Dahua Technology, a global video surveillance provider, announces the adoption of Theia’s 4K lens family on its IPC-HF81230E Ultra HD Box Camera. Theia Technologies, LLC is an IP video surveillance lens specialist.4K Resolution Improves Video Clarity 4K resolution is a revolutionary breakthrough in image processing technology. Dahua IPC-HF81230E Ultra HD Box Camera delivers four times the resolution of standard HDTV 1080p cameras and offers superior picture quality and image details. 4K resolution considerably improves the clarity of magnified scenes, enabling the Dahua IPC-HF81230E Ultra HD Box Camera to view or record crisp-clear forensic video from large areas. With SONY advanced STARVIS image sensor which increases the pixel size to 1.85 µm, Dahua IPC-HF81230E Ultra HD Box Camera is capable of delivering 4K resolution video under lowlight environment. This makes the camera ideal for video surveillance applications that require low-illumination performance together with high definition. 4K Varifocal Lens Family Theia’s 4K lenses offer resolution performance matching the image quality promised by 4K sensor and provide good coverage of the larger 1/1.7”4K imagers. The varifocal lens family covers a horizontal field of view from 112 to 9 degrees, with the SL410 4-10mm lens and SL1250 12-50mm lens. The lenses maintain 4K resolution in Day and Night with less than 5 microns focus shift in near IR light. The lenses are extremely compact given their large format, at only 52mm long. Compared to other commonly found 1/1.7” format 4K lenses with similar features, they are much smaller, allowing them to fit into smaller enclosures. The lenses maintain 4Kresolution in Day and Nightwith less than 5 micronsfocus shift in near IR light At F/1.4 the SL410 boasts the fastest F number and likely the best light gathering ability of any 4k 1/1.7” format varifocal lens in the surveillance market today.

The SL410 and SL1250 varifocal lenses are designed to resolve 1.55 micron-sized pixel of smaller 1/ 2.3” 4K sensors Theia Technologies, the IP video surveillance lens specialist, will demonstrate its new range of 4K lenses on the upcoming Dallmeier 4K cameras at ISC West 2016 in booth 6051. The lenses are now available for sale just as 4K is beginning to accelerate. Theia’s new lenses offer resolution performance which truly matches the image quality improvements which the readily available 4K sensor cameras promise, but are not necessarily delivering. The lenses are designed to resolve the 1.55 micron-sized pixel of the smaller 1/ 2.3” 4K sensors, while at the same time resolving the 1.85 micron pixels and covering the larger area of the 1/ 1.7” 4K image sensors used in Dallmeier’s upcoming DF5400 Ultraline series 4K cameras. IR-Corrected Lenses The IR-corrected lenses are extremely compact given their large format, at only 64mm long. Compared to other commonly found 1/1.7” format 4K lenses with similar features, they are much smaller, allowing them to fit into smaller dome cameras such as Dallmeier’s planned 4.5” 4K vandal resistant dome cameras, as well as its box type versions. Theia’s family of 4K varifocal lenses will cover a horizontal field of view from 112 degrees to 9 degrees, with focal ranges of 4-10mm in Theia’s SL410 lens and 12-50mm in the Theia SL1250 lens. The new lenses will be offered in numerous configurations, including with motorized focus, zoom, IR cut filter, photo-interrupters, manual, DC auto and P iris options, as well as CS or D25 board mount versions. The SL410 4-10mm lens will also be available in a C mount version. Both lenses are in stock for immediate shipment.

So full 4K resolution optics are a key part of the puzzle required to achieve true 4k-compliant video in surveillance systems.” Mark Peterson, VP Advanced Technology, Theia Technologies, explained, “The emergence of 4K resolution in video surveillance will empower analytics-rich applications such as facial recognition, behavioral studies and ANPR, where a high level of detail and precision is required. The technology is also an obvious choice for situations in which there is a lot of activity or large areas where there are limited options for placing cameras yet the entire area needs covering such as in shopping centers, stadiums or open public spaces. “In these situations, identifying a person amidst a subject-dense scene is challenging at lower resolutions. We are excited to be on the forefront of this emerging trend and believe our lenses will set the standard that will enable adoption of this important technology.”
