Hidden Camera Detector Spot vs StellarTrack AR

You check into a hotel room, a holiday rental or a changing room, and the thought arrives: is anything watching? Spot gives you five real instruments and a checklist so you look everywhere. It is deliberately honest about what a phone can and cannot do — see the list below of what no app can find, including this one. INFRARED SWEEP Almost every hidden camera that works in the dark floods the room with infrared at 850 or 940 nanometres. Your eyes cannot see it; the front camera nearly can, because its infrared filter is far weaker than the rear camera's, so that light lands on the sensor as a pale violet-white dot. Turn the lights off, open the infrared sweep, and move slowly around the room. Spot lifts the shadows so a faint infrared source separates from a dark room instead of vanishing into it, and rings anything abnormally bright. LENS GLINT SWEEP A camera lens is a retroreflector: shine light at it and it sends light straight back, which is why animal eyes flash in a photograph. Spot lights the torch and looks for that signature — a small, very bright point that appears from one angle and vanishes from another. Glass and polished metal do the same, so every ring is a prompt to walk over and look, never a verdict. THE ROOM CHECKLIST Most hidden cameras are found by looking carefully, not by waving a phone around. Spot walks you through the places they are actually installed — smoke detectors and vents, anything facing the bed, sockets and USB bricks, shelves, bathroom fittings, and mirrors, including the fingertip test that tells a normal mirror from two-way glass. SAVE WHAT YOU FIND Anything that looks wrong, capture it. The photo and your note stay on your phone, so you have a record if you need to raise it with a host, a hotel or the police. EVERYTHING STAYS ON YOUR PHONE The camera feed is analysed live, in memory, and discarded. Nothing is recorded or uploaded, and there is no account. WHAT SPOT CANNOT DO It cannot find a camera that is powered off. It cannot find one with no infrared that is hidden behind an object, and it cannot see through walls. It reads your own Wi-Fi and nearby Bluetooth advertisements, but it does not decode radio transmissions — no phone app can, whatever the category claims. A ring on screen means "brighter than its surroundings", which is a reason to go and look. FREE • The full room checklist for hotels, rentals, your own home, changing rooms, offices and cars • Run the network scan and see how many devices answered • The complete, honest list of what no phone app can find Charging for a written checklist would be taking money for nothing, so it is free — and it is the only thing that finds a daylight camera, a powered-off one, or a two-way mirror.

StellarTrack shows you where weather satellites are in the sky right now, overlaid on your camera view, so you can aim an antenna at them with confidence. Point your phone at the sky. Each tracked satellite appears as a marker where it actually is, with live azimuth and elevation you can read off directly. Lock onto one and an arrow guides you until you are on target. WHAT IT TRACKS • METEOR-M2-3 and METEOR-M2-4 — Russian polar orbiters broadcasting LRPT • GK-2A — Korean geostationary satellite • GOES-18 — NOAA geostationary satellite over the eastern Pacific FEATURES Live AR pointing Satellite markers rendered in a live camera view, anchored to true north and gravity. Aim the phone the way you would aim the antenna. Precise azimuth and elevation Read the exact bearing and elevation for any tracked satellite. Positions are computed on device with the standard SGP4 orbital model. Pass predictions See when each polar orbiter rises next, how long until it does, and how high it will climb at peak. Plan a reception session before you set up. Below-horizon preview Satellites that have not risen yet still appear, dimmed, so you can see which direction the next pass will come from. Compass health warnings Phone compasses drift near metal and magnets. StellarTrack tells you when the heading has become unreliable instead of silently pointing you the wrong way. Works offline Location, compass and all orbital mathematics run entirely on your device. Only refreshing orbital elements needs a connection, and cached data keeps working in the meantime. Multilingual Full English, Simplified Chinese and Traditional Chinese interface. PRIVACY StellarTrack collects nothing. There are no accounts, no analytics, no advertising and no tracking of any kind. Your location is used on your device to compute bearings and is never uploaded. The camera feed is never recorded or saved. The only network request the app makes is downloading public orbital elements from CelesTrak, identified by each satellite's public catalog number, containing no personal data. A NOTE ON ACCURACY Orbital positions come from public elements refreshed every few hours and are accurate enough to aim an antenna. In practice your phone's compass is the larger source of error, which is why the app warns you when calibration is poor. This is a pointing aid, not survey-grade instrumentation. REQUIREMENTS Requires a device with ARKit support, a camera, and location services enabled.
