Walmart's pre-Prime Day sale has savings of up to $150 on Google and Nest smart speakers and security cameras

Smart speakers are great, but sometimes you want a little more information at your disposal, in which case, it's worth looking into a smart display.

The Google Nest Hub smart display also has the Google Assistant built into it, but with the screen, it can show information like your route to work, the weather, YouTube videos, and more.

The Google Nest Hello smart doorbell is a great way to heighten your home's security. In the Nest app, you can see a live feed of whoever or whatever is outside your door. You'll also get notifications when someone rings the doorbell. The device is well-designed and integrates with other Google Nest products, so you can see a feed of the video on your Google Nest Hub, for example.

If you like the idea of a security camera that integrates with your smart home but you don't necessarily want a new doorbell, then the Google Nest Cam might be for you. The Nest Cam is a great outdoor security camera, offering a crisp 1,080p image with features like a built-in motion sensor, night vision, and more. Like other Nest devices, the Google Nest Cam integrates with other Google Assistant-powered devices too, which is great for those trying to build a smart home ecosystem.
