The ez-bnc converts a composite BNC or s-video signal into a VGA signal. What sets it apart from other converters is the scaling function. The ez-bnc can scale BNC and s-video video sources to a resolution of 1280x1024. This device also features VGA pass-through, which allows you to still be able to use the VGA monitor with a PC if needed, and switch between the BNC input and VGA input.
