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.”
“We are proud to have been entrusted to work in partnership with Telmo to provide the city centre video surveillance system solution for the City of Turnov and to have the opportunity to demonstrate the flexibility and depth of the Wisenet range.”
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, the Wisenet XNP-6550RH was introduced at the beginning of 2019 in order to set a new standard for PTZ cameras designed for large open area applications. Its ability to capture clear, sharp images in daytime conditions, enables faces to be recognised up to 170 metres from the camera.
The technically advanced optical Defog feature built into the Wisenet XNP-6550RH is unique to Hanwha Techwin and involves the use of an optical low pass filter which is able to accept a higher light range in front of the camera’s image sensor, in order to reduce the influence of fog.
Sound Classification: 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.
In addition, Wisenet QNO-6070R 2 megapixel IR bullet cameras have been installed within and around the recently built city hall, which houses the police control room.
Control Room Video Wall
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). With 64 channels, the PRN-4011 will be able to handle a larger number of cameras should there be a need in the future to expand the system, whilst 8 Terabytes of built storage and RAID 5 support ensure all images can be stored for the required length of time.
Wisenet 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 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.
Using virtual enter/exit detection lines and with a 95% recognition accuracy whatever the environmental conditions, and even when vehicles are moving at speeds of up to 150 km/h, the Wisenet XNO-6120R ANPR camera solution is producing real-time reports on the number of vehicles entering the village, as well as generating alerts if vehicles on a black list are recognised.
Images and data captured by the Wisenet XNO-6120R ANPR and Wisenet QNO-6070R cameras are being recorded within the control room on a 32 channel Wisenet XRN-2011 NVR which is supported by SSM 2.10 video management software.
“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 which utilised analogue cameras and DVRs. In 2012, we were commissioned by the city to replace the DVRs with Wisenet NVRs and we were then able to initiate a programme of installing Wisenet IP network based cameras. 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.
