AXIS P32 Dome Camera Series
The device interface
Add subscription
: Click to add a new MQTT subscription.
Subscription filter
: Enter the MQTT topic that you want to subscribe to.
Use device topic prefix
: Add the subscription filter as prefix to the MQTT topic.
Subscription type
:
•
Stateless
: Select to convert MQTT messages into a stateless message.
•
Stateful
: Select to convert MQTT messages into a condition. The payload is used as the state.
QoS
: Select the desired level for the MQTT subscription.
SIP
SIP settings
Session Initiation Protocol (SIP) is used for interactive communication sessions between users. The sessions can include audio
and video.
Enable SIP
: Check this option to make it possible to initiate and receive SIP calls.
Allow incoming calls
: Check this option to allow incoming calls from other SIP devices.
Call handling
•
Call timeout
: Set the maximum time a call can last before it ends if there is no answer (max 10 min).
•
Incoming call duration
: Set the maximum time an incoming call can last (max 10 min).
•
End calls after
: Set the maximum time that a call can last (max 60 min). Select
Infinite call duration
if you don’t
want to limit the length of a call.
Ports
A port number must be between 1024 and 65535.
•
SIP port
: The network port used for SIP communication. The signaling traffic through this port is non-encrypted.
The default port number is 5060. Enter a different port number if required.
•
TLS port
: The network port used for encrypted SIP communication. The signaling traffic through this port is encrypted
with Transport Layer Security (TLS). The default port number is 5061. Enter a different port number if required.
•
RTP start port
: The network port used for the first RTP media stream in a SIP call. The default start port number is
4000. Some firewalls block RTP traffic on certain port numbers.
NAT traversal
Use NAT (Network Address Translation) traversal when the device is located on an private network (LAN) and you want to
make it available from outside of that network.
Note
For NAT traversal to work, the router must support it. The router must also support UPnP
®
.
Each NAT traversal protocol can be used separately or in different combinations depending on the network environment.
•
ICE
: The ICE (Interactive Connectivity Establishment) protocol increases the chances of finding the most efficient
path to successful communication between peer devices. If you also enable STUN and TURN, you improve the ICE
protocol’s chances.
•
STUN
: STUN (Session Traversal Utilities for NAT) is a client-server network protocol that lets the device determine if
it is located behind a NAT or firewall, and if so obtain the mapped public IP address and port number allocated for
connections to remote hosts. Enter the STUN server address, for example, an IP address.
•
TURN
: TURN (Traversal Using Relays around NAT) is a protocol that lets a device behind a NAT router or firewall receive
incoming data from other hosts over TCP or UDP. Enter the TURN server address and the login information.
