Which Security Camera System Is Right for Your Home or Business?
When choosing a surveillance system, one of the most common comparisons we hear at St. Louis Alarm Company is between Alarm.com cameras and Reolink cameras.
Both brands have strong reputations — but they serve very different purposes depending on your goals.
If you’re protecting your home or business in St. Louis, St. Charles, O’Fallon, or surrounding areas, here’s a real-world breakdown to help you decide.
🔐 Alarm.com Cameras
(Designed for Integrated, Professionally Monitored Security Systems)
Where Alarm.com Shines
- Seamless Integration with Your Alarm System
Alarm.com cameras are designed to work directly with your security panel. That means:
- Video clips tied to alarm events
- Cameras that record when doors open or motion trips
- Arming/disarming triggers video capture
- Single app control for alarm + video + automation
If you already have an Alarm.com security system, this integration is a major advantage.
- AI Deterrence & Smart Analytics
Alarm.com focuses on intelligent protection, not just recording.
Features include:
- Person detection
- Vehicle detection
- Package detection
- Familiar face recognition
- Active deterrence (lights, audio warnings)
- Smart video alerts
Instead of just reviewing footage after something happens, you’re notified in real time — and in some cases, intruders are deterred before damage occurs.
- Remote Video Monitoring (RVM)
This is where Alarm.com truly separates itself.
With professional monitoring:
- A central station can view live video during alarms
- Operators verify threats
- Faster police dispatch in many cases
- Reduced false alarms
For commercial properties especially, verified response can dramatically improve outcomes.
- Cloud Storage Model
Alarm.com primarily stores video clips in the cloud.
They currently emphasize:
- 1080p and 4MP cameras
- Intelligent compression
- Efficient clip-based storage
They do not heavily focus on 4K resolution (at least not currently), and there’s a reason:
4K video consumes:
- Massive bandwidth
- Large storage space
- Higher cloud costs
For many applications, 1080p is more than sufficient.
Seeing the hair follicles in an intruder’s nose doesn’t protect your property better.
Identifying that a person is there — and responding quickly — does.
- Commercial Stream Video Recorder (CSR) – 24/7 Onsite Recording
One common misconception is that Alarm.com is cloud-only.
For commercial clients, Alarm.com offers a Commercial Stream Video Recorder (CSR).
The CSR provides:
- 24/7 continuous onsite recording
- Local hard drive storage
- Hybrid cloud + local functionality
- Remote access through the Alarm.com app
- Integration with analytics and monitoring
This means commercial properties can have:
- Continuous recording like an NVR system
- PLUS cloud clips
- PLUS alarm integration
- PLUS remote monitoring
It combines the best of both worlds.
Best For:
- Homes with monitored alarm systems
- Businesses needing verified response
- Customers who want AI deterrence
- Commercial properties needing 24/7 onsite recording
- Those who prefer professional installation and support
- Customers who want everything in one app
📷 Reolink Cameras
(High Resolution, DIY-Friendly, Local Storage Focused)
Where Reolink Excels
- High Resolution Options (Including 4K)
Reolink is known for offering:
- 4MP
- 8MP (4K)
- Even higher resolution models
If you’re covering:
- Large parking lots
- Warehouses
- Large properties
- Wide open commercial spaces
Higher resolution can absolutely pay off.
More pixels = more digital zoom clarity.
- Local Storage (NVR-Based Systems)
Reolink typically uses:
- NVR systems
- Local hard drives
- SD card recording
Benefits:
- No mandatory cloud fees
- Full continuous recording
- Large storage capacities
This makes them attractive for budget-conscious users who want full-time recording without recurring costs.
- DIY Friendly
Reolink is often:
- Purchased online
- Self-installed
- Configured without a monitoring company
That’s great for tech-savvy homeowners who want control and lower upfront investment.
Best For:
- Large area coverage needing 4K clarity
- Users comfortable managing their own system
- Budget-focused installations
- Continuous 24/7 recording needs

Resolution: How Much Do You Really Need?
Here’s the honest truth:
For many residential applications, 1080p is absolutely fine.
If you’re covering:
- Front door
- Driveway
- Backyard
- Entry points
1080p will identify a person clearly enough for response and evidence.
But…
If you’re covering:
- Large commercial lots
- Wide warehouse interiors
- Long-range views
Higher resolution makes a real difference.
It depends entirely on your application.
Final Recommendation
If you already use Alarm.com for your alarm system, the integrated experience, AI deterrence, remote monitoring, and CSR recording options make it extremely hard to beat.
If your priority is maximum resolution and local recording without recurring costs, Reolink can be a solid option.
At the end of the day:
Go with what you know and love — unless you want features Alarm.com offers that Reolink doesn’t.
