Reliable Intruder Alarms
That Stop Break-Ins
Before They Happen
Professionally installed burglar alarm systems with smartphone alerts, pet-immune sensors, and a 12-month guarantee. Deterrence that works — installed within days across London.
Alarm Systems Built to Deter, Detect, and Alert
An intruder alarm is your property's active defence. Unlike passive measures like locks and bolts, an alarm system actively detects unauthorised entry and responds immediately — triggering a loud siren, alerting you via smartphone, and creating a hostile environment for intruders. Learn more about alarm installation costs in London.
We install wired and wireless burglar alarm systems for homes, flats, shops, offices, and warehouses across London and the Home Counties. Every system is designed around your property's specific layout, entry points, and risk profile — not pulled from a standard package.
For complete protection, combine your alarm with CCTV installation and door entry systems. Layered security deters criminals at every stage — from approach to entry attempt. From the initial site survey to final handover, you deal directly with our installation team.
Signs Your Property Needs Protection
Real Alarm Systems We've Installed
Modern Control Panels With App Integration
Every alarm system we install includes a modern LCD control panel with intuitive operation. Arm and disarm using codes, fobs, or your smartphone app. Each panel is branded with "Eagle All Security" for ongoing support identification.
Sensors, Bell Boxes & Complete Protection
From pet-immune PIR motion sensors to tamper-proof external bell boxes, every component is professionally mounted and tested. Our branded bell boxes act as a powerful visual deterrent — criminals know this property is protected.
Installed by Our Expert Engineers
Our team handles every installation from start to finish — no subcontractors. Each alarm panel is configured to display "Eagle All Security" so you always know who to call for support, upgrades, or maintenance.
Every Day Without an Alarm Is a Day You're Exposed
London has one of the highest burglary rates in the UK. Properties without visible alarm systems are significantly more likely to be targeted.
No Deterrent, No Warning
Without a visible alarm box and sensor network, there's nothing to make a burglar think twice. Your property looks exactly like every other unprotected target on the street.
Delayed Response
Without instant alerts, a break-in could go unnoticed for hours. The longer it takes to respond, the more damage is done and the less likely anything is recovered.
Insurance Complications
Many insurance policies require a working intruder alarm. Without one, you may face higher premiums, reduced payouts, or rejected claims entirely.
Five Steps to a Fully Protected Property
Free Site Survey
We inspect every entry point, assess your property's risk profile, and identify the optimal alarm configuration — at no cost and with no obligation.
System Recommendation
Based on the survey, we recommend a wired or wireless alarm system tailored to your property. You receive a fixed quote covering all equipment, labour, and setup.
Professional Installation
Our engineers install your alarm cleanly and efficiently. All sensors are positioned for maximum detection coverage with minimum false alarm risk.
Full System Test
Every zone is tested individually and as a complete system. Walk tests confirm PIR coverage, and entry/exit routes are verified for correct timing.
Handover + App Setup
We walk you through the control panel, set up smartphone notifications, configure user codes, and explain your 12-month parts and labour guarantee.
What You Get With Every Alarm Installation
Immediate Intruder Deterrent
A visible alarm bell box and interior siren are proven to deter opportunistic burglars. Most intruders move on when they see an active alarm system.
Smartphone Alerts
Receive instant push notifications the moment your alarm is triggered. Know exactly which zone has been activated, even when you're hundreds of miles away.
Rapid Installation
Most residential alarm systems are installed and fully operational within a single day. Commercial systems typically take 1–2 days depending on zone count.
Insurance Compliance
A professionally installed intruder alarm meets UK insurance requirements and can reduce your premiums by up to 20%. We provide installation certificates.
Pet-Immune Sensors
Our PIR sensors are configured with pet immunity, allowing pets up to 25kg to move freely without triggering false alarms.
Wireless or Wired Options
Choose the system that fits your property. Wireless for minimal disruption, wired for maximum reliability — or a hybrid combining both.
Alarm System Types, Components & Technology
Wired Alarm Systems
Wired intruder alarms connect each sensor directly to the control panel via physical cabling. They're the gold standard for reliability — no batteries to maintain, no wireless interference, and consistent performance over decades. Ideal for new builds, renovations, and commercial premises where long-term stability is the priority.
Wireless Alarm Systems
Wireless alarms use encrypted radio signals to communicate between sensors and the control panel. They're significantly faster to install, require no chasing cables into walls, and are ideal for existing properties and listed buildings. Modern wireless systems from Ajax and Texecom use military-grade encryption and offer battery life of 3–7 years per sensor.
Hybrid Systems
Hybrid systems combine wired and wireless components. This is particularly useful when extending an existing wired system — new zones can be added wirelessly without the cost and disruption of running additional cables.
PIR Sensors & Detection
Passive infrared (PIR) sensors detect changes in heat patterns caused by human movement. We use dual-element and quad-element sensors for higher accuracy and lower false alarm rates. Pet-immune models allow animals up to 25kg to move freely. Curtain PIRs provide narrow detection beams for window protection.
Bell Boxes & Sirens
Every installation includes a tamper-proof external bell box — the single most visible deterrent against break-ins. Internal sirens produce 110dB+ to disorient intruders and alert neighbours. Strobe lighting adds additional visual deterrence.
Smartphone & App Integration
All modern systems we install include app-based control via iOS and Android. Arm, disarm, check status, and receive zone-specific alerts in real time. Some systems also integrate with voice assistants and smart home platforms.
Commercial Alarm Features
Commercial intruder alarms offer multi-user access codes, zone partitioning for multi-tenant buildings, time-scheduled arming, and integration with CCTV and access control systems. We install commercial alarms for retail units, offices, warehouses, and construction sites across North London.
