Long gone are the days of analog alarm bells. One system which looks interesting for all digital protection is the InGrid Digital Home Protection System, priced at around $300 for a standard home size kit.

The InGrid Digital Home Protection System is designed to be nearly impossible to defeat, says its maker. It “has system redundancy with multiple control points and no master control panel, which is known to be defeatable by intruders in seconds.” It has an always-on broadband connectivity feature for sending notification to a monitoring service of any changes, can let users customize its features via a Web interface, can notify you via text messages to your cell phone if there are problems and includes a two-way, key chain remote to arm disarm the system.
