Hitachi BE-IR31 The BE-IR30/31 are compact and lightweight monochrome board cameras with extended sensitivity and spectral response above 1000 nanometers, allowing use in the near IR range. The cameras are an excellent choice for OEM applications requiring extended spectral response in a very small package. The cameras require only a DC source of power and the optics needed for the application. The BE-IR30 is an internal sync model, while the BE-IR31 is for use with external sync. Standard features include selectable gamma and AGC, along with a multiple speed electronic shutter, and field or frame integration.
