Perimeter Security
That Works Completely
Off-Grid.
REMA Group supplies and installs fully wireless security beam systems across Pretoria and Gauteng. No Wi-Fi. No SIM card. No cables. Just reliable, independent perimeter protection for homes, businesses and farms.
Security That Doesn't
Depend on Anyone Else
Most security systems have a hidden weakness — they rely on your Wi-Fi, a SIM card or a physical cable to function. Cut the internet, lose signal, damage a cable and your system goes down. REMA Group's wireless security beam systems are completely independent.
Our perimeter beam systems operate on their own dedicated wireless frequency — completely separate from your home network, the cellular grid and any physical cable infrastructure. Loadshedding? Bad signal? Damaged cable? Your beams keep working.
We've been installing these systems for homes, businesses, farms and smallholdings across Pretoria and Gauteng since 2007, and our systems are specifically chosen for South Africa's unique challenges — remote properties, poor connectivity and unreliable power.
6 Reasons Our Systems
Outperform the Rest
Our wireless security beams solve the problems that traditional systems can't — especially in rural and farm environments.
No Wi-Fi Required
Our systems operate on their own dedicated wireless frequency — completely independent of your home or business internet connection.
No SIM Card Needed
No monthly data costs and no dependence on cellular coverage. This is critical for farms and rural properties where signal is unreliable.
No Cabling Required
No trenching, no conduit, no cable theft risk. Wireless installation is faster, cleaner and immune to the cable theft that cripples wired systems.
Loadshedding-Proof
Our systems include battery backup capability, so your security keeps working even during extended loadshedding — a critical feature in South Africa.
Farm & Rural Ready
Designed and tested specifically for large agricultural properties where Wi-Fi, cellular signal and cable infrastructure are unavailable or unreliable.
Professionally Installed
Every system is installed by our experienced team with proper positioning, testing and a walkthrough so you understand exactly how it works.
Security for Every Property
Our wireless beam systems are suited to any property — from a suburban home to a 500-hectare farm in Gauteng.
Farms & Smallholdings
The ideal solution for farms where Wi-Fi doesn't reach and cellular signal is weak. Our systems cover large perimeters without any connectivity dependency — exactly what rural Gauteng properties need.
Homes & Estates
Protect your family with a perimeter system that works independently from your internet and keeps running through loadshedding.
Businesses & Warehouses
Secure your perimeter without expensive cabling or ongoing data costs. Ideal for industrial sites and commercial properties across Pretoria.
Estates & Gated Communities
Supplement existing security with additional wireless beam perimeters on boundary walls and access points.
Game Farms & Lodges
Protect remote safari and game farm properties with robust, off-grid security that works in any environment.
From Assessment to
Active Protection
We follow a structured 4-step process to ensure every beam system is installed correctly and covers every vulnerable point.
Property Assessment
We survey your property to identify all vulnerable perimeter points, access gates and areas requiring beam coverage.
System Design & Quote
We design your custom beam layout and provide a transparent, itemised quote. You approve before we start.
Professional Installation
Beams are mounted, aligned and calibrated by our team — no drilling through walls, no cable trenching, clean and fast.
Testing & Handover
We test every beam path, verify alarm integration and walk you through the system so you're fully in control from day one.

Security Questions,
Answered.

Ask on WhatsAppHow exactly do the beams work without Wi-Fi or a SIM?
Our beam systems use dedicated short-range radio frequency (RF) communication between the transmitter and receiver units — completely separate from the internet, cellular networks and any other infrastructure. When a beam is broken, the signal triggers your alarm system directly via this RF link. No external network of any kind is required.
How many beams do I need for my property?
This depends entirely on your property's perimeter, the number of access points and what you want to protect. A standard residential property might need 4–8 beam pairs, while a farm could require 20–50+ units across a large perimeter. We conduct a free on-site assessment to determine exactly what's needed and provide a detailed quote.
Can the beams be triggered by animals or wind?
Our systems use multi-beam technology with intelligent filtering to dramatically reduce false alarms from small animals, birds or vegetation movement. Proper installation height and positioning also plays a key role — our team positions every beam to maximise detection while minimising false triggers. For farm environments, we use specific settings optimised for wildlife areas.
What happens to my system during loadshedding?
Our beam units can be configured with battery backup so they continue operating during loadshedding. Since the system doesn't rely on the internet or cellular network, it's far more resilient than Wi-Fi or SIM-based systems that go offline the moment power or signal is lost. We recommend battery backup as a standard part of any installation.
How much does wireless security beam installation cost?
Pricing depends on the number of beam pairs required, the size of your perimeter and any additional alarm integration needed. We offer free, no-obligation assessments and transparent quotes with no hidden costs. Contact us on WhatsApp with a description of your property and we'll give you a ballpark estimate immediately.
