报警录像
<p>说明
MDVR使用裸盘读写技术，数据直接写入block上；
当报警预录和延时的时间过长，导致报警文件跨越两个block的时候，会被分成两个文件；
如果文件片段里面没有包含报警，就会被MDVR标记为Normal录像文件；有报警则标记为ALARM文件；
对功能使用没有影响。</p>
<p>如果不想在报警录像模式下看到Normal类型文件，可以把报警预录，报警延时录像，报警延时全部设置为0.
设置见下文。</p>
<p>If you only want alarm recording files and don't want general recording files, please follow the below steps to set alarm recording on mdvr.</p>
<p>1.Set record mode to ALARM RECORD
Go to MDVR MENU -- RECORD -- GENERAL ,and change record mode to ALARM .
Then mdvr will only record when an alert is triggered.
