In each of the four training rooms audio visual experts, Castle Grange Technologies, installed two Optoma ProScene EH505 projectors with short throw lenses. These were edge blended together with the powerful image blending and warping processor, Chameleon GB200 to create a huge 5.4m wide seamless image.
The imagery is projected straight onto the wall, which was painted with high gain projection paint. The eight projectors were installed at only 1.8m from the wall to eliminate any shadows from firefighters as they undertake the exercises. They were linked to external speakers via the audio output to provide the sights and sounds of real-life scenarios that firefighters may face.
The remaining EH505 projector was installed with a standard throw lens in the main lecture theatre to show videos and de-brief presentations following the training sessions.
The 5,000-lumen EH505 projector with WUXGA resolution and powerful image blending tools delivers spectacular image quality and outstanding brightness – ideal for the training rooms.
It has multiple lens options, with zoom and focus adjustment to get the exact image size needed, while the wide lens shift range gets the image exactly where it is wanted. This combination of zoom, lens shift and choice of lens ensured that installation was straightforward.
All Optoma projectors use DLP technology, pioneered by Texas Instruments. This uses millions of mirrors to produce high quality imagery which does not suffer colour degradation over time, as sometimes experienced in other projector technologies. The dust-sealed, filter free design prevents dust and dirt from affecting the system ensuring optimal image quality with minimal maintenance. With full support for Crestron, Extron, AMX, PJ-Link and Telnet LAN commands, the projector can be controlled and monitored remotely over a LAN.
Ideal for museum installations, tourism attractions and exhibitions, the Chameleon GB-200 can merge the overlapped edges of two or more projectors to create one seamless image. It provides a simple and fast solution to an otherwise complicated and labour intensive procedure and has two channels, so a single processor can serve two projectors.
It includes both black level uplift and multi-region colour correction, which makes matching multiple projectors quick and easy. In addition, it allows sub-pixel control of the alignment of both images with up to 289 individual points of adjustment on each projector enabling use on both flat and curved surfaces.
The Chameleon can also be used for stacking, when a project needs higher lumens. Stacking overlays images from multiple projectors to produce a higher brightness.
An Optoma HD300X projector was installed in each of the two smaller and conjoining lecture rooms, separated only by a retractable wall. This solution installed gives the fire service the option of using both rooms as one lecture theatre by retracting the wall. Due to the precision of the install, the 1,600 lumens of brightness and the projector’s Full HD 1080p image quality, the presentation can be viewed clearly from all angles.
