Türk Telekom Group is a Turkish telecoms firm that offers its customers fixed line, mobile, data, and internet services. Türk Telekom enlisted the services of security installer Kent Güvenlik Sistemleri A.Ş. to provide security for the 240 Türk Telekom rural wireless cellular sites throughout the country. These 240 sites were not only in urban areas such as the nation’s capital of Ankara or Istanbul. Instead, many locations were scattered within scarcely populated and difficult-to-reach spots including high in the mountains. As many of these sites are unmanned, security for this infrastructure was a concern.
These centres, called “rural control rooms” serve to connect the cities to the mountains and vice versa through cellular means. Given the risk of earthquakes, cellular communication has taken on a higher national priority. In fact, most communication from rural mountain areas to cities is now cellular. Since this project were based on cellular technology, “the decision was made to use a hybrid solution for this particular large-scale project,” said Erdoğan Tekin, Technical Manager at Kent Güvenlik Sistemleri A.Ş.
After analysis of the demands of the project, Mr. Tekin chose a combination of the following Hikvision products.
DS-9016HFI-S Embedded Hybrid DVR
That Türk Telekom is a very large, long-standing company meant there are both analogue and IP cameras. Güvenlik Sistemleri A.Ş. knew the DS-9016HFI-S worked with both types.
DS-2CC1182P-A 600 TV lines box camera
Mr Tekin said: “The DS-2CC1182P-A’s durability was very, very important for this project. Due to the fact that many of these sites were in the mountains, this presented a dual problem. The first was the weather environment – it has massive shifts in extreme climate, including heat, wind, and bitter cold. The second was the inaccessibility of these sites. If a camera broke down, there really is not a realistic way to get a repair technician up there. Due to both concerns, the DS-2CC1182P-A’s IP66 rating and Hikvision’s reputation for quality and durability were extremely important.”
TV0309D-IR lens
Before Kent Güvenlik Sistemleri A.Ş. chose this model, the company tested other brands. After this testing, they found that no other brand offered the same results: namely the night time LED performance; the TV0309D-IR resulted in much sharper IR images.
As with the DS-2CC1182P-A 600 TVL camera, since both are in rural mountain-top areas, quality of DVRs is vital to ensure that the necessary images are sent to security in Ankara, and their Ankara-based PCs to monitor these stations. The same requirement holds true with the DS-9016HFI-S’s large 8 HDD memory. “In wintertime, it is virtually impossible to arrive at these sites, regardless of circumstance,” added Mr Tekin.
The final piece of this solution is iVMS-4200 Client Software. This allows the connection of all Hikvision hardware. In this Turkish case, all 240 sites – and their Hikvision hardware – are connected through managers’ PCs. Mr Tekin added: “Every major city in Turkey is using this client software. In this fashion, Ankara is connected to each of these cities and to each of these 240 rural sites through this convenient software program.”
