Wireless Intruder Alarms for Businesses in the UK

Empty buildings, sites without power or properties in remote areas face higher risks of break-ins, squatters, arson and theft. But knowing how to protect them, or how to stop trespassers after an incident, can feel overwhelming.

Wireless intruder alarms solve that problem. Clearway installs wireless intruder alarms that detect motion and breaches, providing 24/7 monitoring for properties without mains power. Wireless intruder alarms are security systems that use battery-powered sensors to detect motion, heat, smoke, and perimeter breaches, transmitting alerts via secure radio frequencies to monitoring centres.

No need for mains power: Commercial Wireless Alarms

Alarm systems are a vital component of security for both commercial and residential premises. However, this poses a complication for commercial sites in remote locations, without mains power, or where development works render hardwired alarms redundant on a short-term basis. 

Our commercial wireless alarm systems are faultlessly reliable and can be used for residential and commercial properties (whether occupied, vacant, or void), as well as multiple sites. They are compatible with access control networks and CCTV surveillance systems.

Key Benefits of Wireless Intruder Alarms

  • Fast, flexible installation without mains power
  • Reliable 24/7 protection via tamper-proof batteries
  • Wide-area coverage of up to one km
  • Integrated monitoring through our NSI Gold centre
  • Compatible with access controls and CCTV 
  • Instant detection of motion, perimeter and entry breaches
  • Available for temporary and long-term requirements
  • Cost-effective, scalable and redeployable across sites

Our Wireless Intruder Alarm Options

As a leading UK security provider, Clearway recognises that every property and site poses different challenges – we cannot take a one-size-fits-all approach. We adapt our security and monitoring services to any number of unique premises, with some of the most popular services including the following.

Wireless Intruder Alarm Design

As a leading security provider specialising in preventative alarm systems and secure property management, Clearway designs, commissions and fits all types of intruder alarms adapted to your individual requirements.

We project manage your security alarm upgrade at every step, with services including:

  • Tailored alarm system design
  • Full on-site risk assessments
  • Installation, including mains power connections and civil works
  • Commissioning components and hardware
  • Providing routine servicing and maintenance
  • 24/7 emergency callouts

If you need support with alarm placement or designing an intruder alarm system to cover all potential entrance points and risks, please get in touch to schedule a no-obligation consultation at your convenience.

High Specification Alarms

Every premise, site, building and business has varying risks, operational hours, entrance points and security priorities.

Our role, as your security partner, is to recommend the right features and functions that will enhance your existing protocols and enable you to manage your alarm security seamlessly.

Example features available within a wireless intruder alarm system include:

  • Multi-area or zone coverage
  • Automated user logging
  • Remote monitoring access
  • Rapid response police liaison
  • On and off-site system control
  • Video alarm verification
  • Proximity token technology
  • Complete system integration
  • Grade Two alarm networks

High-specification wireless alarms can incorporate alarm verification, whereby your security device records a snippet of video to identify the cause of the alarm signal.

Off-site control enables you to review alarm status, access your user logs, and arm or disarm alarms as needed, whether on-site or remotely via a secure device from another location.

Please get in touch if you would like further advice about the appropriate features and technical specifications to tailor your wireless intruder alarms to your business or site.

Intruder Alarm Maintenance

Clearway offers customised alarm maintenance and inspections tailored to the specific implementation and usage context of your alarm system. For instance, a wireless alarm system in a secure vacant property may experience fewer issues compared to one installed in a high-traffic, publicly accessible area. Our approach considers each use case to determine the most suitable frequency for monitoring and inspections.

As a standard recommendation, we suggest monthly alarm servicing, supported by an annual thorough assessment of your alarm system’s needs, should your property remain vacant. We also test and maintain fire alarms on the premises.

Alarm Maintenance Services

Alarm Receiving and Monitoring

All Clearway commercial alarm systems can be connected to our industry-accredited NSI Gold Cat II Alarm Receiving Centre, providing a cost-effective way to rely on professional alarm responders to manage security alerts, dispatch emergency responders, or follow your security protocols as required.

We monitor all alarm, fire, smoke, intruder and surveillance systems, receiving and evaluating alerts from Digicoms, Dualcoms and Redcare networks, along with lone worker and IP intruder alarms.

Our nationwide alarm monitoring station is accredited to BS 5979: Cat II ARC and BS 8418: CCTV Systems, and carries an NSI Gold certification for Fire, Intruder, and Personal Attack Devices.

Our dedicated team of responders work quickly and effectively, with extensive training in security responses, alarm verification and your specific building management requirements.

Clearway incorporates cutting-edge signalling technology and data transmissions through a secure wireless data network, ensuring that any alarm activation is immediately relayed to the appropriate personnel and a response is initiated.

As an insurance-approved installer, we also provide GPRS signalling equipment suited to residential or business premises, with installations carried out by our trained engineers.

    How Wireless Intruder Alarms Work in Practice

    Get A Quote

    How Wireless Intruder Alarms Work in Practice

    1. Creating a Visible Deterrent:

    Installing cameras, signage, and other security measures acts as a strong preventative, showing prospective intruders or squatters that a construction site or empty unit is not vulnerable to perimeter breaches.

    2. Capturing Varied Alarms and Triggers:

    Using secure, tamper-proof batteries means that your alarms remain on high alert, 24/7, and all year-round, and any issues, from smoke and heat to movement or motion over your perimeter, will be detected.

    3. Circulating Alerts to Trained Responders:

    Advanced sensors ensure that, whatever the scenario and however remote the property, if any unauthorised entry is attempted, your wireless intruder alarm will be instantly activated and the appropriate response initiated.

    4. Ongoing Monitoring 24/7/365:

    Keeping a continual watch over your alarm system is essential, and our responders log and investigate every alarm, standing down false alerts and ensuring your site is always being supervised.

    How Does Wireless Intruder Alarm Installation Work?

    1. Window and Door-Open Sensors:

    Sensors can be positioned on any access point or vulnerabilities, from doors and windows or roller shutters and emergency exits that intruders could attempt to bypass.

    2. Heat and Smoke Detection:

    Optional environmental sensors act as a dual-purpose security system, picking up on signs of heat and smoke that indicate a potential fire emergency.

    3. Perimeter Monitoring:

    Wide-scope, reliable tracking can detect motion and movement, whether a person or vehicle, even at a distance, providing continual coverage of your site boundaries.

    4. Secure Alarm Transmissions:

    Our wireless alarm devices circulate notifications immediately to our response team and other relevant parties, with signals that cannot be intercepted or diverted.

    Key Problems Wireless Intruder Alarms Resolve

    There are numerous scenarios where mains electricity is either unavailable, prohibitively costly to connect to, or where power supplies are unreliable – making a wireless, autonomous alarm system a vital safeguard against a diverse range of threats and risks.

    1. Your Property Needs Protection, But Has No Mains Power or Cabling Access

    You may own, supervise, or manage an empty residential rental unit, a commercial premise, a development site, or an agricultural facility that requires dependable alarm coverage without access to mains electricity or cables.

    2. You’re Managing Development or Renovation Work, Which Means Hardwired Alarms Aren’t Viable

    Your construction or redevelopment project carries the usual risks of intrusions, health and safety threats, and targeted thefts of materials and tools. You need a wire-free solution to ensure the site is properly protected.

    3. You Require Temporary or Remote Monitoring During Construction or Property Vacancies

    You have a short-term increase in risk and want to mitigate the likelihood of an incident, but only need alarms temporarily while construction work is in progress or until the property is newly tenanted.

    4. You’re Responsible for Multiple or Dispersed Sites That Need Easy-to-Install Alarm Coverage

    You have a complex, large compound, organisation, or construction project that covers a wide area with multiple units, entry points, zones, and buildings – all of which require ongoing alarm coverage within one remotely accessible system.

    5. You’ve Had False Alarms, Poor Reliability or Tampering Issues With Older Systems

    You need to replace outdated alarms which are prone to outages, update security systems that have been bypassed by intruders, or eliminate the nuisance and cost of frequent false alarm callouts.

    6. You Need an Alarm Solution That Is Insurance Compliant and Can Integrate With CCTV or Access Controls

    You’re being pressured to improve site-wide or property security to meet the terms of your insurance coverage, and you need an alarm solution that works alongside CCTV surveillance cameras and access control systems.

    For advice and support on the best security solutions for your locations, please give our team a call, and we will be delighted to provide our recommendations.

    What Do Our Security Experts Say?

    Our UK Sales Director, Kelvin Danton, explains why alarms are so important.

    Wireless alarms are enormously helpful for vacant property owners and construction businesses – but their flawless dependability, speed, and ease of installation, along with the confidence of knowing you have continual monitoring, have a much broader range of use cases.

    If you have concerns about the costs of hardwiring alarms, integrating motion detectors with CCTV, or covering extended perimeters within your budget, a wireless intruder alarm system could be the answer you’re looking for.

    A Successful Project

    We were approached to assist with a security issue at a vacant commercial property in Bath city centre. With shorter daylight hours during winter the client wanted to ensure their asset was effectively protected. The brief was to reinstate the intruder alarm and connect it to our NSI Gold II Alarm Receiving Centre (ARC).

    Frequently Asked Questions

    Got a question about our site security? Read our frequently asked questions.

    What Is the Difference Between a Wireless and Hardwired Alarm?

    As the name suggests, the primary contrast is that hardwired alarms are permanently fixed and connect with your mains power supply, and often with WiFi signalling.

    For any site where this isn’t possible, electricity supplies are exposed to outages, or where temporary coverage is needed, a wireless alarm is a preferable option and can be fitted without the need for cables or wiring.

    How Long Do Wireless Alarm Batteries Last?

    Commercial-quality, long-life alarm batteries can last for several years, depending on the frequency of activation. Most tamper-proof battery packs are designed to maintain 100% performance for up to three or five years. We can recommend the best options depending on how long you anticipate needing wireless intruder alarms.

    Can the System Connect to CCTV or Access Controls?

    Of course! Intruder detection services encompass a wide range of applications, utilising numerous potential detectors, sensors, and systems to prevent and mitigate the impact of criminal activity.

    Many clients opt for a bespoke intruder detection approach, combining cameras and security alarms in different zones, depending on the risk level associated with each area of the premises.

    Related services that work perfectly in conjunction with a wireless intruder alarm include:

    • Visually Verified Alarms: These alarms are ideal for properties with a high incidence of false alarms, preventing costs and time wasted on unnecessary callouts. Conversely, when the alert is authentic, the monitoring team can quickly identify the nature and location of the security breach, allowing them to direct a targeted response.
    • Anti-Theft Fog Systems: often used in high-value targets or business-critical spaces, an anti-theft fog system fills the specific area with dense, low-visibility smoke. While non-toxic and safe to breathe, unlawful intruders are forced to retreat, with the fog remaining for up to an hour while security personnel or emergency services arrive.
    • Fixed Intruder Alarms: high-performance intruder alarms form an essential component of a robust security approach. We design, install, and maintain a wide range of alarm systems, with each network tailored to meet your specific security requirements.
    • Wireless Intrusion Detection System: Deter crime and anti-social activity with the inView Detect wireless intrusion detection system – the latest, rapidly deployable, cutting-edge, portable protection device.

    Please contact us if you require any additional information about our intruder detection services.

    Can I Move or Reuse the System Across Different Sites?

    Absolutely! Wireless alarms are scalable and portable, which means you can position the alarms or sensors as work phases change, or update areas requiring coverage as some parts of a compound or development are brought back into use.

    What Maintenance or Servicing Is Required?

    The regularity and amount of maintenance needed will vary based on whether you’re using wireless intruder alarms for a short-term period or on a longer basis. However, we usually recommend monthly servicing to verify that alarms and sensors remain in optimal condition, alongside full annual maintenance visits.

    Is Monitoring Available 24/7 Through Your ARC?

    Yes – Clearway’s ARC is operational every hour of every day, on every day of the year. Whether an intruder alarm sounds during working hours, over a holiday period, or during the night, a responder will be on hand to take the appropriate action.

    How Reliable Is a Wireless Intruder Alarm?

    Our wireless alarms are extremely reliable and utilise secure transmissions to ensure that alerts cannot be compromised by interference.

    Can I Use Wireless Intruder Alarms on a Residential Property?

    Absolutely – a discreet wireless alarm system is quick and simple to install and can be used on residential or commercial properties to guard against various potential threats whilst providing a very cost-effective and robust security solution.
