Dahua launches drones

As one classical Chinese poem goes, “The swallows once in mansions of the great now fly to ordinary peoples’ homes”. UAVs (unmanned aviation vehicles), more commonly known as drones, are just like those swallows: once only found in military applications and films, but are now widely used in daily life.

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 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 10 km, 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.

Application scenarios

Dahua drones are easy to operate and use in situations such as the following scenarios.

Power tower inspections: Often located in mountainous areas, power towers are hard and risky to reach.

Benefitting from 30X optical zoom, Dahua drones can capture HD images at a long distance. The thermal cameras they carry can accurately locate abnormally hot spots in cables and insulation terminals, thus preventing accidents from occurring.

Forest fire detection and control: Via the thermal camera, Dahua drones can detect suspicious hot spots invisible to the naked eye. At a height of 1500 m, a drone covers an area of 5 km², doing the inspection work of dozens of people in just one flight.

When there is a fire, Dahua drones can fly to the site in high temperatures and strong winds, transmitting relevant data to ground teams, so that they can make the right move using this information.

Detection for police: Arriving swiftly and secretly at crime scenes, drones record real-time visual information about locations, traffic and personnel using its multifunctional camera, which is capable of 30X optical zoom (allowing the drone to work from a long distance 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.

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 camera can capture the whole picture as well as specific details with a 38 minute battery life.

Inspection of high speed traffic: In daily patrols, when suddenly encountering the illegal behaviour of a driver, drones can capture the HD image of it from afar and keep the record as evidence. Information about the car, the licence plate and the driver will be immediately identified after the video is simultaneously transmitted to the back-end. In another scenario, if there is a traffic jam on a highway and nobody knows what is happening, a drone can provide real time and first hand images/video for the related departments to decide.
