Author: Chief Joseph M. Hallman
WILEAG Standard: 6.1.10
Issue Date: October 31, 2012
Reviewed Date: March 27, 2026
Revised Date: March 27, 2026
Purpose:
The University Police Department has equipped selected vehicles with a digital in-car video/audio recording system and officers with Body Worn Cameras. Together, these units make up the Mobile Audio/Video recording system, or MAV. The MAV is designed to assist and compliment officers in the performance of their duties. The MAV is used to record certain duty related activities, thereby creating a visual and/or audio record of the incident as a supplement to the officer’s report.
The UW-Platteville Police Department has adopted the use MAV devices in order to accomplish the following objectives:
- Accurate documentation of events, actions, conditions, and statements made during arrests and critical incidents so as to enhance officer reports, collection of evidence and testimony in court.
- The enhancement of the Department’s ability to review probable cause for arrest, arrest procedures, officer/suspect interaction, evidence for investigative purposes, as well as officer evaluation and training.
- Protect officers from false allegations of improper police conduct.
- The UW-Platteville Police Department recognizes that cameras can’t always capture everything that is seen by the officer or that happens at a scene, but can act as a tool to help explain an event. Sometimes the cameras are unintentionally obstructed, on a fixed mount, or may not have enough frames per second to capture what the human eye saw or perceived.
It is the purpose of this policy to provide officers with guidelines for the use of MAV recording devices, authorized by this department. This policy shall adhere to the requirements set forth in Wis. Stat.§165.87. This policy is not intended to describe every possible situation where these systems may be used, however, there are many situations where the use of these MAV devices are recommended. (6.1.10)
Policy:
Whenever an officer has time and reason to believe that a contact has an enforcement nature, or believes it is in the best interest of the UW-Platteville Police Department, the contact should be recorded. (An officer shall not jeopardize their safety or the safety of the public in order to activate a camera system).
UW-Platteville Police Officers assigned to a vehicle with a digital in-car video/audio recording system (DICVS) will make every effort to use it to document traffic stops, pursuits, vehicle searches and investigative citizen contacts when occurring within camera range. If reasonable to do so, he/she will record his/her approach to crime scenes and any scene they feel could benefit from being recorded. If practical, the camera will be activated to record infractions, i.e., the justification for traffic stops. Officers may supplement the video recording with an audio description of the event and describe any external factors that may not have been recorded, e.g., prior observations, road conditions, contributing circumstances.
All sworn officers working in a patrol capacity will wear and have turned on a department issued body worn camera at all times unless unavailable or malfunctioning. (6.1.10.2) Training on both body worn and vehicle mounted cameras will be provided to officers during Phase 1 of their Field Training Program. If and when new equipment is purchased, training will be provided to all officers before equipment is implemented for duty use. (6.1.10.8)
Definitions:
- Body Worn Camera- the University Police Department authorizes the use of the Digital Ally FirstVu Pro body camera as its primary body worn camera system.
- DICVS- digital in-car video/audio recording system. Digital Ally EVO is the DICVS installed in UW-Platteville Police Department primary squads.
- Pre-Event Recording- the DICVS system will retain the video recording made prior to a trigger event, up to 60 seconds, depending on system settings. Audio is not recorded until the trigger event occurs.
- Recorded Media- refers to audio-video signals recorded on any of several storage devices, including analog tape (VHS, SVHS, Hi 8mm), digital tape (DV), or other portable digital storage devices (CD, DVD, hard drive, flash memory, etc.).
- Trigger Event- an event that causes the DICVS to begin saving video/audio recordings. Events include activation of the following: emergency lights/siren, vehicle speed exceeds preset threshold setting, and manual activation of the DICVS system. The recording ends when the officer presses the stop button, and the trigger event is no longer active.
- Video Camera- digital video camera with on-screen menu controls.
- Wireless Microphone- the wireless microphone's audio channel for the DICVS is integrated with the body worn camera, providing both audio for the body worn camera video and for the DICVS system.
