Why is my camera out of focus?
The VTWC40 is an auto focus camera. Move your hand in front of the camera and pull it back towards you
body for the sensor to find a focal point.
The VTWC30 is a manual focus camera. To adjust the focus, rotate the knob that houses the camera lens
until you achieve the desired focus.
The VTWC20 is a fixed focus camera and will always have a consistent focal distance which means you may
need to adjust the distance between you and the webcam for best results. Be sure to open the camera
application on your system to help determine when the focus is set in the proper location.
Is there a way to adjust the brightness of the video when under bright lights?
The webcams come standard with advanced built-in parameter adjustment chips. When the video is too
bright, face the camera at the ceiling or white wall so that the camera can automatically reduce brightness.
Readjust the camera back to its original position and the video will revert to normal brightness.
Why am I getting horizontal lines in images?
The horizontal lines are caused by light refraction. If you adjust the angle of the camera, the screen will come
back to normal. Some overhead LED lighting systems may also cause the horizontal lines, there is no way to
fix this besides turning off the lights.

Why is my webcam acting slow or there is a delay in the image?
Try restarting your computer as this may solve the issue. Ensure that the webcam is recognized properly in
Windows Device Manager or MacOS System Report. If the issue happens only while using your video chat
application, check your internet connection bandwidth and/or adjust the quality settings in your video chat
application. Make sure that the webcam is connected directly to a High-Speed USB 2.0 or 3.0, preferably the
one at the rear if you are using a desktop computer.Connect the webcam directly to the computer. Try to
bypass your Dock, USB hub, USB extension cable, USB port of monitor or keyboard. If you still experience
problems, try connecting the webcam to another computer.
