3.10 Setting up the cameras
With the “preview” setting, you can set the camera parameters and motion detection.
3.10.1 Camera Setting

16
●The DVR can be configured to beep when the camera gets lost.
●User can set the parameters of each camera, including Camera Title, Frequency, Flip Mode,
Brightness, Contrast, Hue, Saturation, Audio Volume, etc.
●The Camera Title should be less than 16 characters.
●The flip mode can be Vertical or Horizontal.。
3.10.2 Motion Detection
●User can set motion detection area.
●DVR can be set to use Adaptive Bitrate to get better video quality, can be set to start recording
when motion detected, or can be set to trigger beeper when motion detected.
●User can set the sensitivity of the motion detection. The higher the value is, the more sensitive

17
the DVR will be.
3.11 Record Setting
3.11.1 Setting Record Details
●Each camera can support PAL/25fps or NTSC/30fps recording, the bitrate range from 100Kbps
to 3000Kbps. The recording support adaptive bitrate control to save recording space. The
bitrate can be down to only 50% of the setting value if there is not too much motion in the video.
For example, if the setting is PAL/25p, 1200Kbps, the actual bitrate can be down to 600Kbps if
there is few motion in the video.
●If you use high bitrate for recording on the SD card, please choose fast speed SD card, like Class
10 SD card .
●The file length can be set from one minute to four hours. Due to the limit on FAT32 file system,
each file size cannot be over 2GB. When the file length is too long and bitrate is too high, the file
size could be over 2GB. In this case, the DVR will close the file and create a new file
automatically to avoid this error.
●There are H.264 and H.265 video modes to be set. Theoretically, H265 consumes 50% less
storage space than H.264 under the same picture quality.
●The file size for one hour recording displayed in the menu is for reference only. The actual file
size could be a little different.
●There are 3 types of recording mode: manual, auto and off. The default mode is auto. In this
mode, the DVR will start recording automatically when the DVR is turned on. If it is set to
manual mode, the DVR will not start to record unless user configures it manually. User can use
the mouse to start recording manually. If any camera is set to off, the DVR will not start to
record on this camera.
●You can click the “start” or “stop“ button to start/stop recording on any specific camera.
●You can click the “apply” button to save the setting.

18
●The record file can be encrypted if you check “using encryption”. If the file is encrypted, the
record file can’t be played on any third party playback software. You can only use the playback
software provided by our company. You would also need to enter the password.
3.11.2 Record Schedule
●The record schedule support three different schedules for recording.
●All cameras can apply the same schedule, or use can set different schedule for each camera.
3.12 Power Setting

19
●Ignition Level: ”Ignition Level” is the voltage level when the ignition is turned on. By default, it
is “High”. For some special vehicle, this value should be set to “Low”.
●ACC Power OFF Delay: The DVR can be set to keep on for some time after the ignition is turned
off, and turned off automatically by the set time. This value is in seconds, the default value is 30
seconds. In this case, the DVR will go to standby. In standby mode, the DVR will not be powered
on unless the ignition is turned on again. And even if the ignition is turned on again, the DVR
will still need about one minute to boot up completely and start recording. If the “ACC Power
OFF Delay” is set to 0, the DVR will be always on and not be turned off even if the ignition is
turned off.
●Sleep Delay-ACC Off: This parameter is used to set the timeout when DVR is going to sleep
mode after the ignition is off. In sleep mode, the camera will be turned off, but the DVR is still
working. This is different from the case when using the “ACC Power Off Delay” to let DVR go
into standby mode. In sleep mode, as the DVR is always working, the DVR will power up the
camera and start recording immediately when there is any alarm is triggered. The “Sleep
delay-ACC Off” value usually should be set to a value larger than “ACC Power OFF Delay”,
otherwise the DVR will go to standby mode before going to sleep mode. If “Sleep Delay-ACC Off”
value is set to 0, the DVR will not go to sleep mode.
●Sleep Delay-No Alarm: This parameter is to set the timeout when DVR is going to sleep mode
after last alarm (event) occurred. If this value is set to 0, the DVR will not going to sleep mode
even if there is no alarm.
●Timer Power On/Off: This is to set the DVR to turn on/off at specified time. If both value is set
to “00:00”, this feature is disabled.
●Power On/Off Threshold Voltage: When the voltage connected to the DVR is higher/lower than
the Power On/Off Threshold Voltage, the DVR will turn ON/OFF. When it is set to “0”, the setting
is OFF.
The reason that we have two power-saving modes (the standby mode and the sleep mode) for DVR
is that in some cases the DVR should resume recording immediately from power save mode. In
standby mode, the DVR is turned off and the cameras are also turned off, the power consumption
will be very small. But the DVR needs about 20 seconds to boot up before it can resume recording.
In sleep mode, the DVR is still on but the cameras are turned off. The sleep mode will have more
power consumption than standby mode, but it will have less power consumption than working mode.
A typical use for sleep mode and standby mode is for taxi application. The DVR can set “ACC Power
Off Delay” to 21600 seconds (6 hours), “Sleep Delay-ACC off” to 10800 seconds(3 hours), and
“Sleep Delay-No Alarm” to 10800 seconds(3 hours). We will also connect the taxi meter signal to the
“Sensor 1” (Alarm 1) and the door open signal to “Sensor 2” (Alarm 2). These two sensors will
trigger recording. With this configuration, if the taxi is parking (no ignition) for 3 hours, and there is
no passenger (no meter on or no door open) for 6 hours, the DVR will go to sleep mode. But during
this time, if the taxi is turned on or there is a passenger, the DVR will start recording immediately. If
the taxi is parking (no ignition) for 6 hours and there is no passenger (no meter on or no door open)
for 6 hours, we will think the taxi is not running, the DVR will go to standby mode.

20
3.13 Motor Setting
●License ID: Set the plate number, support characters (case sensitive) and numbers.
●Support to get speed from speedometer, the speed unit can be km/h or mile/h;
●The over-speed value is configurable. The over speed alarm can be used to trigger recording. If
the over speed value is set to 0, the over speed alarm will be disabled.
●“Overspeed OSD”: Set the tile displayed when over speed.
●“Overspeed Buzzer”: Turn on/off buzzer when over speed.
