- Bruit ambiant : While designed for low ambient noise environments, avoid placing the microphone near sources of constant noise (e.g., air conditioning vents, loud machinery).
- Discrétion: The compact size allows for subtle concealment if required.
4.2 Connexion du microphone

- Locate the 3.5 mm microphone input jack or 4-pin audio connector on your network product (e.g., IP camera, audio encoder).
- Insert the microphone's connector firmly into the corresponding port.
- Ensure a secure connection. The microphone is powered directly by the network product, eliminating the need for additional power cables.
5. Utilisation du microphone
5.1 Audio Capture
The AXIS T8351 Mk II is a hemispherical, omni-directional microphone, meaning it captures sound from all directions. This characteristic makes it effective for monitoring general ambient sound within a room.
- Once connected, the microphone will begin capturing audio as configured by your network product's settings.
- Adjust audio input levels and sensitivity through the interface of your connected network device to achieve optimal sound quality and prevent distortion.
5.2 Integration with Surveillance Systems
The microphone is designed to complement video surveillance by providing synchronized audio. Refer to your network product's documentation for specific instructions on:
- Enabling audio recording.
- Configuring audio triggers or events.
- Live audio monitoring.
6. Entretien
6.1 Nettoyage
Pour maintenir des performances et une apparence optimales :
- Gently wipe the exterior of the microphone with a soft, dry cloth.
- N’utilisez pas de produits chimiques agressifs, de solvants ou de nettoyants abrasifs.
- Ensure no moisture enters the microphone's openings.
6.2 Considérations environnementales
The microphone is designed for indoor use. Protect it from:
- Direct sunlight or extreme heat.
- Poussière ou saleté excessive.
- Strong vibrations or impacts.
7. Dépannage
7.1 Aucune sortie audio
- Vérifiez la connexion : Ensure the 3.5 mm connector is fully inserted into the network product's audio input.
- Verify Network Product Settings: Confirm that audio input is enabled and configured correctly in your network product's software interface. Check volume levels.
- Pouvoir: Since the microphone is powered by the network product, ensure the network product itself is powered on and functioning correctly.
- Compatibilité: Confirm your network product supports a 3.5 mm microphone input or 4-pin audio connector.
7.2 Poor Audio Quality (Distortion, Low Volume, Noise)
- Emplacement du microphone : Reposition the microphone closer to the sound source or away from sources of ambient noise.
- Niveaux d'entrée : Adjust the audio input sensitivity and gain settings on your network product. Too high a gain can cause distortion; too low can result in faint audio.
- Bruit ambiant : Identify and mitigate external noise sources in the environment.
- Intégrité du câble : Vérifiez que le câble n'est pas endommagé ou plié.
