Blink Video Doorbell

Amazon's Blink doorbell undercuts Ring on price while delivering the features most people actually need: 1080p video, two-way audio, motion detection, and two-year battery life on AA batteries. No hardwiring required — you can install it in five minutes with a screwdriver. The day/night video is sharp enough to identify faces, and the app alerts are fast. For basic home security, it's the best value per dollar on the market.
