The all-purpose camera: AVT Prosilica GT
17 Oct 2011
The new AVT Prosilica GT camera series features a GigE Vision interface, specifically configured for outdoor applications at extreme temperatures (-10 °C to +60 °C) and changing lighting conditions. During development AVT aimed to reduce maintenance and repair efforts on site. The camera housing therefore incorporates cooling fins for optimum heat dissipation. An operating temperature control function transmits the camera temperature to the host system and switches the camera off automatically when exceeding a certain threshold temperature in order to avoid major damage. The Prosilica GT can even survive lightning strikes thanks to it's integrated Ethernet surge protection.
Latest sensor technology
The new cameras are equipped with the latest CCD sensors, including a range of Sony EXview HAD sensors. These sensors boast an impressive sensitivity even in the infrared range. The Prosilica GT is also available with the latest Kodak KAI CCD sensors which combine a high resolution and a high frame rate. The series with resolutions from VGA to 6 megapixel and frame rates of up to 119 frames per seconds will be extended by further camera models with high performance CCD and CMOS sensors.
Ideal for traffic and security applications
The Prosilica GT series comprises new features tailored towards demanding outdoor applications such as traffic and security monitoring, surveillance and aviation/space flights. The Precise Iris lens control (P-Iris) allows optimisation of depth of focus, exposure time and gain. DC Auto Iris-Standard enables use of economic lenses from the safety industry. The Precision Time Protocol (IEEE 1588) is used to synchronise cameras and other system components via an Ethernet network. And the Chunk Data function transmits meta data (gain and exposure settings as well as AOI) of the captured images. Image optimisation features such as gamma correction or lookup tables (LUT) prepare the image data for further image processing and thus reduce processing load at the host computer. The high frame rate of the Prosilica GT models allow for high speed burst images, often required for traffic control to capture multiple images of a passing vehicle and to determine its licence plate.
All Prosilica GT cameras feature a GigE Vision interface with Power over Ethernet (PoE), providing power supply and data transfer via a single cable. The Gigabit Ethernet interface with GigE Vision-Standard allows for a cable length of up to 100 metres using a standard cable. Longer distances can be achieved by means of switches or optical cables.
STEMMER IMAGING supplies these AVT cameras with the CVB 2011 CameraSuite MultiOS development environment.
