It will take a few seconds for the camera to be recognized after it is connected to the system. To ensure the camera has been installed correctly on a Windows computer, check under Control Panel > System and Security > Device Manager.

To verify the webcam is connected on a Mac computer, click the Apple Menu (in the top left corner of your screen) and then click About this Mac. Click on System Report from the pop-up window that appears. The System Information window for your Mac will appear. Navigate to the USB section and check if the webcam is listed as a connected device (like the photo below):

The NexiGo webcam captures clear images and can record video at 4K@30fps, or 1080p@60fps in a well-lit environment. The quality of the signal can be affected by low bandwidth availability or insufficient lighting. This can cause the frame rate to drop to 4K@20fps, or 1080p@50fps, or possibly even lower.
Please ensure that the light in your environment isfree of unique tones or intense light sources. Things such as walls / floors / other large-area non-standard light sources, including areas with colored or intense light. In such environments photographed pictures are subjected to color cast due to the lighting impact of these light sources.
For Windows & Mac:
Using the NexiGo Webcam Settings Software, you can adjust the image parameter you want according to your needs.
Note: Download the NexiGo Webcam Settings Software from nexigo.com/software.
Check the video output settings in your video capture software, these may be set to a lower capture format. There are various constraints on the system that could impede the ability to attain a 4K video calling session. They center around processing power (i.e., CPU speed) and available network bandwidth. In all cases, review the requirements from the video calling application. They will guide as to the system performance required as well as the necessary bandwidth.
The webcam cannot support 4K resolution, 60fps, and digital zoom simultaneously.
Unless you have issues with the camera, we don't recommend any firmware updates. If you are not sure about if updates are needed, please contact our customer support cs@nexigo.com.
