DIY home security solutions in which homeowners install and monitor the systems on their own are in high demand. Consumer interest in these products is high enough that many have been funded by Kickstarter projects that raise millions of dollars. Startups aren't the only ones making money off the DIY demand. Products from corporate titans such as Google's Nest and Dropcam are also diversifying the market. In most cases these have been acquired, not developed by the big corporations themselves. Investment firms have also spotted an opportunity in the DIY home security market. For example, Sequoia invested early; in 2014, the firm dumped $57 million into SimpliSafe, which offers self installed security systems. All told, DIY systems are on track to take over 34 percent of the home security market by 2020. They're also projected to account for more than 62 percent of the market by 2035. The profitability of home security systems has become ever more apparent. That's resulted in intense competition within the industry as startups and big name corporations duke it out.
