Product definition do very good, reaching more than 1100 lines, for example: in theThe structure has been greatly improved, all designed the analog video output terminal ( BNC ); in product design, manufacturers and practical engineering with aptly, of course there are some manufacturers need to replace the gasket mounting to solve hoisting and base problem; in the network time delay, product manufacturers more than more than 400 milliseconds delay rarely, it can be seen, the current high definition camera chip technology has been greatly improved; Shenzhen automatic three roller gateNetwork camera after 2011, stream control are also good, the same photographic digital chip, the camera stream set into 4M, high-definition network cameras clarity is good. But some manufacturers of stream control will be fluctuated problem, this is because the DSP digital signal processing ability. For high performance network camera, the main character is very excellent clarity and color, to ensure the high clear it is necessary to guarantee that the stream flow, which is contradictory, but there are some outstanding manufacturers in product hardware chip processing speed on the operation, with better function, generally using H.264 compression format, so the processing chip hardware processing speed is the decisive means. Shenzhen high rotating gate in the field of security monitoring, people are not content to see, more hope to see clearly, high-definition network cameras can meet this demand. Network camera also will be no delay, full high-definition, high sharpness, data without loss of direction. In 2011, high-definition network camera having such a breakthrough, believe in 2012, high-definition network cameras will lead the Chinese security industry to a higher level of development.
