Forty-three percent of U.S. households with internet access have a security product with online capabilities such as a self-monitored smart camera, video doorbell or a professionally monitored security system, said Jennifer Kent, vice president of research at Parks Associates, a consumer technology market-research firm.

“There is a wide choice of devices and systems on the market today, and the market has grown as self-install solutions, lower-cost devices and lower-cost services have come to market, attracting middle-income households and renters,” Kent said in an email.

When Kent’s firm surveyed consumers about the services they might like to add to their existing home security systems, 66 percent indicated they’d be interested in adding fire and gas safety monitoring.
