Question

How do the Manual and Alarm Recording Modes work in the BVMS SDK?

Answer

This article clarifies the implementation and behavior of Manual and Alarm recording modes when using the BVMS SDK. This is particularly useful for users integrating recording controls into custom applications and observing unexpected behavior when attempting to start or stop recordings.

1. Manual mode via SDK

   • start (StartRecording) command works

   • start and stop time are identical

   • stop (StopRecording) command does not work, but does not return an error. Just take no effect.

   • recording terminates (recordingMode event of the camera) after post alarm time

    

2. Alarm mode via SDK

   • start command works

   • stop command does work

   • recording terminates after (command received + post alarm time)
