What about the pixels of BS-483S-30 camera? How clear is it?

This is the internal identification number of the product, not the brand.

Generally, it is 1/3 inches, and the definition is better in the camera. The concept of pixel number is meaningless, because there is more than one type of camera BS-483S-30 (it is Sony's CCD, but many manufacturers will use it), and the pixels of different manufacturers are different, most of which are 2 million pixels. But the definition is the same (high pixels are the result of interpolation).

Its lateral clarity: 480 lines (slightly higher than the average).

Generally speaking, it's not bad.
