How far must a body-worn camera be from an armed ECD for automatic activation?

The correct answer is 30 feet because body-worn cameras (BWCs) are designed to automatically activate when they are within a certain proximity to an Electronic Control Device (ECD), such as a stun gun or Taser. This activation distance ensures that the recording captures critical incidents that may occur when an officer is preparing to deploy an ECD, providing vital evidence for both accountability and transparency.

In this context, 30 feet has been established as the optimal distance to ensure that the camera activates before or upon potential use of the ECD. This distance allows for adequate capture of events leading up to and following the deployment, which is crucial for reviewing the use of force and the circumstances surrounding it. The other distances provided in the options do not align with the specified guidelines established for body-worn camera activation, which emphasizes the importance of accurate and timely documentation of confrontations involving use of force.
