The Multi-Unit Charger is a product that integrates fast charging and high-speed data acquisition, allowing it to charge the body camera and additional batteries simultaneously. Moreover, when the MultiUnit Charger is connected to a computer with the integrated docking software, it automatically acquires evidence from the body camera. During this process, the system protects all data using a HASH algorithm to keep the integrity of the evidence, ensuring that the data cannot be accessed or extracted through any other devices or software.
