Galois P4 vs Matterport Pro3
Two professional LiDAR cameras—and two very different ways to capture, host, and deliver spatial work.
Quick verdict
Choose the system, not just the camera.
Galois P4 is the more compelling research shortlist for teams that prioritize very high-resolution visual output, denser vendor-stated spatial data, on-device capture options, and project-based platform spending.
Matterport Pro3 is the safer operational choice for teams already delivering through Matterport—or for clients who specifically expect its viewer, integrations, Active Spaces model, and established ecosystem.
At a glance
Manufacturer-stated specifications and current public prices, checked September 2026.
| Comparison | Galois P4 | Matterport Pro3 |
|---|---|---|
| Comparable kit price | $7,499 — P4 Standard Kit | $4,495 — Pro3 Performance Kit |
| Camera-only price | Not separately listed | $3,995 — Pro3 camera |
| Capture time | 16 sec per scan point | Under 20 sec per scan |

| Maximum listed range | 0.1–100m at 90% reflectivity | Up to 100m in E57; processed models use 20m depth |
| Weight | 2.6kg / 5.73lb, battery included | 2.2kg / 4.85lb |
| Field control | On-device touchscreen workflow listed by Realsee | Matterport Capture app on iOS or Android |
| Platform model | Credits; active hosting charged by project/month | Subscription; capacity based on Active Spaces |
| Best fit | Output-led teams prioritizing visual detail and variable project volume | Teams prioritizing ecosystem familiarity and standardized delivery |
Specifications are not a substitute for matched field testing. “Stated accuracy” uses each manufacturer's own test distance and wording, so the figures are not directly equivalent laboratory results.
The decision is bigger than the camera
Both systems capture a space. The bigger difference appears after the scan.

Which workflow fits your work?
Property media teams
Shortlist P4 when premium visual detail and a broader menu of spatial outputs are central to the service you sell.
Shortlist Pro3 when “Matterport” is already part of the client brief and fast, familiar delivery matters more than changing platforms.
Commercial real estate portfolios
P4 may fit project-based providers that want expenses to follow active client work.
Pro3 may fit teams already managing repeat properties, users and integrations through Active Spaces.
AEC and documentation
P4 deserves evaluation for its listed point density, accuracy and export-oriented positioning.
Pro3 deserves evaluation where Matterport add-ons and existing Autodesk, Procore or enterprise workflows are already approved.
Pros and limitations
Galois P4
What looks strong
- 24K, up-to-300MP visual output is compelling on paper.
- Faster listed scan cycle and denser listed point capture.
- On-device capture and co-capture could help complex fieldwork.
- Credits may align costs with project-based delivery.
What needs scrutiny
- Substantially higher upfront kit price.
- Smaller global ecosystem and less client familiarity.
- Export quality, support and data portability need hands-on validation.
- Many differentiators currently rely on vendor-reported information.
Matterport Pro3
What looks strong
- Lower upfront price for a comparable professional kit.
- Mature, widely recognized capture and viewing ecosystem.
- Established integrations, service partners and client familiarity.
- Consistent end-to-end workflow for standardized teams.
What needs scrutiny
- Pro3 uploads require a Professional plan or higher.
- Active-space limits and add-ons shape ongoing cost.
- Capture depends on the mobile Capture app.
- Switching platforms later may disrupt established delivery processes.
