## Key values

- **Category:** radiofrequency
- **Emission bands:** 2.4 GHz ISM; 5 GHz U-NII
- **Environments:** home, outdoor, workplace
- **Transmit power:** 0.1 W EIRP — Regulatory value — legally enforceable — Typical Part 15 consumer transmitter power. Transmit power is the regulatory or typical maximum; real devices often transmit below it and reduce power when link quality allows. [fcc-part15]
- **Duty cycle:** Cloud-recording cameras stream continuously; local-recording and motion-triggered units transmit only on events.

## Field strength by distance

- **30 cm:** 88,400 µW/m² — Computed estimate — S = EIRP / (4πd²) with EIRP = 0.1 W, d = 0.3 m [fcc-part15]
- **1 m:** 7,960 µW/m² — Computed estimate — S = EIRP / (4πd²) with EIRP = 0.1 W, d = 1 m [fcc-part15]
- **3 m:** 884 µW/m² — Computed estimate — S = EIRP / (4πd²) with EIRP = 0.1 W, d = 3 m [fcc-part15]

## Mitigations, most effective first

- **Switch to Power-over-Ethernet cameras with the radio disabled.** — Removes the transmitter while keeping the function.
- **Set cameras to event-triggered rather than continuous upload.** — Cuts duty cycle from ~100% to a few percent.
