## Abstract

Devices, methods, and systems for monitoring captured images and/or video from one or more cameras are described herein. The systems may include one or more cameras, a video recorder, a mobile display device, and a location detection system. The location detection system may detect a proximity of the mobile display device relative to one or more cameras and determine when the proximity to a camera meets a predetermine proximity criteria. The mobile display device may display at least part of a recorded video stream that is captured by the camera when it is determined the proximity of the mobile display device to the camera meets the predetermined proximity criteria. In some cases, the displayed video may be displayed in a virtual reality or three dimensional format. Further, as the proximity of the mobile display device to the camera changes, a zoom level and/or direction of view of the displayed video may change.
