By introducing this real day / night camera, CCTV cameras

 become more functional - and the lens must now meet the various lighting conditions for which they are aimed. When used with an infrared projector, the (infrared) correction lens provides a fully adjustable and clear focus image during the day and at night. This makes the infrared lens the best choice for a true day / night high-performance camera. Infrared lenses include 1 / 3-inch and 1 / 2-inch formats. The 1 / 3-inch lens is only used for 1 / 3-inch type cameras. The high design standard of the 1 / 2-inch lens makes it fully suitable for 1 / 3-inch and 1 / 2-inch type cameras. When used with a 1 / 3-inch type camera, a 1 / 2-inch lens provides a more powerful telephoto effect. For automatic aperture control, all lenses use a standard four pin EIAJ connector, which can be directly connected to the aperture output of the camera. Manual zoom lens is directly driven by DC diaphragm, while automatic zoom lens is equipped with video diaphragm drive. For zoom and pre positioning control, both lenses are equipped with an 8-pin DIN connector. The 18 times auto zoom lens also has the function of manual aperture control. Ed glass lenses, aspheric lenses and multilayer coatings create perfect optical quality. These lenses maintain a focal length of 950 nm infrared. The mechanical construction of the lens is very robust and can withstand frequent control operations for aperture, zoom and focus.
