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 level, the switch will handle video packets first.

NOTE

The VLAN Switch (802.1p) is required. The 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.

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

FD8361L specifications

The Vivotek FD8361L is a sophisticated network camera designed specifically for outdoor surveillance and monitoring applications. It is part of the FD series, which is renowned for its reliability and high-performance features. The FD8361L boasts a robust and elegant design, making it suitable for various environments while providing excellent video quality and performance.

One of the standout features of the FD8361L is its 2-megapixel resolution, which delivers high-definition images and ensures clear and detailed video capture. This camera can record at a frame rate of up to 30 frames per second (fps) at 1080p, suitable for fast-moving objects and dynamic scenes. This high-performance video capture is crucial for security applications, allowing for accurate identification and monitoring.

The camera is equipped with WDR Pro (Wide Dynamic Range) technology, enabling it to perform well in challenging lighting conditions. This feature helps to balance the exposure levels in environments where both bright and dark areas are present, ensuring clear visibility without overexposed highlights or underexposed shadows.

Another significant characteristic of the FD8361L is its Infrared (IR) functionality, which provides night vision capabilities. With built-in IR LEDs, the camera can capture clear images even in total darkness, reaching distances of up to 30 meters. This ensures 24/7 surveillance, making it ideal for areas requiring constant monitoring.

In terms of durability, the FD8361L is constructed with an IP66-rated housing, making it weatherproof and resistant to harsh environmental conditions such as rain, wind, and dust. Additionally, it is equipped with a robust metal casing that provides extra protection against vandalism, making it suitable for outdoor installations in high-risk areas.

The FD8361L also supports Power over Ethernet (PoE) technology, allowing for simpler installation by enabling power and data transmission through a single cable. This feature reduces the need for additional power sources, streamlining setup and operation.

With advanced features like smart stream technology, which optimizes bandwidth usage by adjusting the quality of streaming video, this camera ensures efficient data transmission without compromising image quality. Furthermore, it supports various video compression formats, including H.264 and MJPEG, allowing for flexibility in network and storage configurations.

Overall, the Vivotek FD8361L is a versatile and high-performing network camera influenced by contemporary surveillance needs, providing significant contributions to security and monitoring in diverse applications. Its combination of excellent image quality, advanced technologies, and durable design makes it an excellent choice for both residential and commercial surveillance solutions.
