Answer:
The ZKTeco F09 features integrated SIP 2.0 video intercom capabilities with a built-in speaker and microphone, alongside advanced binocular visible light anti-spoofing technology to prevent unauthorized entry using photo and video playback.
Unlike conventional standalone attendance readers, the ZKTeco F09 combines physical access control, multi-biometrics, and IP communication into a single unified terminal:
- SIP 2.0 Video Intercom: Functions as a SIP client video door phone equipped with an 8-ohm 1W speaker and an omnidirectional microphone (-32 dB sensitivity, 2.2 kΩ impedance) for crystal-clear two-way visitor communication.
- Anti-Spoofing Facial Recognition: Utilizes dual-lens WDR binocular imaging and visible light algorithms to block counterfeit credentials, including printed photographs, digital screen replays, and 3D face masks.
- Dual Operational Modes: Features firmware switchable between AC Push (Access Control) and TA Push (Time Attendance) modes to match site architecture.
