The Sony PlayStation Portable gaming system has a Universal Serial Bus port, which allows it to accept different peripherals. As of 2011, the two types of accessories that have been produced to work with the PSP USB port are a Global Positioning System satellite receiver and cameras. The Next Generation Portable gaming system from Sony will include GPS and a camera as standard features.
Sony controls the operation of the USB peripheral port on the PSP gaming system through the use of firmware loaded into the PSP. This prevents any unauthorized USB devices from accessing the PSP's operating system. After firmware update 3.01, the camera feature was enabled. Because of this, only a few Sony-authorized cameras will work with the PSP.
The Go!Cam is a stand-alone camera product, designed for PAL regions, that allows you to record video and take still images with your PSP. It plugs into the USB port on the top of your PSP and receives its power directly through the USB plug. This device offers the ability to interact with any PSP games that can use a camera, such as "EyePet." With the Go!Cam you can take pictures of yourself and others to use as avatars in your gaming, capture video on the go, and then load the images and videos to your computer with the Sony Memory Stick.
"EyePet" is an augmented reality game where you get to introduce an electronic pet to your real-world environment through the use of the PSP-compatible camera that is included with the game. The camera included with the "EyePet" game also lets users take video and still shots with the PSP.
The PSP-300X and the later PSP-450X, which were sold in Japan and North America, provided video and photograph functionality. The Go!Cam is the European version of the PSP-450X. The PSP-300X and PSP-450X provide the same features of capturing video and still images that can be used in games as well as transferred to a computer.
