Connecting External Devices
Step 1: Connect the cameras
Connect the coaxial cables from the cameras to the VIDEO IN connectors (1 Vp-p, 75 ohm).
Step 2: Connect the monitor
Connect a VGA cable (not supplied) to the VGA interface and/or an HDMI cable (not supplied)
to the HDMI interface. Connect the other end to a monitor (do not use a TV). Simultaneous VGA
and HDMI output is supported.
Step 3: Connect the mouse
Connect the supplied USB mouse to the USB 2.0 interface.
Step 4: Connect the Ethernet cable
Connect the supplied CAT5e Ethernet cable to the network port. Connect the other end to a
router on your network.
Step 5: Connect audio devices (if applicable)
To record audio, connect the audio sources to the AUDIO IN connectors. To play audio, connect
an audio output device (low-impedance headphones, speaker, or amplifier) to the AUDIO OUT
connector (200 mV / 1 kilohm).
Step 6: Connect alarm devices (if applicable)
Connect alarm devices to the alarm in/out interface. If the alarm inputs use external power, the
device must have the same ground as the DVR. See Appendix A, Connecting Alarm
Input/Outputs for additional information.
Step 7: Connect a PTZ camera (if applicable)
To communicate with a PTZ camera, connect it to the RS485 A and B input. It is recommended
to use
shielded twisted pair cable with the shielded layer used to connect to the ground
. The
ground should be the same as for the DVR and the voltage between the A and B lines should
be less than 5 V.
Step 8: Connect the power cable
Connect the supplied 12 V DC power adapter to the power input. Use of an uninterruptible
power supply (UPS) is strongly recommended.
