Ryan,
Several years ago I used WebcamXP, then Webcam7 with Foscam cameras, which are very similar to Amcrest. The program then became Netcam Studio and I used it with both Foscam and Amcrest cameras.
About 4 years ago I started using Blue Iris to stream all my cameras. I currently stream 6 Amcrest cameras and a Wyze camera. Blue Iris is a great product with great support.
