Abstract
The housing and the camera of video security system are usually manufactured by different companies. During the combining use of camera and housing the main attention points are size, strength, power cord and video cable connecting method and their output channel; the optical matching is less considered and correspondingly poor image output occurs frequently. For improving the image output of video security system it is necessary to study the optical matching between the housing and the camera. VSS camera SCC-C6435 is one kind of indoor camera. SHG-222 is one kind of outdoor housing. The core of camera SCC-C6435 and the cover of SHG-222 are used to combine a new outdoor camera. But after this combination is finished the final image output is not good in some directions. Through measuring and analyzing we can know that the rotating center of SCC-C6435 lens does not coincide with the center of the cover of SHG-222, which is the basic reason of poor image output. After adjusting SHG-222 housing's inner structure accurately and combining them again, we can obtain perfect image output from the newly combined outdoor camera. After considering the optical matching between the housing and the camera we can improve the combined camera's image output greatly. It suggests that during combining one housing and one camera into one new camera with new function the optical matching is one important factor, and optical matching should be added as one important factor during housing design and camera design.
