Enhanced Design and Fabrication of Alarming System Based on Laser, LDR, and Smart Surveillance Integration

Abstract In today's rapidly evolving security landscape, protecting physical spaces such as homes, offices, and commercial properties requires more intelligent and responsive solutions. Traditional laser and LDR-based alarm systems have proven effective in detecting intrusions by identifying interruptions in laser beams. However, such systems typically lack the ability to identify the source of the intrusion. To address this limitation, we propose an advanced design that enhances the conventional setup by incorporating real-time surveillance capabilities. This upgraded system includes a security camera that automatically captures an image of the intruder or object upon interruption of the laser beam and transmits it to a pre-configured mobile device. This approach not only alerts the surroundings via a buzzer but also provides immediate visual evidence, thus facilitating quicker and more informed responses to security threats.
