2

MP2 Viewer searches the file for frames

that match your specified date and time,

and displays the search results.

b Checking Video Files for Any

Tampering

You can appraise whether or not video or date

and time information of stored files has been

tampered with.

1

Enable the tamper detection feature.

Before you open the video file and

display the [Play List] window, select the

[Tamper Det.] check box.

The tamper detection feature works on

all the image files loaded into the Play

List.

The slide bar, at both ends,

indicates the start and end dates/

times of the video file. You have to

specify the search criteria within

this range.

You can use the search feature only

when you are in stop, pause, or normal

playback mode. This feature does not

support other playback modes

(fast-forward, fast-reverse, and

slow-play).

How MP2 Viewer displays the search

result differs depending on the mode

from which the search was initiated.

• Stop or pause:

Displays the frame that matches the

specified date and time as a still

image.

• Normal playback:

Moves the playback to the frame that

matches the specified date and time,

and continues the playback from

there.

Tampering of date and time information

can only be detected when the DVR

from which video data was downloaded

is DSR-M810(P)/DSR-M814(P) and the

firmware version is 2.30-00 or higher.
