FIELD OF INVENTION

The present disclosure relates to surveillance systems and devices.

BACKGROUND The background information herein below relates to the present disclosure but is not necessarily prior art.

The popularity of surveillance devices has increased manifold due to increasing crime rates in cities and metros. Conventional surveillance systems or devices such as Closed Circuit Television (CCTV) cameras monitor our surroundings, like in and around our homes and offices, and capture video for display as well as the videography for future playback. A CCTV camera footage can be used as an evidence in a crime investigation. A drawback of having a CCTV based surveillance is that it is non-reactive kind of surveillance.

Another conventionally used surveillance system is drone-based surveillance system. Drone based surveillance systems can be employed for crucial military missions, investigation of crime scene, and the like. The drone based surveillance has certain restrictions in the sense that it may amount to aerial trespassing. Further, usage of drones in flying applications requires a legal license. Adding up to the complications, a high quality camera is required along with a physically stable drone, which may be a costly setup.

Therefore, there is a long felt need to provide a surveillance system or device that alleviates the aforementioned drawbacks of the conventional surveillance systems.
