HD requirement
vedio image:
D1→720P→1080P
Sensitization technology
CMOS compared with CCD:
high pixels, high integration, low power consumption and low cost.
Chip technology
high-performance ISP chip, self-3A algorithm, real color reproduction and wide dynamic range
Real-time requirement
real uncompressed HD without image distortion
Digital requirement
Signal processing, transmission, storage, display, video analysis, linkage and integration between systems, etc.,all these put forward new demands to digital security monitoring .
