There isn't any manual method to add a camera because this software is developed to automatically detected any connected camera. Any-Guard Recorder works only with USB cameras and can recognize maximum 4 connected devices. In order to fix the issue, go to Start, type Device Manager in the Search programs and files field and open the utility. Locate the USB camera, right-click on its driver and select Uninstall. After that, reboot your PC, connect the camera and click the Scan for hardware changes icon from Device Manager. If Any-Guard Recorder still doesn't recognize the camera, it means that your device is incompatible with the software.
