qVideo input connectors 1 to 4 (VIDEO IN 1 to 4)
(BNC, 75 Ω, with auto termination)
These connectors accept video input signals from cam-
eras or recorders.
wVideo output connectors 1 to 4 (VIDEO OUT 1 to 4)
(BNC, loop-thru)

plied to VIDEO IN connectors 1 to 4.
eAudio input connector (AUDIO IN)
RCA audio cable is connected to this connector.
rAudio output connector (AUDIO OUT)
This connector (RCA pin jack) supplies audio output
signal. Connect the cables to a speaker equipped with
the audio amplifier.
tConnector terminal
These are the connectors for alarm input, alarm output,
AUX (auxiliary control) output, and time adjust input.
When connecting an external device, first remove
approx. 9 mm - 10 mm of the outer jacket of the cable
and twist the cable core to prevent a short circuit.
• Specification of cable
(wire): AWG #22 - #28,
Single core, twisted
Important:
• Do not connect 2 or more wires directly to a terminal.
When it is necessary to connect 2 or more wires, use a
splitter.
