Camera specification
360 camera specification for construction: the published figures, side by side
The strictest published 360 camera specification for construction is in BCA's Guidebook for Virtual TOP/CSC (360 Capture). It sets at least 6K resolution, dual one-inch CMOS sensors, low-light capability, 60 to 90 minutes of continuous recording and six-axis stabilisation. Hong Kong public works contracts set 1080p at 30 fps, 9 hours of battery and 400 g or less for worn cameras. Japan's MLIT sets reference values for live video of 640 by 480 pixels at 15 fps. SpatialSense works with the Insta360 X4, X5 and X6 and the DJI Osmo 360, which all record 8K.

Three published specifications, three purposes
Each published figure answers a different use. Singapore's is for a stored capture that a regulator inspects in place of a visit, so it asks for the most detail. Hong Kong's is for a camera worn through a working shift, so it asks for battery life, storage and low weight. Japan's is for live video over a web conference, so it asks only for what a mobile connection can carry.
A specification for a tender should start from the use. If the record will be inspected or measured from, write the Singapore figures. If the camera is worn all day, add the Hong Kong ones. If supervisors watch live, add a minimum stream.

From the issuing bodies' documents, checked in November 2026.
| Item | Singapore, BCA guidebook | Hong Kong, public works contracts | Japan, MLIT guidelines |
|---|---|---|---|
| Purpose | Stored 360 capture for TOP/CSC inspection | Camera worn on site inspections | Live video for remote attendance and inspection |
| Camera type | 360 camera | Body-worn video camera. A helmet-integrated camera may be proposed | Video camera, such as a wearable or 360-degree camera |
| Resolution | At least 6K | 1080p or higher | 640 by 480 or more. 1920 by 1080 for government building works |
| Frame rate | Not stated | 30 fps or higher | 15 fps or more. 30 fps for government building works |
| Sensors | Dual one-inch CMOS, suitable for low light | Low-light recording | Colour |
| Battery | 60 to 90 minutes of continuous video capture | 9 hours of continuous 1080p30 recording | Not stated |

Hong Kong's figures come from recent public works contract specifications. DEVB publishes no central camera specification, so the contract governs.
A 360 camera clause for a tender
Wording a client can adapt where no regulator sets the figures. Each item follows one of the published specifications above.
The camera
- A dual-lens 360 camera supporting at least 6K resolution
- Dual one-inch CMOS sensors, suitable for low-light conditions
- Six-axis stabilisation
- At least 60 minutes of continuous capture on one battery, with spare batteries for the shift
- Helmet, monopod or tripod mounting for hands-free capture
The platform
- Every capture tied to the approved floor plan, with its date and time
- Continuous capture for large areas and spot capture for small rooms
- Comments and photo evidence attached at the position they concern
- Viewer access for the client, the consultant and the authority
- A report of all comments and their closure
The record
- A walk of every accessible level at the stated interval
- A walk before any work is covered
- Footage stored securely, with an audit trail of who opens it
- Retention and deletion periods stated in the contract

Camera specification questions
What resolution does a 360 construction camera need?
At least 6K if the capture will be inspected by a regulator. That is the figure in section 4.1 of BCA's Guidebook for Virtual TOP/CSC (360 Capture). Hong Kong public works contracts set 1080p for worn cameras, and Japan's MLIT sets 640 by 480 for live video.
Why does BCA ask for one-inch sensors?
The guidebook pairs dual one-inch CMOS sensors with suitability for low-light conditions. Finished interiors, plant rooms and stair cores are often dim, and a larger sensor keeps the detail an inspector needs.
How long should the battery last?
BCA's guidebook sets 60 to 90 minutes of continuous video capture, enough for a walk of several floors. Hong Kong contracts set 9 hours of 1080p30 recording for a camera worn through a shift. Spare batteries cover a full day of 360 capture.
Is 5.7K enough for a 360 construction camera?
It falls short of BCA's 6K figure. Some contract specifications set 5.7K as their own minimum. A 6K camera meets both.
Which 360 camera should I choose for construction?
For a BCA virtual inspection, the one with the largest sensors, the Insta360 X6 or the DJI Osmo 360. Both record 8K with two 1/1.1-inch sensors, the closest to the guidebook's one-inch figure. For progress walks and Hong Kong worn-camera clauses, the Insta360 X4 or X5 records 8K, above those figures. SpatialSense works with all four.
Does the camera need stabilisation?
Yes for a walking capture. BCA's guidebook sets six-axis stabilisation with an image stabilisation algorithm, so the footage stays level and smooth at walking pace.
Can one camera serve as both the 360 camera and the body-worn camera?
Hong Kong contract specifications allow a camera that integrates with a smart safety helmet in place of a chest or shoulder camera, if it meets the rest of the clause. Kodifly's 360 helmet camera is offered on that basis.
What else should the specification cover besides the camera?
The platform and the record. BCA sets eight platform requirements, including tying every capture to the building plan, access for inspectors, comment tagging and a closure report. A camera without them produces footage, not a record.
