EverFocus Selects Theia's Megapixel Lenses for Its New Cameras
EverFocus Electronics Corp. has selected Theia’s new megapixel auto-iris lenses for use on the EQH5200 series HDcctv and EAN3200 series IP cameras that will be released at ASIS, in Orlando, Fla. from Sept. 19 to 21. The two lenses, along with Theia’s SY110A lens are now offered as optional accessories across EverFocus’ portfolio of megapixel box cameras. Theia will demonstrate its newest offerings in booth 1864 at ASIS.
With the introduction of EverFocus’ megapixel HDcctv and megapixel IP cameras, EverFocus searched for lenses with the optical clarity and focal range to allow full use of the 2-megapixel imaging capabilities of its EQH5200 series HDcctv and EAN3200 series IP cameras and selected Theia’s new megapixel offerings.
“In addition to superlative image clarity, to fully leverage the capability of megapixel cameras to deliver greater pixel/foot resolution, virtual pan/tilt/zoom and the inherent ability to cover much larger areas with a single camera, one requires distortion free lenses with very short focal lengths for wider views,” said Alan Schwartz, HDcctv product manager at EverFocus. “Theia’s unique technology creates ultra wide views without the fish-eye effect one would normally expect from focal lengths of less than 2 millimeters. The end result eliminates any need to compromise image quality to achieve the benefit of lower equipment cost per foot or degree of covered field of view.”
EverFocus has selected Theia’s new SL183 1.8- to 3-millimeter, 5-megapixel, IR corrected lens with the patented Linear Optical Technology to provide up to 115 degrees (depending on sensor) undistorted horizontal field of view (HFOV), providing the opportunity to cover more area with a single camera, potentially reducing the overall cost of HDcctv and IP system ownership.
In addition, 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 millimeters and is designed to let the user take full advantage of the 1/2.5- and 1/3-inch sensors used by EverFocus’ new cameras; and at a 50 millimeters long, it is aesthetically pleasing when the camera is in view or easily fits within conventional camera housings.
Both new lenses offer a combination of true megapixel resolution and IR correction in a compact envelope of 50 millimeters long. Theia’s lenses maintain crisp, clear megapixel resolution images making them suitable accessories for EverFocus’ HDcctv and IP 2-megapixel camera technology. With 2.7 times the horizontal pixels of a traditional standard definition image, HDcctv and 2-megapixel IP cameras offer the opportunity to replace up to five SD cameras and DVR ports with two HDcctv cameras and ports, or with two 2-megapixel IP cameras and NVR camera cameos/licenses while achieving the same resolution in the field of view as an SD image, all else being equal. EverFocus will demonstrate its EQH5200 series HDcctv and EAN3200 series IP cameras with Theia’s lenses at ASIS in booth 1049.
Theia’s SY110 1.7-millimeter fixed focal length lens provides up to 120 degrees HFOV without barrel distortion using Theia’s Linear Optical Technology with 3-megapixel resolution and IR correction, at a more modest budget.
Theia’s Linear Optical Technology provides an ultra wide field of view through all-optical distortion correction that removes barrel distortion without using software. Compared to typical wide angle lenses, Theia’s technology increases resolution at the edges of the image improving the ability to recognize subjects.
