Advantages Of Wireless Intruder Alarms Vs Hard Wired Systems

Our intruder alarm systems use the latest technology movement detectors, magnetic contacts, break-glass / vibration detectors and infra-red beam detectors for flexibility and complete protection. Reliability is essential, that’s why all our systems are installed using a range of control panels and detection devices from leading manufacturers’ that are tried and tested solutions. Installed by our experienced engineers in accordance with the latest British and European Standards EN50131.

Easier and Faster Installation

Wireless systems don’t require running cables through walls, floors, or ceilings, which makes installation much quicker and less disruptive. Ideal for existing or finished buildings where rewiring would be costly or messy. In contrast, hard-wired systems usually require professional installation and significant labour.

Greater Flexibility and Portability

Wireless alarms are highly adaptable, sensors, detectors, and control panels can be repositioned or added easily. Perfect for tenants or people who move home, as the system can be uninstalled and relocated without damage. Hard-wired systems are typically fixed in place and difficult to move once installed.

Modern Connectivity and Integration

Many wireless alarms integrate with smart home systems, allowing remote monitoring and control through mobile apps. Users can receive real-time alerts via SMS, email, or push notifications. Hard-wired systems often require additional equipment for remote access or monitoring.

Minimal Disruption and Aesthetics

No need to drill or channel walls for cables, which maintains the property’s clean look and décor. Especially beneficial in heritage buildings or high-end interiors where preserving aesthetics matters.

Easier Upgrades and Expansion

Adding new sensors, cameras, or detectors is usually as simple as pairing new devices. Hard-wired systems may need extra cabling and rewiring, making upgrades more expensive and time-consuming.

Independent Power Supply

Wireless sensors are battery-powered, meaning they’ll still work during a mains power failure (provided the control unit has battery backup). Hard-wired systems rely more heavily on the main electrical supply.

Cost-Effective for Smaller Installations

For small premises or homes, wireless systems are generally cheaper overall when considering reduced installation and labour costs. Hard-wired systems might only become more cost-effective in large commercial installations where many sensors are required.

SS Systems project team have the expertise to plan, design and install both hardwired and wireless systems to suit your individual requirements in protecting your people, property, and assets. We specialise in wireless and hybrid systems, where minimal disruption to the building is important, such as heritage projects, industrial and commercial buildings. We are accredited by the SSAIB to design, install, commission and service all intruder systems.
