Image resolution
Snapshots can be called up and displayed at different resolutions by entering URL parameters in the address
field of the Web browser. Just append the corresponding parameter to the snap.jpg command:
• snap.jpg?JpegSize=S for 176 × 144 pixels
• snap.jpg?JpegSize=M for 352 × 288 pixels
• snap.jpg?JpegSize=XL for 704 × 576 pixels
Without the extra parameter, the default image size is 352 × 288 pixels.
– Type the IP address of the 7700 Series unit, followed by /snap.jpg into the Internet address field as URL
(e.g. http://192.168.0.12/snap.jpg).
– Press the Return key or Enter key. A single frame image will be displayed in a new window.
– Right-click the image and select Save Picture As... from the context menu.
– Save the snapshot in the desired format, giving it a new name.
Recording video sequences
You can manually save segments of the current video sequence displayed in the Video Viewer to your hard
drive. The video sequences will be stored in MPEG format.
– Click the MPEG Recording icon to start recording a sequence. The storage location depends on the
configuration of the 7700 Series unit (see page 34).
Recording begins immediately. The red dot on the MPEG Recording icon flashes while the recording is in
progress.
– Click the icon once more to stop the recording.
Note
