How to connect the camera to the conduit of the sound card

How does the sound of the sound card reach the camera?

I wonder what grade your Sony camera is? Forget the small DV at home. There are usually cameras.

Line In the linear audio input interface, just connect a line from the computer sound card output to this interface. Pay attention to adjust the electrical frequency of recording before recording.

Connect the H6 headphone jack to the audio input of the SLR microphone.

It is realized by connecting recording cable to H6 headphone jack and SLR microphone audio input, and synchronous recording is realized by connecting ZOOMH6 audio output to SLR camera microphone audio input.

How to install the camera How to install the camera and the steps?

Surveillance cameras are mainly used for commercial purposes, such as shopping malls and shops. But I bought a surveillance camera and stopped installing it. I'm really anxious. The following is the installation and installation method of the surveillance camera.

Camera installation method and steps

If the analog surveillance camera is connected to the computer, the following operations are required:

1. Buy DC DC 12V power supply, camera bracket (except hemisphere), 75-3 video cable with appropriate length, two-core power cord, acquisition card and a pair of BNC heads;

2. Install the acquisition card on the computer motherboard and install the driver;

3. Put the camera in a proper position, connect the power cord, weld the BNC connector, and pull the cable to the computer;

4. Weld a BNC connector, connect it to the acquisition card, and turn on the power supply.

5. Just configure the acquisition card and change the storage time or mode.

If you monitor the camera digitally, you need to do the following:

1. Buy DC DC 12V power supply, camera bracket (except hemisphere), network cable with appropriate length and two-core power cord;

2. Put the camera in a suitable position and connect the power cord and network cable.

Pull the cable to the computer network card;

3. Install ip scanning software of digital camera;

4. Log in to the camera, just configure the camera and change the storage mode.

Description of high quality images

If you want to take high-quality images, users should pay attention to the display settings of PC screen, and the screen color should be at least 65. 000; In addition, although the flat LED display screen is very convenient to use,

But when looking at the image, the effect is not as good as CRT screen. Other requirements for high quality images are as follows:

Avoid backlighting

Generally speaking, the dynamic adjustment ability of the camera is limited, so try to avoid bright areas on the image, because bright images will lead to overexposure and objects will appear too dark.

Reduce contrast

The user can adjust the exposure of the camera,

So as to obtain more even illumination.

Precautions for installing camera

(1) Camera wire: The rated voltage of the wire is greater than the working voltage of the line, and the insulation of the wire must adapt to the installation mode of the line and the corresponding laying environmental conditions.

(2) Camera wiring: Try to avoid the phenomenon of wires with connectors. When installed in a building, it should be installed horizontally or vertically, preferably with casing protection.

(3) There are two ways to connect the camera tube, one is bright and the other is dark. Open piping should be horizontal, flat and vertical, with a good sense of design. Dark piping requires short pipes, smooth pipes and few elbows.

(4) The camera signal line should not be parallel to the high-power power line, nor should it be in the same tube.

(5) The AC power supply of the camera alarm control box should be wired separately. The camera should not pass through the same tube as the signal line and the low-voltage DC power line, and should strictly abide by the relevant design and industry standards.

(6) The wiring from the camera alarm control box to the ceiling needs to be protected by adding a set of management or using iron pipes in the wall to improve the anti-sabotage performance of the anti-theft system.
