Section 3: Configuration
Class of Service (CoS) and Quality of Service (QoS) allow you to prioritize surveillance traffic on your network to ensure that your cameras can
stream video smoothly and remain accessible even when there is heavy traffic on your network. Your network must support CoS or QoS in order
to use them. After making any changes, click the Save button to save your changes.
Enable CoS:
Enabling the Class of Service setting implements a best-effort policy to
prioritize traffic without making any bandwidth reservations.
To use CoS, enable it, enter the VLAN ID to use for the camera, and set the
priority for your Live Video, Live Audio, Event/Alarm, and Management
camera traffic.
Enable QoS:
Enabling QoS allows you to specify a traffic priority policy to ensure a
consistent Quality of Service during busy periods. If the Network Camera is
connected to a router that itself implements QoS, the router's settings will
override the QoS settings of the camera.
To use CoS, enable it and set the priority for your Live Video, Live Audio,
Event/Alarm, and Management camera traffic.
