A case study of an end-to-end IP network based video system at the Sisli Municipality’s new administrative offices.
Images captured by 170 Samsung Techwin cameras installed within the offices and surrounding areas are monitored in a central control room where they can be viewed live on Samsung Techwin monitors, while being recorded onto network video recorders.
Sisli is one of the major 32 districts of Istanbul on the European side of the city. Covering about 30 square kilometres, it is at the exit of the Bosphorus Bridge that links Asia to Europe.
Moving to a new building gave the municipality the opportunity to introduce smart building technologies to provide an efficient and environmentally friendly workplace for staff. The municipality’s leaders wished to see a video system installed that could similarly be regarded as ‘smart’.
The contract to install the IP video was awarded to Istanbul-based CCTV firm Melis Elektronik, who completed the project within three weeks.
Melis Elektronik worked with Samsung Techwin’s distribution partner in Turkey, NFS Teknoloji, to design a system that could assist security staff to monitor any suspicious activity and decide on a response.
Mrs Handan Anar, Deputy General Manager for NFS Teknoloji, said: “Having carried out a survey of the district and understood what the Sisli Municipality wanted to achieve, we had no hesitation in recommending to Melis Elektronik that we should supply a single source solution from Samsung Techwin that, from a technology point of view, could easily meet the clients’ expectations. Equally important, although Sisli Municipality wanted to take advantage of the very latest IP technology and did not want to compromise on image quality, there was not an unlimited budget for the project. Samsung Techwin’s competitively priced cameras, monitors and recorders were therefore an obvious cost-effective choice.”
Some 77 of the cameras installed are Samsung Techwin SND-6083P 2MP dome cameras with varifocal lens and 68 are SNV-6084R 2MP vandal resistant dome cameras.
Mrs Anar said: “These cameras were chosen partly because of the superb quality images which they are capable of capturing, but also because they are future-proof in that they are equipped with Samsung Techwin’s open platform WiseNetIII DSP chipset. The processing power of this chipset offers Sisli Municipality the opportunity to take advantage of the fact that the cameras can run multiple Applications if it wishes at anytime in the future such as video analytics, facial recognition, people counting and ANPR which can be downloaded to the cameras in a similar way to adding Apps to a Smartphone.”
Some 17 of the other cameras installed are Samsung Techwin SNO-7080R 3 megapixel weatherproof network bullet cameras with built-in motorised varifocal lens and IR LEDs. The SNO-7080R is capable of capturing evidence grade Full HD 1080P resolution images at 30 images per second, both during daylight hours and in pitch-black darkness, making it suitable for a wide range of applications requiring effective 24-hour surveillance.
The images from all the cameras are recorded on four SRN-4000 network video recorders enabling authorised staff to retrieve recorded video evidence of any suspicious activity. The SRN-4000 is able to record and multi-stream the transmission of images at a bandwidth speed of 400Mbps. It also offers the potential to record and store, via 12 internal hard drives, video captured by 64 x 2 Megapixel cameras for up to 108 days. The internal hot-swappable hard drives support RAID5 and RAID6 recording, which provides protection against unrecoverable read errors as well as whole HDD failure.
