Network > QoS (Quality of Service)

Advanced Mode

Quality of Service refers to a resource reservation control mechanism, which guarantees a certain quality to different services on the network� Quality of service guarantees are important if the network capacity

is insufficient, especially for real-time streaming multimedia applications. Quality can be defined as, for

instance, a maintained level of bit rate, low latency, no packet dropping, etc�

The following are the main benefits of a QoS-aware network:

The ability to prioritize traffic and guarantee a certain level of performance to the data flow.

The ability to control the amount of bandwidth each application may use, and thus provide higher reliability and stability on the network�

Requirements for QoS

To utilize QoS in a network environment, the following requirements must be met:

All network switches and routers in the network must include support for QoS�

The network video devices used in the network must be QoS-enabled�

QoS models

CoS (the VLAN 802�1p model)

IEEE802�1p defines a QoS model at OSI Layer 2 (Data Link Layer), which is called CoS, Class of Service� It adds a 3-bit value to the VLAN MAC header, which indicates the frame priority level from 0 (lowest) to 7 (highest)� The priority is set up on the network switches, which then use different queuing disciplines to forward the packets�

Below is the setting column for CoS� Enter the VLAN ID of your switch (0~4095) and choose the priority for each application (0~7)�

If you assign Video the highest priority level, your network switch will handle video packets first.

NOTE:

A VLAN Switch (802.1p) is required. Web browsing may fail if the CoS setting is incorrect.

Class of Service technologies do not guarantee a level of service in terms of bandwidth and delivery time; they offer a “best-effort.” Users can think of CoS as “coarsely-grained” traffic control and QoS as “finely-grained” traffic control.

Although CoS is simple to manage, it lacks scalability and does not offer end-to-end guarantees since it is based on L2 protocol�

IP8352 specifications

The Vivotek IP8352 is a versatile and high-performing network camera designed for a range of surveillance applications. With its sleek and compact design, it caters to both indoor and outdoor installations, making it a popular choice for businesses and homeowners alike.

One of the standout features of the IP8352 is its exceptional image quality. Equipped with a 2-megapixel sensor, it delivers high-definition video at resolutions up to 1920x1080 pixels. This ensures clear and detailed images, even in challenging lighting conditions. The camera also supports WDR (Wide Dynamic Range) technology, enabling it to capture balanced images in scenes with both bright and dark areas.

The IP8352 boasts an advanced IR-cut filter which allows it to capture clear images both day and night. With built-in IR illuminators, the camera can deliver black and white video up to 30 meters at night, providing continuous surveillance even in complete darkness.

Another impressive characteristic is the camera’s ability to provide real-time video streaming. It supports multiple video compression formats, including H.264 and MJPEG, facilitating efficient bandwidth usage without compromising quality. This feature is essential for systems where network resources are limited, allowing users to adjust the streaming settings based on their needs.

The Vivotek IP8352 is also equipped with Smart Stream technology, which optimizes bandwidth efficiency by allowing users to prioritize specific regions within the camera's field of view. This means that critical areas can be monitored more closely while other less important sections can use lower resolution, saving on storage and bandwidth.

Additionally, the camera features an IP66-rated housing, ensuring that it is dust-tight and capable of withstanding heavy rain and harsh environmental conditions. This durability makes it suitable for various applications, from retail stores to warehouses and outdoor settings.

In terms of installation, the IP8352 supports Power over Ethernet (PoE), simplifying the installation process by allowing both power and data to be delivered through a single cable.

Overall, the Vivotek IP8352 combines high-definition video quality, advanced surveillance technologies, and robust construction, making it a highly effective solution for modern security needs. Its flexibility and features make it an ideal choice for enhancing security in diverse environments.
