An industrial process control or monitoring system including a control room at a remote location and one or more field devices (14, 16) communicating with the control room, the field device (14, 16) comprising: a0) a controller configured to control operation of the field device in an industrial process; a) wireless communication circuitry configured to wirelessly communicate with the control room at the remote location using a communication protocol which has bandwidth limitations; b) an internal power source configured to wholly power the field device; and c) an image capture device coupled to the controller configured to capture an image of an environment of the field device, including process elements proximate to the field device, which are captured within the image as image information; c1) a memory configured to store image information from images captured by the image capture device; c2) wherein the controller is adapted to retrieve image information from the memory, detect a difference between an image captured by the image capture device and the stored image information, d) wherein the controller is further adapted to compress the image information and transmit compressed image information to the remote location based upon the detected difference between the image captured by the image capture device and the stored image information, thereby reducing communication bandwidth used to transmit image information to the remote location and reduce power consumed by the wireless field device from the internal power source; e1) wherein the image capture device is adapted to capture a first image of the environment of the field device (14, 16) at a first time, the memory is adapted to store the first image as a reference image, and wherein the reference image is also stored at the control room at the remote location; e2) wherein the image capture device is further adapted to capture a second image of the environment of the field device (14, 16) at a subsequent second time, e3) wherein the controller is adapted to, for detecting a difference between the second image captured by the image capture device and the stored reference image, identify changes between the two images and only store as delta image information those portions which have changed, and e4) wherein the controller is adapted to transmit to the remote location, as said compressed image information, the delta image information after compressing same. a0) a controller configured to control operation of the field device in an industrial process;
