P.C. Richard and Son offers the Blink XT Home Security Camera System for $78.99 with free shipping. That's the lowest price we could find by $21. (For further comparison, we saw it bundled with an Amazon Echo for the same price three weeks ago.) Compatible with iOS or Android devices, the system includes a wire-free indoor/outdoor camera, sync module, and mounting kit. Features include:
up to 1080p video resolution
night vision, motion detection, & temperature sensor
alerts, live viewing, and remote control via Blink Home Monitor mobile app
voice control via Amazon Alexa
free cloud storage for up to 2 hours of clips
2-year camera battery life
