The CMITech BMT-20 is a binoculars-type iris biometricsimaging device that quickly captures highest quality iris biometric images.Exceeding industry standards for image quality, this system optimizes matchingaccuracy, essential in very large scale deployments for which de-duplication isa core deliverable. Easy to use, the system can be reliably positioned by thesubject with minimal instructions, or by an operator with the aid ofpositioning feedback LEDs on the top of the imager's housing.
The patentpending optical design of the BMT-20 includesexpanded depth of field and a very large interpupillary distance range,providing effortless capture for subjects of all ages. Intended forapplications in which subjects have limited prior experience with biometricsdevices, the BMT-20 is ideal for enrollment programs of all sizes, includingthose involving very young children. Designed with the latest in optical andsystem control technology by one of the leaders in the industry, the BMT-20 isphysically robust, highly reliable and durable.
This system meets the elevated IP64 intrusion protectionstandard and is sealed against dust and other airborne particles to provideextended life in harsh environmental conditions. CMITech's products andtechnology are leading the industry in cost effective and easy to use irisrecognition solutions serving the full range of identification andauthentication use cases, including physical and logical access control,national identity, law enforcement, border crossing and immigration control applications.
