Cheap (and Efficient) Wire-Free Doorbell The Blink doorbell is a second-generation product with far better improvements than its first. With it, you receive the head-to-toe HD image of anything from a visitor’s face to deliveries left on your doorstep. You are protected both daytime and nighttime thanks to infrared night vision. The two-way audio feature lets you communicate face-to-face through the Blink app, so you can greet visitors, leave delivery instructions, or deter unwanted visitors from home. Unlike some other options, including the Ring video doorbell, which often costs significantly more frequently, Blink can provide a complete set of features at a tiny fraction of the price. While Ring is a household name, Blink’s product is cheaper and more widely available, which makes it a smart choice if you want to improve the security of your home. The battery life of the Blink doorbell is arguably the most impressive aspect of the device: With the three that are included AA Energizer lithium batteries and the Blink Sync Module, you can enjoy up to two years of uninterrupted usage before replacement of the batteries is required. This amounts to less maintenance and more tranquility. The Sync Module Core that comes in the box assists your doorbell in staying connected and responsive at all times. Installation is easy: you can set it up wire-free in a matter of minutes or connect it to your existing doorbell wiring if that’s what you want. If you choose to go wireless, you can repurpose a Blink Mini 2 camera (sold separately) as an indoor chime, or just rely on instant alerts delivered directly to your phone through the Blink app. Security features are improved with edge AI processing where the doorbell quickly identifies people at your doorstep. When you buy the Blink Subscription Plan (separately), you get better alerts each time a person is spotted, in addition to access to Blink Moments which connects several clips into one shareable video. There’s a free 30-day trial of the subscription plan right now for Prime Day. At just $29 for Prime members, the Blink Video Doorbell is one of the best Prime Day deals out there. See at Amazon
