When using cameras and power supply units
that superimpose DC voltage on the video
coaxial cable, pay close attention to the coaxial
cable wiring. If the camera cable on which DC
voltage is superimposed is connected to the
NSR, malfunctions may occur.
• To perform pan, tilt, and zoom, control
numbers must be configured. Be sure that
the numbers do not overlap when
multiple analog cameras are connected.
For details on configuring control
numbers, refer to the operating
instructions for the analog camera.
