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-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.

FE8171V specifications

The Vivotek FE8171V is a cutting-edge fisheye network camera designed to deliver high-quality surveillance in a compact and efficient form factor. Renowned for its advanced technologies and features, this camera is well-suited for a variety of applications, including retail, transportation, and public spaces.

One of the standout characteristics of the FE8171V is its 5-megapixel resolution, which ensures crystal-clear image quality. This high resolution allows users to capture vibrant details even in expansive scenes, making it ideal for monitoring large areas without the need for multiple cameras. The camera is equipped with a fisheye lens that provides a 360-degree panoramic view, eliminating blind spots and maximizing situational awareness.

The Vivotek FE8171V also excels in its low-light performance. With built-in infrared (IR) illumination, it can capture clear images in low-light conditions, providing 24/7 surveillance capability. The camera features WDR (Wide Dynamic Range) technology, which balances bright and dark areas within a scene, allowing for better visibility in challenging lighting situations, such as entrances and exits.

For enhanced data management, the FE8171V supports the H.265 video compression standard, which significantly reduces bandwidth and storage requirements while maintaining high-quality video output. This feature is particularly beneficial for organizations looking to optimize their surveillance infrastructure.

Additionally, the camera integrates seamlessly with Vivotek’s Smart Stream technology, which intelligently allocates bandwidth for crucial video streams while conserving resources for less critical footage. This ensures that essential details are captured without overwhelming the network.

Durability and reliability are also key elements of the FE8171V. The camera is designed with a sturdy housing that is resistant to vandalism and adverse weather conditions, making it suitable for outdoor as well as indoor installations. With an IP66 rating, it can withstand rain, dust, and other environmental factors, ensuring uninterrupted operation.

Another significant feature is its easy installation process. The FE8171V is designed for flexible mounting options, allowing users to position the camera in a variety of settings to achieve optimal coverage.

In summary, the Vivotek FE8171V combines high resolution, advanced imaging technologies, and robust construction to provide an effective surveillance solution for any environment. Its remarkable features make it a valuable addition to security systems, offering peace of mind to users while enhancing overall safety.
