A motion watcher on one device: it detects movement in view and alerts + logs (and records, if you like). Nothing streams unless you ask it to — if you'd rather see the picture on a second phone, the two-phone monitor pairs this camera to your pocket over your own wifi with a QR handshake, no server involved.
