Many CCTV applications are in need of a lens that can quickly switch from capturing a broad view of an area to zooming in for a close-up look of distant objects when necessary. A few good examples include coast guard monitoring, highway traffic surveillance and border crossing security. The Tokina TM10Z0818AI is specifically designed for these purposes. Through the use of a compatible CCTV lens controller device, you'll be able to actively change the focal length on the lens from a wide view of 8mm to a telephoto view of 80mm, which translates into a 10x optical magnification. And with a name like Tokina, you can expect to get only the best, both in terms of image quality and lens durability.
Auto Iris Video
An auto iris function will permit the use of the lens in areas where light intensity changes over the course of a monitoring period.
