Most people rely on cameras for home or business security—but smart intruders know exactly where the blind spots are. Cameras help monitor activity, but they don’t physically stop anyone from entering your property.
So what actually keeps intruders out?
In this guide, we’ll compare two key perimeter security tools: fence alarm systems and security cameras. By the end, you’ll understand how to build a more effective, layered perimeter defense that fits your property’s needs.
1. What is perimeter security, and why does it matter?
Perimeter security refers to the first line of defense that surrounds your property: fences, gates, back entrances, garden paths, and detached storage areas. This outer layer determines whether your home or business is an easy target—or a well-protected fortress.
It's the part of your security setup that keeps intruders out before they even reach the front door. And while many homeowners and business owners focus on cameras, cameras don’t prevent entry—they just show you who got in.
That’s why layered security matters. The strongest perimeter defenses combine:
- Physical barriers (fences and gates)
- Detection systems (fence alarms)
- Visual surveillance (cameras)
- Access control (locks)
When integrated properly, these components work together to stop, detect, and respond to threats more effectively than any one solution on its own.
2. Why fence alarm systems offer superior detection
Fence alarms detect physical interactions with the fence itself: cutting, climbing, or shaking. Unlike cameras, they don’t rely on lighting or visual lines of sight. This makes them highly reliable—even in low-light, poor weather, or remote locations where cameras might underperform.
Key benefits:
- Full perimeter coverage: Fence sensors cover the entire boundary—no blind spots.
- Real-time detection: Intrusions are detected the moment they happen.
- Weather-resistant and durable: Ideal for outdoor environments where cameras might fail.
- Low maintenance and cost-effective: Fewer technical issues and lower total cost of ownership.
- Harder to disable: Often hidden and tamper-resistant, making them less vulnerable to sabotage.
These advantages make fence alarm systems especially effective in high-risk environments, large properties, and rural areas.
Pair with: Borg Gate Locks for secure, weatherproof access to garden gates, rear entry points, or service paths. These mechanical locks don’t require keys or batteries, making them ideal for high-use gates and environments where electronic access systems may not be practical.
3. Where security cameras shine—and where they don’t
Security cameras offer sophisticated monitoring features, but they can’t cover everything alone. Strengths:
- Smart analytics: Detect motion, facial recognition, or loitering.
- Visual evidence: Useful for verifying alarms and aiding investigations.
- Remote access: Monitor live feeds from your phone or computer.
However, despite their capabilities, cameras have some clear limitations:
- Blind spots: One camera can’t cover all angles—you’ll need multiple to secure a full perimeter.
- Weather-dependent: Fog, rain, or direct sunlight can interfere with footage.
- Maintenance-heavy: Requires power, storage, regular cleaning, and occasional troubleshooting.
They also don’t physically prevent access, meaning that without locks or other deterrents, a determined intruder may still gain entry.
Pair with: ABUS Padlocks to secure gates, storage units, and tool sheds. Use cameras to monitor these high-risk entry points and record any tampering or forced entry for evidence and insurance claims.
4. Why locks still matter—even in smart homes
Think of locks as your last line of defense. Cameras might alert you to suspicious behaviour, but only a strong lock can physically stop an intruder from entering.
- Built with hardened steel for superior cut resistance
- Ideal for use on outdoor gates, sheds, or external storage
- Available in weatherproof options for long-term outdoor exposure
- Mechanical, code-based locks (no keys to lose or batteries to change)
- Excellent for outdoor gates or access paths that need daily entry
- Designed for longevity and reliability in outdoor conditions
Even in high-tech homes, old-fashioned physical security still matters. It buys you time and protects your most vulnerable points of entry. If someone tampers with a lock, it may deter them entirely—or at least slow them down long enough for an alarm to be triggered.
5. The power of integration: fences + cameras + locks
When you combine fence alarms, cameras, and physical locks, you create a multi-layered defense system that protects against a wide range of threats.
Benefits of integration:
- Layered defense: Fences deter, alarms detect, cameras verify, and locks delay or deny access.
- Automated response: Fence alarms can trigger cameras to record, lights to turn on, or phone alerts to send.
- More accurate monitoring: Visual verification reduces false alarms and wasted responses.
- Psychological deterrence: A visible combo of fencing, secure locks, and cameras creates a strong sense of risk for intruders.
- Remote monitoring: Many systems today allow full control and monitoring via mobile apps or centralized control centers.
This comprehensive approach is used by both homeowners and businesses to maximize deterrence, speed up response times, and improve situational awareness.
6. Which setup is right for you?
Your security setup should reflect your property’s size, location, and risk profile. Here's a quick guide:
|
Property Type |
Recommended Setup |
|
Small Home or Townhouse |
ABUS padlock + basic camera for shed/back gate |
|
Large Home or Estate |
Fence alarms + Borg gate locks + smart cameras |
|
Business Property |
Integrated perimeter system with remote monitoring & layered physical protection |
|
Rural or Harsh Climate |
Fence sensors + weatherproof mechanical locks (like Borg) |
No matter your setup, it’s important to walk your perimeter and evaluate it from an outsider’s perspective. Ask: If I were trying to break in, where would I start? Then reinforce those exact points with detection and delay mechanisms.
If you're relying on cameras alone, you're leaving gaps.
- Fence alarm systems offer better coverage and earlier detection.
- Security cameras provide verification and evidence—but can be circumvented.
- Locks are still your most reliable barrier to entry.
The best perimeter security strategy isn’t either/or. It’s all of the above. When used together, fence alarms, cameras, and durable locks provide layered protection that adapts to both residential and commercial needs.
