Motion & Glass Break Sensors in Sunnyvale, CA
The detection layer inside the perimeter, placed by room and traffic pattern, on homes across Sunnyvale and along the I-280 corridor.
Sensor placement
Where Sensors Go Matters More Than How Many
Contacts on the doors are where most systems stop, and it is the reason a surprising number of homes have an alarm that an intruder can walk around. Security sensor installation in Sunnyvale is about the layer behind the perimeter: motion detection on the paths somebody has to cross, acoustic detectors on the glass that is actually reachable, and contacts on the windows people assume nobody would bother with. Sunnyvale Home Security places these by walking the house and thinking about movement rather than by distributing hardware evenly. Two situations bring most of this work in. Either an existing system is generating repeated false alarms, which is nearly always a placement or sensitivity problem involving a pet, a heat source or a moving curtain, or a homeowner has worked out that their ground-floor slider and side windows have no coverage at all. The same panel can also carry water, smoke and carbon monoxide sensors, which is how a security system ends up catching a failing water heater.
What The Detection Layer Covers
Door and window contact fitting.
Recessed or surface magnetic contacts go on every opening worth covering, including the ground-floor windows and sliders that get skipped because they are awkward rather than because they are safe.
Slider and French door handling.
Sliding doors and French doors need contact placement and sometimes a secondary sensor to account for how they move and flex, which is a frequent weak point in the local housing stock.
Passive infrared motion placement.
PIR sensors are positioned to cover the routes an intruder must take, typically hallways and stair landings, rather than aimed across an entire open-plan room where coverage is thin at the edges.
Pet-immune sensor specification.
Where there are dogs or cats with run of the house, pet-tolerant units are specified and mounted at the right height, and we are honest about the weight threshold and what a large dog on furniture will still trigger.
Heat and airflow avoidance.
Motion sensors are kept away from vents, sunlit windows and fireplaces, because moving warm air across a PIR is one of the most common causes of a three-in-the-morning false alarm.
Acoustic glass break detectors.
Glass break units are placed by room acoustics and range, covering the reachable glass in a room from a single position rather than needing a sensor per pane.
Curtain and blind interference checks.
Window treatments that move on an air conditioning cycle get identified during placement, because a curtain drifting across a motion sensor will trip a system night after night.
Water and flood sensors.
Detectors at the water heater, under sinks, behind the washing machine and near any slab penetration report to the same panel, catching leaks while they are still cheap.
Smoke and carbon monoxide sensors.
Monitored life-safety sensors can share the panel, meaning a fire while the house is empty reaches the central station rather than just sounding into an empty hallway.
Zone naming and sensitivity tuning.
Every sensor is named on the panel and in the app so an alert tells you which opening tripped, and sensitivity is set on site with the household walking around normally.
Diagnosing, Placing, Tuning
Walking The Movement Paths
The technician walks the house thinking about how somebody would move through it, and where your household moves at night. He will look at glass reachability from the yard, curtain movement, vent positions and where pets sleep and travel. If you have an existing false-alarm problem, this is when the cause usually becomes obvious.
Placement Plan And Price
You get a plan naming each sensor, its room and what it is there to catch, with a flat written price. Where an existing panel is being expanded rather than replaced, that is confirmed here, along with whether your current panel has the zone capacity for what you want.
Install And Live Tuning
Fitting is usually a half-day for a typical sensor package. The tuning is the part that determines whether you keep arming the system: sensitivity gets set while the household walks through normally and the pets do what they do, and each zone is tested and named. False-alarm-prone spots get adjusted before the technician leaves rather than after a call at two in the morning.
Why These Sensors Stop Crying Wolf
False Alarms Traced To A Cause, Not Just Turned Down
Reducing sensitivity until a sensor stops reporting also stops it detecting anything. We find the actual cause, whether that is a vent, a sunlit patch of floor, a curtain or a cat with access to a bookshelf, and correct the placement. That is what makes a system people keep arming.
Pet Households Handled Realistically
Pet-immune is a specification with a weight limit, not a guarantee, and a large dog that climbs on furniture will defeat a badly positioned sensor regardless of the label. We place for your specific animals and tell you plainly where the remaining risk is instead of promising it away.
Glass And Sliders Actually Covered
Ground-floor sliders and side windows are the openings most commonly left off a quote because they are more work, and they are exactly the ones worth covering. Acoustic detectors are placed to cover a room's reachable glass properly, and slider contacts are fitted to allow for how those doors sit in their tracks.
Fix The Gaps Or Fix The False Alarms
If your system goes off for no reason, or you already suspect half your windows are not on it, both are solvable and neither usually needs a new panel. A walkthrough identifies what is uncovered and what is misplaced, and you get a written plan and a flat price for the corrections.
