The CMITech BMT-20 is a binoculars-type iris biometrics imaging device that quickly captures highest quality iris biometric images. Exceeding industry standards for image quality, this system optimizes matching accuracy, essential in very large scale deployments for which de-duplication is a core deliverable. Easy to use, the system can be reliably positioned by the subject with minimal instructions, or by an operator with the aid of positioning feedback LEDs on the top of the imager's housing.

The patentpending optical design of the BMT-20 includes expanded depth of field and a very large interpupillary distance range, providing effortless capture for subjects of all ages. Intended for applications in which subjects have limited prior experience with biometrics devices, the BMT-20 is ideal for enrollment programs of all sizes, including those involving very young children. Designed with the latest in optical and system control technology by one of the leaders in the industry, the BMT-20 is physically robust, highly reliable and durable.

This system meets the elevated IP64 intrusion protection standard and is sealed against dust and other airborne particles to provide extended life in harsh environmental conditions. CMITech's products and technology are leading the industry in cost effective and easy to use iris recognition solutions serving the full range of identification and authentication use cases, including physical and logical access control, national identity, law enforcement, border crossing and immigration control applications.
