6.2.2  Testing the Playback Function 
1.  Once the micro SD card is detected by the system, the button    (inactive) will 
turn to    (active).   
2.  To test the Playback function (this is not required), set up a “Manual Trigger” Recording Event 
by clicking Settings > Event > Event Settings.   
3.  Click the “Add” button on the middle right side of the page to open an “Add Event” box. 
4.  Give the event a name, like “Test 1”. 
5.  In the “Event Triggered by” field, click on Manual Trigger. 
6.  Below this, check “Enable This Event”, “Enable Post-trigger Buffer”, and “Record to SD Card”. 
7.  To save your settings, click OK, or close the box by clicking on the red x icon at top right of the 
box (in which case you will be asked if you want to save the data, click OK if asked). The box 
will close and the new event will be listed in the list area of the Event Settings page. 
8.  Look at the “Post-trigger Buffer” at the bottom to make sure the buffer time is set to 10 
seconds. 
9.  Click “Apply” to make sure all settings are saved. 
10.  Click the Live button to go back to the Live page.   
11.  Get ready to click the Trigger Event button at the bottom of the page. Before you do, see if you 
can find something in the view screen that will give you a visual time marker. For instance, if 
you can get your hand in front of the camera’s lens, get ready to count down on your fingers. 
12.  Click the Trigger Event button and slowly count down on your fingers in front of the lens (if you 
are able to do so – if not, try to find visual cues on the view screen that will help you to mark 
the moment you pushed the trigger). The recording period will be as long as the buffer time 
you selected – the default period is 10 seconds.   
13.  Click the Playback button to open the Playback page. 
14.  There are different ways to search for recording files on the camera’s micro SD card (i.e. the 
Playback memory). For a recent recording like your test event, simply click the “Search” button 
under the “Search by File” header. 
15.  If the micro SD card is active and formatted correctly, the recording folder’s name (the 
recording day’s date) will appear in the Filename box at the bottom. Click on this folder to 
open it. If there are sub-folders, click on the bottom one (the most recent would be at the 
bottom) until you can click on a file that cannot open to another sub-level and shows data in 
the File Information box to the right. This would be the file of the most recent recording event. 
16.  To play this file, click the Play button below the video box. The test footage you have recorded 
should start playing. Play time should be 10 seconds if you left the Post-trigger Buffer as 10 
seconds.
