The Sync Module 2 contains a 2.4GHz Wi-Fi radio to connect to your home network and an RF radio to communicate with the camera. It has blue and green status LEDs on the front, a mini USB port for power, and a USB-A port for connecting to a storage device such as a thumb drive (not included). You can store video locally on the drive and share it, or you can enroll in a Blink Subscription Plan for cloud-based storage and access to certain features. Below the video panel are three buttons. The Save button saves video from a live viewing session and the Talk button is used for two-way talk. Tap the More button to open the Device Settings screen, which is organized into several menus. The General Settings menu lets you change the device name, configure temperature alerts, and view your network and Sync Module signal strength. The Motion Settings menu lets you adjust motion detection sensitivity, choose a recording type (all motion or person-only), create motion zones, and configure a retrigger time for how long after a motion event the camera will begin detecting motion again (between 10 and 60 seconds). Like all other Blink devices, the camera works with the Blink Home Monitor app (available for Android and iOS). Once connected, the Blink Outdoor 4 appears on the app’s home screen in a panel that displays the camera's last captured still image. The panel contains a photo button for taking snapshots and a video camera button that launches a live video stream. To view the video in full-screen mode, turn your phone sideways or tap the box in the upper right corner. No. Your Blink devices are automatically equipped with essential features such as live view, motion alerts and two-way audio.
