Setup and Installation
Mounting Options
The R20K supports two primary installation methods:
- Flush Mounted: For a sleek, integrated look. Dimensions: 226x108x52 mm.
- Wall Mounted: For surface installation. Dimensions: 185x85x29 mm.
Ensure the mounting location provides adequate protection from direct harsh weather conditions, although the device is IP65 rated for water and dust resistance.
Power and Connectivity
The device can be powered via:
- PoE (Power over Ethernet): IEEE802.3af standard. This simplifies wiring by delivering power and data over a single Ethernet cable.
- 12V DC Connector: If PoE is not available, use a 12V DC power supply.
Connect the device to your network using the RJ45 Ethernet port (10/100Mbps adaptive). The R20K also features Wiegand and RS485 ports for integration with other access control systems, along with two relay outputs and two inputs for external device control.
Operating Instructions
Access Control
- Numeric Keypad: Visitors can dial a specific extension or enter an access code to gain entry.
- RF Card Reader: Present a compatible 13.56MHz (NFC) or 125kHz RF card to the designated area on the device for quick access.
Communication
- Two-Way Audio: Engage in clear voice communication with visitors. The built-in Echo Cancellation feature ensures high-quality audio.
- Video Monitoring: View live video feeds from the integrated camera on compatible indoor monitors or mobile applications. The camera provides clear images even in low light conditions thanks to high-intensity IR LEDs.
Integration
The R20K supports SIP and ONVIF standards, allowing it to integrate seamlessly with various IP PBXs, VoIP systems, and network surveillance systems.
Maintenance
To ensure the longevity and optimal performance of your Akuvox R20K, follow these maintenance guidelines:
- Cleaning: Gently wipe the device's surface with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
- Environmental Conditions: Ensure the device operates within its specified temperature range (-30°C to +65°C) and humidity range (10-90%). Extreme conditions can affect performance and lifespan.
- Firmware Updates: Periodically check the Akuvox official website for firmware updates. Keeping the firmware updated can improve performance, add new features, and address security vulnerabilities.
- Physical Inspection: Regularly inspect the device for any signs of physical damage, loose connections, or obstructions to the camera or microphone.
Troubleshooting
If you encounter issues with your Akuvox R20K, consider the following common troubleshooting steps:
- No Power: Verify that the power source (PoE or 12V DC adapter) is correctly connected and supplying power. Check network cables for PoE connections.
- No Audio/Video: Ensure network connectivity is stable. Check SIP/ONVIF configurations on both the R20K and the connected indoor monitor/PBX. Verify microphone and speaker settings.
- Keypad/Card Reader Not Responding: Check for physical obstructions. Ensure the device's firmware is up to date. For card reader issues, verify card compatibility and proper placement.
- Network Connectivity Issues: Confirm the Ethernet cable is securely connected. Check network settings (IP address, subnet mask, gateway) and ensure they are correct for your network environment.
- Intermittent Operation: This could indicate power fluctuations or network instability. Ensure a stable power supply and network connection.
If the problem persists after attempting these steps, please contact Akuvox technical support or your product reseller for further assistance.
