Each time another Black Friday rolls around, there is an opportunity to score the most cutting-edge smart home gadgets at attainable prices. Today, it's difficult to find any consumer electronics, whether it be TVs, cameras, or watches, that aren't integrated with popular smart home platforms. Even so, with manufacturers taking chances with innovative features to gain advantages, not all these devices are worth investing in.

Thankfully, plenty of smart products with years of proven performance make for worthwhile purchases or gifts.
