What is structured cabling and why does a business need it?
Structured cabling is a standardised system of cabling and associated hardware that provides a comprehensive telecommunications infrastructure for a building or campus. It supports multiple uses such as data, voice, video, and building management systems through a single, organised framework rather than separate, ad hoc cable runs for each system.
For a business, structured cabling means a cleaner, faster, and more manageable network. It reduces the time and cost of moves, additions, and changes, supports future technology upgrades without rewiring, and meets the performance standards required by manufacturers such as Molex, CommScope, and Telegärtner to qualify for an extended warranty on materials and workmanship. CNS designs and installs structured cabling systems for commercial estates, multi-tenant developments, and data-critical environments across South Africa.
What is blown fibre and when should a business use it instead of traditional fibre?
Blown fibre is a fibre optic installation method in which optical fibres are blown through pre-installed microducts using compressed air, rather than being pulled or pushed through conduit. The fibres are not installed until they are needed, which means the duct infrastructure is future-proof by design.
A business should consider blown fibre when planning an infrastructure that will need to scale. Because upgrading the fibre capacity requires only blowing new fibres through existing ducts rather than excavating or re-cabling, it dramatically reduces the long-term cost of bandwidth upgrades. It is particularly well suited to large commercial campuses, multi-building estates, and industrial sites where future expansion is likely. CNS installs blown fibre systems as part of its structured cabling and fibre service, and can assess whether the approach is appropriate for a specific site during the initial consultation.
What is the difference between IP CCTV and analogue CCTV?
IP CCTV transmits footage as digital data over a network connection, enabling remote access from any internet-connected device, higher resolution imaging, and integration with other IP-based systems such as access control and building management software. Analogue CCTV transmits a continuous video signal over coaxial cable to a local recording device and requires additional hardware for remote access.
For most commercial and industrial environments, IP CCTV is the preferred choice in 2026. It offers significantly higher resolution, smarter analytics including motion detection and thermal imaging, easier scalability, and the ability to monitor multiple sites from a single interface. CNS installs IP CCTV systems using Mobotix and Hikvision cameras, including Mobotix thermal radar technology that provides real-time 360-degree panoramic coverage for perimeter security. For clients not yet ready to replace existing analogue infrastructure, CNS can install IP-ready cabling that supports a future transition without full rewiring.
What does a UPS system do and why does a business network need one in South Africa?
A UPS (uninterruptible power supply) system provides emergency power to a load when the main power source fails. For a business network, this means servers, switches, routers, and other critical infrastructure remain operational during a power outage, protecting against data loss, hardware damage, and unplanned downtime.
In South Africa, a UPS system is not optional for any business that relies on network connectivity. Load shedding creates frequent, unpredictable power interruptions that can corrupt data, damage network hardware, and cause costly downtime. CNS installs APC UPS systems and energy management solutions specifically sized for network and data-critical environments, ensuring that infrastructure remains stable and protected throughout any interruption. For clients with larger energy requirements, CNS also provides broader energy management solutions as part of its turnkey infrastructure service.
What is a communication tower and what types of businesses need one?
A communication tower is a structure designed to support antennas and transmission equipment for wireless communications, including point-to-point microwave links, cellular signal distribution, and private wide-area networks. Towers range from rooftop mounts to full guyed or self-supporting structures depending on the application.
Businesses that typically require communication tower infrastructure include mining operations, agricultural estates, large industrial sites, game reserves, and any organisation that needs to connect multiple buildings or remote locations without relying on a public network provider. Government agencies and telecommunications companies also commission towers for signal coverage and backbone links. CNS designs, constructs, and commissions communication tower infrastructure using Ubiquiti-powered wireless backbone solutions, and manages the full project from structural design and regulatory approvals through to commissioning and ongoing support.
Can one company design and install our entire network infrastructure, or do we need multiple contractors?
Yes. CNS provides end-to-end turnkey infrastructure delivery as a single point of accountability. This means one company handles the initial site survey and needs assessment, infrastructure design, installation and cabling, systems integration, testing and commissioning, and ongoing maintenance and support under a service level agreement.
Using a single turnkey provider eliminates the coordination risk that comes from managing multiple contractors across a project. It also ensures that each element of the infrastructure is designed to work together rather than being installed in isolation by separate specialists. For large commercial or industrial projects, this single-accountability model reduces project timelines and provides a clear point of contact throughout. CNS has delivered turnkey network infrastructure projects for clients including MTN, ATTACQ, CMH Group, Solareff, and McDonald’s across South Africa since 1990.
What certifications should I look for when choosing a network infrastructure installer in South Africa?
When evaluating a network infrastructure installer in South Africa, look for manufacturer-level certifications from the OEM brands whose products will be installed in your building. These certifications confirm that the installer’s technicians have been trained to the manufacturer’s standards and that the installation will qualify for an extended product warranty.
The most significant certifications in the structured cabling and network infrastructure sector include Molex and CommScope certification for premise cabling, Telegärtner certification for high-performance cabling systems, and Mobotix and Hikvision certification for IP security and CCTV systems. Ubiquiti certification is relevant for wireless infrastructure. Additionally, look for ISO-compliant quality management processes, which indicate that the company’s systems and procedures meet a consistent standard regardless of project size. CNS holds accreditations across Molex, CommScope, Telegärtner, Mobotix, Hikvision, Ubiquiti, and APC, with ISO-compliant quality management across all installations.
