Effective scan guidelines

The quality of your scan determines the quality of everything that comes from it - the 360° image quality, processing time, scan and issue locations, and AI progress tracking.

Before you start

Before hitting Start Recording, the Oculo mobile app shows you a pre-scan health check. Make sure all three are green:

🔋  Camera battery

📱  Mobile device battery

🗄️  Camera storage space

Shown in the app before you start. Charge fully before going on site.

A long scan on a low battery phone risks losing your session mid-walk.

Shown in the app. Delete old published scans from the camera if space is low.

 

Also check before you leave:

  • Camera lenses are clean - wipe with the microfibre cloth. Even a fingerprint will affect image quality
  • Use the Oculo mobile app - this ensures the right settings are used by the camera
  • You have a high level plan for the floors you’re covering today

 

How to carry the camera

How you carry the camera is one of the biggest factors in scan quality. The camera needs a clear, unobstructed 360° view at all times.

The right way

  • Hard hat mount (recommended for most internal scanning) - attach the camera to the mount on top of your hard hat. This keeps your hands free, the camera stable, and above head height.
  • Selfie stick, camera held above head height - extend the selfie stick and hold the camera above your head. Better for low-clearance areas like scaffold, and for certain mobile lighting systems (see Scan Lighting article).

Why above head height?

Holding the camera above head height gives it the clearest possible view of the space. It reduces the chance of your body, arms, or equipment blocking parts of the 360° image.

On scaffold or external elevations, use a selfie stick and hold the camera in the hand closest to the building - this way your body faces outward and doesn’t block the facade

 

What not to do

  • Don’t hold the camera directly in your hand at waist or chest height - your body will block a significant portion of the 360° view, reduce coverage quality, and impact processing (possibly resulting in a cancelled scan)

 

The 8 guidelines

Follow these guidelines for every scan. 

1

📍  Set your start location accurately

Why: Oculo maps your entire scan to the floor plan using your start point as the anchor. An inaccurate start location shifts the whole scan on the plan.

  1. When prompted, pinpoint your exact position on the floor plan before the recording begins
  2. Zoom in on the plan and place the pin precisely - don’t just drop it approximately in the right area
  3. Choose a recognisable, fixed reference point (e.g. a doorway, stairwell, or column) rather than an open space
  4. If you’re scanning multiple floors, select the correct floor from the dropdown before placing your pin

⚠️  An inaccurate start location is the most common cause of a scan appearing misaligned on the floor plan. Take 10 extra seconds here.

2

💡  Check your lighting before you walk

Why: 360° cameras need even, diffuse light across the whole space. Poor lighting causes grainy scenes, blurring, and location tracking problems.

  1. Scan during daylight hours where possible - avoid dusk and dawn when light levels are dropping
  2. Turn on all available static lighting in the areas you’re scanning - overhead lights, strip lighting, temporary site lighting
  3. For dark areas (basements, plant rooms, areas without natural light), use a diffuse lighting attachment such as a Bushman Halo on a selfie stick or a Hard Hat Halo.
  4. Never use a head torch, beam torch, or your phone’s flash - any directional beam causes hotspots, grainy images, and processing errors

⚠️  If an area is too dark to scan well today, note it and return when lighting conditions improve. A dark scan is worse than no scan - it can cause processing failures.

3

🚶  Walk like you’re carrying a cup of coffee

Why: The camera captures a frame every 0.5 seconds in Timelapse mode. Move too fast and you’ll have gaps in coverage. Move too erratically and the image quality drops.

  1. Walk at a calm, steady pace - think of a relaxed stroll, not a quick site inspection march
  2. Keep your movements smooth and predictable - avoid sudden turns, stops, or jerky movements
  3. You can look around naturally, but avoid fast head movements if you’re hard hat mounting
  4. Pause for a second or two in the centre of smaller rooms to ensure full coverage

4

🔄  Walk around the perimeter of every room

Why: Walking through the centre of a room leaves the corners and edges under-captured. Walking the perimeter gives comprehensive coverage of all surfaces.

  1. Walk around the perimeter of each room, staying approximately 1-2 metres from the walls
  2. For smaller rooms, walk to the centre then pause briefly
  3. Don’t skip rooms - including smaller spaces like toilets, plant rooms, stairwells, and storage areas
  4. For large rooms, walk a snake-like path to ensure coverage throughout

⚠️  Missing rooms is one of the most common feedback points from office-based teams reviewing a scan. If it’s on the floor plan, scan it.

5

⬆️  Use stairs between floors - not lifts or hoists

Why: Oculo tracks your movement continuously to stitch the scan across floors. A lift or hoist breaks that spatial continuity and causes the scan to fail across floors.

  1. Always use the stairs when moving between floors during a scan
  2. You can ride a hoist or lift to the top floor before starting - then walk down the stairs, scanning each floor as you go
  3. If you absolutely must use a lift during a scan, stop the recording before entering it. Start a new scan from your current location when you exit
  4. Update your start location accurately when beginning a new scan mid-site

⚠️  Using a lift mid-scan without stopping will cause processing delays, and possible floor allocation problems.

6

📹  Record everything in one continuous scan

Why: Oculo works best with one long, continuous recording per site visit. Multiple short scans mean manual stitching and gaps in the coverage timeline.

  1. Start recording at the beginning of your site walk and stop only when you’ve finished
  2. You can cover multiple floors in a single recording - Oculo handles the transitions via the stairs
  3. Pausing to talk to someone on site is fine - the recording continues but no audio is captured in Timelapse mode
  4. If something forces you to stop mid-scan (e.g. you need to use a lift, leave the site, or deal with an issue), stop the recording properly, then start a new one when you resume from where you left off

7

🧹  Camera care and maintenance

Why: A dirty lens or a scratch may be invisible to the eye but immediately obvious in the 360° output. Dust, fingerprints, and debris cause blurring that affects both image quality and AI accuracy.

  1. Wipe both lenses with the microfibre cloth before every scan — make it part of your pre-scan routine
  2. Give the lenses a quick clean after transporting the camera across site or in a bag
  3. Store the camera with the lens cover on when not in use
  4. If the lenses look scratched or damaged, and your outputs are affected consider a replacement lens (X5 camera only) or a replacement camera

 

How often to scan

The more frequently you scan, the more useful Oculo becomes - both for 360° documentation and for progress tracking.

Recommended cadence

Aim for one comprehensive scan per week as a minimum. A weekly scan gives your team an accurate, up-to-date record of progress and gives the AI enough data to track trends and identify bottlenecks.

For fast-moving phases or compliance-sensitive work (e.g. pre-pour inspections, cladding installation, fire stopping), scan more frequently - daily if the work warrants it.

A scan takes roughly the same time as a normal site walk. Build it into your existing routine rather than treating it as a separate task.

 

Scanning outdoors

Scanning outdoors follows the same principles as internal scanning, with a few adjustments for the environment.

  • Ensure that you have provided a site plan so that you can select an accurate start and end point, and so the site plan can be used for processing outdoor sections of your scan
  • Choose a good reference point on the site plan as a starting location, one where you can be sure that it is accurate (eg a site entrance, or an existing building - not in the middle of a large open area)
  • Try to avoid rain - the cameras are water resistant, but the lenses will get covered in raindrops affecting your image quality. If they do get rained on, try to dry them off regularly, and ensure they are dried off before scanning internals.

 

Scanning scaffold and external elevations

Scaffold and external areas again follow the sameprinciples, with a few adjustments for the environment.

  • Use a selfie stick rather than a hard hat mount - scaffold often has low clearance, and the selfie stick gives you more control over camera position
  • Hold the camera in the hand closest to the building - this way your body faces outward and doesn’t block the facade from the camera’s view

 

Common mistakes and how to avoid them

These are the most frequent issues that lead to poor scan quality or a Cancelled scan. If your scan looks wrong after processing, check this list first.

Mistake

What goes wrong

How to avoid it

Rushing through rooms

Gaps in coverage, missed areas, low image quality

Walk like you’re carrying a cup of coffee. Pause in small rooms.

Poor or uneven lighting

Grainy images, blurred images, processing failures

Turn on all static lighting. Use a diffuse light attachment in dark areas. Never use a beam torch.

Dirty camera lenses

Blurry or smeared images across the entire scan

Wipe both lenses with the microfibre cloth before every scan.

Holding camera in hand at body height

Body blocks parts the 360° view, processing problems, cancelled scans

Hard hat mount or selfie stick held above head height.

Missing rooms (toilets, plant rooms, storage)

Gaps in site record, coverage complaints from office team

If it’s on the floor plan, scan it. Plan your route before you start.

Inaccurate start or end location

Scan appears misaligned on the floor plan, processing delays

Zoom in and place the pin precisely on a recognisable fixed point.

Using a lift mid-scan without stopping

Processing delays

Stop the recording before entering any lift. Start a new scan when you exit.

Not using Oculo mobile app

Unsupported recording modes, processing delays, cancelled scans

Always use Oculo mobile app

 

What a good scan looks like

When your scan is published, you and your team should be able to:

  • Navigate every floor and room of the scanned area from the floor plan
  • See clear, sharp 360° images in every scene - no blurring, dark areas or grainy images
  • Identify exactly where each scene is on the floor plan - the path should match your walking route
  • Compare this scan against previous scans of the same area to see clear progress

 

Not quite right?

If your published scan has blurry images, stitching errors, or appears misaligned on the floor plan, check the Common mistakes section above and note what might have caused it.
