TASER International, maker of body-worn cameras, has announced its new Signal Performance Power Magazine. The SPPM is a smart battery that works with TASER's X2 and X26P Smart Weapons. It is designed to automatically inform Axon Fleet compatible cameras that a TASER Smart Weapon within signal range is armed, when the trigger is pulled, or when its arc switch is activated. The cameras can sense the Smart Weapon status change and start recording.
