Why sensors are the foundation

Cameras show you what happened. Sensors are what actually triggers the alarm and the response. They are the trip-wire of the whole system, and the reason a break-in is caught the moment it starts rather than after the fact.

Why sensors are the foundation

Most break-ins start at a door or window

This is where the data points. FBI figures show the large majority of break-ins happen through a door or a window, often one left unsecured. Sensors put a guard on every one of those points, so nothing opens without you knowing.

Most break-ins start at a door or window

The main types of sensors

Entry sensors. On doors and windows, they alert the instant the two parts separate.
Motion sensors. Cover a room or hallway and catch movement once someone is inside.
Glass-break sensors. Listen for the sound of a window shattering, even before it opens.

Where to place them, and how many

Cover every exterior door, every accessible ground-floor window, and add a motion sensor on a main path through the home. More is not always better. The right points matter far more than the count, and we map them for your specific layout.

Where to place them, and how many

What to look for in sensors

Wireless with long battery life. Easy to place and low maintenance.
Tamper alerts. So you know if a sensor is removed or interfered with.
Works with your panel. Every sensor should report to one hub and your app.
Low false-alarm design. Good sensors tell a real event from a pet or a draft.

How sensors fit your system

Sensors sit at the base of everything. The panel listens to them, monitoring reacts to them, and cameras confirm what they pick up. Take the sensors away and an alarm has nothing to trigger it.

How sensors fit your system

What it costs

Each sensor is inexpensive on its own, so the real number depends on how many doors and windows you protect. We will count the points that matter for your layout and give you a clear total on the call.

(855) 487-0595
How do door and window sensors work?
Two parts sit on the door or window and its frame. When they separate, the sensor signals the panel and triggers an alert.
How many sensors do I need?
Enough to cover every exterior door and accessible window, plus a motion sensor or two. We can map it for your home.
Where should sensors go?
On every exterior door, ground-floor and accessible windows, and main interior paths for motion.
Do sensors work without power?
Sensors are battery powered and keep working in an outage, and a good panel has cellular and battery backup too.
