A microphone is installed outside the Sony camera. How to debug the settings inside?

Turn the switches CIH 1 and CIH2 in front of the two volume adjustment wheels to the input;

See which one your microphone is connected to (specifically 1 or 2);

In addition, turn on the +48v next to it to provide phantom power for the microphone.

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.

Camera equipment:

Photoconductive camera tube: lead oxide tube, selenium arsenic tellurium tube.

Solid-state photoelectric sensor CCD: the development trend is that CCD will replace camera tube regardless of broadcast level or business level.

Complementary metal oxide semiconductor CMOS: the technology is immature, the price and power consumption are lower than CCD, but the noise is large and the imaging effect is lower than CCD. High-tech CMOS is no worse than CCD image.
