What frequency range do your sensors cover?

The 24/7 sensor continuously monitors WiFi 2.4 GHz (channels 1-13) and Bluetooth/BLE bands. During on-site sweeps, our equipment covers the full spectrum from 1 MHz to 10 GHz, including HF, VHF, UHF, and SHF bands.

How do you identify devices on my network?

Our gateway passively monitors DHCP, mDNS, NetBIOS, SSDP, and LLMNR network traffic to identify all devices. Each device is automatically categorized using OUI vendor lookup, Fingerbank API, and BLE manufacturer data. MAC address rotation is detected and devices are grouped by physical identity.

Do you detect BLE tracker MAC address rotation?

Yes. Modern BLE devices like phones rotate their MAC addresses for privacy. Our system detects this rotation and correlates devices by manufacturer data, advertisement patterns, and signal characteristics to group them as a single physical device.

📡

RF Spectrum Analysis

Wideband spectrum monitoring from 1 MHz to 10 GHz during on-site sweeps. The 24/7 sensor covers 2.4 GHz WiFi (channels 1-13) and Bluetooth/BLE bands continuously.

📶

Wireless Network Audit

The sensor passively monitors all 13 WiFi channels and detects every access point, connected device, and probe request. It flags hidden networks, deauth attacks, and rogue access points.

🔍

Tracking Device Detection

Identification of covert GPS trackers, Bluetooth beacons, AirTags, SmartTags, and other location tracking devices operating in your environment or on your vehicles.

🛡️

Network Discovery

Identification of all devices on your local network, detection of open ports and services, unauthorized access points, and suspicious network activity.

⚡

Real-Time Monitoring

Our sensor monitors 24/7 and sends alerts when new or suspicious devices appear. You access the dashboard from your phone or computer.

📊

Detailed Reporting

Each detected device is logged with signal strength, first/last seen time, and threat classification. Reports available on demand.

🔌

Passive LAN Discovery

The gateway passively sniffs DHCP, mDNS, NetBIOS, SSDP, and LLMNR traffic to identify all devices on your local network — including wired and bridged devices behind routers.

🏷️

Automatic Device Categorization

Every detected device is automatically classified (phone, computer, IoT, camera, media, NAS, sensor) using OUI vendor lookup, Fingerbank API, and BLE manufacturer data. MAC address rotation is detected and devices are grouped by physical identity.
