Supplementary access control system for an rfid-controlled cat flap and method for supplementary access control using an rfid-controlled cat flap

A method for supplementary control of access through an RFID-controlled cat flap, wherein the RFID-controlled cat flap is configured to communicate with an RFID tag worn by a cat approaching the RFID-controlled cat flap, and to selectively enable an opening of the RFID-controlled cat flap comprising the following steps:

• detecting a cat approaching the RFID-controlled cat flap
• on the basis of the detection of the cat approaching the RFID-controlled cat flap emitting a radio-frequency interfering signal suitable to prevent an opening of the RFID-controlled cat flap;
• recording at least one image of the cat approaching the RFID-controlled cat flap
• on the basis of the at least one image, determining whether the cat is carrying a prey animal in its mouth;
• and
• on the basis of the determination that the cat is not carrying a prey animal in its mouth, terminating the emission of the radio-frequency interfering signal.

A supplementary access control system for an RFID-controlled cat flap, comprising:

• a sensor for detecting an approaching cat and a camera for recording at least one image of the approaching cat
• an image processing unit that is coupled to the camera and configured to determine, on the basis of the at least one image, whether the cat is a predefined, particular cat;
• a radio-frequency signal generator configured to transmit an identification signal, wherein the identification signal is suitable to enable an opening of the RFID-controlled cat flap and
• a control unit coupled to the sensor to the image processing unit and to the radio-frequency signal generator wherein the control unit on the basis of the determination of the image processing unit that the cat is the predefined particular cat, is configured to cause the radio frequency generator to transmit the identification signal.
