Overview: Due to the pandemic and Delta cases in Israel, the first hospital in Israel for treating coronavirus patients was established. The hospital needed to offer more beds and create more special wards for the infected patients. The head of the hospital requested for an advanced system that could monitor patients on-site or remotely to protect the doctors and nurses from cross-infection in the hospital. Non-contact communication Challenges: Lack of devices for contactless communication: The hospital did not have enough equipment to realise non-contact communication between staff and patients, which could have increased the risk of cross infection. Insufficient remote surveillance: The hospital needed to build larger wards for infected patients, which a 24/7 monitoring system must cover. Installing the right cameras for such a large space could be very challenging. Video intercom solution Highlights: Video intercom solution: The patient’s bed is equipped with Dahua's VTO. Once an emergency occurs, the patient can directly call the VTS management device at the nurse’s station through the VTO. At the same time, through the real-time preview function of VTO, the staff in the nurse station can remotely monitor the patient's condition and communicate with the patient in real-time to provide necessary care. Monitoring & management system: Through Dahua's DSS management platform, the entire CCTV monitoring system and video intercom system in the hospital can be unified and managed. For the hospital managers, it not only improves the efficiency of monitoring and management, but also provides additional security for hospital workers to a great extent! Professional CCTV devices Significance: Dahua provided the hospital with video intercom products and Dahua professional CCTV devices that greatly helped them prevent direct contact with patients to reduce cross-infection inside their premises. With the help of Dahua’s solution, the hospital was able to centralise all their surveillance systems for easy management.
Located in the city of Gualeguaychú in Argentina, Carnaval del País is a festive season that runs for two whole months, holding the world record as the longest carnival in the world. It is full of lively events featuring energetic samba dancers dressed in sequins and feathers as well as parades of colourful and beautifully crafted floats. To accommodate the event, the city built its own Sambadrome called the Corsódromo, the first of its kind in Argentina. It has an extension of 500 metres long and a track width of 10 useful metres, which can hold up to 38,000 spectators. Challenges at Carnaval del País Implementing an outdoor video monitoring solution that can cover a capacity of 38,000 people was a massive challenge and not an easy task for the entire team. The client required a surveillance system that can monitor the crowd’s security; from the moment they enter the stadium, watch and enjoy the show, until they leave the premises. Recorded video footage must also be readily available for further analysis in case of an incident. Solution: Vari-focal Bullet WizMind Network Cameras This intelligent camera is also equipped with deep-learning algorithms that enable intelligent functions The team deployed several types of Dahua cameras around Corsódromo to monitor the situation during the carnaval. A dozen 4MP IR Vari-focal Bullet WizMind Network Cameras (IPC-HFW5442H-ZHE) were deployed to cover various areas of the venue. Aside from providing clear and vivid images, this intelligent camera is also equipped with deep learning algorithms that enable intelligent functions such as video metadata, smart object detection, people counting, and more. It has an IP67 waterproof rating and an IK10 vandal-proof rating, making it durable and reliable for outdoor applications. Cameras installed Other cameras installed include 4MP 32x Starlight IR WizSense Network PTZ Cameras (SD5A432XB-HNR), 2MP 33x Starlight+Laser WizMind Network PTZ Camera (DH-SD6AL233XA-HNR), and Integrated Solar Monitoring System (DH-SD6C3432XB-HNR-AGQ-PV). After each show, the situation at the entrance is also analysed through the recorded footage (via NVR5216-8P-I/L) to reduce waiting/queuing time in the future. Integrated alarm systems All cameras are checked one day before each event to ensure their optimal condition and performance It also helps in deploying security personnel in the right location to avoid unauthorised entry, theft, or any misdemeanour. What’s more, cameras with integrated alarm systems were strategically installed in crucial zones and were supervised by dedicated personnel regularly. All cameras are checked one day before each event to ensure their optimal condition and performance during the event. Results: Efficient monitoring solution The Dahua video monitoring solution deployed in Corsódromo for the Carnaval del País is a technological step forward from what it had in previous years. Through this new monitoring system, the management of the venue can efficiently monitor the situation inside the stadium and make necessary adjustments if needed. It helps optimise the entry time of spectators to avoid congestion and assists in assigning security personnel at crucial points around the venue to prevent incidents from happening; all of which contribute to the enhanced on-site experience of every spectator and improved security measures of Corsódromo.
The city of Jesús María in Argentina has invested in a 114-camera monitoring system from Dahua, to help provide safety to residents and to support security and emergency assistance departments (e.g. firefighting, ambulance) in case of emergency. Challenges Jesús María is a vibrant busy city located in Cordoba Province. As such, the city needed an intelligent monitoring system to improve traffic flows and help the emergency services through heavy traffic. Monitoring centre It must be able to ensure safe transit without obstacles and immediate arrival of the response team when needed, covering surrounding areas comprised of hospitals, schools, banks, municipal offices, etc. “The main challenge was to find the right solution and products so that the different municipal departments could benefit from the implementation of the monitoring centre,” said Marcos Romero of Dahua Technology in Argentina. AI solutions AI solutions were presented, including how to apply them correctly to the way the city operates" Marcos Romero adds, “There were some very long meetings at which all of the AI solutions were presented, including how to apply them correctly to the way the city operates, and how to correct or modify aspects so that the work of all organisations flowed successfully.” He continues, “This ranged from cameras with traffic analysis capabilities, to existing analogue PTZ and zoom cameras, all to ensure everything worked correctly with the operational software.” Solution The advanced AI cameras are installed around the city’s infrastructure and are monitored in a state-of-the-art control centre. Dahua equipment installed in Jesús María includes 8-port PoE switches, 4MP Lite IR varifocal bullet cameras, 2MP IR varifocal bullet cameras, 4MP ANPR cameras, Network/control/dome keyboard and joystick, 64-channel 8HDD WizMind NVRs, and 22-inch industrial-grade LCD monitors. The availability of Dahua’s DSS PRO video management software which provides intuitive and seamless control of the entire system was a key factor that led to the selection of the all-Dahua solution. Results Benefits It significantly improved local transportation safety, making sure that residents are secure The creation of ‘safe corridors’ within Jesús María has resulted in several benefits for the city and its residents. It significantly improved local transportation safety, making sure that residents are secure and emergency responders will be alerted and arrive in time without delay. Improved efficiency “Since the implementation of the monitoring centre, work between the security departments and relevant transportation departments has improved markedly,” added Mr. Romero. The implementation of Dahua’s intelligent solution is reported to have led to an increase in commercial activity and people in the city, as well as the improved efficiency of emergency services.
In 2020, the forest areas in Dali Prefecture, Yunnan Province were reported to have reached 1.855 million hectares, ranking among the top in the country. In addition to absorbing carbon dioxide, conserving water sources, and maintaining water and soil, these ancient forests also shelter a large number of rare wild animals and plants. These natural wonders are a risk if a forest fire breaks out, causing drastic damage and endangering the inhabitants of the forest. Wireless transmission systems Since 2020, Dahua has been assisting Dali Prefecture in building front-end systems and installing wireless transmission systems in key protected zones as well as areas prone to forest fires. More than 500 cases of illegal use of fire in the wild and 7 cases of forest fires have been detected since then. 24/7 real-time monitoring Dali Prefecture's forest coverage rate reached 65.51% in 2020. Twenty-eight nature reserves of various types and levels were established throughout the prefecture, with a total area of 181,000 hectares. The vast forest constitutes an ecological security barrier, but its massive area makes it difficult to monitor forest fires. "Burning straws, cooking fires, etc. are all common wildfires, but even seemingly insignificant areas can become the source of forest fires," a local forest ranger said. Visible light and thermal imaging technology The dual-spectrum thermal imaging cameras deployed in the forest enable the fire prevention video monitoring system Multiple round-the-clock patrol points were set up to monitor and observe the surrounding forest areas 24/7, with 3 people in each shift (changes every three days). The mountains are high and the slopes are steep, and sometimes thorns are everywhere, especially at night. Nevertheless, with the help of modern technology, these diligent forest rangers always persevere in accomplishing their tasks and duties. The dual-spectrum thermal imaging cameras deployed in the forest enable the fire prevention video monitoring system to complete an automatic cruising round in just 15 minutes. Based on visible light and thermal imaging technology, it can detect a fire source of about 2 square metres within a range of 5-10 kilometers. Accurate multi-dimensional positioning of fire source Flammable coniferous trees such as Yunnan pine and Huashan pine are widely spread in the forest areas of Dali Prefecture. Large-scale and high-intensity forest fires could start in these areas in a short period. In case of a sudden fire, quickly locating the source of the fire can add more significant time for firefighting. Smart fire detection system Technologies such as dual-spectrum video monitoring, intelligent image analysis and recognition, and three-dimensional positioning enable the smart system to detect a fire, quickly locate the fire source and automatically send an alarm to on-duty personnel. In forests with hundreds of hectares (or even thousands of hectares), the source of the fire can be accurately located within 50 metres, allowing the firefighting team to quickly reach the location and providing more time to control the fire. The efficient investigation, assessment, and handling of the fire situation Extinguishing forest fires requires the full cooperation of the frontline and the command centre. The command centre quickly communicates with the frontline about firefighting strategies based on the actual fire situation. But how can they understand the situation at the scene if they are far away? It enables operators to check and assess the situation in time, and quickly deal with the fire This particular job is handed over to the visual forest fire prevention video monitoring system. This smart security system synchronously displays real-time images in the monitoring centre, combined with other corresponding data such as space, time, fire type, etc. It enables operators to check and assess the situation in time, and quickly deal with the fire according to the corresponding plan. Full coverage of network transmission in forest areas Considering its vast areas, transmitting valuable information from the forest could be a daunting task. "The mountain area is large and widely spread. Sometimes, there’s even no mobile phone signal. To allow the command centre to see the scene in time, we also built a wireless transmission with front-end equipment." "The smart system covers all the video points in the forest and sends forest fire information back to the command centre in real-time," a Dahua technical engineer explained. Early detection, reporting, and handling The forest fire prevention video monitoring system that Dahua helped build in Dali Prefecture offers wide-coverage, all-weather, high-precision, and intelligent 24/7 monitoring that can automatically detect fire and locate its source in time. Early detection, reporting, and handling of the fire situation using digital intelligence can effectively safeguard the safety of these local ecological barriers. With abundant experience in developing smart fire prevention systems, Dahua will continue to innovate and create technological breakthroughs to protect the environment and natural resources.
