The Brazilan government started to launch a national safe city project several years ago, and Dahua was one of the brands that has been used in the security deployment in over 100 cities, from the southern parts of the country all the way up to the north, from the state of Santa Catarina to Roraima, including cities such as Florianópolis, São Paulo and Rio de Janeiro; according to the company, over tens of thousands of Dahua devices have been included in the whole project, and the Florianópolis safe city project was one of the systems of note.

Florianópolis, the capital city of Santa Catarina, is known for its beautiful beach scenery and high quality of life; its pillar economies are information technology, tourism and services. Although it is revealed as one of the highest economic well-being cities in Brazil, less-developed regions do exist as well, just like any city elsewhere in the world. Naturally, the products and their deployment, required for the different areas are diverse and need to be applied according to-the-actual-conditions under the goal of what was termed as the two "M”s —  minimize crimes and maximize citizen safety.

For the rich zone, cameras are mainly installed at the crossroads, public entrances, school gates and elsewhere with high traffic flow, although it was essential to pay more attention to privacy in that area, and privacy masking functions provided in the Dahua DVR is ideal for the application, which allows the user to set a maximum of four masking areas for each channel. As for the less well-ordered areas, more focus is put on the key observation sectors, according to the data provided by police; thus, domes and fixed cameras are used in combination to better fix and follow the target.

Moreover, the data are processed in the Dahua DVR, and the volume is transmitted to its higher platform for overall management. The whole system runs Dahua comprehensive central management software and some customised functions are integrated into the CMS to make it more responsive in terms of time.

Meanwhile, a series of customisation features are offered in this case. Dahua redesigned the user interface and added USB and wireless WIFI modules; in addition, a network wizard to assess errors was built into the device to help technicians to diagnose the problem in a more effective way. As for cameras, image parameters and switching times (day/night) were customised as well. Moreover, Dahua prepared many special materials in this case, such as special printing, colour packaging, labels, specifications and CD, all the work was carefully double-checked and received with feedback.

"It is noteworthy that we successfully accomplished a large project like this,” said Thomas Ma, Sales Manager of Latin-America and Africa at Dahua Technology. "Actually, we see this project as an immersive safe city experience accumulator, during which, we spent a lot of time in communication and gave quite a strong support to make sure everything went well.”

"We reinforced our strength in an all-around way, and learned to have more alternatives and approaches to deal with a problem and then take care of it, finally we worked out a real life solution in a both time and money saving way, and that is why experience matters,” Ma added.
