FOR SALE: TWO BRAND-NEW-AND-BOXED BLINK ADD-ON OUTDOOR CAMERAS 2 brand new Blink cameras (Model BCM01400U) still in sealed cartons. These need a Synch Module 2 to connect them to the free Blink app. And they then work wirelessly with an Alexa. Despite rumours, users can avoid paying Amazon a monthly subscription for Cloud storage. Simply plug a USB stick into the Synch Module 2. Bingo! Each camera requires 2 x AA lithium batteries (not supplied) which usually last for several months. This is an entry-level system but works quite well even at night and can be set up in 15 minutes.
