BNotes on Face Priority

•When Face priority is selected for AF area mode, the setting will automatically switch to Auto if no face is detected when the shutter-release button is pressed halfway.

•If no face is recognized when the shutter-release button is pressed halfway in the Portrait or Night portrait scene modes or smart portrait mode, the camera will focus on the subject in the center of the frame.

•Depending on shooting conditions, such as whether or not the subject is facing the camera, faces may not be detected.

•The camera may be unable to detect faces in the following situations:

-When faces are partially hidden by sunglasses or other obstructions

-When faces take up too much or too little of the frame

•When there are multiple people in the frame, the face on which the camera focuses depends on a variety of shooting conditions, such as whether or not the subject is facing the camera.

•In some rare cases shooting subjects with which autofocus may not perform as expected (A 29),

the subject may not be in focus despite the fact that the double border glows green. Should this occur, switch to auto mode and set AF area mode to Manual or Center, refocus on another subject positioned at the same distance from the camera as the actual portrait subject, and use focus lock (A 105).

•Images that were taken using face priority will be rotated and displayed automatically according

to the orientation of the faces detected, in full-frame and thumbnail playback modes (excluding pictures that were shot using Continuous, BSS and Multi-shot 16 (A 101)).

One of the primary characteristics of the S640 is its advanced switching capabilities. It operates at Layer 2 and Layer 3, making it suitable for diverse network topologies. The switch is capable of managing a high volume of data traffic efficiently due to its scalability, accommodating growing network needs without compromising performance.

The S640 is equipped with Power over Ethernet (PoE) technology, which simplifies the deployment of connected devices like IP cameras and VoIP phones. This feature not only reduces the need for separate power supplies but also enhances installation flexibility.

Another vital feature of the S640 is its support for Quality of Service (QoS). This functionality ensures that critical applications receive priority over less essential traffic, leading to improved performance for services such as voice and video over the network. QoS management is especially crucial in business environments where it is necessary to maintain operational efficiency and user satisfaction.

Security is paramount in modern networks, and the S640 addresses this with a range of integrated security features. It supports advanced authentication mechanisms such as IEEE 802.1X, ensuring that only authorized devices can access the network. Additionally, features like virtual LAN (VLAN) support help isolate different segments of network traffic, bolstering security and management capabilities.

The S640 also emphasizes energy efficiency, making it an environmentally friendly option for enterprises concerned about their carbon footprint. Nortel has designed this equipment to meet various energy standards, reducing consumption while delivering optimal performance.

In summary, the Nortel Networks S640 stands out in the crowded networking market through its powerful switching capabilities, support for PoE and QoS, robust security features, and commitment to energy efficiency. This combination of characteristics makes it an ideal choice for enterprises looking to upgrade their networking infrastructure to meet contemporary demands.
