كاميرا الزر مع الصوت

يسجّل الميكروفون MEMS المدمج صوتًا بلوري الوضوح حتى من مسافة 5 أمتار.

تقنية التقاط الصوت

The audio system uses a micro-electromechanical systems (MEMS) microphone measuring just 2.5mm x 2.5mm, embedded in the button housing alongside the camera lens. This microphone captures audio at 48kHz sample rate with a signal-to-noise ratio of 65dB, which is comparable to professional lavalier microphones used in film production.

Advanced noise cancellation algorithms running on the onboard processor filter out ambient noise such as air conditioning, paper shuffling, and distant conversations. The result is a clean audio recording that captures the primary speaker with studio-like clarity, even in environments with significant background noise.

الصوت + الذكاء الاصطناعي: معالجة فورية

When used in exam mode, the audio capture serves a specific purpose. If an instructor reads questions aloud or provides verbal instructions, the audio stream is processed through speech-to-text and fed into the AI solver alongside any visual captures. This dual-input approach means the system can solve questions that are spoken rather than printed, covering oral examinations and viva voce scenarios.

The audio is processed locally on the GSM neckband processor and never transmitted to external servers, ensuring complete privacy and eliminating any network latency. Answers are delivered through the magnetic earpiece with a typical delay of 2-4 seconds from question capture to answer delivery.

The speech-to-text engine supports multiple languages including English, Spanish, French, German, Italian, Portuguese, Mandarin, Japanese, Korean, and Arabic. This makes the system suitable for language examinations where questions and answers are delivered in the target language.

التطبيقات العملية للتقاط الصوت

The audio capture capability extends the system's usefulness beyond visual-only scenarios. In lecture halls, the system can record an entire lecture while simultaneously capturing any visual materials displayed on screens or whiteboards. This creates a comprehensive record that combines video and audio in a synchronised format, which is invaluable for revision purposes.

For professional use, the audio capture is useful in meetings, interviews, and negotiations where having a covert record of what was said can be valuable. The high signal-to-noise ratio ensures that even in boardroom settings with multiple speakers and background noise, the primary conversation is captured clearly.

The audio feature is included in every button camera kit at no additional cost. See the full bundle contents or visit the main product page for pricing. For concealment details, see the hidden button camera page. For setup instructions, visit how it works.
