Cameras can capture what the human eye doesn’t always see, but only when they are setup and positioned correctly. One of the biggest challenges in developing an effective video surveillance system is eliminating the gaps in coverage between cameras, otherwise known as blind spots. Vumii, a maker of night vision cameras, has come up with a way to fix the problem. The Atlanta, Ga.-based company has developed a Web app based on the Google Maps API that enables users to asses a site and build a surveillance strategy based on the specific needs of a facility.
Intended for use by engineers, consultants and integrators, Vumii SiteBuilder lets you place virtual cameras within a satellite image or a map of an area to get a better understanding of a camera’s range and field of view. If a gap in coverage exists between cameras, you can spot it clearly on the layout.
The application lets you try out different combinations of camera settings (panning, tilting and mounting height), sensors and lenses to see their impact on the field of view. For instance, if you use a telescopic lens to zero in on the entrance to a building, your field of view is going to narrow and you may need to position other cameras nearby to eliminate gaps in coverage.
The surveillance planning tool also lets you emulate, at different ranges, the types of targets, such as people, vehicles and boats, you plan to keep a close watch on. Icons, videos, and text let you see the different uses of the company's infrared and thermal cameras. You also can build, save, and recall an unlimited number of site layouts.
SiteBuilder is useful in designing surveillance systems for special events, facilities, and military perimeters. It also comes in handy when designing surveillance protection for waterways, such as ports and coastlines.
