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.

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

IK-WD05A specifications

The Toshiba IK-WD05A is a high-performance network camera designed for versatile surveillance applications. Built for reliability and superior image quality, this camera is particularly suited for both indoor and outdoor monitoring environments.

At the heart of the IK-WD05A is a 1.3 Megapixel CMOS sensor that captures high-definition video with resolution up to 1280x1024 pixels. This ensures crystal clear images even in varying lighting conditions, making it ideal for a range of security needs. The camera utilizes advanced image processing technology to enhance clarity and reduce noise, producing high-quality images at all times.

One of the standout features of the Toshiba IK-WD05A is its impressive low-light performance. With a minimum illumination of just 0.3 lux, the camera can capture usable images even in dimly lit environments. This capability is further enhanced by its built-in infrared (IR) LED illuminators, which enable night vision up to 30 meters, ensuring 24/7 surveillance regardless of lighting conditions.

The IK-WD05A supports a range of compression formats, including H.264 and MJPEG, which optimize bandwidth usage while maintaining high-quality video streams. This feature is particularly beneficial for users who need to remotely monitor live feeds without overwhelming their network with large data transfers.

Additionally, the Toshiba IK-WD05A offers exceptional flexibility with its pan, tilt, and zoom capabilities. Users can easily adjust the camera's field of view to focus on specific areas, making it an ideal choice for monitoring busy locations or wide-open spaces. The camera comes equipped with a motorized zoom lens, providing a powerful optical zoom that allows for detailed inspection of distant objects.

Integration is another strong suit of the IK-WD05A. The camera is compatible with various video management systems, allowing for seamless connectivity and remote access from multiple devices. This feature empowers users to manage their surveillance system effectively, with customizable settings and alerts directly from their smartphones or tablets.

Furthermore, the Toshiba IK-WD05A is designed with durability in mind. It is built to withstand harsh environmental conditions with an IP66 rating for weather resistance. This feature ensures that the camera remains operational even in extreme temperatures and adverse weather, making it suitable for outdoor installations.

In summary, the Toshiba IK-WD05A combines high-resolution video quality, outstanding low-light performance, and versatile installation options. Its advanced technologies and robust features make it a formidable choice for anyone seeking a reliable surveillance solution. Whether for residential, commercial, or industrial applications, the IK-WD05A delivers consistently high performance tailored to meet diverse surveillance needs.
