Nest vs ADT 2026: Google’s Smart Cameras vs America’s Oldest Security Company — Full Comparison
Google Nest and ADT are an interesting pair to compare — they were once partners (ADT sold Nest products), but they serve fundamentally different needs. Nest is a camera-first smart home ecosystem without a real alarm system, while ADT is a traditional security company with 150+ years of monitoring experience.
Which one actually keeps your home safer? We compared everything: hardware, monitoring, cameras, costs, and the smart home experience.
| Feature | Google Nest | ADT |
|---|---|---|
| System type | Camera ecosystem (no alarm) | Full alarm system + cameras |
| Professional monitoring | ❌ No standalone monitoring | ✅ 24/7 (6 US monitoring centers) |
| Monthly cost | $0 (cameras) / $8-$15 (Nest Aware) | $24.99-$49.99 |
| Cameras | Excellent (Indoor, Outdoor, Doorbell, Floodlight) | Good (resells Google Nest cameras) |
| Alarm sensors | ❌ None | ✅ Full range (doors, windows, motion, glass break) |
| Installation | DIY | Professional or DIY Self Setup |
| Contract | None | Month-to-month available (Self Setup) |
| Smart home | Google Home ecosystem | Google Nest devices + Z-Wave |
| HomeKit support | ❌ | ❌ |
| Battery backup | Some cameras (battery models) | ✅ 24-hour backup |
| Cellular backup | ❌ | ✅ (included with monitoring) |
| Best for | Smart home enthusiasts, renters wanting cameras | Homeowners wanting full security with pro monitoring |
The ADT + Nest Partnership (And Why It Matters)
ADT and Google partnered in 2020, with Google investing $450 million in ADT. The result? ADT now sells and installs Google Nest cameras as part of their professional security packages. This means:
- ADT customers get Nest cameras (the same hardware Google sells directly)
- ADT’s monitoring center can respond to Nest camera alerts
- You get Google’s camera AI + ADT’s professional monitoring in one package
So in some ways, choosing ADT now means you’re also choosing Nest cameras. The question is whether you need ADT’s monitoring and alarm system on top of the cameras.
Google Nest Camera Pricing
| Product | Price | Key Feature |
|---|---|---|
| Nest Cam (indoor, wired) | $100 | 1080p, person/pet/vehicle detection |
| Nest Cam (outdoor/indoor, battery) | $180 | Weather-resistant, wire-free |
| Nest Cam with Floodlight | $280 | 2400 lumens, HDR, intelligent alerts |
| Nest Doorbell (wired) | $180 | HDR, 24/7 recording, package detection |
| Nest Doorbell (battery) | $180 | Wire-free, 3-hour event history (free) |
Nest Aware Plans
| Plan | Monthly | Annual | Features |
|---|---|---|---|
| Nest Aware | $8.00 | $80 | 30-day event history, familiar face detection |
| Nest Aware Plus | $15.00 | $150 | 60-day event history, 10-day 24/7 recording |
ADT Pricing
| Item | Cost | Notes |
|---|---|---|
| Starter Equipment (Self Setup) | From $269 | Base station, keypad, sensors |
| Professional Installation | $99 | Technician sets up everything |
| Secure Monitoring | $24.99/mo | No video, alarm monitoring only |
| Complete Monitoring | $49.99/mo | Full monitoring + video + smart home |
3-Year Total Cost Comparison
| Setup | Hardware | Monthly | 3-Year Total |
|---|---|---|---|
| Nest 3-cam (no subscription) | $460 | $0 | $460 |
| Nest 3-cam + doorbell + Aware | $640 | $8 | $928 |
| Nest 3-cam + doorbell + Aware Plus | $640 | $15 | $1,180 |
| ADT Self Setup (Secure, no video) | $269 | $25 | $1,169 |
| ADT Self Setup (Complete) | $269 | $50 | $2,069 |
| ADT Pro Install (Complete) | $368 | $50 | $2,168 |
| Abode Smart Security Kit + Cam 2 | $299 | $6 | $515 |
The real story: Nest gives you great cameras for cheap — but zero security system. ADT gives you a real alarm system but at $1,169-$2,168 over 3 years. Abode at $515 gives you both cameras AND an alarm system for less than either option alone.
Security Capabilities
| Capability | Google Nest | ADT |
|---|---|---|
| Intrusion detection (doors/windows) | ❌ | ✅ |
| Motion sensors | Camera-based only | ✅ Dedicated sensors |
| Glass break detection | ❌ | ✅ |
| Smoke/CO monitoring | Nest Protect (self-only) | ✅ Monitored |
| Water leak detection | ❌ | ✅ |
| Panic button | ❌ | ✅ |
| Professional monitoring | ❌ | ✅ (6 centers, 24/7) |
| Police/fire dispatch | ❌ | ✅ |
| Cellular backup | ❌ | ✅ |
| Siren | ❌ | ✅ (105dB) |
This is Nest’s fundamental weakness. Google Nest cameras can detect and record intruders, but they can’t prevent break-ins or dispatch help. Nest is a surveillance system, not a security system. ADT (and Abode) are actual security systems.
Camera Quality Comparison
| Feature | Google Nest | ADT (Nest cameras) |
|---|---|---|
| Resolution | 1080p (all models) | 1080p (same Nest hardware) |
| AI detection | Person, pet, vehicle, package | Same (Nest AI) |
| Night vision | HDR, night vision | Same |
| Two-way audio | ✅ | ✅ |
| Cloud storage (free) | 3 hours event history | Included with Complete plan |
| 24/7 recording | Nest Aware Plus ($15/mo) | Complete plan ($49.99/mo) |
Since ADT now uses Nest cameras, the hardware is identical. The difference is what’s behind the cameras — ADT adds professional monitoring, so if a camera detects something, a monitoring agent can verify and dispatch help.
Smart Home Integration
| Platform | Google Nest | ADT | Abode |
|---|---|---|---|
| Google Home | ✅ (native) | ✅ (via Nest) | ✅ |
| Amazon Alexa | Limited | Limited | ✅ |
| Apple HomeKit | ❌ | ❌ | ✅ (full system) |
| Z-Wave | ❌ | ✅ | ✅ |
| Matter | ✅ | Coming | Coming |
| Thread | ✅ (Nest devices) | Via Nest | Coming |
Both Nest and ADT are Google-centric. Neither supports HomeKit. If you’re an Apple household, Abode is the only security system with full HomeKit support, including HomeKit Secure Video via the Abode Cam 2.
Who Should Choose Google Nest?
- You only need cameras, not a full alarm system
- You’re deep in the Google Home ecosystem
- You want excellent AI detection (person, pet, vehicle, package)
- You’re a renter who wants easy, wireless camera setup
- You don’t need professional monitoring or police dispatch
Who Should Choose ADT?
- You want professional installation and don’t want to DIY
- You need 24/7 professional monitoring with police/fire dispatch
- You want 150+ years of security experience backing your system
- You want Nest cameras PLUS a full alarm system
- You want cellular and battery backup for power/internet outages
Consider Abode Instead
Before committing to either Nest or ADT, Abode offers the best of both worlds:
| Feature | Google Nest | ADT | Abode |
|---|---|---|---|
| Full alarm system | ❌ | ✅ | ✅ |
| Quality cameras | ✅ | ✅ (Nest) | ✅ (Cam 2) |
| Free plan available | ✅ (cameras only) | ❌ | ✅ |
| Pro monitoring | ❌ | $24.99-$49.99/mo | $20/mo |
| Cellular backup | ❌ | $24.99+/mo | $6/mo (Connect) |
| HomeKit | ❌ | ❌ | ✅ |
| HomeKit Secure Video | ❌ | ❌ | ✅ |
| No contract | ✅ | Varies | ✅ |
| 3-year cost | $460-$1,180 | $1,169-$2,168 | $515 |
Abode’s Smart Security Kit gives you cameras + alarm + optional monitoring starting at $6/month — dramatically cheaper than ADT, with better privacy (HomeKit Secure Video), and broader smart home support than either Nest or ADT. See all plans →
FAQ
Does Google Nest have a security system?
No. Google discontinued the Nest Secure alarm system in 2020. Nest now only offers cameras and doorbells. For a Google-compatible alarm system, consider Abode which works with Google Home and has a full alarm system.
Does ADT still use Nest cameras?
Yes. ADT and Google partnered in 2020, and ADT installs Nest cameras as part of their security packages. You get the same Nest hardware with ADT’s monitoring layer on top.
Can I add Nest cameras to a non-ADT security system?
Nest cameras work independently and with Google Home routines. While they don’t directly integrate with most third-party alarm systems, you can use them alongside any DIY system like Abode.
Is ADT worth the monthly cost?
ADT’s monitoring is reliable but expensive ($25-50/mo). For most homeowners, Abode offers equivalent security at $6/mo (Connect) or $20/mo (Pro with 24/7 monitoring) — saving $60-360/year.
Which is better for apartments?
Nest cameras (no drilling, no subscription needed). For apartment renters who want a full alarm system too, Abode’s wireless kit is ideal — no drilling, no contract.
Does either work with Apple HomeKit?
Neither Nest nor ADT supports HomeKit. Abode is the only security system with full HomeKit integration, including HomeKit Secure Video for end-to-end encrypted camera footage.
