It sounds obvious, but the best time to get security cameras is before your home gets broken into. I recently had a break-in before I could install any security cameras on my new home, and I'm convinced the reason was that I was one of the few homes around the block with no cameras. If your home also doesn't have any cameras, Amazon's Memorial Day sale currently has Blink cameras discounted up to 50% off with bundles designed for those just getting started or people looking to expand on their current system.
When it comes to Blink cameras, you'll need a Sync Module if you want to use local storage instead of paying for cloud storage with the Blink subscription plan. The Sync Module gives you local storage for your videos with a USB stick. Most bundles have the option to include the Sync Module 2 for much cheaper than buying it individually (sometimes for as little as $5 more). The Blink subscription plan starts at $3 monthly for one device and up to $10 for multiple devices. You can learn more about the subscription options here.
The Blink Whole Home Bundle is a good way to get started
The Blink Whole Home Bundle has everything you need to get started with a security camera system, and right now, it's $131.97 (originally $199.97) after a 34% discount. It comes with the Blink Video Doorbell, a Blink Outdoor 4 camera, the new Blink Mini 2, and the Sync Module 2 for local storage. The new Blink Mini 2 also works as an outdoor camera if you get the Blink Weather Resistant Power Adapter, so you can essentially get two outdoor cameras if you prefer that.
Save with the Blink Outdoor 4 if you already have a security camera system in place
This bundle is great for those who already have the basics (like a doorbell camera) in place and just need more cameras. The Blink Outdoor 4 is a great outdoor wireless camera, and the four-camera bundle is 50% off, so each camera is essentially $42.50 instead of $119. This bundle still includes Sync Module 2, so you'll be able to use local storage if you want to avoid the monthly subscription.
