Competition is heating up in the home security industry, with Groupon and Angie’s List running deals Thursday for 1st Security home security systems. Under “The Big Deal” section, Angie’s List offered a $25 voucher toward $100 worth of home security system upgrades, including installation. It cited 1st Security as a “highly rated service provider on Angie’s List” as a plus. Another offer bundled the deal with an Angie’s List membership for $34.99. Groupon is offering a security system from 1st Security for $79, which it calls a $300 value. Included are a touchscreen keypad and 10 security sensors -- nine window or door sensors plus one motion or glass-break sensor -- for homeowners who sign up for a 36-month monitoring agreement at $34.95 per month.
