HVIDEO vs EVIDEO commands

Question

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.
