My Favorite Amazon Deal of the Day: The Blink Outdoor 4

Whether you're shopping for your very first security camera or already have a system at home you're looking to grow, you might find something worthwhile in Amazon's sale section on Ring and Blink cameras. As Amanda Blum, our smart-home expert at Lifehacker, mentioned in her review, the Blink Outdoor 4 is a worthwhile entry-level wireless security camera-and right now, it's $39.99 (originally $99.99) after a 60% discount. You can also get bundles with multiple cameras starting at 60% off. This is the lowest price I have seen for this particular camera, after checking price tracking tools, and that's why it's my favorite Amazon deal of the day.

The Blink Outdoor 4 is a wireless camera, meaning you'll be using 2 AA lithium batteries, which last for up to two years. The camera is also weather-resistant, has motion-activation alerts, a live-view mode (up to five minutes without a Blink subscription plan), shoots in 1080p, has two-way audio, and works great with the Alexa ecosystem. (Unfortunately, it is not compatible with Google or Apple Home Kit.) You'll get a Sync Module 2 with your order, which gives you local storage for your videos with a USB stick, meaning you don't need to get the Blink subscription if you don't want to. The camera offers a 143-degree diagonal view wherever you set it up, and an optional person-detection feature if you get the Blink subscription plan.

Keep in mind you will need a Blink subscription to use all of its features. The Blink subscription starts at $30 a year for the Blink Basic Plan. You can also get the Blink Plus Plan, which costs $100 a year and has more features, the most important of which is having an unlimited number of devices hooked up to your account.
