POWER
Your NVR will have either a pair of small ports (top) or a single, more
conventional power port (below). On systems with the two ports, one
is for the NVR’s power supply while the second is for the power supply
that powers the POE (Power Over Ethernet) ports. The two power
supplies can only be plugged into the correct port. Do not attempt to
force a power supply plug into the wrong port.
NVRs with a single power port have an internal power supply that also
provides power to the POE ports.
NETWORK PORT
Use this single Ethernet port to connect your NVR to your network
router.
Do not connect a camera to this port.
POWER OVER ETHERNET (POE) CAMERA PORT
These ports will be in groups of four or more. Plug your camera’s
Ethernet cable into one of these ports.
HDMI
Use the included HDMI cable to connect to a high-definition video
display.
USB
Depending on the model of your NVR, these ports may be located on
both the front and back panels. Connect your USB mouse to one of
the ports on the back panel, leaving the other port available for use in
backing up files.
VGA
For connecting your NVR to a VGA computer monitor. VGA cable not
included.
VIDEO OUT (BNC)
Also used for connecting a standard television as a video display.
Requires a BNC-to-RCA adapter or cable.
Depending on your model, your NVR may have one or more of these ports as well:
RS232
This port is for factory maintenance only.
AUDIO
Standard RCA-type connectors. Audio In ports are for connecting
microphones which have been located near a camera to capture audio.
The Audio Out port is to connect to a speaker. The color of these ports
may vary.
VIDEO OUT (RCA)
Connect to a standard television as a video display using an RCA cable
(not included).
ALARM BLOCK
This serves as a connection point for one or more external alarms or
sensors. Full details are given in the Alarms section of this manual.
The size of the block will vary.
ESATA
Models with this port can back up files to an external hard drive.
