<p>[TOC]</p>
<h3>I. Problem Phenomenon</h3>
<h4>1, Longer period of video is missing</h4>
<h4>2, Barcode-like video loss</h4>
<p>the following figure for the phenomenon of video loss through the player view, more detailed phenomena, refer to [Video Status Bar Code Analysis](<a href="http://118.195.179.210:9000/web/#/11/327">http://118.195.179.210:9000/web/#/11/327</a> "Video Status Bar Code Analysis") section.</p>

<h3>II. Analysis steps</h3>
<p>The following steps can be followed to troubleshoot the causes of the problem one by one:</p>
<p>1、Check whether the device is on during the time period when the video is lost.
2、Check whether the device is normal in the time period of video loss disk.
3、Check whether the equipment recording parameters are correct.
4、Check whether the equipment in the time period of video loss is in the ACC off delay of the non-recording stage.
5、Check whether the equipment is in the non-recording stage of the timed recording within the time period of video loss.
6、Check whether the state of video loss is in barcode form.
7、Check whether the equipment clock is normal.
8、The use of disk tools to analyze the state of video data.
9、The equipment configuration camera resolution system and whether the camera matches.</p>
<h3>III, Operating instructions</h3>
<h4>1, Check the video loss time period of the boot state</h4>
<p>1.1 <strong>Platform-Record-Search-Date </strong> to check whether the video time period is blank.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=250c2e75195105a731a3bb764dfb6aa5" alt="" /></p>
<p>1.2 <strong>Platform-Manage-Reports</strong> to check whether the blank time period is online, such as blank time period platform online, video blank, there is video loss, such as can not ensure that the log can be provided to the professionals to troubleshoot.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=82099dda8cdb826d0c16360e7a5c433b" alt="" /></p>
<h4>2, Check the disk status of the time period of video loss</h4>
<p>2.1 <strong>Platform-right-click the device-Terminal</strong> to check the status of the video and the existence of the disk.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=ccb10b5b3aab5c4821340312ea429b5d" alt="" /></p>
<p>2.2 <strong>Platform-Manage-Storage Media RPT-Storagy Medium Disk Error</strong>, select Hard Disk Alarm for alarm type and check whether the device has a disk alarm;</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=d0361b0881df85478ee3baf7d2f0d601" alt="" /></p>
<h4>3, Check the device recording parameters settings</h4>
<p>3.1 At the <strong>RECORS SETUP-Storage-Record Mode</strong> page to check if it's Acc.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=429a7e60634fa1edaed4d17148b1eea5" alt="" /></p>
<p>3.2 At the <strong>RECORS SETUP-Stream</strong> page to see if the main stream channel is on.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=2528c466ceeafda7ef7deabc6997b446" alt="" /></p>
<p>3.3 At the <strong>RECORS SETUP-Storage-Disk</strong> page to see whether the disk usage is record.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=8ce6fc76be5391529e8db522159a00b3" alt="" /></p>
<h4>4, Check the ACC status for the time period of video loss</h4>
<p>ACC video is off, and not set / has passed ACC time-lapse video length / time-lapse video channel is not checked, will lead to video loss.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=59707754a65ced0e9d281cbffc3980fa" alt="" /></p>
<h4>5, Check the timed video recording settings for the time period of video loss</h4>
<p>5.1 At the <strong>RECORS SETUP-Storage-Record Mode</strong> page to check if it's Timed Mode.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=d808ceaf1c3c82bcc2a5483e2a3f0973" alt="" /></p>
<p>5.2 Whether the current time is within the timed recording range.</p>
<p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;sign=5c6a77113bbba9ed2a9706f668ca45ee" alt="" /></p>
<h4>6, Check whether the status of lost video is barcode status</h4>
<p>If the video state is judged to be barcode state, then refer to [Video Status Bar Code Analysis](<a href="http://118.195.179.210:9000/web/#/11/327">http://118.195.179.210:9000/web/#/11/327</a> "Video Status Bar Code Analysis") for analysis.</p>
<h4>7, Check the status of the clock</h4>
<p>7.1 Whether the device time has been set for daylight saving time, time zone.
7.2 Whether there is a manual setting of override time.
7.3 If the above is set, to be time back to the current time, because the time at the video end has been overrun, can lead to video loss, need to format the disk, re-video.</p>
<h4>8, Use disk tools to analyze the video data</h4>
<p>If you can get to the disk, you can be on the computer side, use the disk analysis tools provided by our company, the disk data analysis, please refer to [disk tool usage](<a href="http://118.195.179.210:9000/web/#/11/277">http://118.195.179.210:9000/web/#/11/277</a> "disk tool usage") for analysis.</p>
