FlockU Alert

Standalone, offline-first awareness of mapped Flock ALPR cameras and roadside surveillance infrastructure

FlockU Alert is a dedicated GPS/GNSS-based camera awareness device for drivers who want to know when mapped Flock ALPR cameras may be nearby.

The device continuously compares its current location against a nationwide onboard database of publicly mapped Flock camera locations. When you approach a known location, FlockU Alert provides screen and LED proximity warnings before you reach the camera.

No phone app, account, subscription, or live internet connection is required during normal use. Location checks happen locally on the device.

Built on the Heltec Wireless Tracker platform and shipped in a 3D-printed, vehicle-mountable enclosure, FlockU Alert is designed for privacy-conscious drivers, journalists, researchers, activists, delivery drivers, civic-tech users, and anyone who wants practical roadside-surveillance awareness without relying on cloud services.

Why GPS and mapped camera data?

Some camera-detection projects attempt to identify ALPR systems by listening for nearby Wi-Fi, Bluetooth, MAC addresses, or manufacturer OUIs.

That approach can be useful for research, but it may not provide much advance notice while driving. By the time a short-range wireless identifier is detected, your vehicle may already be within the camera’s field of view.

FlockU Alert takes a different approach.

Instead of asking:

“Can I hear the camera right now?”

FlockU Alert asks:

“Am I approaching a location where a Flock camera has already been mapped?”

By comparing your GPS/GNSS position against a local camera database, the device can provide useful proximity awareness before you are directly beside a known camera.

Advantages of location-based awareness

• Alerts are based on mapped camera locations rather than short-range wireless broadcasts
• Can provide warning before you are directly beside the camera
• Does not depend on Wi-Fi, Bluetooth, MAC address, or OUI visibility
• Remains useful when camera hardware is silent, shielded, reconfigured, or not broadcasting
• Designed for use while driving and moving through an area
• Requires no phone, app, account, subscription, or internet connection during normal use
• Keeps location checks local on the device

Nationwide onboard camera database

FlockU Alert ships with a preloaded nationwide dataset covering all 50 U.S. states and Washington, DC.

The device uses its GPS/GNSS position to determine which state you are currently in, then loads the appropriate camera-location pack from its internal storage.

Included camera data

• Nationwide U.S. Flock camera dataset
• Coverage for all 50 states and Washington, DC
• State-specific camera packs stored locally in LittleFS
• Built from publicly available and community-maintained camera-location data
• Camera database can be refreshed through filesystem updates
• No cloud lookup required during normal operation

All camera-location checks are performed directly on the device.

Camera coverage will vary by location. Public datasets may contain missing, outdated, duplicated, or incorrectly mapped entries. FlockU Alert will not identify every Flock camera, ALPR system, or roadside surveillance device.

It should be treated as an awareness tool, not a complete or authoritative surveillance map.

LED proximity alerts

The onboard LEDs provide a fast, at-a-glance indication that a mapped Flock camera is ahead.

At approximately 1,000 feet and closing, the LEDs begin illuminating progressively as the device gets closer to the mapped location.

This allows you to receive a visual warning without needing to continuously watch the screen.

The display also shows proximity information when a mapped camera location is nearby.

Battery backup helps preserve GPS lock

FlockU Alert includes a small 400mAh internal battery.

The battery is not intended to provide extended standalone runtime. Its primary purpose is to keep the device and GPS/GNSS receiver active during short vehicle stops.

This can help preserve an existing satellite lock while:

• Running errands
• Making deliveries
• Stopping briefly along a route
• Turning the vehicle off for a short period
• Using an ignition-switched USB outlet

Many vehicles include either:

• Always-on USB power, which remains active while the vehicle is off
• Ignition-switched USB power, which shuts off when the vehicle is turned off

When ignition-switched power is used, the battery can keep the device operating for roughly an hour, depending on conditions and battery state. This helps the device resume alerts quickly without waiting for a completely new GPS fix.

Vehicle-ready mounting

Each FlockU Alert includes a vehicle-mountable enclosure designed to keep the screen and LEDs visible while driving.

Included mounting components:

• 3D-printed device enclosure
• 3D-printed enclosure back
• Integrated 1-inch RAM-compatible ball interface

A RAM arm, vehicle base, suction mount, or other external RAM mounting hardware is not included unless specifically stated in the order.

Designed as a dedicated appliance

FlockU Alert is not a general-purpose hacking tool and it is not a phone app placed inside a plastic enclosure.

It is a purpose-built appliance designed to perform one job:

Provide local awareness of mapped Flock ALPR camera locations.

The compact display provides proximity information, the LEDs deliver an immediate visual warning, the internal battery helps maintain GPS lock during short stops, and the RAM-compatible enclosure makes the device practical for vehicle use.

Who it is for

FlockU Alert is designed for people who want greater visibility into roadside surveillance and public camera infrastructure.

Potential users include:

• Privacy-conscious drivers
• Delivery drivers and gig workers
• Journalists and documentarians
• Activists and community observers
• Civic-technology researchers
• Security and privacy researchers
• Radio and hardware hobbyists
• People who prefer offline, single-purpose devices
• Anyone interested in understanding the surveillance infrastructure around them

What is included

• Heltec Wireless Tracker-based FlockU Alert device
• Preloaded FlockU firmware
• Preloaded nationwide U.S. camera database
• Coverage for all 50 states and Washington, DC
• 3D-printed enclosure with 1-inch RAM-compatible ball
• 400mAh battery backup

Important limitations

FlockU Alert depends on publicly available and community-maintained camera-location data.

Camera coverage may be incomplete, outdated, duplicated, incorrectly mapped, or unavailable in some areas. Cameras may also be moved, removed, installed, or replaced without being immediately reflected in the database.

FlockU Alert:

• Will not detect every Flock camera
• Will not detect every ALPR system
• Will not detect every roadside camera
• Does not confirm whether a mapped camera is currently operational
• Does not prevent a vehicle or license plate from being photographed
• Should not be relied upon as a safety, navigation, or law-enforcement avoidance system

The internal battery is intended for short ignition-off periods and GPS-lock preservation. It is not intended for all-day operation without USB power.

Lawful and ethical use

FlockU Alert is designed for civic awareness, privacy education, research, documentation, and public-interest monitoring.

Do not use this device to:

• Commit or flee a crime
• Evade lawful detention or investigation
• Vandalize, disable, or tamper with cameras
• Interfere with public or private infrastructure
• Trespass on restricted property
• Harass workers, agencies, businesses, or property owners

Use responsibly and in accordance with applicable laws.
