Home security is no longer optional—it’s a necessity. With South Africa’s high crime rates, protecting your property requires a reliable alarm system. But with so many options available, how do you choose between wireless and wired alarm systems?
In this guide, we’ll break down the pros, cons, costs, and best use cases for each type—helping you decide which system is right for your home.
1. Introduction: The Growing Need for Home Security in South Africa
According to recent crime statistics, burglaries and property crimes remain a major concern for South African homeowners. A robust alarm system is one of the most effective ways to deter intruders and alert you to potential threats.
But should you go for a traditional wired alarm or a modern wireless system like Kwêbeam? Let’s compare the two.

6. FAQs
❓ Can wireless alarms be hacked?
Kwêbeam uses 868MHz frequency(which is highly resistant to jamming) and together with continuous communication monitoring this threat is highly unlikely.
❓ Do wired alarms work during power outages?
Most have battery backups, but wireless beams (like Kwêbeam) keep working independently.
❓ How far can wireless beams communicate?
Kwêbeams repeater tech ensures coverage up to 100m+ per beam (expandable).
