With the rapid development of network video surveillance and digital video processing technology continues to change, traditional infrared ip camera in recent years more and more to the development of network-based, high-definition direction. 07 years ago, some IP surveillance vendors began to launch early IP infrared camera. But in general this group of IP infrared camera only supports up to CIF resolution, there is no dual-filter design, infrared light is the most common technology is the product of the early experimental.
08,09 years, video coding processing technology and applications become more sophisticated, IP infrared camera support D1 resolution more appeared, and with the popularity of network
video surveillance more and more applications. This group of IP IR
camera with a professional LED infrared technology, infrared working
distance can cover 15 meters to 80 meters.
2010, with the rapid rise of high definition video
surveillance, a new generation of IP infrared camera - high-definition
infrared network cameras have begun to emerge, these cameras not only
the sharpness of the image to achieve the 720P, 1080P HD, but also uses
the latest generation of infrared light technology, with a high-end
dual-filter design.
In recent years, the rapid penetration of the network HD
technology in areas such as Green City, some of the more high-end
high-definition infrared network cameras more and more, such as
high-definition laser PTZ network cameras, the camera configuration 100 m
infrared laser light , 18 times the HD movement, safe city in high-end
products. In addition, high-definition infrared fastball,
high-definition infrared gun with infrared hemisphere is also developing
rapidly, the attention of a lot of IP surveillance manufacturer.
