External Record Indicator / Event Mark Button Harness
Figure 8: External Record Indicator/Event Mark Button Harness Connection
The optional external record indicator / event mark button harnesses (Panic Button) are
available with two different types of switches, OEM, and aftermarket. The OEM switch is
rectangular and fits into a standard size dashboard knockout. The aftermarket switch is
round, for easier installation in vehicles without spare switch knockouts. Both styles of
switches plug into the same port on the back of the DVR.
