Broadcasting
The Broadcasting helps you share captured video and audio among Internet users or within local area network.
You can perform broadcasting by different ways:
- Stream to Web server - The program sends video and audio to the PY Software web server. Users connect to this web server and watch the camera.
- Remote Access - other Active WebCam programs connect to the server program which captures video and audio from sources. Server uses UDP protocol to push captured images and sound to the viewers computers.
- HTTP Server - the program runs HTTP server on this computer; viewers can connect to this computer by TCP/IP using any internet browser and see web page with camera's live feed.
- FTP Upload - the program uploads captured images to a web server using FTP protocol. Viewers point Internet browsers to your web site and watch uploaded images.
- Copy Captured Images - the program copies captured images to another folder on your computer in order to use them with other software.
To select the Broadcasting type
- Click Broadcast Settings from the Settings menu.
- Select the Broadcasting tab.
- Click to select the appropriate check box.
 Stream to Web Server
The program sends video and audio to the PY Software web server that users can connect to this web server and watch the camera. This method doesn't require that the streaming computer is accessibly from Internet, and, because PY Software web server has broadband connection, this method provides high frame-rate broadcasting to the unlimited auditory.
You have to be subscribed on PY Software web service to use this broadcasting method. Please use the PY Software web services command from the Tools menu to subscribe for this service.
To activate Web Streaming
- Make sure that you already signed up for PY Software account.
- Click Broadcast Settings from the Settings menu.
- Click to select the Stream to Web server check box.
 Remote Access
Remote Access allows having video and audio on remote computer with very high quality and frame rate, but the opposite side is that viewers must use the Active WebCam program to access camera and camera computer must be visible from Internet (unlike the FTP Upload method).
Click to select the Remote Access check box in the Broadcasting tab to enable access to this camera from other computers. Another copy of Active WebCam should be run on remote computer in order to have Remote Access.
Set up the remote access Frame Rate and the UDP Port value. Active WebCam uses the Port value to receive requests from remote computers. The Port must be available for using, it means it's not used in other programs and it's not used by other cameras in Active WebCam.
Click the Check the Port Availability button to make sure the port it's not used by other programs.
If you want to have Remote Access to the camera from outside local network (from Internet), make sure that the port and IP address of your computer are opened in the firewall. See more info how to configure your network router for remote access.
Click the Additional Settings button to configure Remote Access.
The content of remote access is managed by the Enable Video Stream and Enable Audio Stream buttons.
If you want to control number of remote clients, click to select the Limit Viewers check box and enter maximum number of viewers that can be connected to the camera. All over-limited viewers will receive message: "Administrator has limited the number of camera viewers. Please try again later."
Transferred video and Audio data can be encrypted for security reason. Select the encryption type from the Use Encryption to Transfer Data list.
You can restrict access to the camera by user name and password. Click to select the Use Authorization check box and click the Add button to grant access to this camera to a user or group. Only selected users and users belonged to selected groups have access to the camera. Viewers must enter valid name and password in order to connect to the camera.
 FTP Upload Captured Images
Select the FTP Upload method if you want the program to upload captured images to your Web site using FTP protocol. To watch the captured images, you just need to point your Internet browser to your site.
The benefits of FTP use are: you don't need to have a permanent and fast internet connection (such as, Cable Modem, DSL, ISDN, etc.), and it's not necessary to make your computer to be accessible from Internet (security problems). An opposite side of FTP using is the lower frame-rate.
What is FTP?
FTP is an acronym for File Transfer Protocol. As the name implies, FTP is used to transfer files between computers on a network, such as the Internet. In an FTP transfer, your computer acts as a "client" sending a files to a remote host, or "server". Even computers from different manufacturers and running incompatible software can use this FTP process to exchange files over the Internet. To establish a connection to an FTP server, you generally need to provide a user name and a password in addition to the Internet address of the server (for example, hostname.berkeley.edu); someone would need to set up a user account and assign a password for you before you would be able to access the server.
To run FTP Upload
- Click Broadcast Settings from the Settings menu.
- Click to select the FTP Upload check box.
- In the Frame Rate box enter how often you want to capture images. An image will be captured and broadcasted from your computer each time a specified time has passed. To avoid a CPU overload problem, set the Frame Rate equal to your network bandwidth.
