The detail in an image is determined by resolution. The shorter the lens focal length, the wider the field of view. Greater than about 90 degrees most lenses start to show curved, barrel distorted images that compress the image at the edges. Rectilinear lenses such as those using Theia Technologies’ Linear Optical Technology™ don’t exhibit barrel distortion and thus maintain image resolution out to the edge of the image.

Megapixel Video for D.U.M.I.E.S., Part 1 Gang way, the Megapixel Revolution is upon us! No, it’s not the latest “Transformer” movie blockbuster but rather the coined phrase signifying the arrival of superior video surveillance technology. This, the first of a four-part series, has been designed to transform you into an expert on the topic.

Understanding IP Video for D.U.M.I.E.S., Part 1: Networked video surveillance systems are at the forefront of the convergence of IT and physical security.However, no matter what the delivery method, the proven, time-tested principles of CCTV system design remain vital. Applying these theories to IP-based systems can help overcome some inherent shortcomings.

Understanding IP Video for D.U.M.I.E.S., Part 2: Whether a system is analog, hybrid or entirely IP-based, it’s all for naught if the camera fails to capture quality images.While it’s true many of the optimizing principles of older analog cameras apply to their IP successors, the technology introduces enough new wrinkles to keep even the most skilled integrators on their toes.

Understanding IP Video for D.U.M.I.E.S., Part 3: As the size of broadband pipelines continue to increase, the amount of data seems to expand right along with them.Therefore, the bandwidth consumed by IP video system transmission continues to be paramount. Fortunately, there are numerous compression solutions available to help.

Understanding IP Video for D.U.M.I.E.S., Part 4: Deploying IP cameras necessitates not only an indoctrination of networking concepts, but also a firm grasp of analog video and how to translate those design principles into the language of digital surveillance. Sizing up an application calls for equal consideration of a range of factors, such as purpose, location, light, bandwidth and image size.
