5 Configure crowdbeamer
Temperature
Current temperature of the device.
Charger connected
Indicates whether crowdbeamer is connected to the mains power supply.
Battery level
The current battery charge level.
Maximum number of clients
The maximum number of clients possible with the current edition (page 13).
Connected clients
These two numbers show the total number of clients (audience) connected to crowdbeamer
private WiFi.
The two numbers show (number connected to the 2.4GHz frequency) / (number connected to the
5GHz frequency).
5.2 The Video page
Note:
The first time you click on one of the Video, Network or System pages, you will be asked for a
password.
Username: admin
Password: this is set when the device is activated.

gop size
The Group of Pictures is the number of consecutive frames that make up a unit in video encoding.
Every GoP starts with an intra-frame, so no data from previous GoPs is required to decode frames
in a particular GoP. All data is needed from a single GoP to successfully decode all frames in it.
Increasing the gop-size means better quality on the same bandwidth. It also means that a lost
packet will affect the video for a longer time.
Note: it is not recommended that you change the default value unless you are
experienced in these matters.
Bitrate
Allows you to change the Bitrate.
This is the bitrate of the H.264 encoded video stream. On the Web Interface it is measured in
kbps (kilobits per second).Thus, this is the approximate size (kilobits) of each second of the video.
Increasing the bitrate increases quality but it does not scale linearly. Higher bitrate also means a
higher bandwidth requirement. If a still image get blocky or blurry, using a higher bitrate can also
help.
In a noisy WiFi environment, frames can be dropped in spite of using the FEC. In such a situation,
using a lower bitrate can reduce the number of dropped frames.
Note: it is not recommended that you change the default value unless you are
experienced in these matters.
Input colorspace
The input device connected to crowdbeamer operates within a specific "colorspace". By default
crowdbeamer detects the colorspace and automatically adjusts for it. In some cases however
crowdbeamer is unable to determine the colorspace (which may happen when crowdbeamer is
