Using Dual Video / MultiCam Recording

Dual Video is a capture mode that records from two iPhone cameras at the same time — typically the rear wide-angle camera for spatial context and the rear telephoto for damage detail. The result is two synchronized video streams from a single recording session, which together tell a more complete story than either recording alone.

Device requirements

Dual Video uses Apple's AVCaptureMultiCamSession framework, which is available on:

If your device doesn't support MultiCam, the Dual Video option won't appear in the app.

When to use Dual Video

Dual Video is most valuable when you need to document both the damage and its location in the same recording session, without switching between camera modes.

Best use cases:

• Roof damage documentation — wide camera shows the overall roof plane and coverage pattern; telephoto captures granule loss, impact marks, or lifted shingles in detail
• Exterior siding damage — wide establishes the full elevation; telephoto shows crack detail, impact points, or delamination
• Interior water damage with extensive spread — wide shows the affected area; telephoto documents specific staining boundaries or mold growth

When standard video is sufficient:

• Single-room interior inspections where the damage is close-range
• Situations where only one camera angle adds value
• Devices that don't support MultiCam

Starting a Dual Video session

1. Open the job in the iOS app and go to Capture
2. Tap + Add Media
3. Select Dual Video
4. Assign an area
5. Tap Record — both cameras begin recording simultaneously
6. Tap Stop to end both recordings

The two streams are saved as separate video files, both tagged to the same area, with matching timestamps so they can be reviewed side by side.

Viewing Dual Video recordings

In the job's Capture tab on the web dashboard, Dual Video recordings are shown as a paired set — the two streams appear together with a visual indicator that they're linked. Play them side by side or individually.

Battery and storage impact

Recording from two cameras simultaneously uses more battery and generates larger files than standard video.

For long inspection sessions using Dual Video:

• Keep your iPhone charged above 50% before starting
• Consider a portable battery pack for extended fieldwork
• Upload over WiFi at the end of the session for speed

Frequently asked questions

Can I choose which two cameras to use? The current implementation uses the rear wide + rear telephoto combination, which is the most useful pairing for property inspection. Camera selection options are on the roadmap.

My iPhone XS isn't showing the Dual Video option — why? Make sure you're running iOS 17.0 or later. Also verify the Estimatics app is updated to the latest version from the App Store.

Does Dual Video work with Dual Video markup? Yes — both streams from a Dual Video recording support frame-level markup on the web dashboard. Each stream is marked up independently.

Can I use Dual Video offline? Yes. Both streams are recorded locally and sync when you reconnect, exactly like standard video.
