How to connect the surveillance camera cable?

Question 1: How many wires are connected to the camera? NPC camera, just plug the power cord into the socket.

Question 2: How to connect the five wires of the surveillance camera? The simplest method is to connect two red lines into a line and two black lines together, so there are three lines, the red line is connected to 12V+, the black line is connected to 12V- and the video line external network, and the yellow line is connected to the video line core. Make sure it works. Remember that red and black should be connected! !

Question 3: How to connect cables like a surveillance camera? Red and black are connected to the positive and negative poles of the power supply, and the remaining two messages are connected to the video.

Question 4: How to find the connection method of the surveillance camera? How to connect 8 wires? Urgent! Urgent! Urgent! Congratulations!

This is an electric three-variable lens that has been out of the rivers and lakes for a long time. Few people can use it in the market at present.

If I remember correctly, this camera should be 10 line.

Two are DC 12V power supply lines.

Two are video lines that connect images.

Six are lens control lines, which control zoom, aperture and focus respectively, and two lines for each function. One positive and one negative. If there are no instructions, we should try them one by one.

Connect any positive electrode with DC 12V power supply, and then connect the other five wires with the negative electrode to see which one reacts, which is a group.

After being divided into three groups, we can separate images according to whether they control magnification or aperture.

But aside from the key points, the usual camera is sharp, the imaging effect is not very good, it will be white, and people are not very clear. Is it necessary to pretend?

Question 6: How does the surveillance camera connect to the computer? You need to buy a video capture card (single channel or four channels optional) and install hardware and software drivers. The CD-ROM has operating instructions, 1 monitoring camera, a monitoring power supply, a set of bracket shields, several video poles and several power cables.

Question 7: How to install the power cord of the surveillance camera? Because the distance is not too far at 35 meters, I suggest scheme A, which is convenient for maintenance. Scheme C also needs to consider the waterproof safety of transformer.

There are two kinds of power installation points, one can be located in the monitoring point and the other can be located in the computer room.

If it is located at a monitoring point, such as Scheme B, the wiring cost is relatively low. Generally, the total power supply of 220V will pass, and there will be no problem with more than a dozen probes indirectly. Moreover, the transformer is close to the probe, so the current loss is low and the image correlation is stable. But near the monitoring point, it is sometimes troublesome to have a good place and a safe place to place the power supply, especially outdoors, which is easy to get wet by water. At this time, it's best to add a waterproof case for protection. But the maintenance is a bit troublesome, especially in high places or on the ceiling, climbing up and down, holding the ceiling, uncomfortable.

If the power supply is installed in the computer room, such as schemes A and C, the wiring cost is several times more (here refers to the optical power supply line), so it is a transformer, and the current of 12V is definitely unstable in the long-distance transmission process, and the better line may be relatively stable. This method is easy to maintain, and it is in the computer room. However, it is only applicable to close-range monitoring points or small-scale monitoring projects. Generally, DC is used, and long-distance power supply is preferably AC (100 meters or more). What I want to explain here is that some friends like to use network cables, which saves a little cost and makes wiring much simpler. One network cable, four sets of cables, one set of power supply, one set of video and one set of control. When you are lucky, there may be no big problem, but when the problem comes, it is quite troublesome. This kind is only suitable for close range, preferably within 30 meters. Some friends like to drag three or four probes on a 12V power supply, which is also undesirable.

Question 8: There are four wires and three wires connected to the surveillance camera. Generally, red is the positive electrode, black is the male terminal (negative electrode), yellow is the video line, and white is the audio line.

Question 9: What cable should I put to install the surveillance camera? If it is an ordinary camera, it needs a power cord (RVV2 * 1.0).

Video signal line (SYV75D5)

If it is with pan/tilt function, you need to add a control line (RVVP 2 * 1.5).

Question 10: How to connect the surveillance camera with a network cable? Just use the network cable directly for a short distance. I remember that there should be no problem between 40 and 70 (I use 20 to 30 meters as the longest). If you can buy a twisted pair transmitter, you need a pair for each camera. If the distance is more than 300 meters, you should use active starvation, and it is recommended that the front end be grounded. If you use a webcam or ordinary camera+digital module (this name is not allowed) to directly connect the crystal head+switch.
