As shown in FIG. 24, in other embodiments, the battery 174 and the video processor 170 are fixedly attached to the hub 30 and communicate wirelessly to the camera 18 and the monitor 114. For example, in one embodiment, the hub 30, including the video processor 170 and the battery 174, is fixedly attached to the drum 34, and thus rotates with the drum 34 as the cable 14 is spooled and unspooled. This eliminates the need for the slip ring 130. In addition, the wired connection between the hub 30 and the monitor 114 can be replaced with a wireless connection (e.g., Wi-Fi, Bluetooth, etc.) between the video processor 170 and the monitor 114. The hub 30 may contain a wireless communication device 178 for establishing the wireless connection to wirelessly communicate with the monitor 114 and the user interface 270 (if the user interface 270 is a separate unit). The user interface 270 for controlling functions of the camera 18 may be built into the monitor 114 (i.e., a touchscreen or a control panel of the monitor 114), or may communicate wirelessly to the monitor 114 and/or the camera 18. For example, the user interface 270 may be a Wi-Fi enabled smart device that has a software application including a user interface for controlling the camera 18. In some embodiments, the monitor 114 may be an external smart device including the display device 266 and the user interface 270 that may include a touchscreen that acts as both the display screen and the user interface 270. For example, the monitor 114 may include a smart phone, an electronic tablet, a laptop computer, or the like.
