DH4 Basic Configuration
Configuring Signals
The DVR supports 10 independent signals. The first five are dedicated input wire (signal harness) connections: LT (left turn
signal), STP (stop), BRK (brake), WRN (warning lights), and RT (right turn signal).
The last five can be set for other functions, such as an excessive speed event or when the installed G-sensor exceeds a
threshold.
Quality
Leave channel quality at the default setting unless you have special
requirements
.
Setting 1 is the lowest quality, and 4 is the highest. Increased quality
involves greater storage requirements. The DVR uses compression
technology to extend the amount of video (recording time) that can be
stored.

Resolution
Leave channel resolution at the default setting unless you have
special requirements
.
This sets the recording resolution (in pixels). Higher resolution
reduces the amount of video (recording time) that can be stored.
