IR is invisible light and IR systems typically require a direct line-of-sight from the transmitter (microphone) to the receiver (IR Sensors) to operate. The item was designed with ultra-high output IR circuitry that allows the IR pulses output from the microphones to reflect off ceiling, wall and hard floor surfaces. The IR Sensors are designed to 'see' IR from any direction, allowing uninterrupted presentations.

Work under 2.4G uniform frequency for emitters universal using, can be operated by different person at same place without interference.

The whole system is portable, the emitter can be hung around the presenter's neck on a switching lanyard, equipped with rechargeable lithium battery or be charged by Mini-USB port, save power and no radiancy.
