Enhancing estate security, the five-layer approach

Residential estates are designed to provide a serene and secure living environment enclosed within gated communities, offering residents peace of mind and an elevated standard of living. However, as crime evolves and security threats become more sophisticated, more than traditional security measures are required. This necessitates integrating advanced electronic security systems to bolster the safety and security of these estates.

Historically, residential security relied heavily on physical barriers such as walls, gates, and onsite security personnel. While these measures are still essential in South Africa, they are increasingly supplemented by highly advanced electronic security systems. Technological advances have paved the way for more efficient, reliable, and scalable security solutions that can proactively and systematically address a wide array of threats.

So, let us start at the first layer of electronic security systems, the access control system that is fundamental for managing and monitoring who enters and exits the estate.

Layers of access control

Modern systems can include a wide array of options like biometric scanners (such as fingerprint or facial recognition) and mobile-based access credentials, which have become an extremely popular way of gaining access by both residents and visitors alike since the COVID pandemic forced us all to go more ‘touchless’.

That leads us to visitor management software (VMS) that, over time, has become an integral part of any estate access control because it can do so much more, from pre-authorising visitors (by residents) to full-on property management via a dashboard and an application via the residents’ cell phones, making for seamless integration and interaction, all while protecting data, privacy and security. This first layer, paired with high-quality optical CCTV cameras and license plate recognition cameras, not only ensures a safe and secure entry point to an estate, but when done right, it also elevates the view that visitors and potential new homeowners will have of the level of security they can expect.

Contrary to what most might believe, the second layer is not the physical perimeter structure like walls, fencing, and electrified fencing but rather the perimeter surveillance cameras, specifically thermal cameras. These must be paired with advanced artificial intelligence (AI)-driven analytics to further enhance the effectiveness of surveillance and shoul be monitored either by an onsite or an offsite control room. But more on that later.

Physical perimeter security

And the third layer? Yes, the physical perimeter. Key to the success of the four-layer recipe is that the fence becomes what we call the second ‘tap’ on a perimeter security solution, the first ‘tap’ being the thermal camera analytic software that will warn of a problem before even reaching the fence/perimeter.

However, it is crucial that a physical barrier can delay a potential breach that might escalate quickly. Therefore, one must ensure that a physical barrier is further enhanced by a high-quality electrified fencing system that will not only deter, but also delay a potential threat or breach.

Onsite or offsite?

The fourth layer is guarding and offsite monitoring. Onsite and/or offsite video monitoring services provide an additional layer of security by ensuring that professional security personnel continuously monitor live surveillance footage. This deters potential intruders and ensures immediate response to any suspicious activity. In most cases, it is also advised that an offsite monitoring company is contracted, even if an onsite guarding complement is in place, for reasons, and to name but a few, guards can be ambushed by criminals or become incapacitated for various reasons.

Installing a ‘Deadman Switch’ - a button that must be pressed regularly within a preset time (incapacitated)—and/ or a panic button (ambushed or incapacitated) that can both raise an alarm, ensuring the appropriate course of action is taken.

The fifth and final layer is sometimes forgotten and/or neglected – System Maintenance. I have seen many state-of-the-art security solutions that are not properly and regularly maintained, from basics like regular calibration and optimisation of system and analytic software, to lack of vegetation clearing on the permitter fence line. Preventative maintenance will be key, not only in ensuring the system’s uptime, but also in ensuring the longevity of the original investment.

These five layers are the bare minimum that must be in place to ensure the 5 Ds of security are accomplished: Deter, Detect, Deny, Delay, and Defend.

In conclusion, the integration of electronic security systems in residential estates is no longer a luxury, but a necessity. These systems provide a robust and comprehensive approach to security, addressing modern threats and ensuring the safety and well-being of residents. By adopting advanced technologies and best practices, residential estates can create a secure and welcoming environment, offering peace of mind and an elevated standard of living. As technology continues to advance, staying abreast of the latest trends and innovations will be vital to maintaining and enhancing security in residential estates.
