Where to find them
Office
System types this installer covers
Plain-English notes on each capability this listing surfaces, plus a 7-row source-attribution matrix so you can see where each signal came from.
-
01
What CCTV install really involves
Most modern jobs are IP cameras + an NVR (network video recorder), not the old DVR + coax setup. A solid first walk-through covers angle and lens choice (wide for entries, telephoto for the driveway), PoE switch sizing, NVR storage tiers (rolling 7 vs 30 vs 90 days), and whether you'll watch via app, on-site monitor, or both.
-
02
What 24/7 monitoring buys you
A monitored alarm calls a central station within seconds of trip — they verify, then dispatch police or fire on your behalf. Worth confirming who actually does the monitoring (in-house vs partner like Rapid Response or Brinks), the verification protocol (audio/video before dispatch), and the monthly fee plus contract length.
-
03
What smart-home integration covers
Means the security panel talks to platforms you already use — Z-Wave / Zigbee for door locks and lights, Alexa or Google Home for voice, sometimes Apple HomeKit. Ask which ecosystem they support natively (vs needing a third-party hub), and whether arming/disarming via app is included or an add-on subscription.
-
04
What access-control systems involve
Keypads, card readers, and electronic locks — common in small offices, multi-tenant buildings, and any facility where you need to revoke a single user without rekeying. Ask about hardware compatibility (HID, Mercury, ZKTeco), whether the system is hosted in the cloud or on-premise, and what audit trails it generates.
-
05
What a residential install typically looks like
A standard home job runs 4-8 hours: alarm panel, door/window contacts, motion sensors, glass-break, optionally cameras and smart locks. The pricing model varies — some installers sell equipment, others lease it as part of a monitoring contract. Confirm equipment ownership before signing.
-
06
What a commercial install differs in
Commercial jobs use higher-grade panels (UL-listed), often integrate with fire / sprinkler systems, and may need a low-voltage permit. Multi-door access control, business-grade NVR storage, and integration with HR systems for badge provisioning are common asks. Expect more drawing review and longer install windows than a home job.

PRE-SIGN CHECKLIST
Before you sign a contract
Four things to nail down before equipment goes on your wall — what to ask for, where DIY makes sense, the rule that applies in your state, and the questions every install touches.
1 / Ask for these
- State security-installer license number (so you can verify on the state board website)
- Proof of liability insurance (a million-dollar minimum is normal)
- Brand and model of the panel + cameras they'll install (not just "ours")
- Who actually does the monitoring (in-house vs Rapid Response / Brinks / etc.)
- Whether equipment is sold to you or leased through the monitoring contract
- Contract length, monthly fee, and the early-termination penalty if you cancel
2 / Where DIY can make sense
-
Pure DIY
Ring, Nest Aware, Wyze, SimpliSafe — buy the kit, install it yourself, optionally pay for self-monitoring. Best for renters, small homes, or as a starter setup.
-
DIY install + pro monitor
SimpliSafe Interactive, Cove, abode — you do the install but pay a small monthly fee for a central station. Bridge between DIY and full-service.
-
Pro install + pro monitor
Listings on this directory mostly fall here. ADT, Vivint, local installers like this one. Higher equipment + monthly cost, but they own the install warranty and the monitoring relationship.
-
Full integrator
For commercial sites: card-access doors, fire panels, IT-room monitoring, often integrated with HR provisioning. Specialized firms only — usually different from the residential-focused installers.
3 / The rule in CA
CA requires anyone installing burglar alarms or low-voltage security wiring to hold a state license — usually issued by the state Department of Consumer Affairs, Bureau of Security & Investigative Services, or equivalent. Verify the license number on the state board website before signing. Cities also typically require an alarm-system permit and may fine repeated false alarms (anywhere from $50 to $500 per incident after the first two or three).
4 / Common questions
What does a typical home security install cost?
Equipment + install for a basic 4-sensor alarm panel runs $400-800; cameras add $150-300 each; smart locks $200-400. Monitoring is usually $30-50/month with a 24- or 36-month contract. DIY kits like SimpliSafe start around $250 with optional $15-30/month monitoring.
Do I own the equipment or lease it?
Depends on the installer. Pro installers often lease equipment as part of the monitoring contract — if you cancel, the gear stops working with their app. Buying outright costs more upfront but lets you switch monitoring providers later. Always ask before signing.
How fast does a monitored alarm get a response?
A UL-listed central station calls within 30-60 seconds of a trip to verify, then dispatches police or fire if needed. Verification helps cut false-alarm fines. Average dispatch time is 90-120 seconds. Some systems use audio/video verification before any call to police.
What's the difference between a security installer and a fire-alarm installer?
Fire alarms are regulated under separate state and city codes — usually require a different license and inspection trail. Some larger installers do both; many residential security shops don't. If you need an integrated fire + security panel for a small business, ask specifically.
Will my system work during a power outage or internet drop?
A properly installed alarm panel has a battery backup (good for 24+ hours) and a cell radio for monitoring (so it doesn't depend on home internet). Cameras and smart locks usually need power and internet. Confirm both — battery + cellular — before signing.
Do I need a permit to install a home security system?
Many cities require an alarm-system permit before the monitoring company can dispatch on your behalf. Costs are usually $25-100/year, and false-alarm fines kick in after 2-3 trips. The installer typically files the permit on your behalf as part of activation.
Does Dempsey Alarms LLC install CCTV cameras?
CCTV / camera install appears on this listing. Confirm the brand of NVR they use, whether storage is on-prem or cloud, and how many days of footage you'll have rolling. Cloud storage often adds a per-camera monthly fee.
Can Dempsey Alarms LLC handle commercial-grade installs?
Commercial work appears on this listing. For multi-door access control, fire-panel integration, or anything requiring a low-voltage permit, ask about UL-listing of the central station and whether they pull permits in your jurisdiction.
