What resolution do I need for a security camera?

1080p is the minimum for reliable face identification at normal room distances. 2K (2560×1440) provides noticeably better detail for reading text or seeing fine features. 4K is overkill for most indoor use — it generates enormous file sizes and requires more bandwidth, but makes sense for high-stakes monitoring of large areas or entry points.

Do security cameras work without internet?

Most cloud-based cameras (Ring, Nest) won't record or send alerts without internet. Local storage cameras (Wyze with microSD, eufy, Reolink) continue recording locally even without internet — you just can't receive remote alerts or view live footage until connectivity is restored. For critical security, local storage is more reliable.

Are indoor security cameras an invasion of privacy?

Indoor cameras are legal in your own home in all 50 US states. In some states, audio recording requires consent from all parties (California, Florida). Consider camera placement carefully — bedrooms and bathrooms are obvious no-go zones. Be transparent with household members and guests about camera locations.
