Product Details
C20b: Iris Collection Comfortable & User-Friendly Dual-Eye
Capture Criminal Investigation
Description
C20b is your reliable partner in iris capture. Its sleek and
powerful design is built to provide an incredibly convenient way to
capture dual-eye iris images. Simply bring your eyes close to the
device, and you'll experience the ease and speed of iris image
capture.
In contrast to complex iris capture devices, C20b stands out with
its simplicity. It eliminates unnecessary complexities, simplifying
the iris capture process to a simple gesture. No more cumbersome
steps; just a blink, and your iris image is reliably captured.
C20b embodies the essence of dual-eye iris capture, allowing you to
tackle iris recognition challenges with ease, without the need for
a steep learning curve.
Product Highlights
- The device complies with the "Technical Requirements for Iris
Collection Equipment for Criminal Investigation Business" (used for
the construction of iris databases in the tens of millions for the
criminal specialized subsystem).
- High-quality iris image capture with a capture time ≤1 second.
- Supports dual-eye and any single-eye capture.
- Eye-mask design significantly eliminates the influence of external
ambient light on iris image capture.
- Rapid capture by bringing eyes close to the eye-mask, making it
simple and user-friendly.
- The eye-mask contact surface utilizes a combination of artificial
protein skin and sponge filling, ensuring comfortable and
user-friendly capture. It is also easy to detach and replace,
maintaining cleanliness and hygiene.
- Data filtering mechanism automatically prevents duplicate iris data
capture.
- Equipped with beauty contact lens detection.
- Supports simultaneous inspection of iris quality during the capture
process and provides quality check result prompts.
- Supports iris recognition for individuals wearing nearsighted or
farsighted transparent eyeglasses.
- USB 2.0 communication interface, plug-and-play, with enhanced
compatibility and faster data transfer speeds.
- Optional handheld or fixed bracket usage for convenience,
portability, and ease of use.
- Compatible with multiple system platforms, including Windows
XP/7/8/10, Linux, Android, and more.
