Nano-screen wall-mounted mobile installation
1. Core audio and video hardware configuration
1200W HD camera nano-screen: Built-in high-pixel camera supports HD video recording and photography functions, and is compatible with various video platforms such as Nail, Tencent Conference, etc., which can clearly capture classroom pictures and meet the needs of online teaching, teleconferencing and other scenes.
0-meter pickup microphone nano screen: equipped with 8 arrays of microphones, the pickup distance can reach 10 meters, equipped with intelligent noise reduction technology, which can effectively eliminate noise and echo, accurately capture the voices of teachers and students, and ensure clear audio transmission.
Nano-screen audio output equipment: equipped with 10W*2 stereo, the sound is loud and clear. With the microphone and camera, a complete audio-video interactive system is formed to ensure that there is no dead angle in classroom sound transmission.
2, audio and video interactive features
Nano-screen real-time interactive transmission: the camera and microphone work together to collect audio and video information in class in real time, and support scenes such as teacher-student interaction and group discussion in online teaching, making distance teaching like face-to-face communication.
Nano-screen multi-platform compatibility: it is compatible with many mainstream video conferencing and online teaching platforms, and can quickly access various teaching systems without additional equipment, simplifying the operation process and improving teaching efficiency.
Nano-screen intelligent noise reduction processing: the collected audio is processed by intelligent algorithm, and the interference factors such as noise and echo in the environment are filtered to ensure the purity of voice signals and improve the quality of audio interaction.
3. Audio and video adaptation between wall hanging and mobile installation
Wall-mounted installation of nano-screen: during installation, ensure that the camera is at an appropriate height (the distance from the ground is recommended not to exceed 0.85 meters) to ensure that the shooting range covers the whole classroom; The microphone pickup angle is optimized to meet the needs of audio and video acquisition in the fixed space of the classroom.
Nano-screen mobile bracket installation: the position of the equipment can be flexibly adjusted according to the teaching scene, and the camera and microphone can keep the best acquisition state with the movement of the equipment to meet the audio-video interaction needs of different classroom layouts and teaching activities.
4. Integration of audio and video technology and teaching scene.
Nano-screen classroom recording and playback: 1200W camera can record high-definition classroom video, combined with the audio collected by microphone to form a complete classroom record, which is convenient for students to play back and review after class, and also convenient for teachers to resume teaching.
Nano-screen distance teaching support: in distance teaching, high-definition audio and video transmission can make students clearly see the teacher's blackboard writing and experimental operation, hear detailed explanations, improve the distance teaching effect, and narrow the gap with offline teaching.
Nano-screen group discussion collection: the 10-meter pickup range can cover every corner of the classroom. In the group discussion session, the speech content of each group can be clearly collected, which is convenient for teachers to grasp the discussion and give guidance in time.
5. Additional functions of audio-video interaction
Nano-screen video recording control: it supports one-button video recording function, and can record key teaching contents in coordination with teaching progress. Video files can be stored in the device or the cloud for subsequent call.
Nano-screen audio adjustment: equipped with volume adjustment button, the audio volume can be flexibly adjusted according to the classroom environment to ensure that the sound is moderate in size, which will not affect the teaching and make all students hear clearly.
Nano-screen cooperates with other devices: it cooperates with wireless screen transmission, electronic whiteboard and other functions to simultaneously transmit audio and video information when displaying teaching content, thus realizing multi-dimensional teaching interaction.
