Intruder and Burglar Alarm
Proven Protection Backed by Over a Decade of Experience
At Securex, we’ve been installing reliable security systems for over 10 years. With successful installations behind us, we only choose proven, cost-effective, and industry-trusted systems — ensuring our clients get the best protection available
.
What a Typical Alarm Installation Includes:
External Siren mounted at the front of the property – provides a loud audible alert and acts as a strong visual deterrent with alternating lights
Opening Protection – sensors on doors and windows to detect unauthorized access
Penetration Detection – protection for key entry points or structural weaknesses
Motion Detection – internal sensors to identify movement within protected areas
We believe an alarm system should do more than just look the part — it should sound the alarm and act immediately. A dummy box or warning sign alone isn’t enough to stop intruders.
