Scanning
The rapid movement of the election beam in a pickup device of a camera or in the CRT of a television receiver. It is formatted in a line-for-line manner across the photo sensitive surface which produces or reproduces the video picture. When referred to a video surveillance field, it is the panning or the horizontal camera motion.

Schedule
Most of the system's operations are based on time and/or day of the week. The system can manage up to 100 different schedules. They are defined by the system administrator according to specific requirements (automatic unlocking, point monitoring, etc.). Each schedule can be composed of up to 4 different intervals (start-stop times) valid for any number of week days or holidays.

Score
A number indicating the degree of similarity or correlation of a biometric match. Traditional authentication methods ? passwords, PINs, keys, and tokens - are binary, offering only a strict yes/no response. This is not the case with most biometric systems. Nearly all biometric systems are based on matching algorithms that generate a score subsequent to a match attempt. This score represents the degree of correlation between the verification template and the enrollment template. There is no standard scale used for biometric scoring: for some vendors a scale of 1-100 might be used, others might use a scale of ? to 1; some vendors may use a logarithmic scale and others a linear scale. Regardless of the scale employed, this verification score is compared to the system’s threshold to determine how successful a verification attempt has been. 

Sensitivity (pickup device)
The amount of current developed per unit of incident light. It can be measured in watts with the projection of an unfiltered incandescent source of light at 2870 K degrees to the pickup device surface area. It can be then expressed in foot-candles.

Single Error Rates
Error rates state the likelihood of an error (false match, false non-match, or failure to enroll) for a single comparison of two biometric templates or for a single enrollment attempt. This can be thought of as a "single" error rate.

Serial Number
A unique combination of digits and/or letters. All system software (firmware) and hardware is serialized

Slave
A system unit that is programmed to be part of a network of systems and under control of a master system.

Smart Card
A card which incorporates a microprocessor chip and some form of storage. By extension, and in common usage, any form of chip card. A card containing a microchip that can store significantly larger amounts of data than a standard magstripe or proximity card. Bank account details, Social Security Numbers and employee identification numbers are examples of data that can be

Strike
A plate fastened to the door frame into which the bolts project.

Strike Box
A housing used in back of a strike to enclose the bolt or bolt openings

Submission
The process whereby a user provides behavioral or physiological data in the form of biometric samples to a biometric system. A submission may require looking in the direction of a camera or placing a finger on a platen. Depending on the biometric system, a user may have to remove eyeglasses, remain still for a number of seconds, or recite a pass phrase in order to provide a biometric sample. 

Synchronous Multimodality
the use of multiple biometric technologies in a single authentication process. For example, biometric systems exist which use face and voice simultaneously, reducing the likelihood of fraud and reducing the time needed to verify.
