JSK-RD035-V1.0 8 million 4K resolution 124 ° wide-angle distortion free automatic fixed focal width dynamic drive free USB output camera module chip board 38mm x 38mm x 26 / - 0.3mm, three infrared lamp interfaces are designed on both sides, we can choose whether to install infrared lamp according to the customer's needs. There are two screw holes on the chip board, and the lens is fixed on the PCB through these two holes. The important components that affect the lens parameters are mainly concentrated on the back of the SMD, including encryption chip, DSP chip, memory chip, some capacitors and resistors. The lens base is a plastic base. Black glue is applied to both sides of the lens to adjust the focus of the lens. It is required that the height of glue dispensing on both sides of the lens should not exceed 5mm, which is a qualified USB camera module.
