Let the professionals come ~ I really want to know the difference between the camera module of mobile phone and the camera module used for monitoring. Lens, sensor, DSP, output, etc ~

The basic structure is similar, including lens, filter, sensor and ISP module. But the materials of mobile phones and surveillance cameras are different in some ways.

1. Lens and filter

Limited by the size of the mobile phone, there is generally less monitoring.

2. Sensor

Similarly, due to the limitation of cost and size, mobile phone sensors all use CMOS, but there are surveillance cameras, CCD and CMOS cameras. CCD is the biggest choice for high-quality and high-resolution imaging.

3. Image processing module

Mobile phones are generally completed by proprietary chips, and surveillance cameras are generally programmed with FPGA or ARM.

The surveillance camera is usually a fixed scene and fixed focus application, but there will be a focus motor on the mobile phone to assist autofocus.
