MPEG decoder installation If no video images are displayed when you click the MPEG-4 link, it may be necessary to install a current MPEG decoder. This software is available for download from DVTel’s website. Establishing the connection The 7700 Series unit must be assigned a valid IP address for your network before it can be operated in the network environment. - Page 15 If the unit is a transmitter, the home page will be the Video Viewer (which shows the live video image, if a camera is connected to the encoder). The Connection page will be displayed as the home page for a receiver. It shows a snapshot from the video source for the transmitter currently connected, and the unit searches the network automatically for available transmitters.

Page 21: Camera Name
Camera name The camera name simplifies identification of the remote camera location, for example in the event of an alarm call. It can be shown in the video image if this feature is enabled and configured (see page 21). Display stamping Various overlays and stamps can be added to the video to provide important supplemental information. -
Page 22: Mpeg-4 Encoder Configuration
MPEG-4 Encoder configuration The 7700 Series transmitter has two MPEG encoders that can be configured separately. This allows for the transmission of two different video streams, which can be used for different applications (e.g. live viewing and recording). There are several pre-programmed profiles, optimized for different application scenarios, available for each MPEG encoder. - Page 23 • low delay (2CIF) for high bandwidth connections, 704 × 288 pixel resolution • low res. (CIF) for moderate bandwidth connections, resolution 352 × 288 pixels • DSL for DSL connections with 500 kbit/s • ISDN (2B) for ISDN connections via two B channels •...

Live video auto-connect: Select On here if an active connection should be established after each reboot, for example following a connection failure or power failure. - Page 27 Motion detector Select On to activate the video sensor. Select sensor field You can select the areas of the image to be monitored by the video sensor. The video frame is subdivided into 396 square cells. Each of these cells can be activated or deactivated individually. If it is necessary to exclude particular regions of the camera field of view from the monitoring process due to continuous movement (a tree moving in the wind, etc.), the relevant cells can be deactivated.

Page 32: Multicast Settings
Multicast settings In addition to a "one on one" connection (unicast) between a transmitter and a receiver, the 7700 Series unit also supports multiple connections. With multicasting, several decoders receive the video signal from an encoder at the same time. There are two methods for multiple connection: multi-unicast and multicast. In multi-unicast mode, the unit's data stream is duplicated and passed on to multiple receivers. -
Page 33: Version Information
Multicast audio port: With MPEG-4, video and audio data is transmitted via separate ports. To transmit MPEG-4 with audio you must assign a dedicated audio port. Note Audio data is only transmitted if the corresponding function on the Audio configuration page is enabled (see page 24). -
