Can the camera be charged directly on the power socket?

Yes, you can. But from the point of view of safety and machine battery maintenance, it is best to use a special battery charger for charging.

At present, there are three charging methods for general civil flash DV:

A. Use the attached power adapter to charge the machine (in the off state);

B. Use the USB interface next to the hand strap of the fuselage (an extension cord can be added) to connect the computer (in the off state) to charge through the machine;

C use a special battery charger to charge;

There are many kinds of cameras and waterproof digital cameras, and the basic principle is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, that is, the "video signal" is obtained. The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.
