Product details
An automatic recording and broadcasting system that integrates automatic mode, manual mode, and interactive teaching. It supports single stream multi screen recording, movie mode courseware recording, automatic publishing, real-time live streaming, and remote interaction. It is suitable for high-quality public courses, interactive teaching, micro classrooms, remote teaching and research, teaching evaluation, and other occasions.
Integrating the first domestic recording, positioning, and tracking guidance into one, it is easier to deploy, energy-saving, environmentally friendly, and easy to maintain and use compared to the split type.
Customized trigger based tracking and guidance strategy for the podium
You can customize the switching plan according to different specifications of the podium and the teaching habits of the teacher. It is possible to customize tracking strategies based on the actual environment in the classroom, including irregular classrooms, tiered classrooms, and opposite sex classrooms, which can easily achieve fully automatic tracking and recording.
Image recognition tracking system
It can automatically recognize the target location and control the camera to track and shoot songs. The entire system does not require manual intervention, and classrooms and students do not need to wear any equipment, truly achieving normalized teaching, greatly improving recording efficiency, and ensuring teaching quality. Support multi-level close-up mode, strong adaptability, not affected by strong light, sound, electromagnetic and other environmental factors.
