SUPERIOR® Optics, is a leading and wide variety of CCTV Security Camera Lenses Manufacturers for CCTV Cameras. All of Box CCTV Camera Lens on this page can be used on our professional box CCVT cameras and our IP box security camera.
Security Camera Lenses come in many forms, including fixed focal manual iris, fixed focal fixed iris, varifocal, Monofocal, motorized zoom lens options, Megapixel lens, IR-sensitive lens, C-mount lens, CS-mount lens, micro lens, and pinhole lens ect.
Each security camera lens we offer provides unique functionality and is designed for different surveillance applications. Auto iris lenses are designed for outdoor use, or any applications with variable lighting conditions. Fixed iris lenses provide fixed focal length from super wide angle to telephoto depending on the camera format and intended application. Monofocal & Varifocal lenses are designed to meet a variety of applications, providing the flexibility to adjust between different focal lengths with a single lens.
100m, 500m or even 1km away objects can also be clearly displayed on the monitor. The decisive factor in this issue, in general, is the focal length of the security camera lenses, the longer the focal length, “see” the farther away, but at the same time the field of view is smaller, the results narrowed the viewing range.
In order to be able to more clearly detect the target within the scope of monitoring and automatic tracking, the general requirements of the target in the CCD target surface occupies at least three lines of television lines. To be able to distinguish the characters, the general should ask the person’s facial imaging in the 356mm (14in) monitor accounted for more than 12.7mm (0.5in).
In practical applications, the user often asks the camera how far an object is or how wide a scene can be seen. This should actually be decided by surveillance lenses, as well as the resolution of both the selected camera and monitor.
The focal length of the optical system is the distance from the main point of the optical group to the focal point. And surveillance lens is actually a combination of the composition of the focal length of the lens group, which determines the size of the image taken with different focal length of the security camera lens on the same location of the camera, with long focal length camera lens intake of the scene size Large, and vice versa, with a short focal length camera lens intake of the scene size is small.
