Where Public Safety Meets Personal Privacy
How the Douglas County Sheriff’s Office uses Technology to prevent, detect, and solve crimes while protecting our citizens’ privacy.
The Douglas County Sheriff’s Office uses advanced technology, including automated license plate reader (ALPR) cameras, to help prevent, detect, and solve crime across the county. These cameras capture license plates and limited vehicle characteristics—such as make, color, and distinguishing features—providing deputies with timely, objective data to identify vehicles associated with criminal activity, even when plates are missing, altered, or switched.
ALPR data is securely processed through vetted law enforcement systems and retained for a limited period in accordance with established policies and applicable laws. Access to this information is restricted to authorized personnel for legitimate law enforcement purposes, and all use is subject to audit and oversight.
This technology serves as a force multiplier for public safety while maintaining a strong commitment to privacy and civil liberties. The Douglas County Sheriff’s Office employs ALPR systems under strict guidelines that emphasize responsible use, data security, transparency, and constitutional protections.
Key safeguards include:
- Data may only be accessed for legitimate law enforcement purposes;
- All system use is logged and may be subject to audit;
- Data is automatically deleted after 30 days unless it becomes criminal evidence; and
- ALPR specifically cannot track individuals or capture personal identifiers.
How ALPR Data is Captured and Stored.
Our ALPR cameras capture vehicle information as they pass through the designated areas. The captured information is then stored securely with our cloud vendor, allowing authorized users to search the data, receive alerts, and stay on top of current incidents.
01 : Vehicle Capture
The cameras are designed to capture an image that is directly focused on the lanes of traffic at the license plate level. This method deliberately avoids capturing unnecessary personal details and people.
02 : License Plate Recognition
The cameras use advanced computer vision & license plate recognition (LPR) technology to analyze the images they capture. During this process, key items are identified, such as vehicle characteristics (color, make, model, etc), and the license plate is accurately read. This creates a comprehensive searchable database to serve as a powerful tool to assist in fighting crime.
03 : Secure Cloud Storage
The images and vehicle characteristics are encrypted and securely stored within our cloud vendor's platform. Our vendor has undergone rigorous security and compliance testing, including CJIS, SOC 2, ISO/IEC, and NIS 2.
04 : Alerts & Searches
Authorized personnel can search the gathered data using the license plate number or vehicle characteristics. They also have the ability to setup alerts based on the vehicle characteristics (ex. stolen vehicle).
05 : Data Retention
Captured data is retained for a certain period of time based on the Sheriff's Office retention policy.
Other Technologies
Automated License Plate Reader (ALPR)
ALPR is used to help prevent, detect, and solve crime across the county. These cameras capture license plates and limited vehicle characteristics—such as make, color, and distinguishing features—providing deputies with timely, objective data to identify vehicles associated with criminal activity, even when plates are missing, altered, or switched.
Drones
The Sheriff's Office currently uses drones at emergency scenes and wildfires to provide real-time situational awareness (4K video/thermal imaging) before and after ground units arrive. This technology improves public safety by aiding search-and-rescue and fire assessment and by reducing risky police encounters.
Body Worn Cameras
A body camera is a wearable audio, video, or photographic recording device used primarily by law enforcement to record daily routines and interactions with the public. These small, chest-mounted devices improve accountability, provide evidence, and enhance transparency by capturing interactions from an officer's perspective.
Online Reporting
The Sheriff's Office utilizes an online reporting system to assist with minor offenses and when a Deputy is not required to be on scene immediately. Report data is stored in accordance with all law enforcement standards.
Artificial Intelligence (AI)
The Sheriff's Office currently utilizes AI in a variety of ways to assist with reporting writing, daily office procedures, and within our online reporting system. The AI programs or agents must be vetted by the office's Technology Services unit to ensure compliance with CJIS, HIPAA, and other law enforcement standards.
