±2°Company InformationFAQ Q1: What is the Warranty for the m12lens?A1: For the lens, we have 2 years warranty. If any quality problems on our side occured in this period, we will take on the shipping cost and replacement. Q2: What is Focal Length & Depth of Field & Filed of View?A2: Focal lenght is the distance over which initially collimated rays are brought to a focus. Depth of field is the distance between the nearest and farthest objects in a scence that appear acceptably. In the optical instruments, by the lens of the optical instrument as the vertex, the maximum range of two edge lines which the measured targes's images can shoot through the lens is called the field of view. Q3: Whatdoes Manual Iris Lens andAuto-Iris Lens meanmean?A3:Manual iris lensesprovide an effective solution for applications where the scene and lighting requirements are relatively stable, especially when used with security cameras that are equipped with electronic shutters.Auto iris lensesproduce consistent video signals in scenes with varying light levels, thus enabling reliable surveillance in areas that would otherwise be compromised. Q4::What is CS mount & C mount?A4: The flange distance of the CS mount lens is 12.5mm, applying to CS mount camera, but C mount camera. The flange distance of the C mount lens is 17.5mm. The lens to the camera with C mount can also be used for the CS mount camera, jsut add a 5mm lap(adpater ring). Q5: What is BFL & MBFL?
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. Q6: What is the difference of the IR lens and general lens?
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. Q7: What is IR-CUT?
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. Q8: What is P-IRIS?
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. Q9: Is there cheap shipping cost to import to our country?
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. Q10: Can we get support if we have our own market position?
A10: Please inform us your detailed mind on your market demand, we will discuss and propose helpful suggestion for you, to find the best solution for you.Our Services
