Working principle and remote control of camera

Camera, also known as computer camera, computer eye and electronic eye, is a kind of video input equipment, which is widely used in video conferencing, telemedicine, real-time monitoring and other fields. In this paper, the working principle and remote control mode of the camera will be discussed in depth to help readers better understand the equipment.

The light sensor controls the light.

The illumination of the camera is automatic. Monitoring the lighting of the camera, when to turn it on and when to turn it off, is based on the photoreceptor on the camera, which can sense the installation environment. In the dark environment, the photoreceptor will start the night mode of the camera and turn on the infrared light (white light and blue light) on the camera.

Digital signal processing chip

The optical image produced by the lens of the scene is projected on the surface of the image sensor, and then converted into an electrical signal, which is converted into a digital image signal after A/D (analog-to-digital conversion) conversion, and then sent to a digital signal processing chip (DSP) for processing, and then transmitted to a computer for processing through a USB interface, and the image can be seen through a display.

Remote monitoring camera

Remote monitoring camera is a remote monitoring camera, which is mainly divided into three types: normal version, enhanced version and outdoor version. It can rotate 320 degrees left and right and 60 degrees up and down for monitoring, taking photos and recording, and can also send photos and videos to a mailbox or FTP server. The camera has motion detection function and can be set to send e-mail for warning.

Remote monitoring without wiring

The most fundamental point of the remote monitoring camera of network people and traditional cameras is that you can remotely monitor the place you want to monitor anywhere in the world, without wiring or large-scale hardware assistance, as long as you use a network cable.

Low cost remote monitoring

Buying a webcam is easy to install (just plug in the network cable), without port mapping, with low deployment cost and remote monitoring.
