EMF Reader & Scanner - Ferrix

Ferrix is an EMF reader for magnetic fields: a magnetic field detector, a wall scanner for iron and steel, and a guided check for hidden cameras, plus a WiFi camera detector for the network you are on. It reads the magnetometer inside your phone, shows the field in microtesla or milligauss and explains in plain words what the number means.

MAGNETIC FIELD METER

• Live value in µT or mG with a clear rating, from "calm" to "strong source"

• Set zero where nothing is around, then see only the change (Pro)

• Search tone that rises with the field change (Pro)

• A simple detector for iron and steel nearby and an EMF reader for fields of devices, magnets and cables under load

WALL SCANNER

Lay the phone flat on the wall and slide it slowly sideways. A beep marks a clear change in the magnetic field near the surface, and Ferrix numbers each spot. That can be iron or steel such as screws, nails or steel profiles, or a cable under load, so it can help as a stud finder where screws hold the board. Wood, plastic and copper without current stay invisible and small or deep objects can be missed: a wall without a spot is no proof that it is safe to drill. Share your wall scan as an image.

HIDDEN CAMERA CHECK

A guided walk through nine places where hidden cameras can sit: smoke detectors, chargers and USB plugs, clocks, TV and router, pictures and mirrors, air vents, decor, bed and lamps, bathroom.

• Lens finder: Ferrix blinks the flash and circles only small dots that light up with it again and again, because a camera lens can throw light back.

• IR view: some front cameras show night vision LEDs your eyes cannot see; a TV remote test shows whether yours does.

• Magnet: a strong reading on an object can point to a magnet or electronics inside, but proves nothing alone.

Mark each place as "nothing seen" or "look closer", saved per room.

WIFI NETWORK SCAN

Ferrix checks the Wi-Fi you are on for devices that act like a camera: a reply on the stream ports 554 or 8554 (RTSP), an ONVIF or UPnP announcement with maker and model, a web server name pointing to a camera, or ports typical for video recorders. Each marked device shows why. If the Wi-Fi keeps devices apart, Ferrix says so: then no network scan can tell anything. A camera without Wi-Fi, in another network or recording only to an SD card is invisible to any network scan.

WHAT YOU GET FOR FREE

• Live value in µT or mG with a rating

• 1 wall scan with result and share image (up to 3 tries if nothing is marked)

• 1 short lens scan (15 flash cycles) and 1 IR session (30 seconds), once each

• 1 room with 3 of the 9 places

• 1 network scan with the full result

FERRIX PRO

• Lens finder and IR view without limits, for every hotel room, rental or changing room

• All 9 places in every room, plus the room report as one image to share

• Network scans without limits, "new since the last scan in this network" and the result in the room report

• Unlimited wall scans, each stays open in the history

• Zero point, search tone, trace of the last 30 seconds, peak hold and all 3 axes

Pro gives you more time and more places, not certainty: even there a dot is only a hint and no dot is no proof. Pro is a monthly or yearly subscription.

HONEST ABOUT WHAT IT MEASURES

The magnetometer sees static and low-frequency magnetic fields from iron, steel, magnets, coils and cables under load. It does not measure radio waves such as Wi-Fi or 5G, and Ferrix makes no health claims. No app can promise to find every hidden camera: a camera that is switched off and hidden behind a wall stays hidden. Ferrix shows you where to look closer. It is not a safety or medical device.

PRIVATE

No account and no ads. Camera images for lens finder and IR view stay in memory and are never saved or sent. The network scan stays inside the Wi-Fi you are on. Your scans stay on your phone. Anonymous usage counts (such as Pro page views) carry no device or advertising ID.
