TetherBox 5 External Drive Requirement

TetherBox 5 high-channel models require external storage for video recording. This guide explains why and how to set it up.

Why External Storage?

TetherBox 5 is available in multiple configurations:

  • 2-channel model: 1TB internal SSD (no external drive needed)

    • TetherBox 5 2-channel unit
  • 4-channel model: Requires external 2TB+ drive

  • 8-channel model: Requires external 4TB+ drive

High-channel models generate significant data volume. External drives provide:

  • Increased storage capacity
  • Better performance through dedicated I/O
  • Easy expansion and upgrades
  • Quick drive replacement if needed

Setup Process

Requirements

  • USB 3.0 external hard drive or SSD
  • Minimum capacity: 2TB (4-channel) or 4TB (8-channel)
  • Connection: USB-A port on rear of TetherBox

Installation Steps

  • Power down your TetherBox and connect external drive via USB-A port on rear

    • TetherBox storage setup mockup
  • Power on the TetherBox and navigate to Admin > TetherBoxes > [Name] > Storage tab

  • Format & Enable the external drive (this erases any existing data)

  • Wait for format to complete and TetherBox begins recording to external drive

Danger: Formatting will permanently erase all data on the external drive.

Verification

After setup, verify the drive is recognized:

  1. Go to Admin > TetherBoxes > [Name] > Storage tab
  2. Confirm external drive appears with correct capacity
  3. Check recording status and storage usage
  4. Verify cameras are recording to the external drive

Considerations

  • Drive format: Keep the drive dedicated to TetherBox (don't share with other devices)
  • Connection stability: Ensure USB cable is secure to prevent accidental disconnection
  • Capacity monitoring: Monitor storage usage in admin panel to plan upgrades
  • Power management: External drive gets power from TetherBox USB port (usually sufficient)

If the external drive fails, you can temporarily use the internal 256GB SSD while waiting for a replacement. Recording stops once full.
