Maybe it's because people are becoming more privacy-conscious these days, but everyone seems to be doubling down on surveillance systems for their homes and vehicles. If you haven’t seen that dash cam video of the staged car crash scam, you really should — it's definitely a wake-up call for the need to document everything.

If you’re looking to get started or to build out your existing home security system with more cameras, perhaps with a video doorbell or a spotlight or additional accessories, take advantage of today's Black Friday sales on some of the best home security cameras available before time runs out.

Save big on indoor and outdoor home security camera systems, video doorbells, and single cameras to keep an eye on pets.

Security cameras can protect your home, inside and out. Their presence outside your house can be crime deterrents, simply because they’re a more obvious visual indicator that your property is being monitored.

A lot of packages are going to come your way in the next few weeks, so keep your doorstep secure (along with the rest of your house) with deep discounts on cameras from Blink, Arlo, Ring and more

Amazon has an early Black Friday deal on a pair of Blink Mini 2 security cameras. Released earlier this year, the cameras have a built-in spotlight and person detection with an optional subscription.
