A, camera (CAMERA or WEBCAM), also known as computer camera, computer eye, electronic eye, etc., is a video input device, is widely used in video conferencing, telemedicine and real-time monitoring. Ordinary people can also talk and communicate with each other over the network with images and sound through cameras. In addition, people can also use it for a variety of popular digital imaging, audio and video processing.
Two, the camera can be divided into two categories of digital cameras and analog cameras. Digital cameras can be video capture devices to produce analog video signals into digital signals, which in turn will be stored in the computer. Analog camera to capture the video signal must be specific video capture card to convert the analog signal into digital mode, and compression can be converted to computer use. A digital camera captures the image directly and then transfers it to the computer through a serial, parallel, or USB port.
Three, the computer market camera is basically based on the digital camera, and digital camera in the use of new data transmission interface USB digital camera is the main market, most of the visible are such products. In addition to this there is a video capture card with the use of products, but not yet mainstream. Due to the rapid popularity of personal computers, the overall cost of analog cameras is high, and can not meet the BSV LCD splicing screen interface and other reasons, the USB interface transmission speed is much higher than the serial port, parallel port speed, so the market USB interface digital camera.
Four, analog cameras can be used with video capture card or USB video capture card supporting the use of the computer is very easy to connect with the use of typical applications is the general video surveillance. The clean area camera, clean area embedded special camera is for the clean area clean room important equipment key positions in real-time monitoring of the special camera. The camera flat panel, embedded in the color steel plate installation, zero health dead ends, easy to clean, easy to install, fast multi-point control, compatible with mainstream video systems.
Fifth, the camera (webcam) generally has a video camera / dissemination and static image capture and other basic functions, it is by the lens to capture images from the camera light-sensitive components within the circuit and control components of the image processing and converted to digital signals that can be recognized by the computer, and then by a parallel port or a USB connection input to the computer by the software and then image restoration.
Six, remote monitoring camera is a remote monitoring camera, the main version of the ordinary version, enhanced version and outdoor version of the three categories, you can left and right 320 degrees, up and down 60 degrees rotating monitoring, the screen for the picture, video recording, and can be sent to the mailbox, video or FTP servers, the camera has a motion detection function, you can set up to send an e-mail warning, and so on. The most important thing is that there is no need for wiring, no need for extensive hardware support, just a network cable, you can monitor any corner of the world remotely to the place you want to monitor.
