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 getting better and better, and the original hard disks have gradually become The effect of the recorder is similar, but in daily use, there may be some problems with the use of pickups and webcams.
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 internal audio switch of 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 is not effective 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. Firstly, the external wiring power supply is used 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.
Â
The sound of the network pickup 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.
Large Diameter Drilling Machine
Large torque and large diameter full rotary drill is a kind of drilling equipment used in underground engineering construction. It has the following characteristics:
1. High torque: The rig is equipped with a powerful power system to provide a large torque output. This allows the rig to operate in a variety of geological conditions, including hard rock and soft soil.
2. Large diameter: The drilling rig has a large drilling diameter capability and can carry out large diameter drilling operations. This is particularly important in underground engineering, such as the construction of subway tunnels, underground pipelines, etc., need to drill large diameter holes.
3. Full rotation: The rig has full rotation function, which can rotate 360 degrees in a small working space. This allows the rig to flexibly adapt to different construction environments and improve construction efficiency.
