Drones equipped with an optical zoom camera are mainly used in uniformed services to read vehicle license plate numbers or monitor mass events. They are also used in the inspection of infrastructure difficult to access. A great example is the inspection of wind turbines or the blades, where unmanned aircraft replaced high altitude works reducing maintenance costs.
Two solutions are most popular on the market: Yuneec H520 with E30Z camera and DJI Matrice 300 with Z30 camera. The cameras are similar in terms of technical parameters as well as the possibilities offered.
