One of RA & A ’ s latest projects is the oppointment by Tongaat Hulett to develop a security master plan for all public spaces in the Sibaya Coastal Precinct , which is a mixed-use development on Durban ’ s North Coast . They were also tasked with writing a security protocol for the overall development which ensures that there is a coordinated response from all the developers to whom Tongaat Hulett sold the serviced land . Included in these documents was a plan for Crime Prevention through Environmental Design ( CPTED ), which aims to deter crime through strategies − such as natural surveillance , access control and territorial reinforcement − that rely on influencing offender decisions preceding criminal acts .
One of the key ingredients to securing the perimeter and the most costly security measure for any development is fencing . In most cases an electric fence is the chosen solution , but unfortunately maintenance is expensive and the false alarm rate is also high . From a financing perspective , Rob identifies the length of the boundary fence versus the number of stands to be sold as an important factor in securing any built environment . “ If the price of a stand needs to subsidise an excessive fence at today ’ s costs , plus surveillance , it becomes very difficult to keep costs down .”
He explains that the number of access points in secure estates also directly impacts the developer ’ s overheads as staffing multiple entrances is an expensive exercise .
“ There needs to be a security manpower plan from the outset . A well-designed control point , manned correctly , always saves money in the operational phase .”
In RA & A ’ s view , the most successful estates , in terms of their security track record , had all formed a subcommittee representing both developers and residents from an early stage . “ Together they are able to fine-tune their security solution and take joint ownership to the advantage of everyone .”
Fibre technology is used extensively in the security industry , and RA & A consults for many developers , such as Tongaat Hulett , looking to offer fibre to the home ( FTTH ) as a valuable add-on to the land infrastructure . “ Moving into fibre was a natural progression for our business .” RA & A ’ s involvement in fibre installation is at an advisory level , assisting clients to find a suitable model for their particular environment and how the service should be financed .
The company often reminds developers of the value of owning their passive network – in other words , the fibre itself or an open access network , either of which gives developers the freedom to choose their own internet service provider .
“ We ’ ve just finished renegotiations to run the network for Kindlewood Estate , another Tongaat Hulett development , and they have benefited from more leverage as proprietors of their network .”
What is the future of running security systems as web services over open networks .? Rob is concerned about this approach . There is a need for two separate networks , one or more for security services and another for FTTH . He warns that the use of a centralised security network can make the entire system vulnerable to attack .
Rob acknowledges the ways in which technological advancement is making our built environments safer , but stresses the need to realise the limits of technology and rely more on human co-operation .
“ The efficacy of security systems has less to do with how clever they are , and more to do with how closely people work together by sharing and using the information they gather .”
