🎥Body camera detector: body-worn camera radios on Android

Worn cameras with a Wi-Fi or Bluetooth radio. Wavelens says "this maker's hardware", not "an officer".

The same radios ride in docking stations and on buses, so a hit on a vendor prefix alone is shown as Possible; turn on the second pass (Setup → Alerts, off by default) and it gets one soft tick on the first pass and the full alert only when it is heard again at the same spot. A companion radio parked on the hotspot channels hears these a block sooner.

What it is

A body-worn camera or related field equipment. Body cams are small chest or shoulder units that record video and audio when the wearer activates them.

Who uses it

Public-safety staff, security guards, transit and fleet operators, delivery and utility crews, and retail staff. The same hardware is sold to all of these; Wavelens cannot tell them apart.

What it can see

Video and audio from the wearer's point of view, typically only while recording. Many models keep a short pre-record buffer. Some units upload clips to a dock or over a cellular link.

What it can't do

Most record only when activated, not continuously. Hearing the radio does not mean it is recording; the Bluetooth link is usually for pairing with a phone app, a vehicle system or a holster sensor.

How Wavelens finds it

BLE advertisement names and manufacturer company IDs, and Wi-Fi SSID/BSSID vendor prefixes, that match public signatures for known camera makers. Names that mark transit or fleet kit are classified as cameras instead.

What to do when you see one

Nothing is required. The card shows the device name or address tail so two units in the same minute can be told apart.

Phone or companion?

The phone alone detects this over its own Bluetooth and Wi-Fi; no extra hardware is needed. A Spotter companion ($64, ESP32) on the dash hears further and can park on single Wi-Fi channels a phone only visits briefly. Full Spectrum ($499, a Raspberry Pi with RTL-SDRs plus a Spotter) adds sub-GHz sensors and radio, which this kind does not need.

Questions

Can a phone detect a body camera?

It can hear body cameras that use Bluetooth or Wi-Fi, which many models do for pairing with a phone, a vehicle system or a holster sensor. Wavelens matches the maker's registered company ID, service and name patterns. A camera with its radios off is not detected.

Does a hit mean someone is recording me?

No. Hearing the radio says the hardware is nearby, not that it is recording. Most body cams record only when the wearer starts them.

Can it tell a public-safety officer from a security guard?

No. The same hardware is sold to security firms, transit and delivery fleets and retail staff. Wavelens names the maker's hardware, never the wearer.

Can hits wait until they're heard a second time?

Yes, if you turn it on (Setup → Alerts, off by default). Docking stations and buses carry the same radios, so with it on a match on a vendor prefix alone gets a soft tick the first time and a full alert only when it is heard again at the same place, which cuts false alarms.

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.
