Submission + - DIY security system? 3

An anonymous reader writes: For geeks that want to secure their home, it seems that the choice of Do It Yourself solutions are limited. And in case you prefer to use a company, most of them require to subscribe to a contract for 3 years that costs at least $20 a month. In case you want to make a DIY security system without a monthly fee, few options are available. Some products (such as ismartalarm, Lowe's Iris system or also the fortress security) let you install your own system but seem not to be very mature (for some the alarm is not loud, for others they do not use the internet and only a land line, etc.).

Is there any recommendation for a basic DIY home security system for monitoring the house and just have notification by e-mail or through a mobile application? Is there any open standard for home automation and security devices? Any suggestion about how to build something simple, affordable and efficient?

      Or just change the sense of the signaling. Have it send all's well messages. If they top, there's a problem (which may be that the internet connection is down).

      Depending on how often that happens, it might be reasonable.

  • If you want an alarm system, check out a DSC PC1832 alarm box or kit, which can be had for 100-150 online, you run your own wires/sensors, wireless options available. You don't have to connect it to monitoring service, just hope that baddies will run off when the alarm goes off, cause they think police have been called. I've paired mine with a VM101 module by http://www.myvirtualmonitoring.com/ [myvirtualmonitoring.com], which offers low cost monitoring via ethernet/cell tower and soon looks like WiFi, which can txt and/or call you
