Read full description

GhostTube SLS Camera detects humanoid bodies and homogeneous shapes in your environment similar to the way in which a traditional SLS camera works. On devices equipped with Apple's LiDAR technology, GhostTube SLS Camera uses a projected grid of infrared light to detect depth and for better visibility in the dark. Our complex algorithms use data gathered from the camera and depth sensors to detect people and people shaped objects with accuracy that surpasses that of the Kinect SLS cameras. For devices lacking LiDAR, GhostTube will instead rely on dual lens cameras to measure depth in a similar way to how the human eye detects depth - triangulation of objects based on data from multiple lenses. Some light may be required due to the size or lack of sensors depending on the device you're using. Don't pay hundreds or thousands of dollars for a modified gaming console - GhostTube SLS Camera is available FREE for download and can be used as an SLS Camera in all of your paranormal investigations. For more paranormal investigation and ghost hunting tools, check out our other apps. GhostTube offers auto renewable subscriptions. Refer to our website for a full list of terms and conditions, including those relating to auto-renewable subscriptions: GhostTube.com/terms Although GhostTube SLS Camera offers some low light filters, the app is not intended as an aid for seeing in the dark. Always use adequate lighting on your paranormal investigations. Certain shapes and patterns may trigger figures to be mapped by GhostTube SLS Camera.
