I want to perform a web meeting with a customer in the finance business. Network security is important. The installation of a downloaded executable files (".exe") would not be feasible. May I use spreed with my customers?
Yes, you can user spreed without any limitation for web meetings. With spreed you are safe. Holding a spreed meeting does not require software installation and no execution of program files (.exe) at all. spreed is entirely web-based. The only requirement on the participant side is access to the Internet and an Internet browser.
May I share my screen or my desktop with other participants? (Screen/Desktop Sharing)?
With spreed you can easily share your desktop or certain application windows with other participants in the meeting. The maximum number of participants for screen sharing is limited only by the size of your conference room. Conferences starting from 3 (Meet Three for Free, free of charge) up to several 1.000 participants can be held. The participants of the spreed meeting do not need to download, install or start a software application. spreed is footprint-free!
May I use spreed for maintenance- or training-tasks? Is it possible to control a computer from remote?
With spreed you can directly remote access the participant’s desktop. Before remote control can be established, the participant needs to acknowledge remote control of his desktop. Unauthorized remote access thereby is not possible.
Does spreed need special firewall configuration?
A specific firewall configuration is usually not required. In individual cases restrictive firewall- or proxy settings can intercept spreed audio- and video-transmission. So-called "active" or "stateful" firewalls are able to analyze the data traffic and could disconnect the spreed real-time communication. Please contact your system administrator if you are unable to participate in spreed meetings. In cases where the spreed connection is dropped after a few seconds or minutes, the active firewall interrupts the communication flow because of the internet bandwidth being used. Technical background: spreed uses the Real-Time Messaging Protocol (RTMP), for audio and video communication. spreed usually communicates utilizing RTMP over TCP port 1935. When the connection is being dropped because of firewall restrictions, spreed tries to establish a RTMP-Connection via TCP port 80 (the default HTTP-Port) and TCP port 443 (default HTTP/S port). If both ports fail as well, the server will use the standard HTTP protocol for real-time communication. With this technique, about 99.3% of all users can use spreed for real-time communication on their desktops. Nonetheless, in restrictive environments firewalls can analyse the Internet traffic and disconnect if the data-flow exceeds a bandwidth limitation. Please contact your system administrator in this case.
How much Internet bandwidth is required for spreed web conferencing (VoIP, video and presentation)?
The required Internet bandwidth depends on the type of conference. For audio communication (VoIP) a minimum bandwidth of approx. 20kBit/s times the number of speakers is needed. For video and audio an upstream bandwidth between 50 and 120 kBit/s (depending on quality) and 50-120 kBit/s times the [number of conference participants – 1) downstream bandwidth is required. Example: for a spreed conference with 5 participants where each participant transmits both audio and video, each participant requires 50-120 kBit/s connection speed to the server (upstream bandwidth) and 200-480kBit/s downstream bandwidth. Screen or desktop sharing requires about 50 to 300 kBit/s bandwidth depending on the level of detail.
VoIP Audio Quality: Audio is disorted or delayed.
spreed meetings can be held on any location worldwide. When holding a meeting where the distances of the participants are greater then approx. 8,000 Kilometers or 5,000 miles you may experience an audio delay or latency. The latency which you might experience is caused by the time the data packets need to travel between the remote locations. In case the distances between the participants is less greater then approx. 8,000 Kilometers or 5,000 miles and an audio delay still occurs, the IT environment is probably the source of a increased audio latency.
Problems are usually related to the following:
To verify where potential problems are located, please check your Internet environment by using the online connection check in “My spreed” and in the help menu on
- lack of usable Internet bandwidth
- slow firewalls
- slow HTTP proxy servers in combination with firewalls
http://spreed.com/help/check/
If the connection check reports a problem, and either you or your IT department do not know how to interpret the report or resolve issues arising from the report, simply send a copy to spreed technical support for further assistance. spreed fully complies with corporate security rules and does not attempt to overcome IT security firewalls rules or proxies like some other web meeting products do. Therefore, depending on the IT environment, this may cause spreed video and audio to be delayed. Please contact you system administrator. In most cases latencies can be greatly reduced by enabling your firewall to let spreed communicate more efficiently.
Can spreed be used for discussion and analysis of medical image data? A perfect high-resolution image quality is essential for the application.
spreed offers a special application sharing mode for the discussion of medical images. The image data is compressed lossless therefore and will be displayed color-corrected. The maximum resolution is 256M pixel (16284 X 16284) with a color depth of 30 bit (3 x 10 bit).
Remote control of a PC desktop?
With spreed, you can get control a participants desktop. Just acquire remote control on your spreed desktop for the participant's PC. A window will pop up asking your participant if he/she will gain remote control to the desktop. The spreed desktop application need to be started to share the desktop or to remote control a desktop.
Which operating systems are supported?
spreed is entirely browser-based. The only requirement is a recent browser with Adobe Flash Player installed. The Flash player Version 7 or higher comes with almost all browsers. Flash is installed on more than 600 million PC’s. spreed works with most operating systems including Windows, Linux and Mac OS X.
