Why Outdoor Detection Always Beats Indoor Alarms

Many homeowners in Spain rely on outdated indoor alarm systems that only react after a burglar is already inside. That’s too late: windows are smashed, valuables stolen, and your safety compromised. Outdoor detection is the only true solution. It stops burglars before they reach your home with a blaring siren that sends them running. At Best Alarm System, we don’t sell cheap false security—we deliver Europe’s best protection that stops every break-in! Visit our homepage for an overview of our top-tier security solutions. In this article, we explain why indoor alarms are useless and why outdoor detection guarantees prevention.

What is Outdoor Detection?

Outdoor detection uses smart sensors to detect movement in your garden, on your terrace, or around your property. Radar or infrared sensors spot intruders the moment they step onto your premises. They trigger a 110-decibel outdoor siren and send an alert to your smartphone within 0.15 seconds. Indoor alarm systems wait until a door or window is forced—far too late. Outdoor detection repels burglars before they get near your home. Learn more about our sensors and how they work on our outdoor detection page.

The Failures of Indoor Alarm Systems

A traditional indoor alarm system relies on sensors like magnetic contacts, glass-break detectors, or motion sensors inside the home. These systems seem useful but fail miserably:

• Late detection: The alarm only triggers after the burglar is inside, leaving broken windows or doors in their wake.
• No prevention: Indoor alarms alert after a break-in but do nothing to stop it. Burglars grab valuables and flee before you react.
• Weak deterrence: An indoor siren is often inaudible outside, so neighbors don’t notice, and burglars carry on undisturbed.
• Unreliable monitoring centers: Many indoor alarms are tied to costly monitoring centers that rarely respond effectively. You’re lucky if they do anything during a break-in. Often, they only speak through a box in your living room, or they call you minutes later—if you miss the call, nothing happens. A signal jammer disables the monitoring center entirely, giving burglars all the time they need.

In Spain, where burglars always start by entering gardens or climbing onto balconies, waiting until someone is inside is a losing strategy.

The Advantages of Outdoor Detection

Outdoor detection is unbeatable, leaving indoor alarms in the dust:

• Rock-solid prevention: Outdoor sensors catch intruders in your garden or on your terrace long before they reach a door or window. No damage, no break-in—end of story.
• Unstoppable siren: A 110-decibel outdoor siren blasts the moment an intruder is detected. This noise scares burglars off instantly, and they always flee when the siren sounds. Unlike indoor sirens, the outdoor siren is clearly audible outside, alerting neighbors and increasing the chance of help. The only thing that drives burglars away is a lot of noise!
• No monitoring center, yet perfectly secure: Thanks to outdoor detection and the automatically triggered siren, burglars are always scared off by the noise, with no need for a monitoring center. Our systems also send alerts to your smartphone within 0.15 seconds via WiFi, GSM, or 4G, even if the internet is sabotaged, so you’re always in control.
• Jamming-proof: Burglars use signal jammers to block alarm signals. All traditional indoor alarm systems lack jamming detection, making them useless. We can disable any competing system with a simple, online-bought jammer, and we’ll prove it in a demonstration. Thousands of monthly Google searches for jammers show burglars actively use them. Our outdoor detection systems have jamming detection, spotting sabotage instantly and sending an alert, even when the alarm is off. Read more about this threat on our jamming dangers page.
• Unique technology: Our Hikvision AX PRO offers unmatched outdoor detection options, from curtain sensors to 120-degree radar, plus exclusive jamming detection. It’s outrageous that millions of Europeans pay monthly for systems a burglar can disable with a cheap jammer. No other system matches this combination of power and reliability.
• No false alarms: Smart sensors distinguish humans from pets, leaves, or wind, ensuring no unnecessary alerts. This makes outdoor detection more reliable than indoor motion sensors, which often trigger due to pets or drafts.
• Unrivaled flexibility: Outdoor sensors adapt to any home, from a villa with a large garden to an apartment with a balcony. They work in all weather conditions, have a battery life of 5+ years, and can be easily moved if you relocate.

Monitoring Centers: Why They’re Pointless

Many people ask if an alarm system without a monitoring center is effective. Here are the facts:

• No monitoring center needed: Thanks to outdoor detection and the automatically triggered siren, burglars are always scared off by the noise, without needing a monitoring center. Our systems also send instant alerts to your smartphone within 0.15 seconds, so you’re always informed, with no extra costs.
• No police response required: The siren ensures burglars flee within seconds, leaving no actual break-in to report. At most, someone takes a few steps in your garden, which isn’t a crime. This makes outdoor detection self-sufficient, eliminating the need for external intervention.
• Risks of monitoring centers: Don’t fall for insurers or companies pushing indoor alarms with monitoring center subscriptions. These systems are vulnerable to jammers, allowing everything to be stolen without you or the monitoring center noticing. If you file an insurance claim, it may be denied because the monitoring center recorded nothing—it looks like the alarm was off. Choose an insurer that doesn’t require alarms or monitoring centers. The premium discount for an alarm is negligible, often less than a euro monthly, and gives insurers an excuse to reject claims. Opt for freedom and security without extra conditions.
• Why waste €40-€60 monthly?: A monitoring center adds no security, only high costs. With outdoor detection, you get Europe’s best protection without subscription fees, and you’re always 100% secure. Check out our options on our installation packages page to see how affordable top quality is.

The Power of the Early Siren

The early outdoor siren is the heart of outdoor detection and a game-changing advantage:

• Instant deterrence: The moment an intruder steps onto your property, the sensor unleashes a 110-decibel siren—louder than a chainsaw and audible far beyond your home. Burglars flee within seconds, as we’ve seen dozens of times in customer videos, including one from a break-in attempt in Polop.
• No intervention needed: The siren automatically drives intruders away, without you lifting a finger. There’s no break-in to report, as the intruder is gone before any damage is done.
• More effective than indoor sirens: An indoor siren is often muffled and inaudible outside, letting burglars continue undisturbed. An outdoor siren alerts neighbors, passersby, and local security, increasing the chance of intervention.
• Proven results: Our customers regularly send videos of failed break-in attempts, with burglars fleeing the moment the siren sounds. In 100% of cases with outdoor detection, break-ins are prevented because intruders don’t stick around under a blaring siren. Watch our video of a real break-in attempt in Polop for proof.

A customer from Polop sent us a video via WhatsApp showing his security system in action. Without doing a thing, he watched on his camera as the burglar fled within seconds when the siren went off. “My home stayed untouched thanks to Best Alarm System!” he wrote enthusiastically.

Why Outdoor Cameras Without an Alarm System Don’t Work

Many people ask for an indoor alarm with outdoor cameras, assuming cameras provide enough security. This is a major misconception. Outdoor cameras without an outdoor alarm system offer zero protection against burglary:

• No prevention: Cameras only record footage, not stop burglars. Burglars often wave at cameras, not even bothering to cover their faces, knowing recordings trigger no immediate action.
• Verification only: Outdoor cameras are only useful as a verification tool with an outdoor alarm system. When the siren goes off, you can see the burglar fleeing on camera, confirming the attempt. Without a siren, cameras have no deterrent effect. Discover how our cameras work with outdoor detection on our outdoor detection page.
• Vulnerability: Burglars can ignore or sabotage cameras, especially without an alarm. An indoor alarm offers no support, as it only reacts once the burglar is inside.
• No substitute for outdoor detection: Only an outdoor alarm system with a 110-decibel siren ensures burglars flee. Cameras enhance this system by providing footage but are useless without the siren’s noise.

An indoor alarm with outdoor cameras is a half-baked solution. For real security, you need outdoor detection, with cameras as a backup.
