Smart Alarm Systems & Perimeter Security
Stop Intruders Before They Enter Your Home
Your safety shouldn’t be reactive. At Home Security 1st, we specialize in “Early Detection” technology—securing your boundary line so you are alerted the moment a threat arrives, not after they are inside.
As Certified Paradox Installers and a PSIRA Registered company, we provide military-grade reliability for homes and businesses across the Western Cape.
Why Upgrade Your Alarm System With Us?
Old, faulty alarms are a risk you can’t afford. We replace outdated systems with smart, intuitive solutions that give you total control.

- Pet-Friendly Sensors: Advanced indoor passives that ignore your dogs and cats but catch intruders.
- Load Shedding Ready: High-capacity battery backups ensure your home stays armed even during Stage 6 power cuts.
- 24/7 Monitoring Options: We offer seamless linking to armed response, underwritten by ADT for rapid reaction times.
