Install the hardware
Mount AXIS P8221
AXIS P8221 is supplied with a mounting kit containing screws and plugs for mounting the device to
a concrete wall:
1. Place AXIS P8221 against the wall and mark the location of the two mounting holes (see
page 4) through which the device will be attached.
2. Remove AXIS P8221 and drill the two mounting holes.
3. Insert the wall plugs into the wall, position AXIS P8221 and attached to the wall using the
screws provided.
The supplied protective pads can be used to avoid scratching the surface on which AXIS P8221 is
placed. Punch out the pads and apply them to the underside of the device.
Connect the cables
Please refer to Unit connectors, on page 13, for wiring information.
1. Optionally connect external input/output devices, e.g. alarm devices.
2. Optionally connect external audio equipment.
3. Optionally connect external equipment to the RS-232/485/422 connector.
4. Connect AXIS P8221 to the network using a shielded network cable.
5. Connect power, using one of the methods listed below:
• PoE (Power over Ethernet). If available, this is automatically detected when the network
cable is connected.
• Connect an external power adapter to the power connector block.
6. Check that the indicator LEDs indicate the correct conditions. See the table on page 17 for
further details.
!IMPORTANT! - The casing of AXIS P8221 is not approved for outdoor use. The device
may only be installed in indoor environments.

Assign an IP address
Most networks today have a DHCP server that automatically assigns IP addresses to connected
devices. If your network does not have a DHCP server AXIS P8221 will use 192.168.0.90 as the
default IP address.
AXIS IP Utility and AXIS Camera Management are recommended methods for setting an IP
address in Windows. These free applications are available on the AXIS Network Video Product CD
supplied with this product, or they can be downloaded from www.axis.com/techsup. Depending on
the number of devices you wish to install, use the method that suits you best.
Notes:
• If assigning the IP address fails, check that there is no firewall blocking the operation.
• For other methods of assigning or discovering the IP address, e.g. in other operating systems, see
page 11.

2. Start AXIS IP Utility.
3. When AXIS P8221 appears in the window, double-click to open its home page.
4. See page 9 for instructions on how to assign the password.
Set the IP address manually (optional)
1. Acquire an unused IP address on the same network segment as your computer.
2. Select AXIS P8221 in the list.
3. Click the button Assign new IP address to selected device and enter the IP address.
4. Click the Assign button and proceed according to instructions.
5. Click the Home Page button to access the device’s web pages.
6. See page 9 for instructions on how to set the password.

Page 8 AXIS P8221 Installation Guide
AXIS Camera Management - multiple devices/large installations
AXIS Camera Management can automatically discover multiple Axis devices, show connection
status, manage firmware upgrades and set IP addresses.
Automatic discovery

ENGLISH
Set the password
To gain access to the device, the password for the default administrator user root must be set. This
is done in the ‘Configure Root Password’ dialog, which is displayed when AXIS P8221 is accessed
for the first time.
To prevent network eavesdropping when setting the root password, this can be done via an
encrypted HTTPS connection, which requires an HTTPS certificate.
Note: HTTPS (Hypertext Transfer Protocol over SSL) is a protocol used to encrypt the traffic between web
browsers and servers. The HTTPS certificate controls the encrypted exchange of information.
To set the password via a standard HTTP connection, enter it directly in the first dialog shown
below.
To set the password via an encrypted HTTPS connection, follow these steps:
1. Click the Create self-signed certificate button.
2. Provide the requested information and click OK. The certificate is created and the password can
now be set securely. All traffic to and from the device is encrypted from this point on.
3. Enter a password and then re-enter it to confirm the spelling. Click OK. The password has now
been configured.
4. To log in, enter the user name “root” in the dialog as requested.
Note: The default administrator user name root cannot be deleted.
5. Enter the password as set above, and click OK. If the password is lost, the device must be reset
to the factory default settings. See page 18.
To configure the password directly
via an unencrypted connection, enter
the password here.
To create an HTTPS connection, start
by clicking this button.

Unit connectors
RS-232/485/422 connector - 5-pin terminal block for the RS-232/485/422 serial interface used
to control auxiliary equipment. The port can be used in the following modes:
• 2TX/2RX RS-232 interface (RD, TD, RTS, CTS)
• Bidirectional RS-485 half-duplex port for data transmission using
two wires, one combined RX/TX pair
• Bidirectional RS-485 full-duplex port for data transmission using
four wires, one RX pair and one TX pair
• Unidirectional RS-422 port for transmitting and receiving data
using two wires, RX- or TX pair
• Bidirectional RS-422 full-duplex port for data transmission
(point-to-point) using four wires, one RX pair and one TX pair
Note: When using a long cable and high communication speeds it is recommended to insert a 120 ohm
termination resistor between the RS-485 wires at both ends of the cable.
Audio 1:
Audio in (pink) –3.5 mm input for a mono microphone, or a line-in mono signal (left channel is
used from a stereo signal).
Audio out (green) –3.5 mm output for audio (line level) that can be connected to a public address
(PA) system or an active speaker with a built-in amplifier. A pair of headphones can also be
attached. A stereo connector must be used for the audio out.

I/O terminal connectors A and B - Used in applications for e.g. event triggering and alarm
notifications. In addition to an auxiliary power and a GND pin, each I/O terminal connector has 4
pins that can be configured as either input or output. These pins provide the interface to:
• Digital output – For connecting external devices such as
relays and LEDs. Connected devices can be activated by
VAPIX® Application Programming Interface (API), by output
buttons on the Live View page or by an Event Type. The
output will show as active (shown under Ports & Devices >
I/O Ports) if the alarm device is activated.
• Digital input – An alarm input for connecting devices that
can toggle between an open and closed circuit, for example: PIRs, door/window contacts,
glass break detectors, etc. When a signal is received the state changes and the input
becomes active (shown under Ports & Devices > I/O Ports, and, if enabled, on the Live View
page).

Digital output – Uses an open-drain NFET transis-
tor with the source connected to GND. If used with
an external relay, a diode must be connected in
parallel with the load, for protection against volt-
age transients.

Resetting to the factory default settings
This will reset all parameters, including the IP address, to the factory default settings:
1. Disconnect the power from AXIS P8221, or if PoE is used disconnect the network cable.
2. Press and hold the Control button (see page 4) and reconnect power or the network cable if PoE
is used.
3. Keep the Control button pressed until the Status indicator displays amber (this may take up to
15 seconds).
4. Release the Control button. When the Status indicator displays green (which can take up to 1
minute) the process is complete and the device has been reset.
5. Re-assign the IP address, using one of the methods described in this document.
It is also possible to reset parameters to the original factory default settings via the web interface.
For more information, please see the online help or the User’s Manual.
Access from the Internet
Once installed, your AXIS P8221 is accessible on your local network (LAN). To access AXIS P8221
from the Internet, network routers must be configured to allow incoming traffic, which is usually
done on a specific port
• HTTP port (default port 80) for viewing and configuration
• RTSP port (default port 554) for playing audio streams
Please refer to the documentation for your router for further instructions. For more information on
this and other topics, visit Axis Support web at www.axis.com/techsup
