering user-friendly systems that seamlessly integrate into your daily operations or work life.

Choosing our services offers a range of benefits, including:

  • Remote assistance: reliable remote support when you need it
  • App-based control: eliminate static guarding with customised, app-based access control
  • Sector adaptability: tailored solutions for various sectors
  • Integrated solutions: seamless integration with intruder alarms and monitored CCTV systems

Yes, and this is where modern security systems deliver their greatest value. A standalone intruder alarm will alert you to a breach, but when integrated with monitored CCTV and access control, your systems work together in real time. For example, when an alarm is triggered, your CCTV can automatically begin recording that zone, and your access control system can lock down entry points simultaneously.

At W4G Fire & Security, we design fully integrated security solutions tailored to your site. Whether you’re managing a single commercial premises or a multi-site operation, our engineers ensure each system communicates seamlessly. To understand how serious the cost of inadequate protection can be, take a look at our article on the 5 most expensive items ever stolen – real-world examples of what happens when security systems fail to work together.

Vacant and unoccupied properties are among the highest-risk sites for break-ins, vandalism, and unauthorised entry – particularly during evenings, weekends, and extended periods of closure. A professionally installed intruder alarm is one of the most effective deterrents available for these environments.

At W4G Fire & Security, our intruder alarm systems for vacant properties can be paired with 24/7 property alarm response and our property protection services to ensure a swift physical response when an alarm is triggered. For a broader look at how we protect unoccupied sites, read our guide on vacant property security solutions, which covers the full range of measures available beyond alarms alone.
