Does Pearl reduce the resolution of the images it captures?

Pearl by default, preserves the original resolution of the images captured and matches the output frame size of with the resolution of the source. Pearl can also perform real time scaling of the incoming source resolution and render it to the frame size chosen in the stream setup configuration menu. When creating picture-in-picture layouts with two sources, you can change the resolution for each source.

Can Pearl function over a Local Area Network (LAN) or does it need a constant connection to the Internet?

Pearl does not need LAN or Internet connection to capture and record images. Pearl functions as a stand-alone device or connected to the Ethernet port of a computer. The user-friendly, touch screen displays the video stream for confidence monitoring and provides a fast and easy way to control recording and view system information. If connected to a a computer by Ethernet cable or to a LAN or the Internet, Pearl provides a web-based control interface for configuration and operation.

The video mode or source resolution that I am using is not listed in the list of supported modes for Pearl.

Pearl analyzes the source signals to automatically determine the incoming source resolution. If Pearl doesn’t correctly match the incoming resolution, you can input a custom resolution through the web interface. If Pearl does not support the resolution you provide, please contact us. We are always looking for ways to improve our products to add support for this mode.
