The motion activated recording capabilities of this device are incredibly useful in many scenarios. This feature allows the user to set up the device to start recording only when it senses movement, saving precious storage space and battery life while still capturing important footage. The audio recording capability is also incredibly helpful for providing context or clues as to what's happening on camera or off-camera. Audio recordings can be saved separately from video, so you can choose which one you want to keep and review later without needing both recordings at once.
