A pet access system allows canines entry and exit through a portal based on a radio-frequency identification (RFID) signal transmitted from a device attached to the animal’s collar. Upon recognition of the unique signal, the system unlocks, granting passage. An example includes a unit installed within a door frame that activates only when a dog wearing the corresponding collar tag approaches within a specified range.
The primary advantage lies in enhanced security, preventing unwanted animals from entering the dwelling, unlike traditional flaps. This technology also offers convenience, eliminating the need for manual operation by homeowners. Historically, pet doors were simple, manually operated flaps. The evolution toward automated, selective entry reflects advancements in microelectronics and pet owner expectations for safety and ease of use.
