Hidden camera detector in your pocket.
Walk into an Airbnb, hotel, or rental and check for IP cameras, microphones, and tracking devices in under two minutes — using just your phone.
Airbnbs & rentals
Sweep before you unpack. 1 in 10 short-term rental guests have reported finding a camera.
Hotel rooms
Check the smoke detector, the alarm clock, the vent above the bed. Two minutes of peace of mind.
Rental cars
GPS trackers and dash cams aren't always disclosed. The magnetometer can flag magnetic anomalies that hint at electronics behind the dash.
Your own home
After a break-up, a move-in, or a stalking situation. Know exactly what's on your network.
Surface the networked cameras hiding in plain sight.
Spyzero scans the local subnet in about 10–30 seconds, fingerprints responding devices, and flags the ones that look like surveillance gear.
- Looks for IP cameras by open RTSP ports (554), ONVIF responses, and known camera hostname patterns.
- Identifies device manufacturers using MAC address OUIs — often before you know the model.
- Picks up Bluetooth advertisements from common trackers and nearby BLE-enabled devices.
- Tells you what looks benign and what deserves a second look.
A hidden lens can still catch the light.
Aim your iPhone at the smoke detector, the screw, the air vent, the picture frame. The reticle overlay helps you spot the kind of reflections a lens can produce.
- Live rear-camera preview with a high-contrast reticle tuned to highlight the circular glint a lens can produce.
- Useful across common hiding spots — USB chargers, alarm clocks, books, ceiling tiles.
- No flash dependence: works in normal room light, no need to dim the lights or close blinds.
- Optical inspection can surface cameras that aren't on the network — ones the scanner won't see.
Powered-off doesn't always mean invisible.
Concealed electronics can distort the local magnetic field even when they aren't transmitting. Spyzero samples your iPhone's magnetometer ten times a second and surfaces deviations from a baseline you set.
- Live magnetometer readout in microteslas with a baseline-relative threshold you set yourself.
- Pass within a few inches of any flagged object — wall, vent, plant, book — and watch the field react.
- Can surface devices that don't show up on Wi-Fi: SD-card recorders, battery-powered cameras, audio bugs.
- Many everyday objects (speakers, magnets, rebar) also cause readings — use it as a hint, not a verdict.
One scale across all three tools.
Every signal — a port, a lens reflection, a magnetic spike — feeds the same severity scale, so you can tell at a glance what looks fine and what's worth a closer look.
Honest answers.
Counter-surveillance is full of overclaims. Here's what Spyzero can and can't do.
Ask us something →Will this find every hidden camera?
No tool can promise that, and we won't either. Spyzero is a heuristic aid: it surfaces signals from common consumer surveillance gear — networked cameras, BLE trackers, lens reflections, and electronics dense enough to disturb a local magnetic field — but false positives and false negatives are both possible. A device that's powered off, recording to local storage, off the network, and well-shielded is genuinely hard to find without professional gear. Spyzero gives you three independent ways to look so you can make a more informed judgment.
Do I need to be on the same Wi-Fi as the camera?
For the network scanner, yes — connect to the same Wi-Fi the room provides. That's where most rental, hotel, and Airbnb cameras live. The lens scope and magnetic tools work offline.
How long does a full sweep take?
A Wi-Fi scan completes in 5–15 seconds depending on network size. A thorough optical sweep of a hotel room is two to three minutes. The magnetic pass is another minute. Most people are done in under five.
Does Spyzero send any data anywhere?
No. There is no account, no cloud, no telemetry of what you scan. The camera feed is processed on-device. The network scan results stay on-device. The magnetometer samples stay on-device. We can't see your scans even if we wanted to.
What iPhone do I need?
Any iPhone running iOS 18 or later. The magnetometer is in every iPhone since the 3GS, so even older supported devices work. A newer phone scans the network faster.
How is this different from a $40 RF detector?
RF detectors flag any radio signal — your own phone, your laptop, the neighbor's microwave. You spend the sweep chasing your own tail. Spyzero is selective: it identifies what each device is, not just that one exists.
The whole product runs on your phone. That's the point.
Spyzero is a security tool. A security tool that sends your data anywhere isn't a security tool. There is no Spyzero server processing your scans, because there is no Spyzero server.
Sweep the room. Sleep better.
Spyzero is on the App Store for iPhone running iOS 18 or later. Two minutes to peace of mind.
