Czech city addresses anti-social behaviour with surveillance

Turnov, Czech Republic

When the City of Turnov decided to invest in a new city centre video surveillance system in order to deter anti-social behaviour and create a safe environment for its 14,000 inhabitants, it awarded the contract to supply the cameras to Hanwha Techwin.

Turnov, which is located in the north of the Czech Republic, has traditionally been known as a centre for gemstone polishing, glass craftsmanship and arts. It is at heart of the Bohemian Paradise nature reserve which attracts large numbers of tourists throughout the year,

Wisenet cameras manufactured by Hanwha Techwin have been installed by Telmo a.s., a Hanwha Techwin Diamond STEP partner based in Prague, at key locations throughout the city to enable police to closely monitor and respond quickly to any suspicious activity.

Hanwha Techwin’s pre-sales and technical teams worked closely with Telmo and city officials to ensure the best Wisenet cameras models were specified for each location. “Although city officials wanted a cost-effective solution, they also wanted to take advantage of the latest advances in technology and were not prepared to compromise on quality or functionality,” said Jaroslav Novovesky, Business Development Manager – Czech & Slovakia for Hanwha Techwin Europe. “The wide range of Wisenet cameras available meant that we were able to recommend 12 different models, with each offering the most cost-effective solution, whilst meeting the exact requirements for each camera location.”

Among the cameras installed is the Wisenet PNM-9030V 15 megapixel panoramic camera. Deployed to allow operators to view any activity within Turnov Square, the Wisenet PNM-9030 which is designed for large open areas, is equipped with multi-sensors which enable it to capture superb quality seamlessly stitched 180 degree images.

The exceptionally high resolution of the captured images allows control room operators to digitally zoom in to observe close up detail of any incidents. The Wisenet PNM-9030V is also equipped with tampering detection as well as a number of different types of Intelligent Video Analytics (IVA), such as audio, loitering, motion, direction, enter/exit detection and object appear/disappear detection.

A 2 megapixel Wisenet XNP-6550RH has been deployed at the city’s railway station. With a 55x optical zoom, a Gyro sensor for accurate stabilisation in windy conditions, optical ‘Defog’ and built-in IR LEDs to capture high definition images at night at a distance of up to 500 metres. Its ability to capture clear, sharp images in daytime conditions, enables faces to be recognised up to 170 metres from the camera.

Additionally, both the Wisenet PNM-9030V and Wisenet XNP-6550RH have an audio analysis function which recognises critical sounds, such as gunshots, explosions, screams and broken glass, and then immediately raises an alarm to ensure operators respond quickly to any emergencies.

Images from all the IP cameras are securely transmitted over the network to enable operators to monitor activity in real-time via their workstations or the control room’s video wall. Operators are also able to retrieve video evidence recorded and stored on a Wisenet PRN-4011 Network Video Recorder (NVR). 

Wisenet SSM 2.10 video management software has been integrated into the system to provide operators with a user-friendly and efficient method of managing and monitoring the cameras, as well as configuring which cameras are displayed on the video wall.

The nearby village of Malá Skála, which does not have its own police force, has also contracted to use the services of the City of Turnov’s control room. Operators within the control room are monitoring images captured by Wisenet QNO-6070R 2 megapixel IR bullet cameras installed throughout the village, as well the video and data captured by a Wisenet XNO-6120R bullet camera which incorporates ANPR technology developed by Hanwha Techwin’s technology partner, FF Group.

“We are very pleased that the City of Turnov has chosen to maintain a long term partnership with Telmo and Hanwha Techwin Europe,” said Ales Pachman, a senior technician at Telmo. “The partnership was first formed in 2006 when we designed and installed the city’s first video surveillance system. The final phase of the programme was completed at the beginning of 2019 along with a complete upgrade of the city’s central control room. There is no doubt that the excellent working relationship established over a long period of time between Telmo and Hanwha Techwin’s pre-sales and technical teams, has greatly contributed to our ability to meet this valued client’s requirements."
