Drone monitoring services of various kinds are now available where service providers provide you with continuous monitoring of whatever you are hiring them for. Monitoring the events where a lot of people have gathered through micro-drones can cut the cost greatly and improve the service as well. Some may argue that the small planes and helicopters can be used to monitor the events, and cameras can serve the same purpose as well.
However, planes and helicopters make a lot of noise; they are not discreet and are a huge distraction. In addition, cameras can’t be placed everywhere and can’t provide you with the necessary shots at difficult angles. Since drones fly without making noise and can provide shots from angles that normal security cameras cannot provide makes drones a very viable option.
