Updated document as of August 5th 2022

While HELO supports standard USB and SD card media and encodes content to relatively low bit-rates (up to 20 Mbps), the instantaneous performance requirements of the media are significantly higher than that. This is especially true for longer file segment durations enabled by the v2.0 and above software update for HELO.

Longer duration files have larger headers, which require much higher burst performance during the beginning of each file. During recording, when HELO detects that the media is unable to keep up with recording speed requirements, a "Media Too Slow" alarm is shown on the web UI. This may result, eventually, in the recording being aborted.

Therefore, we recommend that you use relatively higher performance media. Please read the HELO Media Recommendations document for some general recommendations for managing media on HELO.
