Intrusion alarm systems are essential components of modern security systems, designed to detect unauthorised access and protect both residential and commercial properties. These systems serve as a critical line of defence against theft, vandalism, and other security threats.
Whether you are safeguarding sensitive data in a data centre or protecting entry points in a home, choosing the right alarm system ensures optimal security and fewer false alarms. In this article, we explore the three main types of intrusion alarm systems, their features, components, and the benefits they offer in securing different types of premises.
1. Wired Intrusion Alarm Systems
Wired systems are traditional intrusion detection systems that rely on a physical network infrastructure of cables connecting sensors and devices to a central control panel. Wired intrusion alarm systems connect all components to the control panel through physical wiring. These systems are commonly used in commercial buildings and properties where permanent infrastructure is feasible.
Key Features of Wired Systems:
Wired systems are less prone to interference from wireless signals, making them ideal for sensitive environments like data centres and commercial spaces.
Once installed, wired intrusion alarms generally require less maintenance compared to wireless systems. Hardwired systems generally do not require batteries, resulting in lower long-term maintenance costs.
They provide a stable, hardwired connection, ensuring consistent communication between devices such as motion detectors, door and window sensors, contact switches, and glass-break sensors.
Hardwired intrusion alarm systems are considered to provide a higher level of security and are typically recommended for high-risk sites.
Limitations:
Wired systems require professional installation and may involve structural alterations, which can increase setup time and costs. Wired intrusion alarm systems typically require professional installation due to their complexity.
These systems are less adaptable when expanding or relocating components.
2. Wireless Intrusion Alarm Systems
Wireless systems offer flexible and cost-effective security solutions through smart home integration by eliminating the need for extensive cabling. These systems are ideal for residential properties, rental spaces, and sites where running wires is impractical.
Key Features of Wireless Systems:
Wireless intrusion alarms are quicker to install and can be moved or reconfigured with ease.
Many wireless systems are compatible with mobile devices, enabling remote monitoring and remote arming capabilities.
These systems are often more visually appealing due to the lack of visible wiring.
Wireless intruder alarm systems use radio or wireless frequencies to communicate between the control panel and sensors.
These systems utilise motion sensors, glass break sensors, infrared sensors, and contact sensors to detect movement and suspicious activity.
Wireless systems send alerts or alarms to connected devices, allowing rapid user response.
Limitations:
Wireless sensors rely on batteries, requiring regular checks and replacements, which may lead to higher maintenance costs over time.
Wireless signals can be disrupted by walls, appliances, or other electronic devices, leading to potential false alerts.
The effective range of wireless intrusion systems may be limited compared to wired systems.
3. Hybrid Intrusion Alarm Systems
Hybrid systems combine the best features of wired and wireless technologies, offering comprehensive protection as a versatile solution for complex security requirements. They are suitable for both commercial properties and large residential buildings that require layered protection.
Key Features of Hybrid Systems:
Hybrid systems allow you to connect wired components where possible and use wireless devices where cabling is not feasible.
These systems are easily expandable, making them ideal for growing businesses or multi-level buildings.
Hybrid systems combine both wired and wireless elements to balance reliability and ease of installation.
A single control panel manages both wired and wireless devices, offering complete control over the intrusion detection system.
Ideal for sites with mixed infrastructure or planned upgrades.
Limitations:
The advanced features and dual capability can lead to increased upfront investment.
Hybrid systems may require experienced security professionals for proper setup and optimisation.
Other Types and Monitoring Methods
Intrusion alarm systems can also be classified by how they are monitored:
Monitored Systems: These send alerts to a professional monitoring service for immediate response from security professionals or emergency services.
Unmonitored Systems: These trigger alarms or sirens directly on-site, relying on property owners or bystanders to respond.
Perimeter Sensor Systems: These extend protection around the entire property instead of just the building and are ideal for securing large outdoor areas.
Motion Detector Systems: These systems use infrared or ultrasonic sensors to detect movement within an area.
Each type of security alarm monitoring can be tailored to suit specific security needs and environments, offering combinations of features, flexibility, and protection.
Components of Intrusion Alarm Systems
An effective intrusion alarm system relies on several main components that detect and respond to unauthorised access:
Control Panel: Acts as the central hub, receiving input from sensors and triggering alarms.
Motion Sensors: Detect movement in monitored areas and trigger alerts.
Glass Break Sensors: Activate alarms when glass is shattered. Glass break sensors trigger an alarm when they detect vibrations from breaking glass.
Contact Sensors: Trigger alarms when doors or windows are opened or disturbed.
Alarm Indicators: Sirens and strobe lights alert occupants and deter intruders.
Monitoring Devices: Security cameras provide visual verification of triggered alarms.
Remote Access Devices: Allow users to monitor, arm, and disarm systems through mobile devices.
Benefits of Intrusion Alarm Systems
The installation of an intrusion alarm system provides numerous benefits:
Detects unauthorised access and monitors restricted zones.
Sends real-time alerts to connected devices.
Deters criminal activity and unwanted access.
Enables fast response through integration with monitoring services.
May reduce insurance premiums.
Prevents vandalism, loitering, and suspicious activity.
Enhances safety and peace of mind for occupants.
It can be integrated with smart home systems and fire safety measures.
Comparing Wired vs Wireless Systems
Making the right choice involves comparing wired, wireless, and the best intrusion detection system among the hybrid systems:
Installation: Wireless is DIY-friendly and quick to install, while wired requires professional setup.
Reliability: Wired systems are more stable and less susceptible to interference.
Maintenance: Wireless systems need battery changes. Wired systems have fewer long-term maintenance needs.
Flexibility: Wireless systems can be moved easily. Wired systems are fixed but reliable.
Aesthetics: Wireless systems avoid visible wiring and offer cleaner installation.
Range: Wired systems can handle longer distances. Wireless may be limited in large properties.
Power Supply: Modern wireless systems now come with backup power to maintain functionality during outages.
Popular Intrusion Alarm System Brands
Choosing a reliable brand helps ensure effective security and long-term performance:
Kisi: Introduced its intrusion detection system in 2021 to address flexibility and user experience.
SimpliSafe: Popular for cost-effective, high-performing wireless systems. Simplisafe’s technology has received many great reviews due to its inexpensive hardware and strong performance.
BOSCH: Offers robust products, though some reviews note a lack of innovation.
Honeywell: Provides versatile systems for homes and businesses.
ADT: Known for professional-grade security, with higher upfront costs.
Johnson Controls: Offers various solutions but may not specialise in intrusion alarms.
Integrating Access Control with Intrusion Alarms
Combining an access control system with intrusion detection enhances layered security:
Restricts access to sensitive areas.
Logs entry and exit activities.
Triggers alerts and system lockdowns when unauthorised access is attempted.
Ensures comprehensive coverage for high-risk environments.
Reducing False Alarms
False alarms can undermine the effectiveness of any system. Common causes include:
Improper sensor placement
Low battery levels
Environmental interference
Inadequate maintenance
Working with certified vendors ensures correct installation and calibration, helping reduce the risk of false alerts. Certified vendors should be used to ensure compliance with local regulations for alarm systems.
