Allied Vision Technologies has introduced the Prosilica GT, a range of GigE Vision compliant digital cameras specially designed to perform in extreme environments and fluctuating lighting conditions.
Designed to minimise field maintenance, the Prosilica GT features a rugged thermal housing for maximum heat dissipation. It also offers remote temperature feedback with automatic power-down at peak temperatures to prevent critical component damage.
The Prosilica GT family features the latest CCD sensor technology, including a selection of Sony EXview HAD CCD sensors providing high sensitivity and excellent near IR response, and the latest Kodak KAI family sensors that combine high resolution and fast frame rates. Models from VGA to 6 Megapixels and up to 119fps at full resolution will be released in three phases, with the first models available in November 2011. Additional models featuring high performance CCD and CMOS sensors will be released in 2012.
The Prosilica GT cameras offer new advanced features well suited for outdoor installations such as ITS and traffic monitoring, public security and surveillance, military and space applications, as well as industrial inspection and machine vision.
Precise iris lens control allows users to select a fixed F-stop to optimise the depth of field, exposure time and gain; DC auto iris support enables low cost lens control for the security market; precision time protocol, IEEE1588 facilitates camera and peripheral device clock synchronisation across an Ethernet network; while chunk data offers metadata information with captured images such as gain, exposure or region of interest. Advanced colour processing, gamma correction and multiple LUT push applications even further by offloading host processes and allowing users to capture the most suitable image directly out of the camera. High frame rate capability offers burst image capture behaviour often required in a targeted event such as a passing vehicle in traffic applications where multiple images of a license plate improve ANPR accuracy.
All GT cameras feature Power over the Ethernet (PoE), a technology that supplies power along with image data through the camera's Gigabit Ethernet interface without the need for additional cabling.
