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 prioritization from 0~7 (Eight different classes of service are available). 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.

IK-WD12A specifications

The Toshiba IK-WD12A is a high-performance network camera designed to meet the surveillance needs of a variety of environments, including commercial, industrial, and retail settings. This model stands out in the competitive market of IP cameras due to its robust set of features and advanced technologies, making it a reliable choice for users seeking security solutions.

One of the primary features of the IK-WD12A is its high-definition video resolution. With the capability to deliver up to 720p (1280x720) video, this camera ensures clear and detailed images, allowing for effective monitoring and identification of subjects. The camera's 1/4-inch CMOS sensor is designed to perform well under different lighting conditions, making it suitable for both day and night surveillance.

Another key characteristic of the IK-WD12A is its wide dynamic range (WDR) technology. This feature enhances image quality in scenes with varying light levels, preventing overexposure and underexposure. As a result, users can expect consistent and clear video footage in challenging lighting conditions, such as during dawn or dusk when the contrast between shadows and bright light can be significant.

The Toshiba IK-WD12A is equipped with multiple streaming capabilities, allowing users to access video feeds simultaneously on different devices. This is particularly useful for security personnel who may need to monitor several locations at once. The camera supports H.264 compression, which reduces file sizes while maintaining video quality, ensuring efficient storage and bandwidth usage.

Another significant advantage of the IK-WD12A is its ease of installation and integration into existing security systems. The camera is compatible with various network protocols and can be easily connected to a range of software platforms, enabling users to customize their surveillance setup according to their needs.

In terms of design, the IK-WD12A is compact and versatile, making it suitable for both indoor and outdoor applications. Its sturdy construction is resistant to harsh environmental conditions, ensuring reliable operation even in challenging settings.

Overall, the Toshiba IK-WD12A network camera combines high-quality video performance, advanced imaging technologies, and user-friendly features, making it a solid choice for those looking to enhance their security infrastructure.
