FIGS. 21-22 provide an embodiment of the monitor 114, which can be used with the reels 26, 26a illustrated herein. The monitor 114 is configured to engage with the clip 262 on the mount 110a. Specifically, the monitor 114 includes a set of rails 268 that form a channel 272. The rails 268 and the channel 272 of the monitor 114 are configured to slidably engage with the rails 260 and the channel 264 on the clip 262 portion of the mount 110a. Thus, the monitor 114 can be slid onto the clip 262 to be supported on the reel 26a. The monitor 114 includes a display device 266 for viewing an image or video captured by the camera 18, and a user interface 270 for controlling the camera 18 and/or the display device 266. In some embodiments, the user interface 270 may be a separate device from the display device 266. For example, the user interface 270 may be on a user mobile device, such as through an application on a phone. This may allow a user to control the operation of the pipeline inspection device 10 through the application on the phone. In some embodiments, the monitor 114 is a dedicated monitor specifically configured to only work with the pipeline inspection system. In other embodiments, the monitor 114 is embodied as a separate electronic device, such as a laptop, a smartphone, a tablet computer, or the like. In such embodiments, the separate electronic device may also embody the user interface 270 such that the user interface 270 and the monitor 114 are embodied by the same electronic device. The separate electronic device may be configured to communicate with other devices (e.g., the hub 30) over a wired or wireless communication interface as indicated in FIGS. 23 and 24.
