    If someone tries to break in, your
    Base Station alerts our monitoring
    center, then sounds a loud 95dB siren.


    It doesn’t need to be plugged in, so
    you can place it anywhere you like.
    We recommend by the front door.


    We use the entry sensors to guard the
    front and back door, plus two large and
    easily accessed first-floor windows.


    We use the motion sensors to cover two
    main rooms. That way, no matter where
    an intruder enters, the sensors will detect
    them as they try to pass through.

The all new touch-to-wake keypad. Lights up when you need to see it. Goes dark when you don't. It doesn't need power, just a good place to put it.

Detects Intruders, not pets.

Alarms that cry wolf? No thanks. We precision-engineered our motion sensors to detect the unique heat signature of humans. Not pets.

"This is one I'm hearing a lot
about now. You don't have to drill
anything. No wiring needed."
"Protecting your family is important,
but don't ever sign a long-term contract.
These are the good guys!"

for a lot less money."

word is spreading."
