DEVB requirement, June 2026
Body-worn cameras for Hong Kong public works inspections
Since June 2026, the Development Bureau (DEVB) requires frontline resident site staff and contractors' frontline staff on all public works contracts to wear body-worn video cameras (BWVC) during site inspections. The Kodifly 360 helmet camera with SpatialSense meets it, and turns each inspection into a dated record on the floor plan, linked to the DWSS.
Source - LC Paper CB(1)749/2026(02) and the Secretary for Development's reply to LCQ13, 24 June 2026.
DEVB's wording is "the frontline personnel of RSS and contractors in all public works contracts to equip with BWVCs during site inspections since June 2026" (LC Paper CB(1)749/2026(02), paragraph 40). No public circular sets a camera specification, so check the clause in your own contract.
What DEVB asks, and how the Kodifly 360 helmet camera and SpatialSense meet it
DEVB gives four purposes for the cameras. Each row takes one part of the requirement and says what we provide.
| Requirement | What DEVB says | Kodifly |
|---|---|---|
| Worn during site inspections | Frontline staff carry a body-worn video camera when they inspect the site. | Live |
| Frontline resident site staff and contractors | Both the resident site staff (RSS) and the contractors' frontline staff are covered, on all public works contracts. | Live |
| Site supervision | Cameras are there to support site supervision. In SpatialSense each walk is dated, placed on the floor plan and linked to the inspection request and site diary in the DWSS. | Live |
| Safety management | Cameras support safety management. AI reads each frame, flags safety findings ranked by severity, and the engineer reviews them before anything is issued. | Live |
| Quality control | Cameras support quality control. Keep a dated record of what was inside before it was covered, and compare what is built with the BIM model. | Live |
| Works progress monitoring | Cameras support progress monitoring. Each floor is scored against the last visit, so progress is read from the record, not remembered. | Live |
| Record handling | Footage of people is personal data. SpatialSense keeps footage in the project record behind the project login, with audit trails as the DWSS requires, and the retention period follows your contract. | Live |
| Camera particulars in your contract | DEVB has published no weight, battery, storage or resolution figures. Send us the clause in your specification and we will answer it point by point. | Check your specification |
A helmet-mounted camera is worn on the body. DEVB does not define the term, so confirm with your project office that it satisfies the clause in your contract.
One walk, one record
The inspection and the evidence are the same thing
Put the helmet on and walk the works. The 360 footage is placed on the floor plan with its date and time, so it is a record of the inspection, and the reviewer finds it where the work is, not in a folder of video files.
- Hands-free, so the inspector keeps both hands for the work.
- Covers the whole scene, not only where a chest camera points.
- Links to the inspection request that approved the works, and to the site diary.
- Searchable in plain language across the whole project.
An inspection with a body-worn camera
From the helmet to the signed-off record.
Put the helmet on
The inspector starts the 360 camera at the start of the inspection.
Walk the works
One walk covers the zone, whether it is rebar before a pour or services above a ceiling.
Footage lands on the plan
Each capture is dated and placed on the floor plan, with its capture ID.
AI drafts the findings
AI marks objects and safety findings and drafts the inspection form for review.
The engineer signs off
The engineer reviews, links the record to the inspection request, and it joins the DWSS.
Why a 360 helmet camera for BWVC
What it does well, and where it stops.
Evidence on the plan
Footage is placed by date and position, so a finding stays attached to the place it came from.
Same record as your DWSS
The record is the site record DEVB already asks for. It is not a second system to reconcile.
Feeds the Co-supervision Platform
The Co-supervision Platform can take body-worn camera data as one of its inputs, next to 4D LiDAR and AI cameras.
A clear line on scope
We say what is live and what depends on your contract, so your specification and our proposal line up.
Body-worn cameras are not the same as 4S, confined-space video or Co-supervision input
Four separate Hong Kong requirements involve cameras. They have different owners, scope and records.
| Requirement | Who it applies to | What it asks | Source |
|---|---|---|---|
| Body-worn cameras (BWVC) | Frontline RSS and contractors on all public works contracts | Wear a body-worn video camera during site inspections, since June 2026 | LC Paper CB(1)749/2026(02), paragraph 40 |
| Smart Site Safety System (4S) | Public works above HK$30 million | Smart devices for high-risk activities, a network and a central platform. Its wearables track location and standstill. Body-worn inspection cameras are not part of the 4S list. | DEVB TC(W) No. 3/2023 |
| Confined-space entrance video | Any proprietor or contractor doing confined-space work | Record video at the entrance and exit for the whole work period and keep it for one year, since 30 November 2024 | Labour Department Code of Practice, paragraph 12.7 |
| Co-supervision Platform | Capital works above HK$400 million tendered on or after 1 April 2026 | Adopt the platform. It can take body-worn camera data but does not require the camera. | DEVB TC(W) No. 1/2026 |
Private building sites are not covered by the DEVB body-worn camera requirement as published. A contract or a client may still ask for cameras.

Body-worn camera questions
Are body-worn cameras required on Hong Kong construction sites?
On public works, yes. Since June 2026 DEVB requires frontline resident site staff and contractors' frontline staff on all public works contracts to wear body-worn video cameras (BWVC) during site inspections (LC Paper CB(1)749/2026(02), paragraph 40). The published papers do not set the same duty for private building sites.
Who has to wear the body-worn camera?
The frontline personnel of the resident site staff and of the contractors. The papers do not require every worker to wear one for a whole shift. The duty is for inspections.
Since when does the body-worn camera requirement apply?
DEVB says it has applied since June 2026. The Secretary for Development announced it in a written reply to the Legislative Council on 24 June 2026.
Is a body-worn camera part of the Smart Site Safety System (4S)?
No. TC(W) No. 3/2023 lists smart devices such as helmets and wristbands that track location and standstill, and AI cameras. A body-worn inspection camera is a separate DEVB requirement.
Is there an official specification for the camera?
Not in the public papers. They give no weight, battery, storage, resolution or retention figures. Use the specification in your own contract, and be careful with supplier pages that quote "typical" figures.
Can a 360 helmet camera count as a body-worn camera?
DEVB does not define the term. A 360 helmet camera is worn on the body and records the inspection, and it is what Kodifly uses for its own site walks. Confirm with your project office that it meets the clause in your contract.
How is the footage kept and who can see it?
In SpatialSense the footage is part of the project record behind the project login, linked to the inspection and the DWSS. The retention period follows your contract. Footage of identifiable people is personal data under the Personal Data (Privacy) Ordinance, so tell people they are being recorded and limit access.
What about video in confined spaces?
That is a separate rule. The Labour Department's Code of Practice, in effect since 30 November 2024, asks the proprietor or contractor to record video at the entrance and exit of a confined space for the whole work period and keep it for one year (paragraph 12.7).
