I want to know how many lines are required for a million high-definition surveillance cameras?

1. How many lines actually refers to the horizontal resolution of the analog camera;

2. Current network monitoring (or coaxial monitoring) uses pixels, such as 130W, 200W , 300W pixels, etc.

3. Because the clarity of analog surveillance is far inferior to that of network surveillance, the resolution of analog cameras on the market can only reach 60W pixels at most.

4. In addition, in addition to the so-called number of lines (or how many million pixels), the resolution of a camera also has other factors, such as whether the sensor uses CCD or CMOS. This is one of the reasons why the resolution of cameras with the same 700 lines varies greatly.
