The video camera should show a close-up of the conference participants. Place it above the monitor, 15 or less degrees above the line connecting your eyes and the center of the screen. Such an installation will provide eye-to-eye contact.

Equip a room for video conferencing
Video conferencing room is your face to remote subscribers, so its design is very important. But the room VKS is not only a way to show you from the best side. For a clean, legible sound and video, you need to make a competent lighting and take into account the layout of the room. Here are some basic tips on how to properly equip a room for video conferencing.
Lighting
Do not use directional lights or studio spotlights to illuminate the room; this will have a negative effect on people's faces.
To prevent participants from seeing shadows, use non-directional fluorescents with a brightness of at least 740 Lux. Ideally, if the color temperature of the lamps is 3200-3400K, it will provide the natural color of the faces of the participants. The more light sources in the room, the better.
Do not use both incandescent and fluorescent. If the room has windows, be sure to use thick curtains, in extreme cases - blinds. Otherwise, the sun and the street light will negatively affect the image of the room (glare will appear, colors will change, etc.).
Furniture and furnishings
Choose comfortable chairs. Install them in strictly designated places, in the area of ??view of the camera. It is desirable to use a dark table with a matte surface, rectangular, trapezoidal or special shape (Fig. 6).
In the background of the room (Background), place the company logo and the clock showing local time.
Sound
Many video communication systems have built-in microphones with support for the “voice guidance” function. Use this function if the speaker is within a radius of 2 ... 3 meters from the video conferencing system . For small groups of users, use group desktop microphones. Position the microphone at a distance of 3 ... 4 meters from the display screen. One group microphone is enough for 4 ... 6 participants.
If the room for video conferencing is large and there are a lot of participants, installation of individual microphones (desktop or embedded) is required. If the speaker is single, a lavalier microphone is used (on the lapel of the jacket).
Interior decoration
The most important wall in the room for video conferencing is the back (background) wall, which is directly opposite the video camera. There should be no windows, distractions, doors or moving people in the background.
In the decoration of the room, avoid red and variegated colors, as they can flicker or flicker on the screen. Avoid black and bright white. People’s faces may look blurry against a background of brown and yellow-brown. The best colors for the background are blue or blue-green. Also suitable: matte white or beige, light gray, light blue.
The screen looks good finishing materials with a soft texture. Avoid shiny surfaces and glass objects (glasses, glasses) that reflect both light and sound. business video conferencing slutions in chennai
