Theia Technologies CS-Mount 4-10mm F/1.4-Close 4K IR-Corrected Motorized Auto-Iris Varifocal Lens(Theia Technologies Cs Mount 4 10mm F 1 4 Close 4k Ir Corrected Motorized Auto Iris Varifocal Lens)

The Theia Technologies�CS-Mount 4-10mm f/1.4-Close 4K IR-Corrected Motorized Auto-Iris Varifocal Lens is designed for use with up to 1/1.7� sensors and offers motorized zoom and focus. Thanks to a compact design, it can easily fit into 4� domes. With an aperture range of f/1.4-close, the lens can be used for surveillance in low light as well as in bright conditions.�The lens is IR corrected for use with day/night cameras. This IR correction focuses IR light from artificial illumination at the same plane as visible light, allowing the image to remain in focus when the day/night camera switches to night mode.
