Hikvision's two-megapixel network cameras are being used at the Rotonda building in Ljubljana, a new-build commercial development in the Slovenian capital overlooking the Alps.
The 15,000 square meter tower block is divided into two sections with separate entrances and foyer areas that require extensive CCTV monitoring and access control. Individual business units on each of the five floors are occupied by international banks, software houses and law firms. Flexibility of configuration and quality of IT infrastructure have been principal concerns in construction, with the Hikvision digital surveillance solution being an integral part of this offering.
The building owners required IP-addressable cameras throughout the structure with tender requirements specifying image quality that would allow ongoing development such as the introduction of video analytics. While the extent of glass coverage in the Rotonda has energy consumption benefits, there are implications for CCTV operation from the use of floor-to-ceiling windows.
The Hikvision cameras are also used in underground and outdoor parking lots across a range of lighting conditions. The need to capture highlight and shadow detail in the same scene required flexible optics in lobby areas, stairwells, lifts and communal spaces including a restaurant, with the cameras' motion detection capability proving important outside office hours.
The 130-camera system from Hikvision was implemented by Slovenian integrator Sintal dd. Sintal realized that their customer needed the image quality provided by progressive scan technology cameras and appreciated that facility managers required advanced vari-focal functionality and high-resolution images if they were to secure the site.
The integrator on this project specified Hikvision two-megapixel network cameras in the knowledge that the units would provide the required detail and optimum total resolution in high-contrast and back-lit situations. Color rendering and optimal exposure across the range of lighting situations encountered were key considerations, with the client being anxious to avoid camera 'noise' in the form of pixel blooming and vertical smearing which were a possibility with other vendors given the ambient lighting conditions.
The DS-2CD852MF-E cameras used at the Rotonda building allow Texas Instruments DaVinci hardware compression as well as offering H.264 dual-stream video compression. Users benefit from HD720P (1600x1200) video preview while additional features include electronic pan-tilt-zoom (e-PTZ) and masking of privacy zones.
The Rotonda office block has enormous political significance in that it is part of a commercial, infrastructure and residential development that will connect adjacent parts of the city which have been divided during two world wars and the city's history as part of Yugoslavia.
Mr Bostjan Kurmansek of Sintal d.d. said: "Since the office block is brand-new our engineers benefited from the fact that the structured IT cabling already in place proved suitable for transmission of surveillance images. Mapping, scheduling and layout were all simplified by Hikvision's video management software."
He continued: "This is a best-of-breed solution which exploits the efficiency of Hikvision's compression algorithms. The network has extensive storage, each NVR being allocated ten terabytes. The system uses 9 and 24-point switching from Cisco, with the network having been designed in-house by Sintal engineers. In the event of a problem with the Ethernet connection these cameras support local storage via SD memory cards."
Sintal d.d. is a leading security integrator in Slovenia, employing 1,700 staff and turning over $70m in 2009. The company secures more than 15,000 properties, and in addition to Ljubljana has offices in Prestranek and Nova Gorica on the Slovenian border with Italy. Sectors of operation include CCTV, access control, retail shrinkage and fire prevention.
Mr Polo Cai, Vice President of Hikvision, said: "Hikvision is aware that camera 'noise' not only compromises image quality but is wasteful of RAID/recording capacity. Every aspect of this application was based on the client's unusual imaging needs. While Hikvision is adept at integrating legacy analogue units into hybrid solutions, this location - being a new-build project - is distinctive for using IP-addressable technology throughout."
