Lumixi turns two Android phones into a private video baby monitor. Old phone = Camera; daily phone = parent Monitor. Pair by QR or short code—no account or ads. Encrypted video/audio stream between devices. When nobody watches, Camera sends nothing. Premium covers two Monitor seats; one camera active at a time. Camera is free. Monitor needs Lumixi Premium (7-day Google Play trial if eligible). Android only—no iPhone. Limits: not medical, not an alarm, and night mode is not infrared.
