2.4 On/Off setting
On/Off “Ctrl” setting is only used if wiring for ignition power. ACC Delay can set how long the
DVR will run after the ignition of the truck is shut off. (must be set in 5 minute intervals). Timing
on/ off can be used to set the DVR to run when the ignition is off (start will be the time the
DVR will power on at the time you set and the duration can be used to set how long after
powering up the DVR will run.
The On/Off “Volt” setting is for setting the voltage to shut down and start the device.
When the vehicle’s battery voltage is lower than the Shutdown Voltage, the device will shut
down automatically to avoid excessive battery drain. When the voltage is higher than the
shutdown voltage (Recommended shutdown voltage is 11.5V) the DVR will power back on.

3.1 Main Stream
This interface shows the current Main Stream setting and the corresponding storage size; you
can click any line to set up the corresponding parameters (AV5-8 are available on TH4000 only).
In order to change the resolution of the recordings, change the Bitrate from “Fix” to “Variable”,
then you will be able to change the quality setting. Keep in mind that higher resolutions will
use your storage space more quickly than lower resolution settings.
3.2 Recording storage
for the device to record, either Main or Sub will have to be checked. The system can record
both the Main and Sub stream simultaneously (to prevent recording loss due to Hard Drive
failure). We recommend setting HDD to Main and setting SD to Sub. Make sure to check the
overwrite box to ensure the hard drive/ SD card will overwrite the oldest videos when full.
