Keep tabs on Oplink Security's TripleShield package (pictures)

Oplink Security's $349.99 TripleShield package includes a motion detector, a panic siren, two open/closed contact sensors, two keychain remotes, two wireless cameras, and the OPU router that controls all of it over Wi-Fi. If you don't want the cameras, you can save $150 and go with the $199.99 AlarmShield package.

The OPU control device plugs into your home router, then manages your security system over Wi-Fi.

Oplink's open/closed contact sensors attach easily to doors and windows, and will alert you if someone ever tries to come in.

The included motion detector will trigger the alarm if it sees anyone sneaking in front of it.

You can place the panic siren wherever you'd like -- you'll need to be able to plug it in, though.

Oplink's cameras are easy to install and work over Wi-Fi.

When the lights go out, Oplink's cameras automatically go into night-vision mode (and automatically make you look like a creep).

Along with in-app controls on your smartphone, you'll be able to arm and disarm your system remotely using one of the two keychain remotes that come with the system.

Your smartphone will alert you immediately if the alarm is triggered, even if the Oplink app isn't running.

Unlike the fee-free iSmartAlarm, Oplink charges $19.99 a month to use the TripleShield package. The camera-less AlarmShield package is cheaper, at $9.99 per month.
