May/June 2016 • SECURITY TECHNOLOGY EXECUTIVE 39 www.SecurityInfoWatch.com included a combination of multiple fixed view cameras installed along with select pan tilt and zoom (PTZ) cameras with the intent to fill any blind spots in coverage. While that design strategy is still valid for some applications, the relatively recent introduction of high resolu- tion panoramic cameras has changed the video system design landscape. Usually, these cameras fea- ture either a 360° or 180° field of view. 360° cameras are typically mounted at "ceil- ing " height and are pointed downward in the center of the area of interest to provide a 360° field of view. 180° cam- eras are typically wall mounted to provide coverage of areas to include exterior building facades, long corridors, large reception areas, etc. In either case, the cameras are capable of providing full fields of view with no blind spots. T h e m o s t c o m m o n p a n - oramic camera designs consist of either a single camera with a 180° or 360° extreme wide ang le lens or multi- s ens or cameras that include multiple camera sens ors and lenses in a single enclosure. A 360° multi-sensor camera usually will consist of four camera sen- sors with 90° lenses on each sensor. One advantage to this type of camera design is that the individual images are not optically distorted. However, special software is required to "stitch" the images together to provide the full field of view. The single lens cameras pro- vide a spherical "fish eye" type of image which is optically distorted and requires special software to "de-warp" the sig- nal to create a corrected and usable image. Some single lens cameras are designed with de- warping capabilities built into the camera and some require special software to be installed as part of the video manage- ment system. Generally speak- ing, the multi-sensor cameras can be two to three times more expensive, but provide a higher resolution and quality image when compared to the single sensor, wide angle lens designs. Applications and Trends Panoramic cameras have a potential application in any market where omnidirectional monitor- ing of large open areas is a requirement.
