The viewer application is used to watch the incoming live video streams that are being sent from the transmitter applications. The streams are relayed by the relay application from the transmitter to the viewer applications.

To use the viewer application the user must first login to the system by entering their username and password. Once logged in the user will have access to the features that their account privileges allow. User accounts are set and stored on the relay application.

The first screen the user will see after login is the live stream screen, where a recent thumbnail image will be displayed for each of the live streams being sent by the transmitters. To watch these streams in real time the user simply clicks on the play option to show the player window for that stream.

The player window allows the user to see the incoming video stream and rewind through the streams history. The user can use the video, zoom, and drawing options to enhance the video they are watch, without effecting the original copy. Depending on the users privileges they can also control and configure the transmitter from the player window and export the video stream into an external video file.

Exported archives can be verified at anytime by using the Video Verifier. The verifier is an optional install, but if you have installed it you can right click on any exported archive file and click the "Verify with SurvayaCam" option in the menu. This will instruct the verifier to scan the file and check whether it has been tampered with. If the file has been modified you will be informed otherwise you will be shown the encrypted SurvayaCam information that is embedded into the file.

The user can also use the search archive option (depending on privileges) on the viewer to find archived video streams between specific dates or from a specific transmitter. Once the search has been performed the archived stream that meet the search criteria will be displayed in the list. From the list the user can choose to play one or all of the returned streams.

To help keep track of important archived streams the user can bookmark the returned streams (depending on privileges) so that when they go to their bookmarked streams, they are already listed without the user having to perform another search.

As well as the viewer application you can also watch live streams on a PDA or mobile phone via the devices web browser. The address is the IP address of the relay application, eg. http://127.0.0.1, as long as the port on the relay settings is still set to 80.

If you go to the address in the devices web browser you will still have to login, but once logged in you will only be able to watch live stream and only one at a time. This HTTP viewer provides a truly mobile surveillance system.

User Login
To make sure your system is only accessed by authorised users, the user must first login using their accounts details to gain access viewer features. Once logged in the account privileges will determine which features the user has access to.

Live Streams
You can watch all incoming live video stream from the connected transmitters simply clicking the play option on the live stream thumbnail. This will create a player window in which you can watch the video stream.

Archive Streams
Every stream that is send by the transmitters is archived by the relay. A user can run search queries to find specific video streams. From the returned results you select to watch one or more of the video streams.

Bookmark Streams
Once a user has found the archive stream they were searching for they can bookmark the stream so they can access it again in future without performing another search. Bookmark streams are stored separately under each user account.

Stream Playback Options
When viewing a video stream the user can control the video playback. They can rewind, fast forward, pause, stop, play and change the playback speed of the video.

Stream Timeline Scanning
Every frame of video in a stream is time stamped and dated as it is received by the relay. A user can scan forwards or backwards through the timeline to find a specific event or just to review past events.

Video Options
If video from a transmitter is too dark or reduced in quality because of its connection speed, the video options allow dynamic adjustments of the contrast, brightness, sharpness and the option to smooth the video as well as invert it.

Drawing Options
The drawing options are for highlighting areas of interest on the video stream for exporting. You can also blur out areas of video as well as zoom in on a selected area of the video frame.

Zoom Options
If you need to get a closer look at something on the video, you can use the zoom options to zoom in and out of the video. Once zoomed in you can pan around the video using your right mouse button.

Export Options
Using the export options you can save video stream as a video file, still image frame or print a frame of video. You can also set <A & B> markers to set the begin (A) and the end (B) points in the video stream you want to export.

Audio Messages
Audio messages are used to send an audio information to the transmitter operator. Though the message is sent in text format, it is converted to audio by the transmitter application and played so that the user can hear the message.

Transmitter Control
You can control the connected transmitters by using the configure options. This feature allows the user to remotely administration and change the setup of the transmitters.
