Tamron : DF020N0
Description
The DF020N0 is an HD Compact Zoom Lens with IR Cut Filter and Hall-effect Sensor Iris
The demand for mini-dome cameras has grown within the surveillance camera market, chiefly due to their installation efficiency and reasonable cost, and higher quality has been a requirement for the low-end 3″-class mini-dome cameras in recent years. Previous mini-dome cameras used Vari-Focal lenses that required the zoom and focus to be adjusted manually, requiring time and effort during installation in order to achieve precise focus adjustments in mega-pixel class cameras. The number of outdoor installations of mini-dome cameras has also increased, leading to a greater need for lens brightness and zoom functionality, as well as remote control operation.
Tamron’s new DF020 2-mega-pixel/Full HD/IR compatible compact zoom lenses are designed to meet these specific needs by delivering the convenience of zoom lenses but in a size that fits the low-end mini-dome chassis. In addition to the frequently used existing wide angle 3.0-9mm lens, a new 9-22mm medium telephoto lens of an equivalent size is now available, and both can be operated by remote control via networks. These products provide an all-new solution to mini-dome camera applications.
Features
→ Compact design that allows installation within 3″ mini-dome cameras:
The lenses feature a compact design that allows installation in low-end 3″ mini-dome camera bodies, ensuring compatibility with a wide range of camera markets.
The wide-angle, standard 3.0-9mm type and medium telephoto 9-22mm type lenses are approximately the same size, which allows them to be used in mini-dome cameras that use common platforms.
→ 2 Mega-pixel/Full HD compatibility, 9-22mm medium telephoto range, and F/1.6 aperture (Model DF020)
The lens covers a 9-22mm medium telephoto range for both indoor and outdoor monitoring.
Tamron’s proprietary optical design provides 2 mega-pixel/Full HD compatibility and high image quality from wide angles to telephoto ranges.
→ Compatible with remote control applications – A Stepper motor is used for focus and zoom. A lead-screw type motor with minimal backlash has been used for remote control operations via networks, which allows accurate control of the focus and zoom.
→ Maintains focus at night and under near-IR light conditions to deliver crystal clear image quality monitoring, 24-hours a day – Optical aberrations are corrected for visible and near-IR wavelengths, providing sharp, clear video images even at night when a wide range of different wavelengths are present.
→ Structural design that provides space for the mounting of near-IR LEDs
→ Peripheral resolution has been further improved compared to existing mega-pixel lenses
→ Image circle design that takes into co nsideration various CMOS sensor sizes
→ Environmentally – friendly design
