Like Brinks, ADT pushes for a three year initial contract, which afterwards is renewed monthly, but unlike all the other firms listed it's not very transparent about pricing. While other companies are happy to offer a single fee per product/package, ADT pushes on custom sales for custom packages, which means it’s difficult to make a direct price comparison. Frontpoint Security sells itself on ease of use, with a DIY home surveillance and security kit based on free standing sensors that don't require any wall mounting, drilling, wires, etc. However, the equipment is sold as part of a contract term package, and pricing will depend on the period committed to upfront. Plans cost between $34. 99 to $49. 99 a month, with the cost of equipment discounted to $99 if you commit to a three year contract. Like its rivals we’ve just mentioned, Vivint offers a combined equipment and monitoring service package, with everything run through a cellular network with backup batteries. However, Vivint SmartHome is something of a premium option, requiring a five year term and monthly prices that can stack up. Even so, some argue that you get what you pay for, and Vivint certainly has a strong reputation in the security industry. Link Interactive costs less than most of the other solutions listed here, plus it boasts an admirable range of security options you can customize yourself.
