What is the Maximum Recording Time?¶
RecDual Dongle has no built-in time limit for recording. The maximum recording time depends on your TF card capacity.
No Software Time Limit¶
RecDual Dongle does not impose a recording time limit
You can record continuously as long as storage is available
Recording stops only when TF card is full (or loop recording overwrites old files)
Recording Time by TF Card Capacity¶
Approximate recording times at 1080p@60fps:
TF Card Size |
Recording Time |
Notes |
|---|---|---|
32GB |
~2-4 hours |
Short sessions |
64GB |
~5-7 hours |
Daily use |
128GB |
~10-14 hours |
Extended recording |
256GB |
~21-28 hours |
Long-duration use |
512GB |
~42-56 hours |
Maximum practical capacity |
Times are approximate and vary based on video content complexity
Factors Affecting Recording Time¶
Content Complexity:
Fast-moving content (games, sports) = larger file sizes
Static content (presentations) = smaller file sizes
High-detail scenes use more storage than simple ones
Bitrate:
Recording bitrate affects file size
Higher quality = larger files = less recording time
Extending Recording Time¶
Use Larger TF Cards:
128GB or larger recommended for long sessions
256GB+ for all-day recording
Enable Loop Recording:
Automatically deletes oldest files when full
Enables continuous recording indefinitely
Configure in RecDual Link App
Manage Files Regularly:
Delete old recordings
Transfer files to computer
Keep TF card space available
Continuous Recording Considerations¶
For very long recording sessions:
Use quality TF cards - Reliable U3/V30 cards
Ensure stable power - For HDMI recording
Monitor temperature - Device may warm during long use
Adequate ventilation - Don’t cover the device
File Splitting¶
Long recordings may be split into multiple files
This is normal behavior for large recordings
Files play sequentially
With Loop Recording¶
Loop recording enabled:
Recording continues indefinitely
Oldest files deleted when full
Actual retention time depends on card size
Without loop recording:
Recording stops when card is full
REC LED turns solid blue
Must delete files to continue
