Amazon just kicked off their Black Friday sale for Blink XT Security Cameras this morning. These are the weatherproof outdoor cameras that are completely wire-free and run for 2 years on a pair of (included) batteries. They achieve this by remaining in a low-power state until their motion sensors detect movement and begin recording instantly. There’s no monthly subscription fee with these cameras and you get free cloud storage. The Blink XT 1 Camera System is $78.99 and the Blink XT 2 Camera System is $149.99. These prices are $4 and $10, respectively, higher than they were during Prime Day, but they’re still a great deal. Where you’ll really start saving is with the 3 and 5 camera kits. The Blink XT 3 Camera System is $229.99 and the Blink XT 5 Camera System is $349.99. These are both the new lowest price that they have ever been. These kits come with everything you’ll need to start monitoring your property in minutes and they’re Alexa compatible, so you can pull up the camera feed by voice on your Fire TV or Echo Show. If you don’t plan to use them outdoors, the regular Blink Cameras are also on sale, starting at $66.99. Those are about 15-30% less expensive than these beefed up outdoor versions.
