Using their own engineering teams, CPI installed Hikvision DS-2CD2T42WD-I8 and DS-2DE5120W-AE cameras covering the internal and perimeter areas of each remote site. Equipped with 4MP resolution, 120dB Wide Dynamic Range, 3D DNR, EXIR high performance LEDs and 80 metres IR range, the DS-2CD2T42WD-I8 4MP EXIR Network Bullet Camera was the perfect choice to monitor the remote substations, utilising its advanced performance to provide crystal clear images day and night.
Additionally, the Hikvision DS-2DE5120W-AE 1.3MP 20X Network PTZ Cameras were used to provide 3D intelligent positioning and 20X Optical Zoom, to deliver instant visual confirmation on any on-site intruder detection – and all in crystal clear 1.3MP resolution. In conjunction with PIR devices covering the sites’ perimeters, Hikvision Smart Video Content Analytics (VCA) technology embedded into the specified cameras was set-up to perform intruder detection utilizing Line Detection, to confirm alarm activations and eliminate false alarms.
Recorded locally to Hikvision IDS-9632 NXI-1816S Embedded Plug & Play NVRs, specified due to their superior performance and system stability, the NVR’s simple installation reduce engineering installation and set-up time on site, whilst up to 6 Megapixel recording resolution and a capacity of up to 4 SATA interfaces ensured the high-quality of local recording needed. In addition, with its AI technology to filter out false alarm on-site, which makes security operators quickly response to the accident. Both live and recorded images are transmitted over a wireless LAN, back to CPI’s own control room located at their National Operations Centre in Johannesburg.
Rapid response
At the control room, Hikvision’s advanced iVMS 5200 professional software with optional Video Wall driver was deployed to enable CPI operators to monitor the thousands of remote sites on 24/7 basis, via a ‘monitoring by exception’ basis. Monitoring the massive Hikvision integrated security system, in the event of an automated intruder alert being activated to indicate unauthorised movement on-site, security operators are able to quickly visually verify the activity in seconds, examining the high-performance camera network’s high-resolution images. During the process, all evidential video is tagged and automatically archived for future identification and prosecution usage. In the event of unauthorised intruders being detected, the CPI control room operators can instigate a host of anti-intrusion measures, including the despatch of rapid response teams to a specific location.
“These teams comprise highly trained operatives ready to tackle any situation,” continues Roy. “The Hikvision security system ensures we can respond very rapidly to any intrusion detected at the sites, and our manned guard response teams are equipped to get to sites as quickly as is possible, to catch the perpetrators in the act. We can even call on our Robinson helicopter R44 Police equipped with infra-red camera that can rapidly deploy personnel to reach the most remote locations in just a matter of minutes”.
“We work closely with the police and various local authorities, using the evidential video footage produced by the Hikvision systems to very good effect in prosecution cases. The high-definition quality of the Hikvision camera images have proved critical in detecting and prosecuting offenders of metal theft. Not only is it reducing these incidents, but it enables us to visually confirm the precise cause of an alarm at any remote site at the touch of a button. This means we no longer need to deploy response personnel to a site when it may be the subject of a false alarm – negating the waste of valuable man hours and costs, and vastly improving the effectiveness of our security operation.”
Effective protection
“We have been so impressed with the Hikvision security technology and the support we have received that we are continuing to roll out this Hikvision based security blueprint to many other power substation sites across South Africa,” Roy continues. “To date, over 1,000 electrical substations are protected by Hikvision systems - making a real difference to the provision of a reliable power service to all sections of industry and society across South Africa”.
“In future, we plan to harness more Hikvision technology to fortify power transmission security in South Africa. We’re looking forward to completing more successful projects with the assistance of Hikvision’s highly capable technology solutions.”
