AXIS Q1755/-E - System Options
RTSP
The RTSP protocol allows a connecting client to start an H.264 stream. Check the box to enable the server and enter the RTSP port number to use. The default setting is 554. Note that H.264 video streams will not be available if this service is not enabled.
SOCKS
SOCKS is a networking proxy protocol. The Axis network camera can be configured to use a SOCKS server to reach networks on the other side of a firewall/proxy server. This functionality is useful if the network camera is located on a local network behind a firewall, and notifications, uploads, alarms, and such need to be sent to a destination outside the local network (such
as the Internet). See the online help 
for more information.
QoS (Quality of Service)
Quality of Service (QoS) guarantees a certain level of a specified resource to selected traffic on a network. Quality can be defined as a maintained level of bandwidth, low latency, and no packet losses. The main benefits of a
•The ability to prioritize traffic and thus allow critical flows to be served before flows with lesser priority.
•Greater reliability in the network, thanks to the control of the amount of bandwidth an application may use, and thus control over bandwidth races between applications.
The QoS in Axis network video products marks the data packets for various types of network traffic originating from the product. This makes it possible for network routers and switches to reserve a fixed amount of bandwidth for these types of traffic. The network cameras mark the following types of traffic:
•video
•audio
•event/alarm
•management network traffic
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. Note that DSCP values can be entered in decimal or hex form, but saved values are always shown in decimal.

SMTP (email)
Enter the host names (or IP addresses) and port numbers for your primary and secondary mail servers in the fields provided, to enable the sending of notifications and image email messages from the camera to predefined addresses via SMTP.
If your mail server requires authentication, check the box for Use authentication to log in to this server and enter the
necessary information. See the online help 
for more information.
SNMP
The Simple Network Management Protocol (SNMP) allows remote management of network devices. An SNMP community is the group of devices and management station running SNMP. Community names are used to identify groups.
Depending on the level of security required, select the version of SNMP to use.
SNMP v1/v2
Select either SNMP V1 that includes no security, or SNMP V2c that uses very simple security.
The community name can be specified as a password for read or read/write access to all supported SNMP objects. The community is the group of network devices using SNMP. The default password for the Read Community is public and the default password for the Write community is write.
