Chapter 5 — RAS Search

5.1 Description

The RAS Search is remote search software, which searches for recorded images on the remote

DVR and plays back the found images. In addition to time-lapse search, event search and

playback functions, the RAS Search also provides additional functions including image zoom,

image interpolation, file (image) save and file (image) print. Features of the RAS Search

program are as follows:

• Time-lapse and event search

• Recording status table

• Zoom

• Various image enhancement

• Current image saving

• Current image printing

The search function of the RAS Search is divided into two modes of operation: time-lapse

mode and event mode. Time-lapse search is a process that the system searches for recorded

data by time and then plays back the found images. Event search is a process that the system

searches for event log entries using specific conditions and plays back the images associated

with those event entries. These two modes are different in screen configuration and search

method. The default setting of the RAS Search is the time-lapse search mode. The last search

mode used is automatically selected when the RAS search function is executed again.

To search for and play back recorded images, the user should first select a remote site to

access. Click the Remote Sites button to display the list registered in RAS Admin, and then

click the

(Connect) button to connect to the selected site. Release (select a second time)

the

button to disconnect from the current connection.

5.2 Time-Lapse Search

In the time-lapse mode, the system searches for recorded images by time and plays back the

found images. Selecting a date from the calendar initiates time-lapse search. The dates for

which recording is available are displayed in bright white characters. When first entering the

time-lapse search, the newest recorded date will be selected (highlighted in yellow) in the

calendar. Click the

(Reload) button to reload the date information. Recorded information

available from the selected date is shown on the recording status table. The recorded data are

displayed by time (in hour segments). A yellow line indicates the selected time (in hour

segments) that will be played back. Go to a specific hour by clicking the mouse on the desired

hour segment. Video images will be played back starting with the first image captured within

the one-hour segment.
