It is equipped with a built-in professional audio processor and is also loaded with industry-leading audio preprocessing algorithms such as smooth noise, transient noise, reverberation suppression, current suppression, beamforming, and automatic gain. It can effectively improve the recognition accuracy of the back-end speech recognition, semantic recognition and keyword recognition engines;
It is equipped with 32 highly sensitive digital microphones, each with a signal-to-noise ratio as high as 70db. It offers 360-degree omnidirectional sound pickup without blind spots, with a normal pickup distance of up to 20 meters. It can capture a minimum volume of 30dB, providing clear and natural voice that perfectly reproduces the original human voice.
It is equipped with one independent port, which is dedicated to device management. It can obtain various status information such as the sound quality and whether there is any sound during the operation of the device in real time, facilitating customers to discover and handle it promptly and avoiding the risk of recording but not recording.
The integrated design enables the default concurrent output of two PCM encoded digital audio channels at 16kHz and 16-bit sampling, which can meet the requirements of one recognition engine for speech recognition and one independent original sound recording and archiving. It also features one 48kHz sampled analog audio output channel for synchronous audio and video recording by video equipment such as IPC/NVR.
It is suitable for ceiling installation. The appearance design is novel, elegant and generous, with strong concealment, which can meet the needs of different customers.
