The output of the industrial camera interface

Industrial camera output interface type selection is mainly composed of need access to the data type of the decision. Different transport interface transmission speed, the length is different. If the image output directly to the video monitor, so only need analog output industrial camera. Industrial camera if you need to get the image transmitted to computer processing, there are a variety of output interface to choose, but must be in agreement and acquisition card interface, usually has the following several ways: 1. USB interface USB output digital image signal directly, serial communication, support hot plug, pull in 120 MBPS - transmission speed Between 480 MBPS, CPU resources. Transmission distance is short, easy to loose, stability is a bit poor. The current widely used USB2. 0 interface, is one of the earliest applications of digital interface, short development cycle, the characteristics of low cost. The downside is slow data transmission and data transmission process need to participate in the management, CPU occupancy resources, and the interface without screws, links easy to loose, the latest USB3. 0 interface USES a new USB protocol, can be faster to transmit data, but the USB3. 0 cameras on the market is not a lot. 2. Commonly known as firewire 1394 a / 1394 b interface, is the American institute of electrical and electronic engineers ( IEEE) Set a standard industrial serial interface. So is also called 'IEEE1394', is now mainly used for video acquisition, data transfer rate of up to 800 MBPS, support hot plug. Computer use 1394 interfaces need to use an additional acquisition card, use inconvenient, and because the early apple monopoly on the technology, market penetration is low, has gradually eliminated by the market. 3. Gige interface gigabit Ethernet interface, PC standard interface, it is the network interface, transmission rate and distance are higher. Is a kind of camera interface standards based on gigabit Ethernet communication protocol development, is characterized by fast data transfer rate and transmission distance of 100 meters high. Is the focus of the application on the market in recent years, easy to use, takes up less CPU resources, can be used more at the same time. 4. The advantage of the HDMI interface HDMI interface, HDMI can not only meet the resolution of 1080 p, also can support DVD Audio, and other digital Audio formats, supports 8-channel 96 KHZ or stereo digital Audio transmission 192 KHZ. HDMI EDID, DDC2B support, so it is of HDMI device has the characteristics of 'plug and play', between signal and display device will automatically 'consultation', automatically select the most appropriate video/audio formats. 5. Camera Link interface requires a separate Camera Link acquisition card, high cost, low portability, practical application is less, but is currently the fastest industrial Camera in the transmission, a transmission mode, generally in high resolution array Camera and high-speed linear array Camera application, is expensive. 6. VGA interface is the most common VGA interface, that is, we usually computer monitor connection between a host and VGA interface is a kind of type D interface, there are 15 needle above, divided into three rows, each row of five. Stronger and VGA interface scalability, can be easily transformed with DVI interface. There are gigabit network camera, HDMI camera, VGA camera series products, you can click here to industrial camera.
