Huidu B8L Professional LED Poster Screen Control System Special Control Card for LED Advertising Screen

Short Description:

HD-B8L is a new control system for LED poster screens, which integrates player, third-party APP letter sending and local production program, and can replace computer to produce and play programs directly on the terminal equipment. HD-B8L has powerful interactive and broadcasting control ability, and supports Windows, iOS, Android and other platform terminals to wirelessly cast the screen. It supports the access of peripherals such as center control, camera, speaker, sensor, infrared touch, etc. With rich hardware interface and flexible broadcast control function, it is widely used in different application scenarios such as mobile poster screens, mirror screens, and splicing screens.
