Many organisations consider implementing new video surveillance systems or even upgrading their outdated systems to make use of the recent technical improvements. There is a wide variety of security threats which businesses and other facilities have to face including theft by employees or visitors, violence, threats from outsiders and many other types of crimes. Each installation presents a unique coverage challenge in order to ensure that cameras are capable of providing useful images across all possible areas which require coverage. Multi sensor panoramic cameras provide many different benefits which can help organisations meet any unique challenges.
Multi Sensor Panoramic Cameras
PTX and fisheye cameras have been deployed for wide angle surveillance, however both of those cameras fall short of delivering on the need. PTZ cameras typically have a narrow focus which is not well suited for wide area surveillance as it requires multiple cameras to be deployed for full coverage, which is an expensive proposition which does not guarantee that these cameras will be pointed in the correct direction at the right time. Fisheye cameras provide a full 360° field view, however the combination of a round lens, rectangular image sensors and the requirement for de-warping technologies allowing the human eye to make sense of their circular images, can result in anywhere from 25 to 50% pixel loss.
Special imaging solutions based on their costs and bandwidth demands, improved multi-sensor panoramic cameras have emerged as a more effective alternative to both PTZ and fisheye cameras for wide area surveillance. These cameras incorporate multiple image sensors in houses, providing 180° or 360° panoramic views, overcoming the narrow focus of PTZs. Panoramic cameras apply advanced imaging algorithms to stich many images together, providing a seamless panoramic image without degradation and distortion which is common with fisheye cameras. New multi sensor panoramic cameras are quickly becoming an attractive option to provide wide area coverage.
Single multi sensor panoramic cameras can eliminate the requirement to install multiple single sensor cameras on the corners of buildings or parking lot poles, as multi sensor panoramic cameras have a wide coverage angle. Not only do they have an aesthetic appeal and reduce the cost of installing one rather than multiple cameras, they also offer greater Return on Investment (ROI) as they reduce the number of Video Management Systems (VMS) licences, which organisations require.
Multi sensor panoramic cameras can provide value at a corner of intersecting hallways and corridors, as the images captured by multiple camera sensors are stitched together, therefore blind spots are minimized and critical details are retained so that the entire flow of events is captured at once. This would save time for investigators as they would have less video to go through and would minimise risks, providing quicker remediation.
Multi sensor panoramic cameras which are installed above factory floors, cafeterias and other open areas with unpredictable traffic flows provide excellent situational awareness with extreme image detail. The imaging solutions are even more valuable when they are installed in conjunction with emergency call boxes, ATMs, visitor registration desks and other mission critical systems to capture and record valuable data for both security and business intelligence purposes.
High resolution, multi-image technology provides responding personnel with a wider field of view than standard IP cameras, which provides critical situational intelligence in real time. Some new models allow operators to zoom in to areas of interest while the camera continues recording the full field of view. Panoramic cameras don’t miss anything and can provide a video record of all events within their field of view.
Multi sensor panoramic cameras have earned their place in today’s surveillance systems, they are quickly becoming a core system component which advanced surveillance systems are built around. Surveillance professionals have certainly taken notice of benefits which these cameras provide, such as, greater coverage, higher image quality, lower Total Cost of Ownership (TCO) and increased ROI, which make multi sensor panoramic cameras an ideal solution for maximising safety and security in many mainstream applications.
