Usable in bright sunlight conditions
The BMT-20 is a binoculars-type, simultaneous dual iris capture
system intended for enrollment applications, especially very large scale
programs, in which subjects are presumed to have no prior experience in
providing iris biometrics samples. Developed for and proven in the
highly demanding India UID program, the BMT-20 offers the fastest
capture speeds, superior usability, minimal failure-to-captures rates
and outstanding image quality.
Most importantly, the instructions are easy to communicate, resulting
in a simple experience for operator and subject alike. The user is
simply directed to raise the BMT-20 to his or her eyes as if they were
binoculars, touching the forehead bar to the subject just above the eye
brows. Once the device is in position, they are asked to center their
eyes in the internal mirror while keeping them wide open their eyes. The
system does all the work of finding the irises and capturing pristine
iris biometrics samples. The BMT-20 is extremely efficient: once the
subject’s eyes are centered, the iris images are captured in 1.0 second
or less.
The BMT-20 features the largest depth of capture of any binoculars
type camera on the market. This capture range, a full 30 mm, covers the
range in the position of the iris relative to the forehead of the
entire population of adults and children down to 5 years old. This
means that all irises are within the focus capture zone when the BMT-20
is touching the forehead. By eliminating the need to reposition the
eyes during exposure, the system is consistently fast and highly robust
for large scale programs. It also offers the largest interpupillary
distance range of any device on the market of 40 to 90 mm, enabling
image capture on children, again as young as 5 years of age.
The BMT-20 meets the stringent requirements for IP64, which means the
device is highly resistant to contamination from the smallest of
airborne particles such as dust and dirt.
The system also includes an internal white LED that serves to constrict
subject’s pupil diameters to a consistent level, thereby improving the
quality of the enrollment image even in low light ambient environments.
