Anti-Spy Tools
Eight browser tools to check a room, a network or your cameras.
Checking this browser.
| Tool | What it checks | Uses |
|---|---|---|
| Sense the roomUse the device in your hand. | ||
| Ultrasonic Beacons | Listens in the 15 to 24 kHz microphone band for tracking tones from TVs and apps. | Uses the microphone |
| Lens Finder | Hunts the glint a hidden camera lens throws back at your light. | Uses the camera |
| Magnetic Sweep | Watches field strength for anomalies near objects that should hold no electronics. | Uses the magnetometer |
| Identify the deviceName what you found. | ||
| MAC Address Lookup | Names the vendor behind every address in a router list or arp output. | Runs on your device |
| Smart Glasses Guide | Recording lights, cover behaviour and visual tells for camera wearables. | Reference catalogue |
| Check what is exposedPublic flaws and host checks. | ||
| Camera CVE Watch | Exploited flaws in cameras, recorders and footage storage, ranked for patching. | Live from CISA KEV |
| Camera Exposure Probe | RTSP, ONVIF and HTTP handshakes against a public host you own. | Runs from our server |
| Work the roomFollow a repeatable sequence. | ||
| Room Sweep | A checklist that records what you covered, spot by spot. | Saves in this browser |

What this browser can sense
Feature checks only. A rear camera or a working magnetometer is confirmed when a screen asks for permission.
What these tools cannot do
- No radio. RF bugs, GSM listeners, analogue cameras and jammers need a spectrum analyser or SDR.
- No switched-off devices. Finding those takes a non-linear junction detector. Only the lens test sees an unpowered camera.
- No wifi or Bluetooth scan. No web API lists nearby devices.
- No view of your LAN. The camera probe runs from our server and reaches public addresses only.
- A quiet screen is one measurement from one sensor, in one spot, for a few seconds.

How the anti-spy tools work
Sensing tools use your microphone, camera and magnetometer on this device. The MAC lookup runs locally. The camera probe and CVE watch call the pwnsy API.
Radio bugs, wifi scans and switched-off electronics are out of reach of any web API.
How to read this page
"Not on this browser" means a missing API, usually the magnetometer (Chrome and Edge on Android only). Camera flaws come from CISA KEV with FIRST EPSS scores.
Anti-spy FAQ
Can my phone find a hidden camera?
The lens finder hunts the glint a lens throws back, and is the only test here that sees a switched-off camera. A quiet result is one check from one spot.
Can these tools detect bugs that transmit by radio?
No. RF bugs, GSM listeners, analogue cameras and jammers need a spectrum analyser or SDR. Switched-off electronics need a non-linear junction detector.
Can a website scan for wifi or Bluetooth devices nearby?
No web API lists nearby devices. Paste your router's client list into the MAC address lookup instead.
Do my sensor readings leave my device?
No. Sensor readings and the MAC lookup stay in your browser. The camera probe and CVE list call the pwnsy API.
Why does a tool say not on this browser?
The magnetic sweep needs the Magnetometer API (Chrome and Edge on Android). Camera and microphone tools need HTTPS.
Vulnerability data from the CISA KEV catalogue with FIRST EPSS scores, MAC vendor data from the Wireshark manuf mirror of the IEEE registry. Sensor readings are taken in your browser and stay there. API at antispy.pwnsy.com.
