Amazon's 3rd Gen Echo Dot is now bigger and louder thanks to a new speaker. It also has 4 microphones instead of 7 now but that hasn't affected its listening capabilities in my experience.
Amcrest's 4K Security Camera System has razor sharp image quality at 8MP and a super wide angle lens. This review includes the Amcrest IP8M-2496EB, IP8M-2493EW, IP8M-2493EB, and NV4108E-HS NVR. This system might just be the best 4K security camera system for the money as the entire system costs around $740 for 4 cameras and the NVR.
