Hardware setup
This chapter contains detailed information about the hardware installation and connection of
external equipment to the unit. The connector types and their pin signals are described. Most
of the connectors are located at the rear panel of the unit. For convenience, one USB port is
located on the front of the unit to connect a mouse or memory device.
All the input/output ports are Safety Extra Low Voltage (SELV) circuits. SELV circuits should
only be connected to other SELV circuits.

Camera connections
Connect cameras to the
VIDEO IN
connectors on the back of the unit using 75 ohm video
coaxial cables with BNC connectors. Optionally, this signal can be looped through to other
equipment via the corresponding
VIDEO OUT
connector. The camera input connectors are
auto-terminating. There is no need to add a terminator to the output connector if no
additional equipment is connected.
If the camera signal is looped through to additional equipment, make sure that the end of the
video connection is terminated with 75 ohm termination.
The DVR 600 Series automatically configures itself as a PAL or NTSC unit. The unit determines
the TV standard by detecting the signal format of the VIDEO IN 1 during startup. The unit can
also be manually set to PAL or NTSC in the
Camera menu
under
Video format
.
