Comparison
Wired vs Wireless Alarms
Choosing between wired and wireless alarms is one of the most common decisions for South African homeowners. Wired systems are robust with no detector batteries, while wireless systems install quickly with minimal disruption.
| Wired alarm system | Wireless alarm system | |
|---|---|---|
| Price | Lower hardware, higher labour | Higher hardware, lower labour |
| Installation | Cabling needed; more disruptive | Fast, minimal disruption |
| Reliability | No detector batteries; very stable | Reliable but battery-dependent; jam detection matters |
| Maintenance | Low; occasional panel battery | Periodic detector battery changes |
| Retrofit suitability | Harder in finished homes | Ideal for retrofits/finished homes |
| Scalability | Strong for large/commercial | Easy to add devices wirelessly |
| Best use case | New builds, large or commercial sites | Retrofits and homes wanting minimal cabling |
The verdict
Neither is universally better: wired alarms excel for new builds and battery-free reliability, while wireless alarms shine for retrofits and quick, tidy installs. Many modern systems are hybrid.
