GhostTube SLS is a powerful camera/sensor, which detects the presence of humans and human-shaped objects. It works with any device that is equipped with Apple’s LiDAR technology. If your device doesn't have this technology, the app will utilize the phone's dual cameras.  It is a useful tool for the investigation of paranormal activity. 

Using complex algorithms, the GhostTube SLS camera detects human bodies and human-shaped objects in your environment. It is an advanced and accurate SLS camera for iOS devices. It has a depth sensor that works using an infrared projector and is more accurate than that of a Kinect.
