Server side functions
Server side functions detect motion within an image, tampering attempts on the camera, and differences to a reference image. For server side functions, images are analyzed by motion detection modules on the server (see Adding server-based motion detection module). For example, a server side motion detection event can be used to trigger an alarm scenario.
Server side image analysis by the motion detection module can result in high resource load. Therefore it is recommended to use the camera side motion detection (see Camera side functions).
- Select the 'Server side functions' menu item.
- Select a video classification (see Video streams). The video classification determines which video stream is used for motion
detection analysis. The default video classifications are ordered according to their use of network bandwidth ("HD quality" requires a broadband connection, whereas "Mobile" decreases the image quality for slow networks. But remember that you can modify these labels). For image comparison, select a video stream for low bandwidths. Motion detection, reference image comparison and tampering resize the images to 320x240 pixels internally if they are larger.
