Like the creation of many important inventions, the Iguana active tracing surveillance system was invented by Mr. Chaohong (Eric) Chang to answer an requirement by a local policy office for their surveillance video footages in the city. The active tracking surveillance video system was then invented with two cameras inside-- one with wide angle lens to take the scene of the spot for video analysis on the moving targets, and the second camera with telescopic lens with a moving mirror to take quick close-up picture of each object. The picture quality of the taken object can be improved up to 200 fold in this arrangement. The light-weight mirror is designed to response effectively to any referred location within the surveillance area.

With the patented two-camera and mirror machenism, Iguana system can track targets automatically without any human intervention. Instead of moving the telescopic camera to track, it is using the mirror mechanism to do the tracking. The whole process is completed seamlessly that rapidly responsed in less than 0.12 second.

Other than the typical speed domes or fast domes available in the world today, the Iguana auto tracking surveillance system is a much suitable and ideal solution for any large, complex, and high security required enviroments in application.
