Correct Answer

Explanation
The correct answer is 2Mbps. This means that when a 720p video is recorded by ClickView 24-7 Cloud and available from Workspace, it will have a bitrate of 2Mbps. Bitrate refers to the amount of data that is processed per unit of time, so a higher bitrate generally results in better video quality.

The SD (standard definition) video recorded by ClickView 24-7 Cloud is recorded at 240p resolution. The bitrate refers to the amount of data that is transmitted per second in the video stream. The given correct answer of 400Kbps suggests that the video has a bitrate of 400 kilobits per second.

Correct Answer
B. False

Explanation
The answer is false because the video in the ClickView Library Server is in WMV format with a bitrate of 1Mbps, while the video in ClickView Online is in MP4 format with a higher bitrate of 2Mbps. Therefore, the video in ClickView Online will have a higher quality and bitrate compared to the video in the ClickView Library Server.
