One of the top priorities for residences, enterprises, and corporations is security. Strong security measures can prevent unauthorized intrusions. The IoT-based anti-theft system is the ideal choice for protecting both residential buildings and commercial buildings. This IOT-based security system is set up to keep an eye on every floor of the building for any kind of strange movement. When activated, a single movement could send an alert, alerting the property's owners about unauthorized visits.

The Piezo sensor is activated to track any activity in and around the property once you leave a home or building, which is how it works. One of the better IoT projects to practice on is this one. As a result, if a thief broke into the house, the sensor would send the information to the microcontroller, which would then turn it into a signal for the camera to take a photo of the intruder. The users' smartphones are then automatically sent this image.
