How to install AXIS T8351 Mk II Wired Condenser Microphone

• Step 1 – Plan the placement: Choose a location near the primary audio source to maximize intelligibility while minimizing echoes. Consider line-of-sight to talkers and avoid direct proximity to loud HVAC equipment or reverberant surfaces. A central position in a conference area or at a receptionist desk often yields balanced pickup and reduces audio dropouts in the surveillance stream.
• Step 2 – Connect the mic: Connect the AXIS T8351 Mk II to the camera or encoder’s microphone input using the standard 3.5 mm connection. Use shielded audio cables to reduce interference, and ensure the connection is secure so there are no intermittent drops in audio during operation.
• Step 3 – Mount and route: Secure the microphone with the included clip or mount, and route the cable neatly along walls or under furniture. Use cable management accessories if available to keep the installation tidy, minimize tampering, and protect against wear from daily activity and cleaning routines.
• Step 4 – Configure the device: Access the Axis device’s web interface or your VMS to select the T8351 Mk II as the active audio input. Adjust input gain to avoid clipping and set the sampling rate and bit depth to match your surveillance requirements. If your system supports it, enable features that optimize voice clarity and suppress background noise for consistent performance across time.
• Step 5 – Validate and calibrate: Perform a live test with typical environmental conditions. Speak at normal conversation levels and verify that audio aligns with video playback during investigation audits. Fine-tune gain, distance, and placement as needed to achieve optimal intelligibility while maintaining a natural ambient sound when appropriate.
