AXIS P8221 - Audio Streams Alternative methods of accessing audio QuickTime and Windows Media Player Simplex audio can be accessed via QuickTime and Windows Media Player by using the paths below. QuickTime supports G.711 and AAC audio encoding. • • Windows Media Player. This requires AXIS Media Control to be installed. The paths that can be used are listed below in the order of preference: • Unicast via RTP: axrtpu:///axis-media/media.amp • Unicast via RTSP: axrtsp:///axis-media/media.
AXIS P8221 - Setup Tools Setup Tools AXIS P8221 can be configured by users with administrator or operator rights: • • Administrators have unrestricted access to all settings. Operators have access to Audio, Live View Config and Events. To configure the product, click Setup in the top right-hand corner of the Live View page. Click that explains the setup tools.
AXIS P8221 - Audio Audio Audio equipment AXIS P8221 has two connectors, Audio 1 and Audio 2, for external audio equipment. See table below for examples of supported audio equipment. The Audio 2 terminal connector can power microphones requiring 48 V phantom power and has a built-in amplifier enabling direct connection of passive speakers. The Audio 1 connector can power small electret microphones. Please see Unit connectors, on page 32, for wiring information.
AXIS P8221 - Audio Audio Settings The audio settings are configured under Setup > Audio > Audio Settings. Audio Channels Audio mode - The available audio modes are • Full duplex. Simultaneous two-way audio allowing you to transmit and receive audio (talk and listen) at the same time. • • • Note: There is no echo cancellation; if feedback loops appear, try moving the microphone or the speaker. Half duplex.
AXIS P8221 - Audio Select the desired audio Encoding format, G711 μ-law, G726 or AAC. Select the required Sample rate (number of times per second the sound is sampled). The higher the sample rate, the better the audio quality and the greater the bandwidth required. Changing the Bit rate changes the audio compression level and hence audio quality. A higher bit rate can improve audio quality but requires more bandwidth.
AXIS P8221 - Audio Audio Clips An audio clip is a sound file that can be played when an event occurs or manually from the Live View page. Audio clips can be recorded by a microphone connected to AXIS P8221 or uploaded to the device. Add a new audio clip To add an audio clip, go to Setup > Audio > Audio Clips and click Add... The dialog expands with two choices Record and Upload. Record To record a clip using the microphone: 1. 2. 3. 4. 5. Select the Record radio button. Enter a descriptive Name.
AXIS P8221 - Ports & Devices Ports & Devices I/O Ports AXIS P8221 has eight configurable input and output ports for connection of external devices. • • Output ports - For connecting external devices such as relays and switches. Devices connected to an output port can for example be used to remotely control devices such as lights and doors.
AXIS P8221 - Ports & Devices Output ports Devices connected to output ports can be controlled by output buttons on the Live View page, by events and by the VAPIX® Application Programming Interface.
AXIS P8221 - Live View Config Live View Config Go to Setup > Live View Config > Layout to customize the appearance of the Live View page.

AXIS P8221 - System Options System Options Security Users User access control is enabled by default. An administrator can set up other users, by giving them user names and passwords. It is also possible to allow anonymous viewer login, which means that anybody may access the Live View page, as described below: The user list displays the authorized users and user groups (levels): Viewer Operator Administrator Provides the lowest level of access, which only allows access to the Live View page.
AXIS P8221 - System Options Clients and servers in an IEEE 802.1X network may need to authenticate each other by some means. In Axis implementation this is done with the help of digital certificates provided by a Certification Authority. These are then validated by a third-party entity, such as a RADIUS server, examples of which are Free Radius and Microsoft Internet Authentication Service. To perform the authentication, the RADIUS server uses various EAP methods/protocols, of which there are many.
AXIS P8221 - System Options Network Basic TCP/IP Settings AXIS P8221 supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and at least one version must always be enabled. When using IPv4, the IP address can be set automatically via DHCP, or a static IP address can be set manually. If IPv6 is enabled, the device receives an IP address according to the configuration in the network router. There is also the option of using AXIS Internet Dynamic DNS Service.
AXIS P8221 - System Options Advanced TCP/IP Settings DNS Configuration DNS (Domain Name Service) provides the translation of host names to IP addresses on your network. Obtain DNS server address via DHCP - Automatically use the DNS server settings provided by the DHCP server. Click the View button to see the current settings. Use the following DNS server address - Enter the desired DNS server by specifying the following: • Domain name - Enter the domain(s) to search for the host name used by the device.
AXIS P8221 - System Options Notes: • For NAT traversal to work, this must be supported by the broadband router. The router must also support UPnPTM. • The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadband sharing device” or “Home firewall” but the essential purpose of the device is the same. Enable/Disable – When enabled, the device attempts to configure port mapping in a NAT router on your network, using UPnP™.
AXIS P8221 - System Options QoS Settings - For each type of network traffic supported by your Axis network video product, enter a DSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic’s IP header. When the marked traffic reaches a network router or switch, the DSCP value in the IP header tells the router or switch the type of treatment to apply to this type of traffic, for example, how much bandwidth to reserve for it.
AXIS P8221 - System Options RTP/Audio These settings are the port range, IP address, port number, and Time-To-Live value to use for multicast audio stream(s). Only certain IP addresses and port numbers should be used for multicast streams. For more information please see the online help. Bonjour AXIS P8221 includes support for Bonjour. When enabled, the device is automatically detected by operating systems and clients that support this protocol.
AXIS P8221 - About Information The Server Report and Parameter List may prove useful when troubleshooting a problem or when contacting the Axis support. • • • • • • System Log - Provides information about system events. Access Log - By default, the Access Log lists all failed attempts to access the device but can be configured to list all connections to the device, whether successful or not.
