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 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 7: 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.
