Each alarm panel is configured to display "Eagle All Security" so you always know who to call for support, upgrades, or maintenance. The Risk of Waiting ## 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. Our Process ## Five Steps to a Fully Protected Property 01 ### 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. 02 ### 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. 03 ### Professional Installation Our engineers install your alarm cleanly and efficiently. All sensors are positioned for maximum detection coverage with minimum false alarm risk. 04 ### 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. 05 ### 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. Benefits ## 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. Technical Detail ## 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. ### Related Services [Security System Installation](/services/security-system-installation) [CCTV Installation](/services/cctv-installation) [Door Entry Systems](/services/door-entry-systems) FAQ ## Intruder Alarm Questions Answered ### How much does an intruder alarm cost in London? ### How long does it take to install a burglar alarm? ### What's the difference between wired and wireless alarms? ### Will the alarm go off if my pets move around? ### Can I control the alarm from my phone? ### What happens during a power cut? ### Do you install alarms for commercial premises? ### What brands do you install? ### Can you upgrade my existing alarm system? ### Do you offer alarm monitoring services? ![Eagle All Security engineer installing CCTV camera on a London property](/assets/installer-selfie-DpP39Jss.jpg) ## Secure Your Property With a Reliable Alarm System Free site survey, fixed pricing, and installation within days.
