What are the differences between HVIDEO and EVIDEO commands (JC400/JC261)?
Answer
Both commands are used to request video files from the server. Meaning, when you search for a specific video clip, either command can be used to retrieve it.
However, the key difference is where the video is sourced from:
HVIDEO retrieves the video from the camera’s sub-stream, which is encoded at a lower quality. Additionally, due to recent firmware updates (FW + 1.6.3), the number of days available through the sub-stream has been reduced.
EVIDEO extracts the video directly from the SD card, which provides higher video quality but may require more data consumption during upload.
In summary, HVIDEO offers faster, lower-quality retrieval from the sub-stream, while EVIDEO provides higher-quality footage directly from the SD card at the cost of increased data usage.
