Chapter 3: Playback
Basic Playback
1) Search
Results
the browser here shows the search result with tag, description and event time.
Click on the result will open the corresponding media-file and seek to the
position where the event occurred.
2) Channel
Selectors
the channel to search.
3) Search
Panel
video and event searching. Keyword is the tag you inserted manually or defined
in program modules. You can also open the Advance Search dialog to input
arbitrary time range and channel to search.
There are 3 search modes:
a) Simple – condition matches when a tag contains the search keyword.
b) Exact – condition matches when a tag is exactly equal to the search keyword.
c) Wildcards – search tag with wildcards.
i) ‘%’: represent a string of zero or more characters. For example, “213%” searches tag like “213”, “21300” or “213-1345”, etc.
ii) ‘_’: represent any single character. For example, “_ong” searches tag like “zong”, “song”, etc.
iii) ‘\’: represent an escape character. You can use escape characters to tell the search engine to treat wildcard characters and this escape character as regular characters. For example, “100\%” searches tag “100%”, and “abc\\def” searches tag “abc\def”.
One useful wildcards application is
to search number greater than some values. For example , “%$%_,___%” can search
money greater than $999.
