Development Concept The demand for mini-dome cameras has grown within the surveillance camera market, chiefly due to ease of installation and increased cost-performance. Higher quality has also become a requirement for the low-end 3" class mini-dome camera in recent years.
Compact design allows installation within 3" mini-dome cameras
Previous mini-dome cameras have used Vari-Focal lenses that require manual zoom and focus adjustment. However, the need for more precise focus adjustment ability in Mega-Pixel class cameras has increased the amount of time and effort required during installation, creating a need for remote focus capability. The number of outdoor installations of mini-dome cameras has also increased, which has led to a greater need for remote zoom functionality. Tamron has developed a 2 Mega-Pixel/Full HD/IR compatible compact zoom lens to meet these needs. This new product delivers the convenience of a zoom lens in a size that fits the low-end mini-dome housing.
The zoom and focus can be remotely controlled using precision stepper motors, allowing implementation of continuous zoom and auto-focus functionality. The DC-iris is equipped with a Hall Effect sensor, providing position feedback to allow precise iris control. The integrated IR-cut filter switching mechanism can also be remotely controlled, allowing a smooth transition from day mode to night mode.
- The lens features a compact design that allows installation within low-end 3" mini-dome camera housings, ensuring compatibility with a wide range of camera markets.
2 Mega-Pixel/Full HD compatibility, 93°horizontal angle of view, and F/1.2 aperture
- The lens provides a 93° horizontal angle of view in wide and an F/1.2 aperture for monitoring under low-light conditions.
- Tamron's proprietary optical design provides 2 Mega-Pixel/Full HD compatibility from wide-angle to telephoto.
Compatible with remote control applications - Stepper motors and lead screws are used to drive the zoom and focus elements with minimal backlash, allowing precise control.
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 even in near-IR light, allowing sharp imaging at night.
Structural design provides space to mount near-IR LEDs
