12. Frequently Asked Questions
Performance
1. What frame rate can you guarantee?
Our target for the first release is 20 frames per second.
2. What is the minimum and maximum supported output resolution for the central screen?
- XGA (1024x768@60Hz)
- WXGA (1280x800@60Hz)
- SXGA (1280x1024@60Hz)
- SXGA+ (1400w1050@60Hz)
- WXGA+ (1440x900@60Hz)
- WSXGA+ (1680x1050@60Hz)
- UXGA (1600x1200@60Hz)
- HD (1920x1080@60Hz)
- WUXGA (1920x1200@60Hz)
3. What is the maximum input/source resolution?
The average laptop resolution of 3 Megapixel can be handled by the system. The theoretical limitation on the input resolution
is higher. However, video performance and image quality will deteriorate for such high resolutions.
4. What is the noise level of the Base Unit?
In normal operating conditions (up to 25°C), the noise level of the alpha Base Unit is 28dBA. Please note that this is not yet the
final specification. Final specifications are measured on the zero units.
5. Does ClickShare support extended desktop?
No, only the primary screen of the laptop is scraped, even if your laptop is in a docking station and connected to a second
monitor with extended desktop.
6. Does ClickShare support dual screen presentation mode in MS PowerPoint?
As extended desktop is not supported, this functionality is also not supported.
WiFi & Security
1. What WiFi security do you have?
- Authentication protocol: WPA2–PSK
- Encryption algorithms: CCMP
This is currently the best security protocol widely available.
2. Can I detect the ClickShare Base Unit when I scan for wireless networks/access points?
That depends on your operating system and the software you use to scan for wireless networks or devices. At most, a network
called “SSID not broadcasted” or “Hidden WLAN” (or something similar) will show up in the list of wireless networks. Because
the SSID (Service Set Identifier) is not visible, it is not possible to connect to it.
3. Can I connect to the Base Unit via my PC Wifi card?
No. You need to know the SSID of the network and security password to be able to connect to it. The SSID (Service Set
Identifier) is not visible for users. To make the SSID visible for users, the configuration pages of the Base Unit can be accessed
(password protected) and the settings can be changed to “Broadcast SSID”.
4. What is the maximum distance between Base Unit and ClickShare Button?
4) The typical maximum distance recommended for WiFi connections depends on the used band and environmental parame-
ters. Typical values are 50m in free air for the 2.4 GHz band and 30m in free air for the 5 GHz band. When installed in e.g.
a false ceiling or inside a cabinet, this distance will be shorter. The maximum distance depends heavily on the physical ma-
terial between ClickShare Button and Base Unit. However, the signal is not “cut off” beyond that distance. Instead, the signal
gradually decreases.
5. What WiFi do you use? Is it 802.1.n or 802.1.g?
ClickShare is compatible with 802.11.n.
6. What about interference with other WiFi devices?
It is very unlikely that WiFi interference will limit the performance of ClickShare or other devices within its immediate proximity.
This is because ClickShare works in both the 2.4 GHz band as well as the 5 GHz band, which leaves you with many options
to choose the channel that is used the least in your environment. Moreover, the system only uses limited bandwidth (typically
1Mbit/s, rarely maximum 30Mbit/s), which makes collision with other clients in the same band unlikely. The person who installs
the system can manually select the most appropriate band to be used by the system.
7. How many WiFi channels are available?
The available channels depends on the geographical region.
8. Do you install anything on my PC?
No. ClickShare is a zero footprint solution. After plugging out the Button no trace is left on your PC.
9. Do you support Bluetooth?
No, Bluetooth cannot support the bandwidth necessary for video.
Compatibility
1. Can ClickShare work with video conferencing?
Yes, if your video conferencing system supports a data channel. In that case you can use the output of the Base Unit as input
for the data port of the Codec.
2. Can you control it via Crestron?
No, Crestron control (RS-232 or API) is currently not foreseen.
