Recording requirements
Judicial and service recording scenarios require intelligible, separated voice records.
Interrogation, courtroom recording, controlled visitation and government service counters need reliable voice pickup, speaker distinction and stable audio-video synchronization.
- Record conversations clearly in judicial, service and controlled environments.
- Separate two speaking roles where required.
- Reduce background noise and non-target voices.
- Support camera module integration for audio-video recording devices.
Solution capabilities
Directional pickup and role separation for traceable recording.
HAOKAI directional microphone modules support focused pickup, voice enhancement, noise suppression, automatic gain control and role-separated channel output for conversation recording equipment.
Role-Separated Channels
Left/right channel separation helps distinguish speakers in two-party recording scenarios.
Camera Integration
Camera modules can be combined with microphone arrays for complete audio-video front ends.
Selection guidance
Design the audio front end around the recording workflow and room layout.
Conversation-recording devices need clear target pickup, suitable channel handling and dependable integration with the host recording system. Audio modules should be evaluated as part of the complete installed solution.
Speaker layout
Confirm interview positions, mounting distance and whether two targeted conversation zones need separate channels.
System integration
Define the audio interface, camera synchronization path, storage workflow and any monitoring or review requirement.
Validation conditions
Test intelligibility with representative background noise, room acoustics and overlapping speech before production deployment.

FAQ
Technical questions before integration.
Can the microphone capture two speakers on separate channels?
A two-channel directional configuration can support role-separated capture. The achieved separation depends on microphone placement, room acoustics and simultaneous speech.
Is the solution suitable for interview rooms?
Directional pickup and camera integration can be evaluated for interview and conversation-recording equipment. The final layout should be validated in the installed room.
Does a microphone module make a recording court-admissible?
No. Admissibility depends on the complete recording system, operating process and applicable requirements. HAOKAI provides the audio-video front end, not a legal compliance determination.
Can camera and microphone modules be integrated together?
Yes. The audio front end can be matched with camera modules for purpose-built recording terminals and other embedded audio-video devices.
