CN SUPERIOR 2015 new products fixed CCD/CMOS super wide angle 1/4" 1.27mm m12 automotive camera lens

A5: 1) BFL is the distance between of the vertex of the last glass to sensor;

       2) Mechanical BFL is the distance between of the vertex of the mechanical parts to sensor.

A6: 1) At night in infrared light, the focal plance of position of the general lens will change, so that the image becomes blurred and has to be refocused to see clearly;

       2) IR lens use special design to reduce chromatic aberrations of the infrared light and visible light, so that the image are focused on the same position. The IR lens are also called night confocal lens and adapted to the market for 24 hours monitoring.

A7: IR-CUT dual filters comprise two parts: filter + controller.

In the daytime, the IR-CUT filter switch works, and then the CCD restore the true color. In low light night, the IR-CUT filter automatically removes and the whole spectrum filter works to make full use of the light in CCD, greatly improving the low light performance.

A8: P-IRIS is a new automatic, aperture controller. Be different with DC-IRIS, the main task of P-IRIS control is not constantly adjusting traffic light passing through the lens. The main purpose of P-IRIS is to set the best iris position to make best use to the most of the center of the lens so that improving the image quality. This position is called the depth value where getting the best use of the lens, optical errors greatly reducing, the best image quality can be obtained(in contrast, resolution and depth of field area). This is the default setting of the IP camera with P-IRIS.

A9: For small order, express will be best. And for bulk order, sea ship way is best but take much time. For urgent orders, we suggest via air to airport plus our ship partner send to your door.
