What a keychain camera looks like and how to catch one

Where the lens hides on a key fob

The lens is usually on the narrow end of the fob, the end opposite the key ring. On a real car remote that end is plain plastic or has a small hole for a hidden emergency key. On the camera version it has a pinhole, sometimes behind a dark tinted window that looks like the infrared port some older remotes had.

So a fob lying flat on a table with its end facing you is looking at you. A fob hanging from a bag strap or a belt loop points down or forward depending on how it swings. Other keychain shapes, such as small flashlights, bottle openers and cartoon charms, put the lens at the front where a light or a face would be.

Why a keychain camera is hard to find

• Very short battery. Most run somewhere around an hour of recording, so they are switched on for a specific moment and carried away afterward.
• Local recording. Video goes to a micro memory card inside. There is no stream to find on Wi-Fi.
• Little or no radio. Most have no Wi-Fi or Bluetooth, and those that do often use them only for setup.
• It moves with the owner. It is on the table for a meeting or a date, then back in a pocket.

Signs you can check by eye

The strongest clue is behavior. A set of keys placed on a table and then turned so the end faces you, or picked up and set down again pointing somewhere else, is odd. Nobody aims real car keys.

If you can look at the fob itself, check for a pinhole or a small dark window on the end, a USB port or memory card slot hidden under a flap on the side, buttons that do not match any car brand logo, and a tiny blue or red light when a button is pressed. A key fob with no key blade and no brand mark that still has a charging port is not a car remote.

Which Candor check fits a keychain

The lens finder is the one that can help. If the fob is lying still on a table, sweep its end with the flashlight on. A lens throws back a small, sharp point that stays put as you shift. Glossy fob plastic and metal rings will glint too, so check any mark by eye.

The magnetic sensor is weak evidence here. A real car remote has a battery and a circuit board as well, so both raise the reading. It only helps if the object is supposed to be a plain metal or plastic charm.

The Wi-Fi camera scan and Bluetooth scan are unlikely to show a keychain camera because most have no live connection. Run them if you have a reason to, but do not take an empty result as a clear.

When it is in someone's hand

You cannot sweep a person or their keys. If someone keeps a fob pointed at you, you can ask about it, move so it no longer has a view, put a bag or menu in front of it, or leave. At work, report it to HR or security. If you think you were recorded somewhere private, such as a restroom or a changing area, report it to police. The spy camera detector guide explains what phone tools can and cannot do more broadly.

Check a key fob left on a table

1. Notice which way it pointsSee whether the narrow end faces you, a bed, a bathroom door or a keyboard. A real car key has no reason to be aimed.
2. Sweep the end with the lens finderOpen the lens finder in Candor and hold the phone level with the table about 30 cm from the fob. Move slowly side to side and watch the end for a tight, steady point of light.
3. Look closely at the end and the sidesCheck for a pinhole, a dark window, a sliding flap, a USB socket or a memory card slot. Real remotes usually have a brand mark and a key blade or key release button.
4. Press a buttonIf it is yours to handle, or you have been handed it, press a button. A camera fob may flash a small status light instead of doing nothing.
5. Photograph and reportTake a photo of the fob and where it was. Give it to the host, manager or police rather than opening it or wiping the card.
