Devtron’s livestreaming fence monitoring system giving peace of mind to a growing list of residential estates

In today’s security conscious world, one of the top priorities of residential estate living is ensuring that the electric fence is always operational, and an increasing number of estates are achieving that with Devtron’s Circuit Master solution.

Devtron is a leading supplier of a range of cutting-edge hardware and software solutions for the installation, monitoring and maintenance of residential and commercial security.  More than two dozen luxury and lifestyle estates and retirement villages rely on Devtron technology to secure their perimeter security.

Circuit Master is a cloud-based digital, livestreaming electric fence monitoring system that can be simultaneously viewed by multiple sites, including the control room, guards, security company and installers, with mobile functionality provided via the Devnet Mobile app.  Small estates without guard rooms are likewise able to use the system, with remote viewing by a single person.

At the heart of the system is the highly sophisticated and powerful, 3G Devnet24 modem.  Based on the same robust technology as used in the banking industry, it  collects all the perimeter and equipment data and makes it possible for anyone connected to use the  system to monitor and optimise the effectiveness of the fence on a round-the-clock basis. It has the ability to run the information over both local network or 3G cellular network.

One-stop solution

Matthew Krinsky, Devtron managing director, comments:  “Estate managers are in desperate need of constant and accurate information with regard to perimeter security.

“However, many estates use the products and services of any number of entities to provide them with this, from the fence installers, fibre network companies and local area network providers, to third party maintenance technicians,” he says.

“This means that when a problem occurs, it may take days to determine who is responsible for fixing the fault, during which time, estate security is vulnerable.  Of equal concern, is that it may take days before the estate manager is even aware that a fault has occurred, since there is no system that provides continuous monitoring of the integrity of all components on the fence.”

Circuit Master bypasses all role-players – consultants, technicians and fibre companies, so that the  estate only has to deal with a single company for the entire installation and ongoing support. Being a cloud-based solution, there are no delays while underground fibre network cables have to be fixed.  Installation is also simple, as the modem only has a tiny antenna and is stored in a compact kiosk, with one connection and a plug.

As Krinsky summarises, “It’s a full, standalone communications system with all the software stored in the modem and data disseminated through the cloud and stored under our watch.”

Three security layers for peace of mind

Estate managers can enjoy peace of mind knowing there are three layers of security:

The first is at the guardhouse, where the fence is actively monitored by guards.  A secondary, off-site layer is added where, for example, an estate security company, estate security manager or directors, fence Installers (if they so wish), as well as Devtron, which also monitors all of its customer sites 24X7, can view and react to faults.

In a third layer of security, all estates are provided with monthly audit reports on the overall integrity of the fence.  This information not only adds to their assurance that their estate perimeter is optimally secured, but the information is also useful for strategising over any future plans.

Devtron and Nemtek

Derius Wagner is regional manager in the Cape for Nemtek, one of South Africa’s leading suppliers of electric fencing products with a host of clients, both local and international.  Nemtek has a long-standing strategic partnership with Devtron, whose Circuit Master solution has enabled Nemtek to add substantial value to its customers as well as bring new ones on board.

“From our perspective as a manufacturer, the beauty of dealing with Devtron is that they do research and development, are highly flexible and can work with us to add value to our product.  For example, when we wanted to bring our D28 LCD high-security  electric fence energiser into the solution, they quickly incorporated it.”

What makes the relationship especially useful, says Wagner, is that Nemtek gains considerable trust  from being able to bring Krinsky, as the MD of Devtron, with them to speak directly with customers on site.

“It is so refreshing for our clients to have him on hand to explain anything, without having the need to be buffered to and fro while they try to get answers.”

These site visits also offer useful insight to Devtron, which continues to develop the Circuit Master solution and will soon begin launching it overseas.

Impressive list of estate clients

Devtron’s solution is currently installed at an impressive list of residential estates in the Cape region, and is starting to make inroads in Gauteng.  They include: Steenberg Wine Estate, De Zalze, Amdec Evergreen Retirement Villages, Leopard Creek, Blue Valley, Klein Bron, Arabella, The Oval and Century View.
