JSK-81M30S-V1.0 (K02) 2 million 1080p automatic focusing 100 ° wide angle 110dB wide dynamic USB output camera module chip size 60mm x 13mm x 17mm ± 0.3mm, both sides of the lens are fixed on the PCB board with black glue at high temperature. The size of COMS sensor is 1 / 2.7 "ft. its function can automatically gain reinforcement, adjust brightness and adjust white balance, and finally convert optical signal into digital signal. One end of PCB board is made of metal extension board, and two screw ports are reserved for fixing USB camera module. The front of PCB board is inlaid with DSP chip, memory card, encryption IC and output port. Finally, DSP chip processes the digital signal from sensor and transmits it to PC through the port.
