A Nest security system can mean the discontinued Nest Secure alarm or a current setup built from Google Nest cameras, doorbells, and compatible alarm equipment. Nest Secure no longer works as an active security system, so a current camera-based setup commonly costs about $300-$900 upfront, with optional monitoring adding roughly $25-$60 per month.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Current Nest camera setup | $200 | $550 | $1,000 | Equipment only; depends on camera and doorbell count |
| ADT Self Setup equipment | $200 | $350 | $700 | Alarm equipment and selected add-ons |
| Optional professional monitoring | $25/month | $35/month | $60/month | Provider, plan, and contract terms vary |
| Legacy Nest Secure | $0 used | Not functional | Not functional | Google ended support in April 2026 |
What a working Nest security setup costs today
Google discontinued Nest Secure, its alarm system, and ended support on April 8, 2026. A used Nest Guard, Nest Detect sensor, or Nest Tag should not be treated as a functioning alarm purchase. The system cannot provide its former app-connected security service, even if the hardware powers on.
For current security, buyers generally price either a Google Nest camera-and-doorbell arrangement or an ADT Self Setup alarm system that works with selected Google Nest devices. A small camera setup may run $200-$400 before installation; a home with several cameras, a doorbell, and alarm sensors can reach $600-$1,200 or more. There is no currently supported Nest Secure package price because Nest Secure service has ended.
For planning purposes, the ranges below assume a typical U.S. home, standard retail equipment, ordinary installation access, and no major electrical work. Device prices and subscription requirements can change, and local sales tax is additional. Assumptions: equipment-only estimates unless a table specifies labor or monitoring.
Camera, doorbell, and alarm equipment in the quote
A quote is driven by the number and type of devices rather than by a single Nest-branded alarm kit. Indoor cameras usually cost less than outdoor models or floodlight cameras. Doorbells may require a compatible existing chime and wiring, while an alarm setup adds a hub, entry sensors, and possibly a keypad or motion sensor.
| Equipment or task | Materials | Labor | Delivery or disposal | Typical total |
|---|---|---|---|---|
| Nest indoor camera | $80-$120 each | $0-$100 | $0-$20 | $80-$240 |
| Nest outdoor camera | $150-$200 each | $0-$200 | $0-$25 | $150-$425 |
| Nest doorbell | $150-$200 | $0-$175 | $0-$25 | $150-$400 |
| ADT Self Setup alarm starter equipment | $200-$350 | $0-$150 | $0-$30 | $200-$530 |
| Extra contact or motion sensor | $25-$60 each | $0-$75 | $0-$10 | $25-$145 |
These are practical budgeting ranges, not guaranteed Google or ADT checkout prices. Camera placement that requires drilling, exterior cable routing, or a new doorbell transformer can add labor. For straightforward installation, an electrician or low-voltage installer may charge about $75-$150 per hour, often with a minimum service fee.
Equipment count and installation complexity explain most of the difference between a basic camera setup and a complete monitored system. Confirm whether a quote includes mounting, configuration, subscription service, and any required hub before comparing totals.
How camera count, wiring, and sensor coverage change the price
Each added camera increases equipment cost and may raise the cloud-storage subscription tier needed to retain recorded video. A single indoor camera and doorbell can keep equipment near $250-$400, while four cameras plus a doorbell often push equipment to $700-$1,000. Outdoor placement and floodlight features generally cost more than basic indoor coverage.
Wiring also matters. Battery cameras avoid running power cable and can be installed quickly, but batteries need periodic charging. Wired cameras need a nearby outlet or a cable run; concealed exterior wiring or a new outlet can add $150-$500 per location. A wired doorbell replacement may be inexpensive when the existing transformer and chime are compatible, but electrical corrections can add $100-$300.
Alarm coverage is priced by protected openings and zones. A basic package for one entry door and a few windows costs less than covering a home with 10 or more doors and windows. Adding five or more contact sensors can add roughly $125-$300 for equipment, before any installation. Count exterior doors, accessible ground-floor windows, and camera viewpoints before accepting a package price.
Home size affects the plan indirectly. A 1,500-square-foot house may need two or three carefully placed cameras; a 3,000-square-foot house with detached access points can need five or more. Large distance between the router and cameras may also require a Wi-Fi access point, typically $50-$200, or a wired network run.
DIY setup versus installer labor for Nest devices
Most Nest cameras and doorbells are designed for homeowner setup, and a basic installation may take 30-90 minutes per device, including app pairing and positioning. Self-installation can keep labor at $0, but the buyer still needs compatible Wi-Fi, a suitable power source, and a stable mounting surface.
Professional installation commonly costs $100-$250 for a simple doorbell or camera visit, and $300-$800 for multiple devices with more involved mounting or wiring. A larger job involving several exterior cable routes, new outlets, or difficult masonry can exceed $1,000. Ask whether the installer charges per device, by the hour, or a flat project fee; travel and minimum charges may apply.
ADT Self Setup is designed for homeowner installation, but buyers can ask about available installation service and current pricing. Professional monitoring is a separate recurring expense, not a one-time installation fee. Compare the installed total and the ongoing monthly charge separately. A low equipment quote can cost more over time if it requires a higher-priced monitoring or video plan.
Three household budgets for Nest-compatible security
These examples show how the same broad goal—seeing activity and receiving alerts—can lead to different budgets. The totals are planning estimates and exclude tax. They assume ordinary access and no unusual electrical, masonry, or network work.
| Scenario | Equipment details | Labor assumption | Upfront estimate | Monthly service |
|---|---|---|---|---|
| Apartment entry coverage | One doorbell camera and one indoor camera | DIY, 1-2 hours | $250-$400 | $0-$20 |
| Three-bedroom home | Doorbell, two outdoor cameras, alarm starter kit, three sensors | DIY or 3-5 installer hours | $600-$1,100 | $25-$60 |
| Large home with perimeter coverage | Doorbell, four cameras, hub, eight sensors, network extension | 5-10 installer hours | $1,100-$2,200 | $30-$60 |
In the three-bedroom example, three installer hours at $75-$150 per hour would add $225-$450 if labor is billed separately. Assumptions: midrange devices, standard U.S. labor rates, no major wiring work. A package discount or sale can reduce equipment totals, but it should be compared against the cost of buying only the devices actually needed.
ADT monitoring and Nest video subscriptions add recurring charges
Google Nest camera features and video history may require a paid Google Home subscription, depending on the device and desired recording history. Budget roughly $8-$15 per month for a basic video plan and around $15-$30 per month for more extensive camera coverage or longer history. Confirm current plan limits, supported devices, and whether a subscription is required for the specific alert or recording feature.
ADT Self Setup monitoring is a separate service choice. A reasonable planning range is about $25-$60 per month, depending on the monitoring tier, equipment, and terms available when ordering. Some packages or promotions may change the effective price, so examine the standard monthly rate, any contract length, cancellation charges, and what happens after a promotion ends.
Over five years, a $10 monthly video plan totals $600, while a $35 monthly monitoring plan totals $2,100. If both are needed, combined service charges could add roughly $2,400-$5,400 over five years. Include subscriptions in the ownership budget rather than comparing hardware prices alone. A self-monitored camera arrangement can avoid alarm monitoring fees, but it does not provide the same dispatch service as a monitored alarm.
Regional labor and wiring can shift installed prices
Equipment prices are broadly similar nationwide, but labor and travel costs vary. Dense metro areas and high-cost coastal markets can run about 10%-25% above typical national installation estimates. Smaller cities and suburban markets often fall near the middle, while remote rural locations may incur a 10%-30% travel or access premium if few installers serve the area.
Climate and building construction affect installation choices. Masonry, stucco, thick exterior insulation, and difficult rooflines can add $100-$400 per camera location compared with simple wood siding. In cold regions, battery-camera charging and placement should be considered; in hot or humid areas, equipment must be rated for its exposure and installed away from direct weather where appropriate.
Request a written quote that separates equipment, labor, travel, wiring, and any recurring plan. If one estimate is substantially higher, ask whether it includes a new outlet, transformer, network extender, or a longer video-history subscription. Comparing identical device counts and service terms makes regional quotes much easier to judge.
Lower the Nest security budget without losing useful coverage
Start with the security gaps that matter most: entry doors, ground-floor access, and areas where packages are left. Avoid buying one camera for every room if a better-positioned device can cover multiple approaches. Check Wi-Fi strength before ordering outdoor equipment; a $50-$200 network improvement can be cheaper than repeated camera troubleshooting or a costly cable run.
Choose battery models when wiring would require extensive labor, but compare the convenience of charging with the cost of a nearby power source. Reuse a compatible doorbell transformer or existing cable only after confirming the device requirements. Buy additional sensors after testing the starter kit’s coverage rather than ordering a large bundle based on unused openings.
Compare at least two itemized quotes and ask whether setup, mounting, app configuration, and removal of old equipment are included. Schedule nonurgent work during periods when installers have availability, and ask about bundle pricing only when every included device is useful. The largest savings usually come from controlling device count, wiring scope, and monthly service rather than choosing the cheapest camera alone.
Do not buy used Nest Secure hardware as a lower-cost substitute: it is discontinued and unsupported. For a functional alarm, compare current ADT Self Setup equipment and monitoring with other supported alarm providers. For video alerts without professional dispatch, price a smaller Nest camera-and-doorbell setup and its subscription separately.
