Over 1,800 video surveillance cameras supplied by Hanwha Techwin have been installed to help protect local authority and government buildings located throughout the Kocaeli Metropolitan Municipality in Turkey. With a history which can be traced back to 1320, Kocaeli’s fast expanding economy has seen it grow to becoming one of the 10 largest municipalities in Turkey, with a population of 1.8 million people.
Hanwha Techwin has worked closely over the last twelve months with 10 separate system integrators who were awarded the installation contracts for various phases of a project which has seen a large number of different models specified from the Hanwha Techwin range of Wisenet cameras. Each of the 1,800 cameras were carefully selected to ensure they were able to operate effectively and capture high quality images in their respective installed locations, regardless of the environmental or lighting conditions.
Among the cameras which have been installed there are approximately 300 Wisenet Lite SNO-L6083R 2 megapixel weatherproof network IR bullet cameras. As is the case with the 134 SND-L6083R 2 megapixel network IR dome cameras which have also been installed, the SNO-L6083Rs are equipped with motion detection, privacy masking zones, audio support, PoE and an SD/SDHC memory slot. They also feature LDC (Lens Distortion Correction), which compensates for the image distortion that can occur with wide angle lenses.
A hallway view function for the monitoring of narrow vertical areas such as corridors, is likely to be of considerable benefit within local authority and government buildings. It enables the camera to capture images with a 9:16 x 3:4 aspect ratio that works effectively in tall and narrow spaces, with the added bonus of minimising bandwidth and video storage requirements
140 of the installed cameras have been selected from the Wisenet Q series. These are packed with innovative features such as H.265 compression and WiseStream, a complementary compression technology which dynamically controls encoding, balancing quality and compression according to movement in the image. When WiseStream is combined with H.265 compression, bandwidth efficiency can be improved by up to 75% compared to current H.264 technology, enabling Kocaeli Metropolitan Municipality to benefit from one of the most bandwidth friendly camera series available.
Depending on the number of cameras installed at each building, Hanwha Techwin has also supplied either 4, 8 or 16 channel recording solutions. A total of 74 NVRs have been deployed to ensure evidence of any suspicious activity is recorded for either instant playback or stored for evidence purposes.
