# Quick-Release Battery for Weapon-Mounted Recording Devices > This patent describes a camera designed to attach to a weapon, featuring a battery pack that can be quickly swapped out using a push-button release mechanism. - **Patent:** US 12736314 - **Original title:** Gun mounted recording device with quick release battery - **Granted:** 2026 - **Status:** Active - **Times cited:** 0 - **Field:** consumer_electronics, mechanical, defense, public_safety, telecommunications ## What it does The patent describes a recording device designed to be mounted on a weapon. It consists of two main parts: a "recording unit" and a "power source unit" that can be easily detached. The recording unit contains the camera's core components like a "recording module," "processing device," and "memory." The power source unit, which holds a "battery and memory," attaches to the recording unit using a special "locking mechanism." This mechanism includes a "push button assembly" with a "resilient biasing portion." When the push button is pressed, it moves an "engagement portion" from a locked "engagement position" to a "release position," allowing the power source unit to be quickly removed and replaced. For example, an officer could quickly swap a depleted battery pack for a fresh one without needing tools during an extended shift. ## What it does NOT cover - Does not cover recording devices that are not specifically designed for weapon mounting. - Does not cover battery packs that are permanently fixed to the recording unit or require tools for removal. - Does not cover quick-release mechanisms that do not use a push-button assembly with a resilient biasing portion. - Does not cover recording devices where the battery and recording module are housed together in a single, inseparable unit. ## The clever bit The clever bit is the specific quick-release mechanism for the power source unit, using a push-button assembly with a resilient biasing portion, integrated into a weapon-mounted recording device. This allows for rapid battery changes in demanding environments. ## Real-world examples 1. Weapon-mounted cameras for law enforcement 2. Tactical cameras for military applications 3. Body cameras with quick-swap battery systems 4. Outdoor action cameras designed for rugged use ## Why it matters This technology is important for devices like body cameras or weapon-mounted cameras used by law enforcement or military personnel. The ability to quickly swap batteries means these devices can operate for extended periods without downtime, which is crucial in critical situations. It improves operational efficiency and ensures continuous recording capability when it matters most. ## Frequently asked questions ### What does Quick-Release Battery for Weapon-Mounted Recording Devices cover?
