connect IP cameras, you need to connect the DVR to your network. You must use a normal straight-type
network cable and insert it on one side into the NET port of the DVR and on the other into a free port on
your router or switch. The DVR is factory set to automatically configure itself on the network (DHCP).
And | AB RS485–This is the RS485 serial port to which you can connect the control pair to control analog
or AHD motorized cameras. While our latest motorized analog cameras support motion control along
the video cable by selecting UTC command protocol, older motorized analog cameras require these two
additional cables for control. The RS485 BUS is a twisted pair that connects in cascade all the analog
motorized units of your system. You can find more information in the camera manual on how it should
be connected, always respecting the A(+) and B(-) terminals found on the camera. You will then have to
configure the transmission protocol, in the PTZ configuration of the DVR, based on the camera. You need
to select the protocol, usually PelcoD, the speed, usually 1200,
Motorized IP cameras do not require this connection because they are controlled via the network cable.
F | VGA–You can connect a computer monitor that has this type of port to this output. This output
supports the maximum resolution of 1920x1080 FullHD.
G | INPUTS–You can connect alarm contacts to these terminals as explained later H | EXIT–You can
connect the alarm output to these terminals as explained later I | A1..A4–You can connect audio signals
from analog cameras or microphones to these RCA inputs. Remember that these audio inputs are only
active for BNC channels because IP cameras require the microphone to be connected to the camera.
L | HD OUT–This is the HDMI output for the monitor. Almost all TVs and PC monitors have this
connection port. If you connect a TV, to see the images you must remember to select the external HDMI
input you used for the NVR on your TV. This is typically done by pressing the SOURCE button on the
remote control. These DVRs come from the factory with a low output resolution which you can increase
up to 4K to match the maximum resolution of your monitor. This operation is explained better later in
the manual
Remember that the HDMI cable cannot be longer than a few meters. To connect an HDMI monitor
remotely from the NVR you must use an HDMI transmission device.
M | USB–To the USB ports you can connect the mouse included with the DVR and USD memories, such
as USB sticks or hard disks to back up video files. All DVRs also have a front USB port.
N | DC 12V–Connect the included 12VDC power supply here. Be careful not to confuse the DVR/NVR
power supply, which has at least 2A of power, with other smaller ones you have
