How to Configure Audio Settings on Dahua Surveillance Cameras71

Dahua surveillance cameras offer a wide range of audio capabilities, allowing you to capture and record sound along with video footage. Configuring the audio settings correctly is essential to ensure optimal audio quality and performance. This article will guide you through the steps involved in configuring audio settings on Dahua surveillance cameras.

Accessing Audio Settings

To access the audio settings, first log into the camera's web interface. Enter your username and password, then navigate to the "Audio" tab in the menu bar. The audio settings page will display various options for configuring audio input, output, and processing.

Configure Audio Input

The first step is to configure the audio input settings. This includes selecting the type of microphone connected to the camera and adjusting the audio gain level. Dahua cameras support both internal and external microphones.
Microphone Selection: Select the type of microphone connected to the camera from the "Microphone" drop-down list. Options include "Internal" for the built-in microphone or "External" for an external microphone.
Audio Gain: Adjust the audio gain level to ensure optimal audio levels. The gain can be increased or decreased using the slider or by entering a specific value in decibels (dB).

Configure Audio Output

Next, configure the audio output settings. This includes selecting the audio output device and adjusting the audio volume level.
Audio Output: Select the audio output device from the "Audio Output" drop-down list. Options may include "Internal" for the built-in speaker or "External" for an external speaker.
Volume: Adjust the audio volume level using the slider or by entering a specific value. The volume can be increased or decreased to match the desired loudness.

Configure Audio Processing

Finally, configure the audio processing settings. These settings allow you to enhance the audio quality by applying audio effects and noise reduction.
Noise Reduction: Enable noise reduction to minimize background noise in the audio recordings. Select the desired noise reduction level from the drop-down list.
Volume Normalization: Enable volume normalization to automatically adjust the audio volume level. This helps maintain consistent audio levels across different recordings.
Audio Compression: Select the audio compression format from the drop-down list. Options include "G.711 Ulaw," "G.711 Alaw," and "G.726." Different compression formats offer varying levels of compression and audio quality.
Bitrate: Adjust the audio bitrate using the slider or by entering a specific value. Higher bitrates result in better audio quality but consume more storage space.

Save Settings and Test

Once you have configured the audio settings, click on the "Save" button to apply the changes. To test the audio settings, speak into the microphone and check if the audio is being captured and played back correctly. Adjust the settings as needed to achieve optimal audio performance.

Conclusion

Configuring audio settings on Dahua surveillance cameras is essential for capturing high-quality audio recordings. By following the steps outlined in this article, you can easily configure the audio input, output, and processing settings to meet your specific requirements.
