A communication transmitted from Yi-An Huang, City Manager, relative to a Surveillance Technology Impact Report which describes Body Worn Camera technology, requested by the Police Department

SURVEILLANCE TECHNOLOGY IMPACT REPORT Department: Police Division or Unit (if applicable): Procedural Justice, Crime Analysis, Professional Standards and/or potentially a new unit Submitted by: Commissioner Christine Elow Date: 12/05/2023 Surveillance Technology: Body Worn Camera 1. Describe how the proposed Surveillance Technology will work, including how it will collect Surveillance Data. • The technology is body worn cameras (“BWC”) coupled with a digital evidence management system that will store the video and audio and provide tools to manage all recordings. This will be a cloud-based solution, that is Criminal Justice Information Services (CJIS) compliant. • Body worn cameras will capture audio and video recordings of all police enforcement actions and possible enforcement encounters. • The digital evidence management system will provide the ability for tagging and redacting copies of the video and audio recordings. The digital evidence management system will also provide export capabilities to the Cambridge Police Department’s Record Management System which is the central repository for tracking all evidence. • The BWC can be activated manually by an officer and will be activated automatically in the event an officer removes their firearm from its holster, which will prompt a magnetic device that cues the BWC to start recording. • Officers will be required to download the data from their BWC for each working shift. This data will be uploaded to a cloud based digital evidence management system. • CPD will maintain the data and restrict access to such as required by the CJIS security policy. 2. What is the purpose of the Surveillance Technology? • The purpose of body worn cameras is to record enforcement, investigative and other encounters between the police and the public. BWC provide a contemporaneous, objective record of these encounters, facilitate review of events by supervisors, foster

accountability, and encourage lawful and respectful interactions between the public and the police. The use of body worn cameras has shown that cameras may help de-escalate potentially volatile encounters. BWC may also provide important evidence in criminal and civil proceedings as well as resolving citizen complaints. Additionally, BWC will aid in transparency and accountability to the public in the following areas: o Documenting and improving performance of City employees o Police interactions with the public o Gathering evidence of violations of any law in criminal, civil, and administrative actions o Identifying and preventing threats to persons and property and preventing injury to persons or significant damage to property o Identifying, apprehending, and prosecuting criminal offenders o Maintaining the safety and security of City employees, students, customers, and City-owned or controlled buildings 3. Where will the Surveillance Technology be deployed? When? • Throughout the City. • The technology would be deployed on all shifts by all officers unless the officer is assigned to the station in an administrative capacity. • Anticipated deployment of Body Worn Cameras is early 2024 depending on procurement of the hardware, software, and training officers on the new technology. 4. What privacy impact will the Surveillance Technology have? • Body worn cameras will capture audio and video of police enforcement or possible enforcement encounters with the public. Data from audio and video recordings captured on body worn cameras will be stored for a minimum thirty-seven (37) months and as otherwise required by municipal records retention schedule. • The digital evidence management system will provide the capability for redaction of audio and video records that are subject to public record requests, as appropriate. The redaction will be of similar content as is in place today for similar public records requests. • Criminal Justice Information Services (CJIS) Security Policy will be used to ensure the privacy and security of this data. The data protection safeguards will include ensuring the cameras and the digital evidence platform are CJIS compliant, establishing an audit trail and chain of custody, customized user permissions, and data encryption. The data will be

stored off site in a CJIS compliant manner by the vendor that provides the body worn camera technology. The Cambridge Police Department will maintain control and ownership of this technology and the data it captures. • This data may be shared with the Middlesex County District Attorney’s Office and law enforcement agencies as required by law. This data is also subject to FOIA requests. 5. What are the fiscal costs of the Surveillance Technology, including initial costs, ongoing maintenance and personnel costs, and source of funds? • The source of the funding will be a combination of Free Cash Appropriation, Capital, and Operating funds. • The cost for the vendor services for five years providing 300 cameras is estimated in the range of 1.6M to 2.3M dollars. The estimated first year costs range from 600K to 800K. The following years are estimated at 500K. This includes maintenance costs. These cost estimates were derived from budgetary quotes provided from two vendors. • There will be additional costs comprised of: o Administrative costs incurred by CPD for training, FOIA requests, and providing evidence to court. o Additional costs for a new unit for redacting, monitoring, and reviewing data collected on a day-to-day basis. This is estimated to be four to seven full-time employees. The team will be comprised of sworn and non-sworn employees, for which there will be a need to add three new non-sworn full-time employees. o IT and Electrical infrastructure costs for: power, cabling, networking, servers, application integration, and project management.
