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 via a web console with 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 level, the 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.

63E-M, SD8363E specifications

The Vivotek SD8363E and SD8363E-M are advanced outdoor-speed dome network cameras designed to provide high-performance surveillance in various environments. Both models are engineered to deliver reliable monitoring solutions, characterized by their robust design and exceptional technological features.

One of the standout features of the SD8363E series is its superior image quality. Equipped with a 2-megapixel sensor, these cameras are capable of delivering vivid, high-resolution images at 30 frames per second. The combination of WDR (Wide Dynamic Range) technology and IR (Infrared) illumination enhances their capability to capture clear images even in challenging lighting conditions, such as backlit scenes or during nighttime.

The cameras are designed for versatile monitoring with a powerful 30x optical zoom lens, enabling users to focus on distant subjects while maintaining sharp detail. This feature is particularly beneficial for large areas where fine details are crucial for identification purposes. The built-in P-Iris provides precise control over the aperture, thus optimizing depth of field, image clarity, and quality in various lighting conditions.

Furthermore, the Vivotek SD8363E and SD8363E-M are equipped with advanced network technology, including H.264 compression. This technology allows for reduced bandwidth and storage requirements while maintaining high video quality. The cameras support Power over Ethernet (PoE), simplifying the installation process by allowing the power and data to be transmitted through a single cable.

Another noteworthy characteristic is the intelligent video analytics feature incorporated into these models. Users benefit from automated capabilities such as motion detection, tampering detection, and a variety of customizable event triggers. These functionalities enhance the efficiency of surveillance operations, saving time and resources.

The design of the SD8363E-M variant includes additional features suited for various environmental challenges, such as IP66-rated and IK10-rated housing, ensuring resistance to harsh weather conditions and vandalism. This makes the SD8363E-M an ideal choice for outdoor installations in urban areas or high-risk environments.

In summary, the Vivotek SD8363E and SD8363E-M are cutting-edge surveillance solutions that integrate high-resolution imaging, powerful zoom capabilities, efficient compression technology, and robust environmental protection. These features make them suitable for a wide range of applications, from urban monitoring to commercial security.
