As the intruder walks near a sensor pole, a PIR motion sensor detects movement. A digital red alert icon flashes above the pole. Quickly transition to a 3D digital schematic showing the PIR sensor wired to an Arduino Nano and a 433 MHz RF transmitter. Bright signal arrows indicate RF transmission. The signal travels through a visual data path to a defense command center. Inside, a Python-based GUI flashes: “Intrusion in Zone 4.” The zone map blinks red. A synthetic female voice says, “Alert! Intrusion detected in Zone 4.” The GUI displays live footage from an ESP32-CAM stream showing the intruder. Interface glows with urgency. Clean, realistic, and high-tech.
