There may be some problems with the use of pickups and network cameras. This paper proposes some methods for the problems to achieve the cooperation between the pickup and the network camera.
With the increasing use of network cameras, the cooperation between pickups and network cameras is increasing. Although the audio interfaces and solutions of mainstream network camera manufacturers are becoming more mature, the effects are gradually getting better, and the original hard disks have gradually become The effect of the video recorder is similar, but in daily use, there may be some problems in the use of the pickup and the network camera. In this paper, some methods are proposed for the problem to realize the cooperation between the pickup and the network camera.
No sound is recorded on the webcam
1. The pickup is not wired correctly. Sometimes the 3.5mm audio interface has mono and stereo differences. It is recommended to connect the two channels of the 3.5mm audio head and the audio cable of the pickup.
2. The power supply of the pickup is not correct. The pickup needs power supply to work. Generally, it is powered by +12V. It is necessary to confirm whether the pickup is powered. If the power is turned on, the general pickup has indicators to indicate whether the power indicator is displayed. And directly listen to the pickup at the pickup end for audio output, and then confirm the recording problem of the network camera after the audio output.
3. The internal settings of the network camera are incorrect. The network camera can set the data stream format to (video stream and mixed stream), and use mixed stream when using audio. In addition, you need to set the audio switch inside the network camera to be on, you can listen to it first, and when there is a sound, try to confirm whether the recording is normal.
The network camera does not work well after recording, there is noisy or current sound.
1. The problem of power supply of the pickup, the pickup generally needs to be powered by the linear regulated power supply. Sometimes, the power supply of the network camera is easy to cause the ground loop, resulting in current sound. First, use the external wiring power supply to confirm the effect. If it is good, then Try to use an external wiring power supply. If not, look for other reasons.
2. The matching problem between the pickup and the network camera, the network camera can generally be set to micin or linein. Generally, the network camera needs to be set to linein instead of micin, and then confirm the effect after confirming the linein.
3. The network camera recording parameter setting is incorrect. Some network cameras can set parameters when recording, so first listen to the effect of the network pickup, wait for the effect to be confirmed and then record.
The sound of the network pickup recording is intermittent.
1. The network connection is not good, test the network speed problem, if the network speed is good, then check if the network cable is normal.
2. Confirm the use of dedicated software.
