Intrusion Detection & Alarm Systems
When someone tests your building, the building answers.
An intrusion system is your after-hours workforce: door and window sensors, motion detection, glassbreak protection, and a monitored panel that calls for help the moment something's wrong.
Intrusion Detection & Alarms in Sacramento
We design and install commercial intrusion detection systems sized to the real risks of your facility — entry points, glass storefronts, roof hatches, interior high-value rooms, and yards. Systems are built on commercial-grade panels with cellular and IP communicators, so the alarm still reports even if a phone line or internet connection is cut.
Monitoring is handled by a UL-listed central station with 24/7 dispatch, open/close reporting, and mobile app control for arming, disarming, and event history. We also take over and modernize existing alarm panels, and we integrate intrusion with video surveillance and access control so alarms come with eyes and context.
Detection & alarm systems we install
Commercial alarm panels & keypads
Commercial-grade control panels with partitioning, user codes, and schedules — armed from a keypad, fob, or phone app.
Door & window contacts
Every exterior opening supervised, including overhead doors, roof hatches, and gates — the first line of detection.
Motion & glassbreak sensors
Dual-technology motion detection and acoustic glassbreak sensors placed to catch intruders without false-alarming on daily life.
24/7 central-station monitoring
UL-listed monitoring with live operators, verified dispatch, and notification chains that reach the right people every time.
Cellular & IP communicators
Dual-path alarm reporting that doesn't depend on a phone line — resilient against cut lines and internet outages.
Panic, duress & holdup buttons
Silent alarms at reception desks, cash-handling points, and public counters for staff-initiated emergency response.
Environmental monitoring
Water/flood, temperature, and power-loss sensors that protect server rooms, inventory, and equipment from non-criminal disasters.
Takeovers & modernization
Most existing alarm panels and wired sensors can be taken over, upgraded, and re-monitored — often at a fraction of replacement cost.
The Scarlett Standard
What 'done right' means here
Designed against false alarms
Sensor selection and placement, entry delays, and user training that keep false dispatches — and city fines — to a minimum.
Licensed alarm work
California alarm systems require a BSIS Alarm Company Operator license in addition to the CSLB C-7 — we operate fully licensed.
Integrated response
Alarm events can pull up cameras, lock doors, and notify your team simultaneously — detection with context, not just noise.
Good Questions
Intrusion Detection FAQs
Do I need an alarm permit in Sacramento?
Most Sacramento-area jurisdictions require an alarm permit for monitored systems, and unpermitted false alarms carry higher fines. We walk you through the permit requirements for your specific city as part of the install.
Can you monitor an alarm system another company installed?
Usually, yes. Most commercial panels can be taken over, reprogrammed, and connected to our UL-listed central station — often with upgraded cellular communicators — without replacing the sensors already on your walls.
What happens when the alarm goes off?
The panel signals the central station within seconds over cellular/IP. Live operators follow your response plan — verify, notify your contact list, and dispatch police if warranted. You also get instant push notifications with event details.
