  The system explained in this paper provides a compact smart surveillance
system. Recent years have seen the Internet of Things (IoT) dominating in
various fields of applications. With devices getting smarter and insurgence of
5G technology, the connectivity of people with devices is increasing. Smarter
surveillance systems are more reliable and accessible. A gyroscope is a MEM
sensor which detects angular disturbances. The principle is to detect opening
or knockdown of the door physically or by a gas cutter. The system is connected
to the user via Wi-Fi using ESP8266. Being a system with a low form factor,
this system can be implemented on doors, shops, cars, etc. An alarm system is
included in the system to alert the neighbors as well as to send a notification
to the user via Blynk mobile application. The proposed system is a portable
smart home solution for theft detection. The code for this system is available
