One potential d i f f e r e n c e w i t h multi-sensor cam- eras is that their bandwidth require- ments may neces- s i t a te a g i g a b i t Ethernet connec- tion. Depending on the manufac- turer and model s e l e c t e d , t h e s e cameras can range anywhere from 5MP to 40MP, so it is important to utilize the appropriate cable and switches to support the bandwidth. Also, with the higher megapixel cameras, you may experience a cap on the allowable frames per second (fps). It is important to keep this in mind when considering the level of detail or forensics required for the application. Licensing must also be reviewed to determine if a single license or individual licenses for each sensor will be required. Lastly, the mounting configu- ration and feature sets for these cameras will var y by manufac- turer and model. Whether you are requiring a fully weather resistant unit complete with heater and blower, a vandal resistant IK-10 I m p ac t u n i t , a w i d e d y n a m i c range or day / night solution, you should be able to find a multi- sensor panoramic dome to fit the application. Directional Multi-Sensor Dome The third type of panoramic cam- era is a multi-sensor megapixel camera with directional sensors. W hile providing the same 180° and 360° field of view as the pan- oramic multi-sensor camera, direc- tional multi-sensor cameras allow for each sensor to be individually adjusted and positioned to capture the desired field of view. This is achieved by using the four indi- vidual three-axis gimbals in the camera, which allow for the inde- pendent movement of each sensor. You can easily configure a direc- tional multi-sensor dome camera to provide a 270-degree field of view. This configuration is com- monly utilized for exterior build- ing corner mount applications, o r o t h e r a p p l i c a t i o n s re q u i r - ing unique ang les of coverage like parking garages where you may be trying to simultaneously obser ve the parking areas and vehicle entrance and exit lanes. Some manufacturers provide the option to mix and match different lens options to include vari-focal lenses with remote zoom and focus capabilities which provides even greater f lexibility. Due to the adjustability options for the sensors, these cameras are usu- ally much larger than both the panoramic single lens cameras and the multi-sensor panoramic domes. It is also impor tant to note that directional multi-sensor dome cameras are typically more e x p e n s i v e w h e n co m p a re d to other panoramic cameras. Conclusion Panoramic cameras are not the sin- gle answer for all applications, but when used correctly they can help round out a robust video solution. The process of selecting the right camera technology must start with a thorough understanding of the overall design objectives. If the design objectives include a require- ment for a high level of situational awareness over a relatively large field of view, panoramic cameras should be a top consideration. Due to the wide variety of camera choices and recording platforms, you will want to ensure you have done your due diligence during the design phase to make certain you have a cohesive and compatible system that meets all of the neces- sary requirements. ■
