Flock-You Detection Project: Complete Counter-Surveillance Hardware and Setup Guide 2026

Complete Technical Guide to Building and Using Flock-You Detection Devices

Introduction: Open Source Counter-Surveillance

The Flock-You project represents a groundbreaking development in privacy technology—an open-source, community-driven initiative to detect and map Flock Safety’s ALPR surveillance infrastructure. Hosted on GitHub at colonelpanichacks/flock-you, this project leverages affordable ESP32-based hardware to identify Flock cameras through their WiFi network signatures.

This comprehensive guide covers everything from the technical methodology behind Flock detection to step-by-step setup instructions for three hardware platforms, firmware installation, and purchasing information from authorized vendors. Whether you’re a privacy advocate, security researcher, or concerned citizen, this guide will enable you to build or purchase your own detection device.

For context on why this technology matters and the broader surveillance landscape, read our companion article: Flock Safety Camera Surveillance: Prevalence, Privacy Concerns, and Protection Strategies .

Understanding the Flock-You Detection Methodology

The Technical Foundation

Flock Safety cameras contain embedded WiFi modules for connectivity and remote management. These modules broadcast identifiable network signatures that can be detected by devices operating in promiscuous WiFi monitoring mode. The Flock-You project exploits this characteristic through:

1. WiFi OUI (Organizationally Unique Identifier) Detection

Every network interface has a MAC address consisting of:

First 3 bytes (24 bits): OUI - identifies the manufacturer
Last 3 bytes: Device-specific identifier

Researchers @NitekryDPaul and the DeFlockJoplin community discovered 31 specific OUIs consistently present in Flock Safety camera deployments:

Primary Espressif OUIs (ESP32-based modules):
D4:AD:FC - Espressif Inc. (Common ESP32-S3)
AC:67:B2 - Espressif Inc. (ESP32-WROOM)
84:F3:EB - Espressif Inc. (ESP32-S3 variants)
B4:E6:2D - Espressif Inc. (ESP32-C3)
CC:DB:A7 - Espressif Inc. (ESP32-based)
24:0A:C4 - Espressif Inc. (ESP32-SOLO)
30:AE:A4 - Espressif Inc. (ESP32-WROVER)
94:B9:7E - Espressif Inc. (ESP32-based)
A4:CF:12 - Espressif Inc. (ESP32-S2)
C0:49:EF - Espressif Inc. (ESP32-C6)

Additional OUIs identified in Flock deployments:
[... 21 additional manufacturer OUIs ...]

When a detection device scans WiFi traffic in promiscuous mode, it can identify any device broadcasting frames with these OUIs.

2. Wildcard Probe Request Detection

Flock cameras periodically send wildcard probe requests searching for available networks. These have distinctive characteristics:

802.11 Management Frame: Type=0, Subtype=4
SSID Information Element: Length=0 (empty/wildcard)
Frame structure: Predictable pattern in probe timing
Vendor-specific IEs: Additional indicators in frame payload

Detection firmware analyzes these probe request patterns to increase confidence in Flock camera identification beyond simple OUI matching.

3. Promiscuous Mode WiFi Monitoring

Standard WiFi operation only receives frames addressed to your device. Promiscuous mode captures all WiFi frames within range:

802.11 frame structure: Analyzing addr1, addr2, addr3 fields
Management frames: Probe requests, beacon frames, association requests
Data frames: Can reveal network behavior patterns
Control frames: ACKs, RTSs, CTSs provide timing information

ESP32 microcontrollers support promiscuous mode through the esp_wifi API, enabling low-cost detection hardware.

4. Signal Strength Analysis

Detection devices measure RSSI (Received Signal Strength Indicator) to:

Estimate distance to detected cameras
Triangulate locations with multiple measurements
Filter false positives based on expected signal characteristics
Create heat maps of camera density

Detection Accuracy and False Positives

The Flock-You methodology achieves high accuracy:

True Positive Rate: ~95% for confirmed Flock cameras in range
False Positive Rate: ~5-10% depending on environment
Detection Range: 50-300 feet depending on obstacles and antenna
Confidence Scoring: Multi-factor analysis reduces false alarms

Common False Positive Sources:

ESP32 development boards used in other IoT devices
Commercial ESP32-based products (smart home, sensors)
Other surveillance cameras using similar components
WiFi testing equipment operated by technicians

Mitigation Strategies:

Multi-signature detection: Combining OUI + probe pattern + physical verification
Location correlation: Cross-referencing with known camera locations
Visual confirmation: Physical inspection after electronic detection
Community database: Crowdsourced validation of detections

Technical Deep Dive: Understanding the Code

Core Detection Algorithm (Simplified)

For those interested in the technical implementation, here’s a simplified view of the detection logic:

// Flock-You Detection Core (Conceptual - not full code)

// OUI Database (31 known Flock-associated OUIs)
const uint8_t FLOCK_OUI_LIST[][3] = {
    {0xD4, 0xAD, 0xFC}, // Espressif ESP32-S3
    {0xAC, 0x67, 0xB2}, // Espressif ESP32-WROOM
    {0x84, 0xF3, 0xEB}, // Espressif ESP32-S3 variant
    // ... 28 more OUIs ...
};

// Promiscuous mode callback
void wifi_sniffer_callback(void* buf, wifi_promiscuous_pkt_type_t type) {
    wifi_promiscuous_pkt_t *pkt = (wifi_promiscuous_pkt_t*)buf;
    
    // Extract MAC address from frame
    uint8_t *mac = pkt->payload + 10; // addr2 field position
    
    // Check against OUI database
    for (int i = 0; i < NUM_OUIS; i++) {
        if (memcmp(mac, FLOCK_OUI_LIST[i], 3) == 0) {
            // OUI match found
            int rssi = pkt->rx_ctrl.rssi;
            
            // Check signal strength threshold
            if (rssi > RSSI_THRESHOLD) {
                // Analyze frame for additional signatures
                if (is_wildcard_probe_request(pkt)) {
                    // High confidence detection
                    trigger_alert(mac, rssi, HIGH_CONFIDENCE);
                } else {
                    // OUI match only
                    trigger_alert(mac, rssi, MEDIUM_CONFIDENCE);
                }
            }
        }
    }
}

// Wildcard probe detection
bool is_wildcard_probe_request(wifi_promiscuous_pkt_t *pkt) {
    // Management frame, subtype probe request
    if ((pkt->payload[0] & 0x0F) != 0x04) return false;
    
    // Check for empty SSID IE (wildcard)
    // Position depends on frame structure
    uint8_t *ie = &pkt->payload[24]; // Start of IEs
    if (ie[0] == 0x00 && ie[1] == 0x00) {
        return true; // Wildcard probe
    }
    return false;
}

Key Technical Concepts Explained

Promiscuous Mode: Instead of only receiving frames addressed to your device, ESP32 captures all WiFi frames in range. This is essential for detecting nearby devices that aren’t communicating with your detector.

MAC Address Structure: Every WiFi frame contains multiple MAC addresses:

addr1: Receiver address
addr2: Transmitter address (contains OUI)
addr3: Address of final destination/source

RSSI (Received Signal Strength Indicator): Signal strength in dBm (negative decibels relative to 1 milliwatt). Typical values:

-30 dBm: Extremely strong (very close)
-50 dBm: Strong signal
-70 dBm: Weak but usable
-90 dBm: Very weak (edge of range)

Probe Requests: WiFi devices send probe requests to discover available networks. Wildcard probes (empty SSID) search for any network, which is common in IoT devices like Flock cameras.

Troubleshooting Common Issues

Problem: No Detections Despite Known Camera Nearby

Possible Causes:

Camera offline/powered off: Flock cameras may be temporarily inactive
Signal blocked: Building materials absorb WiFi (metal, concrete)
Out of range: Effective range ~100-300 feet depending on obstacles
Firmware issue: Outdated firmware may miss newer OUI variants

Solutions:

Confirm camera is visible and appears operational (solar panels, lights)
Move closer to suspected camera location
Try different antenna orientations
Update to latest Flock-You firmware
Check device is actually scanning (verify LED/display activity)

Problem: Excessive False Positives

Possible Causes:

High density of ESP32 devices: Smart home, IoT devices common
Sensitivity too high: Detecting distant/irrelevant devices
Other surveillance cameras: Many use ESP32 modules

Solutions:

Reduce sensitivity setting
Enable wildcard probe detection (higher confidence)
Physically verify detections before logging
Use signal strength to filter (only alert on strong signals)
Update OUI database to focus on confirmed Flock OUIs

Problem: Battery Drains Quickly

Possible Causes:

Continuous scanning: No sleep/power management
Display always on: Screen consumes significant power
GPS active: GPS modules power-hungry
Old battery: Li-Po batteries degrade over time

Solutions:

Enable passive scan mode (intermittent vs. continuous)
Set display timeout
Disable GPS when mapping not needed
Replace battery (OUI-SPY/mesh-detect v2 have replaceable batteries)
Use external battery pack for extended sessions

Problem: GPS Not Acquiring Lock

Possible Causes:

Indoor use: GPS requires sky visibility
Antenna not connected: mesh-detect v2 needs external antenna connected
Cold start: First GPS lock can take 5-15 minutes
Interference: Nearby electronics can interfere

Solutions:

Move to position with clear sky view
Ensure antenna properly connected (SMA connector)
Wait patiently for initial lock (subsequent locks faster)
Move away from RF interference sources
Check GPS is enabled in settings

Problem: Data Not Logging to SD Card

Possible Causes:

SD card not formatted: Must be FAT32 format
SD card full: No space remaining
Card not detected: Not fully inserted
File system corruption: Card damaged

Solutions:

Format SD card as FAT32 (32GB maximum for compatibility)
Delete old logs or use larger card
Reinsert card fully (should click)
Reformatformat card or replace if damaged
Check device recognizes card (menu will show SD status)

Legal and Ethical Considerations

Legal Status of Detection Devices

WiFi Scanning Legality:

✅ Legal in US: Passive WiFi monitoring (receive-only) is legal
✅ No interception: Devices only monitor publicly broadcast frames
✅ No decryption: Not attempting to decrypt data or connect to networks
✅ Similar to radio scanners: Comparable legal status to police scanners

Important Distinctions:

❌ Illegal: Active jamming/interference with camera operation
❌ Illegal: Attempting to hack or access camera systems
❌ Illegal: Destroying or tampering with physical cameras
⚠️ Gray area: Some jurisdictions have stricter privacy laws

Recommendation: Detection devices are for awareness only. Do not interfere with camera operation.

Ethical Usage Guidelines

Responsible Use:

✅ Use for personal awareness of surveillance
✅ Document for advocacy and policy discussions
✅ Share aggregated data with privacy organizations
✅ Contribute to community mapping projects
✅ Educate others about surveillance infrastructure

Avoid:

❌ Using data to facilitate illegal activities
