ALARM PRE-REC TIME
(
1-60
)
MIN:
Pre-record time setting is from 1 to 60 minutes. For example: If the setting for
pre-record is 30min, when alarm is triggered at 10:30, then the record file
starting from 10:00 to 10:30 will be packed as one alarm file.
HDD/SD OVERWRITE:
There are 2 options for the INTERNALand EXTERNAL. INTERNAL is used for the internal
mirror recording SD card. If the MDVR connects external fireproof box for mirror recording
then the user should select EXTERNAL option. Mirror recording means that the hard disk
and SD card can record at the same time with same frame, same resolution, same
image quality. The main purpose for mirror recording is: when the hard disk is broken (like
accident happens) the user can still get the video files in the last minute from the SD card.
X3II MDVR can provide 2 kinds of mirror recording internal and external. Internal means
that we have the SD card slot inside of MDVR device and the user just need to insert the
SD card in the slot on the MDVR device and ENABLE the switch for mirror recording on
the MDVR GUI menu. External symbolize that the user need to buy the fireproof box (SD
card inside) in case the vehicle is on fire. This fireproof box is specially
design for the vehicle accident (like fire) and the maximum temperature can be 500
Celsus degree (can last 15 minutes)
