Security Systems


With a proven pedigree in the digital security arena, Sigma Networks is the place to come to keep your organisation safe and secure. Our range of security systems can be ordered individually, or packaged together to give unrivalled protection.

Closed Circuit Television (CCTV)

The rapid convergence of many diverse technologies onto an IP platform has resulted in major changes to the CCTV industry. Long gone are the days of changing tapes in VCRs!

Sigma is at the forefront of this revolution, supplying and installing state-of-the-art IP-based CCTV systems that dovetail seamlessly into your existing IT network.

If that's a technological step too far for your organisation at this stage, why not consider a function-rich digital PC-based stand-alone system, or even a simple DVR set-up. Whatever you need, we can design, install and maintain a system that is perfect for you.

We offer a huge range of indoor, outdoor, infra-red, PTZ and covert camera options, so call now to find out how you're always in the picture with Sigma!

Access Control Systems

In these uncertain times, the security of your building and your staff must always be at the forefront of your mind.

Controlling and monitoring who gains access to your premises can greatly increase your peace of mind. From a single door entry system to a nationwide, multi-site campus solution, Sigma can offer a solution.

Keypads, proximity readers, even biometric door access; Sigma can supply, install and maintain a system that evolves with the changing needs of your organisation.

Call us now, and open the door to peace of mind!
