A Wi-Fi camera is a radio transmitter. The products labelled “Japan-market model” (Panasonic KX-HDN215, ATOM Cam2) are approved only under Japanese rules and carry no FCC ID or UKCA/CE marking, so they are not authorised for use in the US or UK — and their apps are usually tied to Japanese accounts.

2.4 GHz Wi-Fi: give the band its own name during setup

Almost every pet camera is 2.4 GHz only. If your router combines 2.4 and 5 GHz under one network name, pairing often fails — split the bands temporarily or use a guest network. Note also that UK and EU routers may use channels 12 and 13, which US-market cameras do not scan; if your camera cannot see the network, move the router to channel 1–11.

Cloud or SD card — and where the footage lives

The “Storage” row shows whether a model records to SD, to the cloud, or both, and the “Subscription-free” column shows whether a monthly plan is required. For cloud models, check the maker's privacy policy before buying for where recordings are held and how long they are kept — and in the UK, footage of your home is personal data under UK GDPR.

Where you may point it, and the microphone

Filming inside your own home is fine. Once the camera takes in a shared hallway, a neighbour's property or the pavement, other people's rights come into it, and housemates and guests should know recording is on. Two-way audio also records sound: several US states require all parties to consent to recording a conversation, so turn recording off when visitors are over.

Frequently asked questions

Is a monthly subscription required?

For basic monitoring, SD-card models (Tapo, Wyze) need no subscription. Cloud recording and AI detection often require one.

Can I give treats through the camera?

Yes — treat-dispensing models like Furbo or Petcube let you toss treats from the app while you're away.

Can it see at night?

Most models have infrared night vision, showing your cat in monochrome even in a dark room.
