placed on a table top. Due to its great sound receiving capabilities it is a great addition

to the Crestron CaptureLive HD experience; master sound volume range of -55dB to

+20dB, bass gain range ±15dB @ 100Hz, treble gain range ±15dB @ 10kHz and fre-

quency response of 20 Hz to 20kHz ±0.5dB. [20]

Essentially the Capture HD does what is claimed but during testing the Crestron Cap-

tureLive HD certain irregularities did occur in the promised features and capabilities of

the Capture HD. The first irregularities related to the streaming capabilities of the Cap-

tureLive HD; The CaptureLive HD is capable of streaming at high quality, 1080p, and

works well without much visible lag in the stream. At the start of a presentation a user

needs to decide whether to stream or record their lecture or meeting as the Capture-

Live HD lacks the capability to stream and capture simultaneously. The input screen

feed can be divided in several ways, via the touch-pad controller, giving focus to either

the computer screen, i.e. PowerPoint-slides, the camera feed, or side-by-side. Other

split-screen options are also available, such as adjusting the size and position of the

secondary screen. The split-screen options must also be made at the beginning of the

capture/streaming session as do all of the other settings. As mentioned before,

Crestron claims that the CaptureLive HD preview function of the capture or stream is

possible with the touchpad-controller; however, it could not be tested with the equip-

ment that was available to us. This was due to the fact that a camera with built-in

MJPEG-streaming capabilities was needed, or a separate Crestron Network Video

Streamer would be required, although the Crestron representative that provided the

camera assured that it would be 100% compatible with the equipment that we had.

The capture capabilities of the CaptureLive HD are on par with the claims that Crestron

has made. The CaptureLive HD captures with very good quality and seamlessly saves

the content onto a hard-drive or USB-flash drive, and as with the streaming function,

the screen can be split in several ways that must be determined prior to the start of the

session. Another function that both the streaming and capture features share is the

possibility to pause the feed, automatically creating a bookmark in the saved content.

The difference between the two is that in the content saved on a storage drive, the

bookmark results in the video crashing during playback, thus making it an almost use-

less function and making it a wiser decision to stop the capture completely and starting

again once the lecturer decides to proceed with the lecture. On the other hand, it is

possible to add bookmarks during the capture session via the touchpad, which does
