What does 'RFID' stand for in the context of gate access control systems?
Answer: Radio Frequency Identification
RFID stands for Radio Frequency Identification, the technology used in proximity key cards and fobs to wirelessly communicate credentials to a gate reader.
What is 'tailgating' in the context of access-controlled gate security?
Answer: An unauthorized person following an authorized person through a gate before it closes
Tailgating is a security vulnerability where an unauthorized individual slips through a controlled access point immediately behind an authorized user.
What is the primary advantage of a dual-factor access control system (keypad plus card reader) over a single-factor system at a gate entry?
Answer: Increased security by requiring both something the user has and something they know
Dual-factor authentication requires two distinct credentials—typically a physical card and a PIN—making unauthorized access significantly harder to achieve.
Which device allows vehicles to exit an automated gate without presenting any access credential?
Answer: Free-exit loop detector
A free-exit loop detector uses electromagnetic induction to sense outbound vehicles and automatically triggers the gate to open without requiring credentials.
What is the purpose of an intercom system integrated into a gate entry access control system?
Answer: To allow voice or video communication between a visitor and the property occupant before granting access
Integrated intercoms enable the property occupant to verify a visitor's identity through voice or video before remotely releasing the gate latch.
When running access control wiring for a gate operator over a long distance, which cable type is typically specified to minimize signal loss and interference?
Answer: Category 5e or 6 (Cat5e/Cat6) or shielded low-voltage cable
Cat5e/Cat6 or shielded low-voltage cable provides proper shielding and twisted-pair construction that minimizes electromagnetic interference and signal degradation on long runs.
Which type of access credential requires no physical token or memorized code, instead using a unique biological characteristic to grant gate access?
Answer: Biometric reader (fingerprint or facial recognition)
Biometric readers authenticate users based on unique physiological traits such as fingerprints or facial geometry, eliminating the need for a physical credential or memorized code.
