Which of these three schemes is better? It is very troublesome to connect the main outdoor power supply, and Plan B is very difficult to achieve.

Because the distance is not too far at 35 meters, I suggest plan A, which is easy to maintain, and plan C also needs to consider the waterproof safety of the transformer.

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

If it is set at the monitoring point, such as scheme B, the wiring cost is a little lower, generally, a 220V total power supply is used, and it is no problem to connect more than a dozen probes in the middle. Moreover, the transformer is close to the probe, the current loss is relatively low, and the image correlation is stable. However, in the vicinity of the monitoring point, to have a good location, the relevant safe point to place the power supply, sometimes more troublesome, especially outdoors, easy to be wet, it is best to add a waterproof wire box to play a protective role. However, maintenance is a bit troublesome, especially in high places or above the ceiling, climbing up and down, through the ceiling, it is not easy.

If the power supply is installed in the computer room, such as the AMagneC scheme, the wiring cost will be several times higher (here refers to the optical power cord), so that it is a transformer, a wire to the probe, and the 12V current must be unstable during long-distance transmission, and the better line may be relatively stable. This method, maintenance is more convenient, in the computer room. However, it is only suitable for close monitoring points, or small monitoring projects. DC is generally used, and AC is best used for long-distance (more than 100 meters) power supply. What I want to say here is that some friends like to use network cables, which saves not a little bit of cost, and the wiring is much simpler, one network cable, four sets of wires, a set of power supply, a group of videos, a group of controls. It may not be a big problem when you are lucky, but it is quite troublesome when it comes. This kind is only suitable for close range, preferably within 30 meters. Some friends like to drag three or four probes on a 12V source, which is also undesirable.

If the line is long, preferably 220 power supply to the camera in front of the transformer to 12 volts DC, if the long-distance transmission of DC 12 volts, it is estimated that it will affect the camera current. In fact, you don't have to worry about camera transformers outside, because today's transformers are waterproof.
