Abstract
A system enables a scheduled visitor to receive an optical credential in paper or electronic form, and a range of date-time validity for a video doorbell which may actuate a portal. Upon activation the video doorbell hashes the optical credential with the date-time of the actual access request, masked to a range of most significant bits to create a plurality of digital bit-keys. The bit-keys generated exclusively at that video doorbell at that time would be verified with a stored digital bit-lock which is a complementary transformation of the valid date-time range hashed with the original optical credential at a visitor filtration server. Overwriting a stored digital bit-lock in a video doorbell at any time effectively cancels access by that optical credential. An emergency access key phrase communicatively couples the video doorbell with a visitee interview panel overriding access policies. Installation of custom software on the visitor's terminal is unnecessary.
