The main goal of the Border Security Based Face Detection System project is to lessen the illegal activities that occur at the border. Humans often engage in illegal activity that could compromise the level of security. A suggested remedy is a security system that can prevent illegal activity by detecting intruders in high-security or restricted areas. The hardware component and the software component make up this system. A camera makes up the hardware component, and face-detection and face-recognition algorithms make up the software component. When a person enters the zone, the camera takes a number of pictures, which are then sent to the software for analysis and comparison with an already-existing database of reliable individuals. If the user is not recognised, legal action against them may be taken, and if the user is recognised and permitted to cross the border, an alarm is set off.
