The relay application is installed and run as a Windows Service. This means that you do not need to log into Windows for the relay application to run. Because the relay is a Windows Service we have made it so that access to the relay settings is done via your web browser, allowing you to remotely login from any location.

The relay application is what makes the whole system work. If the relay is not running then the viewer and transmitter applications cannot be used. The relay application stores all the user accounts used for accessing the system, its job therefore is to handle all login and information request from both the viewer application and transmitter application.

All communication and video between the three applications is done via one TCP/IP port, which is set to the port your choose. The relay settings pages are accessed via HTTP through your web browser on a port set by you, though the default port is 88.

All communication on the TCP/IP port is 128bit encrypted using the encryption key you set. This level of encryption ensures that your system operates and remains secure.

From the relay settings pages you can control and configure the entire system. You can see how many viewers and transmitters are connected and who is using them. You can create and control user accounts for the viewer application and set their privileges for what they can see and do.

The relay application is also responsible for saving/archiving all video streams it receives from the transmitter applications. The archive directory is set by default to the install directory and this is where all the streams will be saved. The video format is a securely encrypted video format, designed to keep you video files safe and tamper proof. To export the archived streams into a standard format you can use the viewer application.

To make it easier for administrators to install the viewer and transmitter applications over network workstations, you can download both installation files from the relay settings pages so that you do not need to physically use the installation CD for every workstation.

Upgrade License
The SurvayaCam system uses licenses to control the number of transmitters and viewer that can connect depend on your number of licenses. From here you can upgrade your license with your new license key.

System Settings
You can control the communication on the relay by setting which TCP and HTTP ports are going to be used to handle the incoming and outgoing traffic. From here you can also set the encryption key to be used for the secure 128bit encrypted communication.

Archive Settings
Every video stream that is sent to the relay from a transmitter is automatically archived so that is can be viewed at a later date. These settings allow you so set a maximum file size for a archive file as well as where they are saved.

Video Profiles
Because the transmitters can send video over GPRS, 3G or Wireless LAN connections you can configure video profiles for different transmitters. The transmitter will then download the video size and quality settings stored in the profile and use them for the video stream.

User Accounts
To make sure only users that are authorised can access the system you have to create user accounts for the viewer application. Users have to enter their username and password to use the viewer application and HTTP viewer. Accounts also have privileges so that you can set what features the user can and cannot use.

Transmitter List
If the transmitter PC goes missing you can ban the PC from being able to connect to your system by denying access to the Relay for that transmitter. The unique ID of the transmitter application will be assigned automatically the first time that it connects to the relay. You can also set which video profile the transmitter will use from here.
