Here is the Infrared Advantages:
1.Infrared light transmit signal,High Security,Interference Resistence and Against String Frequency
Infrared (IR) is short-range wave, cannot penetrate walls,which solve the string problems between the classrooms. It can realize that many sets of equipments used in many rooms simultaneously, so it is safe and has good isolation.
2.Emitter can be equiped with any receiver,Operate Conveniently
We can use the same frequency in the different rooms beacause of no string frequency. teachers can use the same microphone in different rooms ,so it is conveniet to manage.
3.Using light refraction to achieve 360 ° sensing in 30 m, it there are barrier and turn of the teachers ,the transmitting distance can be 10m.
4.Away from the electromagnetic radiation and interference, create a healthy, environmental -protected, health, green campus.
