Theia 4K lenses approved with Dahua 4K Box Camera
分享
 

Theia Technologies, the IP video surveillance lens specialist, announces that Dahua has qualified Theia’s 4K lens family for use on their IPC-HF81230E Ultra HD Box Camera. Theia’s 4K lenses offer resolution performance matching the image quality 4K sensor cameras promise, but don’t necessarily deliver due to inferior lens selection. Theia’s lenses resolve the 1.55 micron-sized pixel of the 1/2.3”4K sensors, while covering 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 <5 microns focus shift in NIR light. The 52mm lenses are more compact than comparable 1/1.7”4K lenses, allowing use in smaller enclosures and some domes. 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 CS mount lenses are available in manual, DC-auto or P-iris versions; fully motorized, board and C mount versions are also available. “When paired with Theia’s 4K lenses, Dahua’s IPC-HF81230E Ultra HD Box Camera is able to deliver very high image quality to the market enabling analytics and other high detail applications,” says Mr. Daniel Chau, Dahua Overseas Marketing Director. “When combined with Dahua’s recording solution, these 4K cameras provide video surveillance professionals with probably the most advanced imaging technology available.”

As Mark Peterson, VP Advanced Technology, at Theia Technologies, explained, “We are excited to cooperate with Dahua. 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.”
