Motion & Glass Break Sensors in Centennial, CO
The detection layer built and tuned for Centennial houses, from garden-level basements near Dry Creek Road to the tall window walls in newer builds.
If your system trips without cause, the fix is usually placement rather than replacement.
Sensors Are Where Systems Succeed or Annoy You
A panel is only as good as what reports to it, and sensor work in Centennial usually arrives as one of two requests: gaps that need covering, or false alarms that need to stop. Both come down to the same discipline. Motion sensors work by detecting heat moving across their field, which means a heating vent, a sunny window or a large dog will trip an untuned device reliably. Glass break sensors listen for a specific acoustic signature and need to be within range of the pane they are protecting, not tucked around a corner. Centennial Home Security places each device around what it must detect, then tests it against the way your household actually lives, including the pets. The result is a system people keep armed, which is the only kind that protects anything.
What Sensor Work Covers
New coverage or a rescue job on an existing system, the survey and the tuning are the same.
- 01
Entry contacts on doors and accessible windows
Magnetic contacts on every exterior door, plus ground-floor and reachable upper windows, with recessed options where appearance matters.
- 02
Motion sensors aimed across traffic paths
Positioned so an intruder crosses the detection field rather than walking toward it, which is how the sensor responds fastest.
- 03
Pet-tolerant motion tuning
Mounting height and sensitivity set for your animals' size, so the dog can use the hallway overnight without triggering a dispatch.
- 04
Glass break coverage for large panes
Acoustic sensors placed within range of patio sliders, picture windows and basement glass, tested with a calibrated trigger.
- 05
Vent, sunlight and heat-source avoidance
We survey each proposed position for the things that cause false trips and move devices before they become a problem.
- 06
Garden-level and basement window coverage
The openings burglars actually favour on Front Range homes, often left out of a builder-grade system.
- 07
Garage and interior door contacts
The door between the garage and the house is frequently the weakest link, and it gets its own zone.
- 08
Water, smoke and carbon monoxide sensing
Environmental detection placed where it belongs: near water heaters, laundry, sump areas and sleeping floors.
- 09
Zone naming and mapping
Each device is labelled so the keypad and the monitoring operator both read something meaningful instead of Zone 7.
- 10
Live walk testing
Every sensor is tripped with you present, and the coverage boundaries are demonstrated so you know exactly what the system sees.
Survey, Place, Then Prove It
Coverage survey
We walk the house looking for gaps and for false-alarm risks at the same time. You will hear which openings are priorities, which are unlikely entry points, and where a current sensor is mounted somewhere it should not be. Roughly half an hour for most homes.
Placement and programming
Devices are mounted at the correct height and orientation, then programmed into the panel with clear zone names. Pet-tolerant models are set to your animals rather than to a factory default that assumes an empty house.
Walk test and tuning
With the system in test mode we trigger every device while you watch the keypad, then re-tune anything that fires when it should not. Households with pets get a second pass, because the difference between a usable and an abandoned system is often one sensitivity setting.
Why Our Sensors Stay Armed
False alarms are treated as a design failure
A system disarmed because it cries wolf is worse than no system. Preventing that is a placement decision made on the first visit.
Pets are planned for from the start
Almost every home we work in has an animal in it. Height, angle and sensitivity are adjusted to the actual dog, not to a category on a spec sheet.
Basement and garden-level glass gets covered
These are the openings most builder-installed systems skip and the ones most often used. We look at them first.
Close the Gaps, Stop the False Trips
Whether your system misses the basement windows or fires every time the furnace kicks on, both problems are solved with the same careful survey. Book a walkthrough and we will map the detection layer properly.
