With the increasing use of IP cameras, the cooperation between the audio monitoring device and IP cameras is increasing. Although the audio interfaces and solutions of mainstream IP camera manufacturers are becoming more mature, the effects are also gradually getting better, it has gradually been similar to the original DVR, but in daily use, there may be some problems with the use of audio monitoring and IP cameras. Sizheng audio monitoring devices have proposed some methods for the problems to achieve CCTV microphone and the perfect match for the IP camera.
1. There is no sound recorded on the IP camera.
The CCTV microphone 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 CCTV microphone together.
The power supply of the CCTV microphone is not correct. The audio monitoring device needs a power supply to work. It is usually powered by +12V. It is necessary to confirm whether the CCTV microphone is powered. If the power is turned on, the general CCTV microphone has indicators to indicate whether the power indicator is displayed. And directly listen to the CCTV microphone at the audio monitoring device end for audio output, and then confirm the recording problem of the network camera after the audio output.
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.
2. The IP camera does not work well after recording, there is noisy or current sound.
For the power supply problem of the CCTV microphone, the CCTV microphone 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 a 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.
For the matching problem between the audio monitoring device and the IP camera, the network camera can generally be set to mic in or line in. Generally, the network camera needs to be set to line in instead of mic in, and then confirm the effect after confirming the line in.
The network camera recording parameter setting is incorrect. Some IP cameras can set parameters when recording, so first listen to the effect of the audio monitoring device, wait for the effect to be confirmed and then record.
3. The sound of the CCTV microphone is intermittent.
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.
Confirm the use of dedicated software.
