Dahua drone X820 guarantees public safety
As one classical Chinese poem goes, “The swallows once in mansions of the great now fly to ordinary peoples’ homes.” Unmanned aviation vehicles (UAV), more commonly known as drones, are just like those swallows: once only found in military applications and war films, now widely used in daily life. Military UAVs are now vastly outnumbered by civilian UAVs, whose use has been expanding to the commercial, scientific and even recreational realms. What distinguishes a Dahua drone from other civilian UAVs is the mission it is born with: to guarantee safety from above.

What is an industry-level drone?

There are in fact two levels of drones, consumer-level and industry-level. Dahua drones belong to the latter.

Consumer-level drones are mainly designed for use in aerial photography and personal shooting/sharing for entertainment. Naturally they are pretty straightforward to operate and can take images/videos that are easily editable, 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 inspections, forest fire detection, public event management, security supervision of long bridges, detection aids for police forces, and inspection of high speed traffic and other illegal incidents. It means that a very different set of functions is required for industry-level drones, including maintaining a high level of stability and safety, intelligent control, adaptability to different applications and environments, long distance mapping abilities, carrying capacity, and long battery life.

Current industry-level drones boast the capacity to transmit images of up to 10 km, and with access to multi-VMS platforms, they can stream real-time audio and video data to the screens of a control center, 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.

Application scenarios

Dahua drones are easy to operate and use in situations such as in each of the following scenarios:

Forest fire detection and control

Via the thermal camera it carries, a Dahua drone can detect suspicious hot spots invisible to naked eyes. At a height of 1500 m, the drone covers an area of 5 km², doing the inspection work of dozens of people with just one flight.

When there is a fire, Dahua drones can fly to the site despite high temperatures and strong winds, transmitting relevant data to ground teams so that they can make the right moves using this information. Once the fire has been extinguished, the drone’s overhead inspection can prevent a second fire. In this sense, the Dahua drone is one of the best aids to help firefighters.

Detection for police

Arriving swiftly and secretly at crime scenes, Dahua drones record real-time visual information about locations, traffic and personnel using its multifunctional camera, which is capable of 30x optical zooming (allowing the drone to work from a long distance away where it won’t be noticed by criminals); thermal imaging (allowing the drone to work at night); and automatic recognition of faces or wanted cars.

Using wireless transmission the information collected is accessible to all mainstream VMS platforms. In short, it is a very powerful assistant for the police.

Public security management

At public events like concerts, sports meetings and marathons, a Dahua drone can provide special security surveillance from up high because of its multiple flying modes (circling around and tracking down the target), while its powerful camera can capture the whole picture as well as specific details, while benefiting from its long 38 minute battery life.

The beauty of a Dahua drone lies not only in its ability to work from afar but also its safety while flying. Having undergone all sorts of extreme tests, this means when in use, a Dahua drone will not disturb the crowd below at all.

Take the New York City Marathon for example. There were thousands of participants and spectators spread over a range of over 26 miles. It was quite a challenge to set up an effective surveillance system for such a one-day event. Dahua drones can be very useful for such scenario. If properly deployed, eight 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 and staying still for a few minutes at each of the 6 patrol points, which are 1 km apart, to have a good look at the situation on the ground. These drones will be flying at 100 m above ground to produce sufficient clarity to effectively identify mass casualty incidents such as stampedes or traffic accidents.

Obviously similar deployment of drones can also be applied to scenarios such as music festivals, open-air concerts and important political rallies. This will not only help security companies to work more efficiently but also provide evidence if illegal incidents occur.

In conclusion, Dahua drones can play a key role in various public security scenarios. Dahua has leveraged the latest technology trend and adapted it to enable a “Safer Society and Smarter Living.” This is the future that Dahua drones are helping us move towards.
