| LifeShield | LifeShield is the first national, professional grade and professionally monitored wireless security system that provides superior protection and the best value in home security. Other home security systems typically fall into two categories: cheap and ineffective or expensive and one-dimensional. Customers are fooled into thinking they areprotected, but many burglars can actually defeat these cheap systems in under 30 seconds. And traditional alarm system companies charge thousands of dollars to put sensors on first floor windows and doors, and even more on bedroom windows and upstairs entry points. Most people simply can't afford what they really need. With LifeShield customers get better protection, reliability, and superior control compared to traditional analog-based security systems. Plus, LifeShield was one of the first to provide remote access to your home security system. With LifeShield, you have always been able to log into your system from anywhere in the world for free. Some of the other systems are finally able to offer you this same type of access, but you'll pay for it. They'll add an extra cost to your monthly monitoring payments. And with LifeShield you can access your system even more easily with apps for iPhone, Blackberry, and Android. Look for our iPod application launch coming in July. We make home protection easy and convenient.SpecialtiesHome Security, Home Automation, Alarm Systems, Security System Installation, Home security systems | $13.5M | Series C | Jul 01, 2007 |  |
