The high-speed digital camera and accessories is an analytical instrument used in the field of transportation engineering, which was launched on September 15, 2017. The camera housing is one of the components of the camera, which plays a protective role for the camera and is an important small device. The camera casing belongs to the security industry. Security is not for safety. There are many styles of camera casings. We can install different movements in the same casing, and we have different accessories for different movements. So we only order according to the size of the size. The lens of a digital camera is composed of multiple lenses, and the materials are divided into two categories: glass and plastic. If the digital camera lens is made of glass, many users and businesses say that the glass lens has better light transmittance and clearer projected images. However, many test reports have shown that glass lenses do not necessarily bring clearer images than plastic materials, and glass lenses may also increase the weight of the camera. From right to left, the lens assembly consists of a lens, an electronic shutter, a lens group 1, a lens group 2 and a CCD in sequence. The captured image is projected on the CCD along this optical path. The focal length adjustment system and shutter system in the assembly are composed of lens group 1 and electronic shutter, which are connected together. Driven by the motor, the lens group 997 and the electronic shutter can move back and forth to adjust the focal length, so as to obtain the clearest image, and the exposure is controlled by the electronic shutter. Multiple sets of lenses are used to complete the optical imaging, and the final CCD can convert the optical signal into an electrical signal.
