Physical Camera Installation Guide

SiteTrax camera scanning an intermodal container

For hardware installers: use this guide to mount, connect, aim, and test fixed Gate and Bring Your Own Camera (BYOC) cameras. SiteTrax.io and the customer's designated integration team handle software integration and OCR acceptance. Agree who adjusts the camera settings before the site visit.

Before permanent mounting: send representative recorded footage to SiteTrax.io for review. A clear view of a vehicle does not necessarily make its identifiers readable.

Quick reference: fixed Gate cameras

Start with these published SiteTrax.io recommendations, then validate the actual lane and markings. Measure mounting height from the road surface to the centre of the lens.

Item Starting recommendation
Rear container and chassis IDs About 3 ft (1 m) above the road. Keep both marking locations visible.
Container ID only 4–6 ft (approximately 1.2–1.8 m) above the road. Metric values are converted from the published feet range.
Camera coverage At least one camera per lane; two per lane is the published best practice. Assign each view to its intended lane, direction, and markings.
Vehicle speed 10 mph (16 km/h) or less through the capture zone.
Recorded video 1920 × 1080 at 30 fps; MP4; clips no longer than 1 minute.
Lens 6 mm or longer is the published recommendation. Select the actual focal length for the camera sensor, distance, and required view.

Sources: Gate requirements and Input Video specification. These heights apply to the stated fixed rear views, not every OCR installation. Other views, distances, angles, minimum character size in pixels, and acceptance rates are project-specific.

1. Confirm the installation brief

Before buying equipment or visiting the site, obtain a short installation brief agreed with SiteTrax.io and the customer. It must identify:

Resolve missing details before permanent installation. The quick-reference recommendations do not replace the site layout or equipment specifications. BYOC storage and software tasks belong to the designated integration team unless separately assigned.

Installation workflow: agree plan, trial position, review footage, secure installation, test day and night, record handover.

2. Trial the position and framing

  1. Use a representative vehicle at the capture zone. Trial the applicable height from the table before drilling permanent fixings.
  2. Aim as squarely as practical at the required markings. Keep text level; avoid steep downward or sideways views.
  3. Work with the camera-configuration owner to adjust optical zoom and focus so the smallest required text is readable in the saved recording at full resolution. Digital zoom cannot restore missing detail.
  4. Check the nearest and farthest vehicle positions and normal lane wandering. Include the complete identifier without clipping.
  5. Check queues, adjacent traffic, barriers, and vehicle structures for obstruction. If both container and chassis IDs cannot be captured clearly, change the position or add a view.
  6. Record moving samples and review them with SiteTrax.io before securing the final position.

Measure and record lens height, camera-to-target distance, and lane offset. Use dedicated lane/direction views as the baseline. A shared or bidirectional view requires validation with SiteTrax.io; see Gate Operations.

Illustrative coverage only; not a scale drawing or prescribed mounting geometry.

3. Secure the camera and cabling

4. Check moving images in daylight and darkness

Capture samples at the agreed maximum speed and vehicle positions. The installer adjusts physical placement and lighting; the camera-configuration owner changes image settings. Review the saved clips together:

The Gate lighting guidance provides a starting arrangement. Lamp output is not a measurement of light reaching the marking; acceptance depends on the recorded result.

5. Complete the hardware handover

Installer checklist: tick each item when checked and documented.

Send the record and clips through the agreed project channel. SiteTrax.io reviews the capture evidence and identifies any physical adjustments needed. Record hardware handover separately from final OCR acceptance.

Integration acceptance — SiteTrax.io and customer integration team

These checks belong to the designated integration team, not the hardware-only installer:
