How Does it Work?

When your system is armed in “away mode,” your motion detectors become active. As the sensor warms up, it sets up a grid in the range of its eye (a 30’ * 50’ block). The sensor detects heat and movement across this grid. If anything blocks too many of the grid zones, the motion sensor trips, sends a signal to the panel, and within 17 seconds the Vivint Central Monitoring Station is connected to your panel to make an informed dispatch if necessary.
A human, even a child, will block many more of the grid zones than a cat or dog will. Beyond that, the sensor even has a sensitivity level that can be adjusted for families with very active animals. The faster a pet moves and changes direction, the higher chance it has of blocking more of the grid zones and setting off the alarm. There are usually no problems if the animal is just moving quickly across the floor, but if the animal runs and jumps at just the right angle up the stairs, or onto a couch, it could set off the alarm. Again, with small cats and dogs, a sensitivity adjustment is all that is needed. Very few of us have a cat that is over 33 pounds, but if you do have a cat that large he is probably not a fast mover.

Grid Warm-up Time

Once the system is armed, the motion detector takes a few minutes to set up its grid. During this warm up time, it is essentially becoming comfortable with what is in the room. During these few minutes (not more than about 2 minutes) the sensor will not trip. After the brief warm up time, the motion detector will pick up all human movement that passes through its range of vision.

Away mode Vs. Stay mode

When a technician installs your system and sets up your motion sensors, they are set up specifically to only work in away mode. It would not do much good if the motion sensors were armed when you were in the home, because you would set them off when going to get a drink of water or answering the phone. The sensors are specifically created to only work when you are not home, or when you tell the system you are not there.
