+<h2>Grabber camera interface</h2>
+<p>Grabber allows the connection of certain scientific (EM)CCD cameras port to the core FPGA. Those cameras use a Camera Link interface.</p>
 
 <p>In the FPGA, frame data streamed through "ROI engines". Each ROI engine gates on one rectangular pixel region and accumulates pixel values for each frame. The ROI engines operate independently and can be overlapping. After the frame, the accumulated value is pushed as an RTIO input event. Regions of interest (ROI) can be configured at runtime, and are defined with the computer.</p>
