You can buy into Brinks Home Complete, or purchase the Nest Security System see above at a discount through Brinks. The service is really focused on providing the monitoring for you, which comes in relatively cheap in industry terms at $29 per month, after hardware costs. The one caveat is to expect to sign a three year contract, with early exit penalties coming into play 30 days after purchase. ADT is an established security company that offers equipment tied to a subscription based monitoring service, most of which will require professional installation that the company can provide. 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.
