The NEC NP-P474U has advanced networking features. Using the projector’s IP address, any computer that is connected to the same IP address can control it via Crestron RoomView. This is a function most often used when controlling more than one projector in a setup, such as when you need to control projectors across multiple classrooms. The NP-P474U comes with NaViSet Administrator 2, another command and control software that accomplishes much of the same thing. And, with Virtual Remote, you can control the projector from a computer using a VGA cable.
The projector also has HDBaseT, which is a standard used for transferring video, audio and control signals over long distances, accomplished by using low cost CAT5e, CAT6, etc., cabling. This standard, developed years ago, is highly useful for placement flexibility and simplifying installation. The source, whether it be a computer, a Blu-ray player, etc., doesn’t need to be near the projector when using HDBaseT, which should provide some peace of mind when determining the positioning of the NP-P474U.
