Pinhole cameras, also known as miniature cameras, have a lens hole as small as the eye of a pin and the camera body is roughly the size of a one dollar coin. When this type of camera technology is mentioned, people easily conjure up images of "voyeurism" and "undercover investigations" and the associated anxiety.
Indeed, surveillance is one of the main application areas of pinhole cameras. Due to their small size, wireless and excellent concealment, these cameras have their own advantages in the surveillance field. However, it should be pointed out that countries have relatively strict regulations on this kind of equipment, and only a few legitimate manufacturers can produce them, which provides citizens with a certain sense of security.
So what is the working principle of pinhole cameras? These cameras use lenses to collect light and project the light onto a photosensitive device. The photosensitive device converts the light signal into an electrical signal, and then these electrical signals are further converted into digital signals. These digital signals are compressed and sent to a monitor or recording device to realize the display or recording of the image. Due to size constraints, this kind of camera usually does not have many adjustment functions such as adjusting the focal length or adjusting the aperture. These cameras are mainly composed of multiple parts, including a lens, an image sensor, an analog-to-digital converter, and an image controller. If the camera has audio capabilities, it also contains components for collecting, processing, and transmitting sound.
While pinhole camera technology has advantages in the surveillance field, it is necessary to comply with relevant laws and regulations to ensure legal use.
