Chapter 4 FAQ

Question
The network camera does not record sound.

Answers

• Check if the microphone is power-on, and the cable connection is normal.
• Check if the volume button of the microphone is turned to the lowest level. Adjust the volume button and try again.
• Connect a mobile phone to the camera and play sound to check if the recording function of the camera is normal.
• Connect the microphone to another type of the camera to check if the microphone is normal.
• Check audio cable connection. For the camera with a 3.5 mm audio connector, it is recommended to connect the front two sound channels of the 3.5 mm connector with the positive pole of the microphone’s audio cable. For the camera with terminal blocks, connect the audio in terminal with the positive pole of microphone’s audio cable.

Question
The sound picked up by the device is of poor quality, with high noise or rustling sound.

Answers

• Check if the cables are connected correctly. Poor quality of the cable and the cable connector may cause poor sound quality, such as low sound and high noise.
  Solution: Connect the device shell to the ground by cable, and use the twisted pair cable with good shielding performance.

• Check if the power supply of the microphone is a linear regulated power supply. Using the power of the network camera may cause ground loop and current sound.
  Solution:

• It is recommended to use POE power supply.

• Use an external linear regulated power to check the effect. If the noise disappears, it is recommended to use an external linear power supply.

• Check if the installation is not suitable for the device.
  Solution: Keep the microphone far away from and back to the noise resource, and isolate it from the vibration source. The pick-up holes should be faced to the sound source, and keep them as close as possible.

• Check if the parameters of the network camera are wrong.
  Solution: Refer to the user manual of the network camera to set the web parameters. Set the Video Type of the camera as Video&Audio and enable the audio function of the camera. Test before using the audio function. If there is sound when testing, check if the recording function is normal.
