What it finds · Likely

Cameras and doorbells

Video doorbells and security cameras, by their Wi-Fi and Bluetooth radios.

What it is

A connected camera: video doorbells, home and business security cameras, dash cams, baby monitors and trail cameras. Also transit and fleet vehicle cameras, which share hardware with body cams.

Who uses it

Home owners, small businesses, landlords, fleet operators. Very common in residential streets.

What it can see

Video, often audio, of whatever it points at; many record on motion and keep clips in the cloud or on a card. Doorbells typically cover the approach and some of the street.

What it can't do

Range is limited to its field of view. It does not interact with your phone; the signal you hear is its Wi-Fi link or a Bluetooth setup channel.

How Wavelens finds it

Wi-Fi BSSID vendor prefix and SSID naming patterns, BLE advertisement names and company IDs, matched against public signatures for camera makers.

What to do when you see one

Nothing is required. A camera that is resident at a place you visit often will be marked as a known fixed emitter and go quiet.

Phone or companion?

The phone alone hears these over Bluetooth and Wi-Fi. A Spotter companion ($64) hears them further away.

Classification is a best-effort guess from public signature data. Check before you act on it. None of this is a claim about who owns a device, why it is there, or whether it is lawful.

  • IEEE OUI / MA-L registry (Wi-Fi and Bluetooth address vendor prefixes)
  • Bluetooth SIG assigned company identifiers
