How to Check Your DVR Firmware Version

Your DVR's firmware version tells you what software is running on the unit. Knowing your firmware version is useful when troubleshooting, checking for updates, or contacting support.

Steps

1. Make sure your DVR is powered on and showing the live camera view
2. Press the blue Info button on your DVR remote
3. The System Info screen will appear on your monitor

The System Info screen displays your firmware version along with other useful diagnostic information about your DVR's current status.

Common Issues

The blue Info button is not responding

• Check that your remote has working batteries
• Point the remote directly at the DVR's IR receiver (small dark window on the front of the unit)
• Try pressing the button again from a shorter distance

The System Info screen appears, but all fields are blank

• Your DVR may still be starting up — wait 60 seconds and press the Info button again
