Software clients suitable for personal usage on PC or MAC require web camera and headphones with microphone. We recommend high-quality components because the quality of the image and the sound (good microphone) is the critical aspect of high-quality telephony or video conferencing. It is natural that quality of web cameras is bellow the quality of cameras used in hardware units. Nevertheless, they are sufficient fo the personal usage and mainly they are cheaper. It is also possible to use camera embedded in notebook display frame, but its quality is bellow the quality of external web camera (for example, Logitech Webcam 920, Microsoft Lifecam Studio) and they do not allow any rotation without the change of position of the display which can be a disadvantage.

Recommended web cameras for personal software SIP/IP telephone clients are:

• Microsoft LifeCam Studio
• Logitech Webcam c920
• Logicech Webcam c615

Quality headphones with microphones are necessary for the elimination of echo and for restricting the noise of surroundings. It is important for the microphone to record only the voice of attendee without the surroundings because surroundings do not have to be quiet. Headphones will restrict the noise of surroundings in time of teleconferencing or video conferencing and attendee's hands are free. Because teleconferencing and video conferencing can often last few hours the quality headphones assure certain comfort for the user. External microphone with restricted feedback (for example, Clearone Chat 150) can be added to software client. This device is necessary in a case of more attendees teleconferencing or video conferencing in same room.
