Installation
Required Tools and Materials
• Small slotted screwdriver with 5/64” or 2 mm blade width
— for connecting power when not using Power over
Ethernet.
Package Contents
Ensure the package contains the following:
• Clearpix H.264 Video Encoder
• Terminal Block
Installation Steps
Complete the following procedures to install the encoder.
1. Mounting the Encoder on page 3
2. Connecting Cables on page 4
3. Assigning an IP Address on page 5
4. Accessing the Live Video Stream on page 6
Mounting the Encoder
The encoder can be mounted in a 19” rack by attaching it to the ENC-
BRK1U encoder bracket that can be purchased separately. The
bracket takes up only 1U of rack space and can hold 3 encoders.
Figure: ENC-BRK1U rack mountable bracket with 3 encoders.

4
The encoder can be attached to the bracket by lining up the four holes
on the bottom of the encoder with the hole pattern on the bracket and
screwing them together with the screws provided with the bracket.
Connecting Cables
Refer to the diagrams in the Overview section for the location of the
different connectors.
To connect the cables required for proper operation, complete the
following:
1. If there are external input or output devices that need to be
connected to the encoder (for example: door contacts,
relays, etc), connect the devices to the encoder I/O
Terminals.
For more information, see Connecting to External Devices.
2. If external microphones or speakers need to be connected
to the encoder, connect the devices to the encoder’s audio
connectors. For more information, see Connecting
Microphones and Speakers.
3. Connect the Ethernet Port (RJ45 connector) to a network
using an Ethernet network cable. The Link LED will turn on
once a network link has been established.
4. Connect power using one of the following methods:
Warning —
• If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of
the rack environment may be greater than room
ambient. Ensure that the ambient temperature
inside the rack does not exceed the maximum
operating temperature of the encoder.
• Ensure that sufficient airflow is provided in the
rack environment such that safe operation of the
equipment is not compromised.
• Mounting of the equipment in the rack should be
such that a hazardous condition is not created
due to uneven mechanical loading.

5
• Power over Ethernet (PoE) Class 3 — If PoE is
available, the encoder is automatically detected
when the network cable is connected.
• External Power — Connect an external 12 VDC or
24 VAC power source to the power connector block.
For more information, see Connecting Power.
5. Connect analog video cameras to the encoder. Use the
coax/BNC connector video inputs on the front of the
encoder.
The encoder supports 4 video inputs and is initially
configured for a composite video input with 75 ohm
termination. The video standard (NTSC/PAL) is
automatically detected. The video input status LEDs will
turn on if the encoder locks to the video signal. If the video
source is connected in parallel with other equipment, the
input termination should be turned off, this can be done
through the encoder web interface.
6. Check that the Connection Status LED indicates the
correct state.
For more information, see LED Indicators.
Assigning an IP Address
The encoder automatically obtains an IP address by default. Once
connected to a network, it attempts to locate and obtain an IP address
from a DHCP server. If this fails, Zero Configuration Networking
(Zeroconf) is used to choose an IP address. When the IP address is
set using Zeroconf, the IP address is in the 169.254.0.0/16 subnet.
The IP address settings can be changed using one of the following
methods:
• (Recommended) Clearpix Camera Installation Tool
software application.
• Encoder's web browser interface:
http://<encoder IP address>/

6
• ARP/Ping method. For more information, see Setting the
IP Address through the ARP/Ping Method.
• Network Video Management software application (for
example, Clearpix Video Management).
NOTE: The default encoder username is admin and the default
password is admin.
Accessing the Live Video Stream
Live video stream can be viewed using one of the following methods:
• (Recommended) Clearpix Camera Installation Tool
software application.
• Encoder's web browser interface:
http://<encoder IP address>/.
• Network Video Management software application (for
example, Clearpix Video Management).
NOTE: The default encoder username is admin and the default
password is admin.

Cable Connections
Connecting Power
NOTE: Do not perform this procedure if Power over Ethernet (POE) is
used.
If PoE is not available, the encoder needs to be powered through the
removable power connector block. Refer to the diagrams in this guide
for the location of the power connector block.
The device can be powered from 12 VDC or 24 VAC. The power
consumption information is listed in the product specifications.
To connect power to the power connector block, complete the
following steps:
1. Remove the power connector block from the device.
2. Remove the insulation from ¼” (6 mm) of the power wires.
Do not nick or damage the wires.
3. Insert the two power wires into the two terminals on the
power connector block. The connection can be made with
either polarity.
Use a small slotted (5/64” or 2 mm blade width)
screwdriver to loosen and tighten the terminals.
4. Attach the power connector block back into the receptacle
on the device.
Warning — This product is intended to be supplied by a UL
Listed Power Unit marked “Class 2” or “LPS” or “Limited
Power Source” with output rated 12 VDC or 24 VAC, 8 W
min. or PoE rated 48 VDC, 8 W min.
