Abstract: Disclosed herein are systems, apparatuses, devices, and methods for surveillance. In at least some embodiments, a surveillance unit is disclosed that is configured to function as a stand-alone detection and/or surveillance unit; that is, it functions without a network or external power. The surveillance unit may be configured to detect and/or surveil vehicles, including vehicles without license plates (e.g., motorcycles or motorbikes without license plates displayed in the front of the motorcycle or motorbike, respectively.
