Securing the longest carnival in the world

Issue 2/3 2023 Surveillance

Located in the city of Gualeguaychú in Argentina, Carnaval del País is a festive season that runs for two 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 metres, which can hold up to 38 000 spectators.

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 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.

Surveillance solution

The team deployed several types of Dahua cameras around Corsódromo to monitor the situation during the carnival. A dozen 4 MP IR Vari-focal Bullet WizMind network cameras were deployed to cover various areas of the venue. Aside from providing clear 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 IP67 waterproof rating and IK10 vandal proof rating, making it durable and reliable for outdoor applications. Other cameras installed include 4 MP 32x Starlight IR WizSense network PTZ cameras, 2 MP 33x Starlight+ Laser WizMind network PTZ cameras, and Integrated Solar Monitoring System.

After each show, the situation at the entrance is also analysed through the recorded footage in order to reduce waiting/queuing time in the future. It also helps in deploying security personnel in the right location to avoid unauthorised entry, theft, or any other misdemeanour. What’s more, cameras with integrated alarm systems were strategically installed in crucial zones and were supervised by dedicated personnel on regular basis. All cameras are checked one day before each event to make sure they perform optimally.

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, avoids congestion and assists in assigning security personnel at crucial points around the venue to prevent incidents, all of which contribute to the enhanced on-site experience of every spectator and the improved security measures of Corsódromo.
