Amazon’s budget security brand, Blink, announced two new cameras during the company’s fall hardware event in New York City: the Blink Mini 2K+ and the Blink Outdoor 2K+. As the names suggest, these cameras sport 2K resolution to pick up more details. But it’s the Blink Arc accessory that makes these security cameras more interesting.
The Arc can combine two cameras and stitch the feeds together for a complete 180-degree view. The product of some glue-gun experimentation, a borrowed 3D printer, and some nifty AI tools, this accessory came together in just 60 days. “There’s this fatal flaw with pan/tilt cameras,” says Jonathan Cohn, head of product at Blink. “The cliché Mission Impossible scene, where they wait for the motorized pan/tilt to turn the other way and duck behind.”

Blink’s Arc is Cohn’s solution, initially cooked up in his kitchen, and it’s designed to eliminate your blind spots. He showed some photos of the early prototype, cobbled together using snap mounts and hot glue. He was able to get the right angle so that he’d walk out of the frame on one camera mounted on the front of his house and into the frame on another camera on an almost level horizon.
The junior mechanical engineer, tasked with perfecting the angle and necessary overlap, used an AI tool to stitch the videos together, and despite some warping, it looked promising straightaway. Cohn borrowed his kid’s 3D printer to build the first Arc and popped in a couple of third-generation Blink Mini 2K+ cameras. Before long, the computer vision team found a way to dewarp the video, and the Arc was producing an almost seamless 180-degree live view.
Part of the charm of Amazon’s budget security camera brand is the jerry-rigged nature of add-ons like the Blink Mini Pan-Tilt, which allows you to slot a Blink Mini camera into a base that adds pan and tilt functionality. The Blink Arc is very much in the same mold. You can slot in your existing Blink Mini 2 cameras or snag a couple of the new Mini 2K+ models. (It doesn’t work with Blink’s other devices.) As long as the cameras are the same type, the Blink app can stitch their views.
The Arc houses the cameras at just the right angle and enables them to use a single outdoor power supply. You can connect the Arc to a snap mount to set it up horizontally, vertically, or hanging under your eaves. The video stitching is done on the software side; you simply link the cameras in the Blink app as left and right, and get a panoramic view. Blink even worked out a way to pan and zoom on subjects, so when there’s an event, it looks much like a pan/tilt camera tracking a subject, but it’s really just zooming on the 180 feed.
