Answer:
The unit integrates a 13.56 MHz Mifare RFID reader, a Bluetooth Low Energy (BLE) proximity module, and multiple relay terminals (2 inputs, 1 output). Relay channels can be triggered directly through DTMF tones dialed from SIP endpoints or indoor stations for electric door strike control.
The Onetouch OT-IP-VDP-C3 functions as both an IP intercom and an access reader station, integrating local authentication and lock release hardware on the terminal block:
- RFID Credentialing: Integrated 13.56 MHz Mifare contactless RF card reader for tenant badge scanning.
- Mobile Bluetooth Access: Built-in BLE (Bluetooth Low Energy) receiver for mobile proximity credential authentication.
- Access Control Interface: Features one standard Wiegand interface port for hardwired pass-through to third-party access control units (ACUs) and door controllers.
- Relay Configuration: Equipped with an onboard multi-relay interface configured with 2 relay inputs and 1 relay output for direct integration with electromagnetic locks, electric strikes, or automatic gate motors.
- Relay Actuation: Supports automated relay tripping and door unlock commands transmitted via dual-tone multi-frequency (DTMF) signaling from connected SIP handsets, mobile apps, or indoor monitoring terminals.
