Intelligent LED Display Security Authorization Playback System Currently, general LED playback software only cycles through images and other content, making it difficult to control specific promotional effects. This system can tailor playback content based on different factors such as customer flow and vehicle license plates, targeting specific audiences: 1. When vehicles enter or exit, targeted content is displayed on the LED screen. 2. Different content is played on the LED or LCD screens depending on varying levels of customer traffic. 3. Specific images are displayed for different customer groups, enabling targeted advertising. 4. Supports images and Word documents. 5. Supports networked playback across multiple screens. 6. Ensures secure playback on LED screens. Currently, anyone with computer access can display information on LEDs, but this system effectively addresses this issue by preventing unauthorized users from controlling the LED display.
