Canadian YouTuber Builds ALPR Camera to Track Police Vehicles

The Project That Turned Heads

Anthony Sistilli, a Toronto‑based YouTuber known for his DIY tech videos, unveiled a camera system that can read license plates and automatically follow police vehicles. The device, which he describes as a "Flock‑like" setup, captures plate numbers, matches them against a list of known police identifiers and then steers a motorized mount to keep the target in frame.

From Hobbyist to Controversy

What began as a curiosity about automatic number‑plate recognition (ANPR) quickly escalated when local police approached Sistilli for questioning. According to the creator, officers were concerned that the system could be used to monitor police movements, a scenario that raised eyebrows across the tech community.

How the Camera Works

The system combines off‑the‑shelf components with open‑source software. A high‑resolution webcam captures video, while a Raspberry Pi processes each frame with an ALPR library. When the software detects a plate that matches a pre‑loaded database of police numbers, it triggers a servo‑controlled gimbal to keep the vehicle centered.

Hardware and Software Choices

• Camera: 1080p USB webcam with low‑light capability.
• Processor: Raspberry Pi 4, chosen for its balance of power and cost.
• Software: OpenALPR, an open‑source library that converts images to text.
• Mount: 3‑axis gimbal controlled by Python scripts.

This combination allows the device to operate for several hours on a portable battery pack, making it suitable for street‑level testing.

Tracking Police Vehicles Specifically

Sistilli programmed the system to recognize a handful of plate patterns used by Ontario’s police forces. When a match occurs, the camera logs the timestamp, GPS coordinates and a short video clip. The data is stored locally and can be uploaded to a private server for analysis.

Legal and Privacy Implications

Canada’s privacy framework places strict limits on the collection of personal information by private entities. The Office of the Privacy Commissioner notes that surveillance tools that capture identifiable data must have a clear, lawful purpose.

Canadian Privacy Law Perspective

Under the Personal Information Protection and Electronic Documents Act (PIPEDA), gathering license‑plate data without consent could be considered a breach, especially if the information is used to track individuals or law‑enforcement activities. Critics argue that Sistilli’s project skirts the line between legitimate research and unlawful monitoring.

International Examples of ALPR Misuse

Studies from the United Kingdom and the United States have shown that widespread ALPR deployment can create detailed movement profiles of citizens. A University of Toronto research paper highlighted how long‑term plate collection can reveal patterns of daily life, raising concerns about function creep.

Community Reaction and Online Debate

The video of the camera in action sparked a flood of comments across social media platforms. Some viewers praised the technical ingenuity, while others warned of a slippery slope toward mass surveillance.

Supporters Praise Transparency

Proponents argue that exposing police routes can increase accountability. They point to cases where independent monitoring helped uncover misuse of force or unlawful stops. By making the data publicly available, they claim, citizens gain a tool to hold authorities accountable.

Critics Warn of Surveillance Overreach

Privacy advocates stress that the same technology could be turned against ordinary drivers, creating a de‑facto panopticon. They cite the National Institute of Standards and Technology guidelines on biometric and location data, which recommend strict controls to prevent abuse.

What This Means for Future Tech Projects

Sistilli’s case illustrates a broader tension between maker culture and regulatory frameworks. As hobbyists gain access to powerful sensors and AI‑driven software, the line between experimentation and infringement becomes blurred.

Key takeaways for creators include:

1. Research local privacy statutes before launching a project that records personal data.
2. Consider implementing data minimisation, such as deleting footage after a short retention period.
3. Engage with legal counsel or privacy experts when the technology could intersect with law‑enforcement activities.
4. Be transparent about data collection methods and intended use.

By following these guidelines, innovators can enjoy the creative freedom of the maker movement while respecting the rights of individuals and institutions.

As the conversation around ALPR technology continues, the Canadian case may serve as a reference point for how societies balance transparency, security and privacy in an era of ubiquitous cameras.
