Network > QoS (Quality of Service)

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-capable 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.

SF8174 specifications

The Vivotek SF8174 is a powerful and versatile network camera designed for advanced surveillance applications. It combines cutting-edge technology with high-performance features to deliver exceptional video quality and reliability in various environments.

One of the standout features of the SF8174 is its 4MP resolution, which provides crisp, detailed images that meet the demands of modern surveillance. The camera boasts a large variety of resolutions and frame rates, enabling users to customize their settings based on the specific requirements of their monitoring area.

Equipped with a 3.6mm fixed lens, the SF8174 offers a wide field of view, making it ideal for large spaces such as parking lots, warehouses, and retail stores. Furthermore, the camera supports advanced features such as WDR (Wide Dynamic Range) technology, which compensates for challenging lighting conditions, ensuring that details are captured accurately in both bright and dark areas of the scene.

The SF8174 also supports H.265 video compression technology, significantly reducing bandwidth and storage space requirements while maintaining high video quality. This innovative compression method allows users to store more footage over an extended period without compromising video clarity, making it a cost-effective solution for long-term surveillance needs.

In terms of durability, the camera is built to withstand harsh conditions, with an IP66 rating that ensures resistance against water and dust. This feature makes the SF8174 suitable for outdoor deployment in various weather conditions. Additionally, its robust design includes a vandal-resistant housing, providing extra protection in high-risk areas.

Another key characteristic of the SF8174 is its smart analytics capabilities. The camera is equipped with features such as motion detection, tampering detection, and line-crossing detection. These intelligent functions help improve surveillance efficiency by sending real-time alerts to users when suspicious activity is detected, thereby enhancing the overall security of the monitored area.

The Vivotek SF8174 is also compatible with various management software solutions, including Vivotek's own VAST and third-party systems. This compatibility allows for seamless integration into existing surveillance setups, enabling users to manage their cameras effectively and tailor their security strategies according to their unique needs.

In summary, the Vivotek SF8174 stands out as a high-performance surveillance solution that blends advanced features, innovative technologies, and durability. With its impressive image quality, intelligent analytics, and robust design, it is well-equipped to meet the demands of diverse surveillance applications across various industries.
