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�

FD8162 specifications

The Vivotek FD8162 is a high-performance fixed dome network camera designed to deliver exceptional video surveillance capabilities, making it an ideal choice for various indoor applications, such as retail environments, offices, and public spaces. This camera stands out due to its compact design and advanced features that cater to the needs of modern security systems.

One of the key features of the FD8162 is its 2-megapixel Full HD resolution, which provides clear and detailed video quality at 30 frames per second. This high resolution ensures that critical details are captured, enabling users to identify individuals and recognize activities with ease. The camera is equipped with a 3.6 mm fixed lens, offering a wide field of view, which is essential for monitoring larger areas without compromising on image quality.

The FD8162 incorporates advanced image processing technologies, including WDR (Wide Dynamic Range) and 3D noise reduction. WDR technology significantly improves image quality in environments with challenging lighting conditions, allowing the camera to capture clear images in both bright and dark areas simultaneously. Meanwhile, 3D noise reduction enhances low-light performance, making it suitable for 24/7 surveillance.

Another notable characteristic of the Vivotek FD8162 is its efficient storage management capabilities. The camera supports H.264 compression, which minimizes bandwidth usage and storage requirements while maintaining high-quality video streams. This feature is particularly beneficial for users with limited storage capacity, as it ensures efficient use of resources.

Vivotek has also designed the FD8162 with durability in mind. The camera is housed in a compact and robust casing that is resistant to impacts, ensuring reliability and longevity in various environments. Additionally, the camera is equipped with an IP66-rated weatherproof enclosure, making it suitable for deployment in a variety of settings, whether indoors or in sheltered outdoor areas.

Security and ease of use are further enhanced through the integration of Power over Ethernet (PoE) technology, which simplifies installation by allowing the camera to receive power and network connectivity through a single cable. This reduces clutter and simplifies wiring, making setup easier for users.

In conclusion, the Vivotek FD8162 is a versatile and reliable surveillance camera that combines high-resolution video quality, advanced imaging technologies, and durable design. Its features make it an excellent choice for those seeking an efficient and effective security solution for various indoor monitoring applications.
