01Document the physical limit
Confirm the measured access restriction and the intended target.
Check access where height matters
Height-restricted access needs reliable physical limits and clear procedures. A camera workflow may flag a candidate visual condition, but actual height or safe clearance requires a calibrated method or direct measurement appropriate to the access point.
Confirm detector support, camera suitability and the proposed event workflow before deployment.
Validate height-access requirements

How It Works
Treat the camera view as a cue for clearance review Help operators identify access situations needing a physical height-clearance check.
01
02Validate the visual method
Test perspective, reference geometry and supported model behavior.
03Review a candidate exception
Check the image and obtain a reliable physical measurement.
04Follow access procedures
Authorized staff decide whether and how passage is permitted.

| Dimension |  Restricted-height access detection |  Restricted Zone Monitoring |
|---|---|---|
| Observation |  A visible object or person relative to a height-reference area. | Supported people or objects within a defined image area. |
| Event criteria | A separately validated visual criterion indicates a possible height-access exception. | A validated presence condition occurs inside the selected zone. |
| Monitoring setup | Define the physical restriction, target type and measurement method before specifying the rule. | Confirm zone geometry, relevant classes and operating context. |
| What it cannot establish | Uncalibrated image size does not establish physical height, clearance or safe passage. | Presence does not establish identity, access permission or malicious intent. |
| Practical outcome | Help operators identify access situations needing a physical height-clearance check. | Help operators check activity where access requires extra scrutiny. |

What Can You Do With Restricted-height access detection?
01 / 04 · RESTRICTED-HEIGHT ACCESS DETECTION
Logistics
Raised loads may need clearance verification.
Example event: A load appears near the validated visual reference.
Operator response: Measure or verify clearance before allowing movement.
Practical value: Focus attention on a potential access mismatch.

Commercial property
Different service vehicles use the same approach.
Example event: A candidate visual height exception is observed.
Operator response: Apply the property’s measured-clearance procedure.
Practical value: Support a structured entry check.

Deployment review
Use a surveyed stable view with an appropriate reference plane.
Visibility: Perspective and object distance strongly affect apparent height.
Configuration: Confirm that a supported calibrated method exists; do not infer 3D measurement from pixels.
Privacy: Avoid retaining unrelated personal imagery at access points.
Human review: A competent person verifies actual dimensions and safe clearance.

Frequently asked questions
Restricted-height access detection, Explained.
Review a visible person or object against a defined height-restricted access condition.
Can a normal image measure exact height?
Not reliably without a validated calibration and measurement method.
Does this cover working at height?
This workflow concerns height-restricted access; fall protection and work-at-height compliance are separate.
Can it approve vehicle passage automatically?
No automatic clearance approval is established.
What if the camera angle changes?
Recheck calibration and the visual reference before relying on observations.
