Whether you’re at home or away, a video doorbell is a lovely gadget that can help you check on who’s outside your door at any time. And right now, the Blink Video Doorbell is on sale for just $30 on Amazon — that’s 50 percent off its original price — so it’s the perfect time to grab one.

The Blink video doorbell boasts impressive technical specifications that make it a worthy contender in the smart doorbell market. It features 1080p HD video quality for crystal-clear daytime viewing and infrared night vision for round-the-clock monitoring.

While not the latest version, the Ring Indoor Cam (2nd generation) remains a reliable smart home purchase. Right now on Amazon, you can get one bundled with a Ring Battery Doorbell for $60 off.
