What the Blink Outdoor 2K+ camera does

Blink's Outdoor 2K+ is a wireless security camera designed to monitor areas around your home, such as your front door, driveway, backyard or garage. Its compact design makes it a practical option for an entry-level home security setup.

The camera records in 2K, while digital zoom lets you get a closer look at activity around your property. Color low-light viewing also helps capture more detail after dark.

How setup and monitoring work

Setup runs through the Blink Home Monitor app, which lets you monitor your camera from your phone and customize settings like video quality and motion detection zones. This lets you focus alerts on the areas around your home you care about most.

One reviewer praised this straightforward process: "Just download the app, create an account and then follow the instructions to add the Sync Module Core and the Outdoor 2K+ camera."

The Sync Module comes in the box along with two AA batteries, a mounting bracket, a power adapter and a USB-C cable (both for the Sync Module). This device acts as the brain for the camera. It plugs into a wall outlet and connects to your home Wi-Fi. You can use this same Sync Module to connect up to 10 additional devices.

Talk to visitors from your phone

Along with 2K video, the Blink camera has two-way audio with noise cancellation, letting you hear and speak with visitors through your phone even when you're away from home.

That can come in handy when you're checking for a delivery, answering the door remotely or simply want to see what's happening outside without going to the door.

What to know before you buy

Before buying, it's worth knowing which features are included with the camera and which require Blink's optional subscription plan. A subscription unlocks additional features, including cloud video storage and other smart functionality.

The Blink Outdoor 2K+ camera runs on two AA lithium batteries, so you can install it outside without worrying about a nearby outlet. Blink says the batteries can last up to two years with typical use, depending on your settings and how often the camera is active. Its IP65 weather-resistance rating helps it stand up to rain and dust, while its compatibility with Alexa, Siri Shortcuts and IFTTT (If This Then That) makes it easy to add to your existing smart home setup.

Best Buy reviewers also praise the camera's everyday performance. I'd replace the existing final quote with a review that gives readers a specific reason the shopper liked the camera — such as video quality, motion detection, battery life or app performance — rather than the current quote saying only that the reviewer's "opinion changed."
