connectors. (Set impedence to Hi-Z only when the
video loop-through outputs are used.)
> The DVR4C automatically configures itself as a PAL or
NTSC unit by detecting the signal format of the first
connected camera (lowest camera input number).
2. Connect a monitor to the BNC output MON Out.
> Connect the unit to the monitor using 75-ohm video
coaxial cables with BNC connectors.
Optional connections
3. Connect up to four audio inputs via the RCA
connectors.

detectors, smoke detectors and similar devices. You can
configure the alarm inputs as N/O or N/C in the menu
system. The default is N/O.
6. Connect up to four alarm output relays via the
terminal connector.
> Relay 1 responds to an input alarm, Relay 2 responds to a
system failure and the other relays are assigned to the
remote software. Configure the alarm outputs as N/O or
N/C in the menu system.
7. Connect to your network via the Ethernet port.
> The DVR4C is delivered with the DHCP function switched
on, so IP addresses are assigned automatically if the
network server uses DHCP. (Refer to the System
settings/Connectivity/Network setup menu.)
8. Use the RS232 connector to connect to a PSTN line.
> The serial RS232 console port connector is used to
connect a PSTN modem or a text device to the unit. Use a
null-modem cable to connect the serial port of the external
equipment to the unit. The Baud rate can be selected in
the menu system.
