     Fixed focus lens is divided into standard and wide-angle lens two. The scope of application of fixed focus lens is as follows:

     Manual Iris Lens: The illuminance of the environment to be monitored changes little, such as indoors.

     Auto iris lens: Ambient illumination needs to be monitored for changes such as outdoors.

     Wide-angle lens: The surveillance angle is wider and closer.

     Standard lens: The angle and distance of monitoring are moderate.

     The zoom lens is divided into 10x, 6x, and 2x zoom lenses. The other divisions are: manual zoom and power zoom (electric aperture and auto iris).
