Trigger for recording not working

[scandal929]

Hopefully someone can help me, I have AHP
and IWitness.  Camera is hooked to PC which
can view and record if done manually to hard
drive.  As far as I can tell Macro is set
properly.  Only thing not working is having
the recording activated by the motion
sensor.  Flood lights work view show up on
PC but never records.  Any help would be
appreciated.  Thanks in advance!!!
