How to extend the 12V DC power cable of the CCTV security camera?
Our wireless IP camera comes with a power cord, which is divided into 3 meters and 5 meters according to the type of camera. Generally, it can meet the use of most scenes, but in some cases where it is inconvenient to supply power nearby, if you want to install the location is far from the power supply location, and the original power cable is not long enough, what should I do? The original power supply will have a certain voltage redundancy. On this basis, we can use the DC power extension cable to extend the power supply distance.
What is a DC power extension cable?
A DC power extension cable is an electrical cable that connects a DC device and a DC power source. 電気を伝える電線です, 伝送方法はポイントツーポイント伝送です. DC power extension cable is also known as a DC power extension cord.
DC power extension cable applications
The DC power extension cable is typically used to supply power in low-voltage, low-current applications such as CCTV Cameras, routers, projectors, モニター, LED lamps, ソーラーパネル, Notebooks, 等. They are ideal for a situation where the power cord is too short for problems.

How to select the suitable DC power extension cable?
When choosing a DC extension cable, we need to pay attention to the following points:
1. Power interface size
The original power supply adopts a standard DC5.5mm*2.1mm male connector. The connector of the power adapter cable needs to be a DC5.5mm*2.1mm female connector on one side and a DC5.5mm*2.1mm male connector on the other side so that it can be matched normally.
ノート: A few brand camera power cord is 5 meters long, and the connector is a Mini interface, not a 2.1mm.
2. The material of the wire
The original power supply is made of pure oxygen-free copper material, with low resistance and low loss; if an external adapter cable is connected, additional loss and voltage drop will occur. If the voltage drop is too high, there will be insufficient power, and the camera will not be able to supply power normally.
したがって, choosing a material with a smaller electrical wire resistance is necessary. The resistance value (voltage drop) corresponding to our standard wire is as follows:
| Power Cable Material | 100m Resistance (Ω) |
| diameter 1mm copper wire | 3.1 |
| diameter 1mm copper clad aluminum | 5.6 |
| diameter 0.5mm copper clad aluminum | 19.1 |
| diameter 0.5mm copper clad silver | 12 |
| diameter 0.5mm copper wire | 8.4 |
| diameter<0.4mm copper clad aluminum | 46 |
| diameter<0.4mm copper clad metal | 144 |
| diameter 1mm copper clad aluminum | 5.6 |
| diameter 0.52mm copper wire | 8.3 |
したがって, we generally recommend using 0.5mm oxygen-free copper or better wire to reduce line loss as much as possible.
3. Length of cable
The original power supply cable is generally 3 meters/5 meters in length, and the standard DC power extension cables are 1/3/5/10 meters in length. You can choose extension cables of different lengths for power supply according to the needs of the actual scene.
(1) Common wire test
We use 0.5mm oxygen-free copper extension cables of different lengths for testing, and the test results are as follows:
Common wire test
| Original Power Cord | Cable Length | Total Length | Power |
| 9V 0.6A (3メートル) | 1メートル | 4メートル | Y |
| 3メートル | 6メートル | Y | |
| 5メートル | 8メートル | Y | |
| 10メートル | 13メートル | Y |
According to the actual measurement, the mainstream DC extension cables on the market can be used with our original power adapter to supply power to the camera to extend the power supply cable.
(2) Maximum extended distance test
We use a 20 メートル 0.5 sq.mm2 oxygen-free copper extension cable with the original power supply to power the camera, and the camera can normally work during the day and night.
