Dahua Drone X820 contributes to public safety

Hangzhou, China

As one classical Chinese poem goes, “The swallows once in mansions of the great now fly to ordinary peoples’ homes”. UAV (Unmanned Aviation Vehicle), more commonly known as drones, are just like those swallows: once only found in military applications and war films, are now widely used in daily life. Military UAVs now are vastly outnumbered by civilian UAVs, whose use is expanding to commercial, scientific and even recreational realms. According to Dahua, what distinguishes a Dahua Drone from other Civilian UAVs is the mission it was born with: to guarantee safety from above.

There are considered to be two levels of drones, consumer-level and industry-level. Dahua Drones belong to the latter. Consumer-level drones are pretty straightforward to operate and can take easily editable images/videos, often with automatic beautification and other entertainment functions. This contrasts with industry-level drones that are built for serious public security missions such as power tower inspection, forest fire detection, public event management, security supervision over long bridges, detection aid for police forces, inspection of high speed traffic and other illegal incidents. It means that a very different set of functions are required for industry-level drones, including maintaining a high level of stability and safety, intelligent control, adaptability to different applications and environment, long distance mapping abilities, carrying capacity, and long battery life. 

The current industry-level drones boast the capacity to transmit images at up to 10km, and with access to multi-VMS platforms, they can put real-time audio and video streaming on the screen of a control centre, thus providing information for police or security companies to solve the problem on site, such as directing crowds for evacuation via the correct route or sending out a medical team to the location where it is needed.

Dahua Drones have been tested and designed for easy operation and for the ability to work remotely whilst still maintaining safety whilst flying.

Take the New York City Marathon for example. There are thousands of participants and spectators spread over a range of over 26 miles. It is quite a challenge to set up an effective surveillance system for such a 1 day event. The Dahua drone can be very useful for such scenario. If properly deployed, 8 sets of model 820 drones can deliver very good coverage for the entire marathon. Each drone could take care of a 6 km range by patrolling back and forth, staying still a few minutes at each of the 6 patrol points 1 km apart to have a good look at the situation below. These drones will fly at around 100m above ground to produce sufficient clarity to effectively identify mass casualty incidents such as stampedes or a traffic accident. Obviously similar deployment of drones can also be applied to scenarios such as music festivals, open-air concerts and important political rallies, which will not only help security companies to work more efficiently but also provide evidence if illegal incidents occur.

The inspection of bridges is another application example. The construction of massive bridges requires inspection, which usually takes many boats, equipment and experienced staff. The Dahua drones can greatly simplify the process and reduce the cost and save time. Dahua drones would fly all around the bridge, checking erosion, damage and other damages, while keeping a numbered record for experts to analyse afterwards. It’s worth adding that Dahua drones boast an outstanding ability to resist the wind (up to Windspeed 7.0), and are fully capable of maintaining highly accurate suspension over the river and providing stable visual information.

In conclusion, Dahua drones can play a key role in various public security scenarios. Dahua has taken the latest technology trend and adapted it to help enable a safer society and smarter living.
