Abstract

Systems, apparatuses, and techniques for video delivery can include one or more of the following: a wireless camera arranged in a wearable form factor comprising a battery to provide energy, and configured to generate a video feed, and a base station in wireless communication with the wireless camera and configured to receive the video feed from the wireless camera and process the video feed, and a video portal device communicatively coupled with the base station and configured to receive the processed video feed from the base station and deliver at least a portion of the processed video feed to one or more remote clients. A base station can reserve a wireless channel for the wireless camera for a video transmission.
