Dallmeier has selected Theia’s two new 5 megapixel lenses for use on the new 5 megapixel version of their DDF4900HDV dome camera.  In addition, the two lenses are now offered as optional accessories for use on all of their box camera lines.  

With the introduction of the Dallmeier’s 5 megapixel version of its DDF4900 HD dome camera, Dallmeier searched for lenses to optimize and complement the increased resolution benefits of its new dome camera and selected Theia’s new 5 megapixel offerings. 

According to Dr. Martin Theis, Team Manager for Camera Development at Dallmeier, “it has never been easier for me to be innovative and make our cameras more powerful than when using Theia’s megapixel lenses.  Finding great megapixel lenses at competitive prices that fit into our dome camera is an achievement made possible by Theia’s precision engineering and innovation.”  

Theia’s newest megapixel offering, the SL940A telephoto lens, provides full 5 megapixel resolution to zoom in and deliver high detail images. The IR-corrected, CS mount lens has a focal length of 9 to 40 mm, and is designed to let the user take full advantage of the ½.5” sensor used by Dallmeier’s new camera. And at a compact 50mm long, it easily fits in the dome profile.

In addition, Dallmeier has selected the new SL183 1.8 to 3mm, 5 megapixel, IR corrected lens with Theia’s patented Linear Optical Technology to provide up to 115 degrees undistorted horizontal field of view (HFOV), providing the opportunity to cover more area with a single camera, potentially reducing the overall cost of system ownership.  

Both new lenses offer a powerful combination of true megapixel resolution and IR correction in a compact envelope of only 50mm long. Theia’s lenses maintain crisp, clear megapixel resolution images making them perfect accessories for Dallmeier’s Cam_inPIX technology. This image processing technology developed by Dallmeier itself, whereby the picture information of every single pixel is digitally converted at the point of capture and is processed in the most optimal way, makes it possible to record clear, high-contrast and colour true pictures even in difficult lighting conditions. Digital noise reduction as well as numerous control functions like AWB, AGC or slow shutter, make further optimisation of the picture quality possible.
