What are the Charging Methods for Surveillance Cameras?

Generally speaking, surveillance cameras are what keeps them connected to a power source and thus keep them working without interruption. A camera without electricity and network refers to a camera device that does not require an external power supply and network connection and is still capable of monitoring and shooting. Its working principle mainly includes two aspects: solar power supply and wireless transmission. Then, of course, the charging equipment of the surveillance camera depends on different types, such as surveillance cameras without electricity and without network and wired network control. Although the charging method is similar, it will be different in the cloud. So follow our footsteps to explore the charging behavior of surveillance cameras!

The Type of Charging for the Surveillance Camera

Wired Charging

A wired camera refers to a camera that is connected to a video recorder or computer and other equipment through a cable to achieve monitoring, video recording and other functions. Its core components include cameras, interfaces, chipsets, etc., of which the camera is the main body responsible for shooting pictures. Wired cameras transmit signals to devices such as video recorders or computers through cables, enabling functions such as shooting, previewing, recording, and playback. Some charging cameras need to be equipped with many machines, and there are four power supply methods for wired cameras: independent power supply, centralized power supply, SPOE power supply and standard POE power supply. These power supply methods are the best way to charge some cameras. Generally, you only need to connect a power adapter.

Wireless Charging

The wireless camera does not need wiring, does not need a switch, and supports multi-platform viewing by the client. But lay out the power cord to plug it in. Of course, there are already wireless cameras on the market with their own power supply, but the battery life is limited, generally around two or three months. However, the device needs to be in the power supply state all the time during operation, so it is relatively better to choose the direct plug-in method. But there is a battery powered security camera, which takes keep long time to battery. So basically the choice of battery is depends on yourself.

Solar Charging

The so-called solar charging is a way to use the energy emitted by the sun to convert light energy into electrical energy to achieve the charging effect of the camera. It includes the solar panel, the body that holds the solar panel, the battery box, the movable bracket and the check diode. The battery box is integrated with the main body, and the movable bracket on the back of the main body is adjusted so that the battery plate is facing the sun. The positive and negative lead wires of the battery board are connected in series with the check diode and then connected to the positive and negative poles of the battery box respectively. The solar panel converts the sunlight shining on it into direct current and charges the nickel-cadmium battery through the positive and negative poles of the battery box. In fact, not only surveillance, but also cameras can be charged by solar energy, and many street lights on sidewalks are also used to generate electricity at night by using solar energy conversion during the day. People can fully conserve resources and make effective use of resources.


In general, no matter which charging method is used, the camera can be directly powered up, and the power supply state to the camera can also be achieved through energy conversion. Of course, with the continuous development of technology, there will be other camera types in the future, and other more efficient charging methods will also appear.
