Body-Worn Camera System (BWVC)

Frontline video evidence · 4G live streaming · Dock auto-offload & charging · Works-contract spec ready

Dahua MPT230 4G body cameras paired with the EEC400-D data collection station give site frontline and resident site staff one-press recording with GPS watermarking, night vision and stabilisation, plus automatic encrypted archiving kept on site; an optional DSS platform adds 4G live view, positioning and group talk — matching government works-contract BWVC specifications and confined-space recording requirements.

Overview

Body-Worn Camera System (BWVC)

Challenges

  • Site inspections, works acceptance and incident investigations often come down to one person's word against another's — who did what, when, and what the site actually looked like.
  • In Hong Kong, body-worn cameras are no longer just for the Police: frontline officers of the Marine Department, Correctional Services and Department of Health already carry them, public works contracts have begun specifying body-worn cameras for resident site staff (RSS), and the revised Code of Practice for Safety and Health of Confined Space Work, effective end of November 2024, requires video recording at confined-space entrances with technological devices during works.
  • Frontline video records are fast becoming standard site equipment.
  • New Forward pairs the Dahua DH-MPT230 4G body camera with the DH-EEC400-D data collection station as a complete solution.

Solution Design

- The MPT230 records at the press of one button, with a 146° ultra-wide lens, electronic image stabilisation (EIS) and up to 2K resolution, while the OSD automatically watermarks time, user, device and GPS coordinates onto the footage.

- 120-second pre-record and 600-second post-record ensure critical moments are never missed.

- With 0.0001 lux ultra-low-light capability, 10 m infrared and an LED light, it keeps filming in tunnels, basements and night works.

- The body weighs just 183 g, is IP68 rated, passed four 2-metre drop tests, operates from −20°C to +55°C, and mounts hands-free with Klick-Fast chest or shoulder fittings — built for site conditions.

- At the end of a shift, dropping the camera into the EEC400-D station automatically offloads, archives and charges it and updates firmware — 8 cameras simultaneously at up to 64 MB/s.

Core Benefits

- Four SATA bays (up to 16 TB per disk) support RAID redundancy, footage is AES-256 encrypted with station account controls, and recordings are retained on site for 7 days or longer as the contract requires, searchable by time, user and type via the HDMI screen or web interface.

- No cloud, no monthly platform fees, and the data stays on site; bilingual "Video & Audio Recording In Progress" labels, a designated data officer and access workflows align with the Personal Data (Privacy) Ordinance and the Privacy Commissioner's guidance on notices, retention, encryption and access.

- Where central monitoring is needed, an optional DSS management platform (Tier 2) connects cameras directly over 4G or Wi-Fi: the control centre watches frontline video live, tracks GPS locations and plays back trajectories, with PTT group talk and one-press SOS with automatic location — ideal for ground-level supervision of confined-space and high-risk works and for multi-site management (one 4G data SIM per camera, client-provided, no fixed IP needed).

- The solution addresses common government works-contract BWVC clauses — weight ≤400 g (183 g here), ≥9 hours continuous recording (11.5 hours at 1080p), storage expandable to 256 GB, ≥7-day retention, encryption and access control, operator training and maintenance response within 2 working days — with a clause-by-clause compliance statement available per contract, and can be deployed alongside the Smart Site Safety System (SSSS).

Deployment & Operations

- From supply and installation to training and maintenance, New Forward handles it end to end.

Key features

One-press recording · pre/post-record

146° ultra-wide lens with EIS and up to 2K resolution; records at one press with 120 s pre-record and 600 s post-record, and the OSD watermarks time / user / device / GPS onto footage usable as acceptance and investigation evidence.

Night vision & ultra-low light

0.0001 lux ultra-low-light (B/W mode), 10 m infrared with auto/manual switching plus an LED light; automatic day/night switching keeps night works, tunnels and basements clearly visible.

Site-grade durability · full-shift battery

183 g light, IP68 rated, passed four 2 m drop tests, operates −20°C to +55°C; the 3200 mAh battery records 11.5 hours at 1080p and is hot-swappable, with roughly a 5-minute power buffer so recording continues during battery changes.

EEC400-D auto archiving · encrypted on-site storage

Docking triggers automatic offload, charging and firmware updates — 8 cameras at once at up to 64 MB/s; 4× SATA bays (16 TB per disk) with RAID support, AES-256 encryption, account controls and HDMI/web search and playback by time, user and type. No cloud, no monthly fees.

4G live view · GPS / PTT / SOS (optional)

With the optional DSS platform the control centre watches frontline video in real time with GPS tracking and trajectory playback, PTT group talk and one-press SOS with auto-location; dual nano-SIM design suits ground supervision of confined-space and high-risk works.

Works-contract specs & privacy compliance

Weight, endurance, storage, retention, encryption, training and maintenance-response clauses are addressed item by item, with a compliance statement available; bilingual recording notices and access workflows follow the PDPO and Privacy Commissioner guidance.

FAQ

Do we need a subscription or cloud service?
No. The base Tier 1 setup stores and manages footage locally on the EEC400-D at the site — no platform licence, no cloud fees, no SIM cards — which also keeps privacy control simple. Add the optional DSS platform (Tier 2) only when you need live streaming; each camera then needs a 4G data SIM (client-provided), with no fixed IP required.
Our works contract specifies body-worn camera requirements — can you comply?
Yes. The solution is designed around common works-contract clauses: 183 g body (typical limit ≤400 g), 11.5 hours of continuous 1080p recording (typical requirement ≥9 hours), storage expandable to 256 GB, on-site retention of 7 days or more, AES-256 encryption, bilingual recording labels, operator training and maintenance response within 2 working days. A clause-by-clause compliance statement can be submitted against your contract's specification annex.
Does this help with the revised confined-space Code of Practice recording requirement?
The revised Code of Practice for Safety and Health of Confined Space Work, effective 30 November 2024, requires employers/contractors to video-record at confined-space entrances with technological devices during works. Body-worn cameras serve as flexible recording devices for this, and the optional DSS platform adds live 4G feeds for surface monitoring. Note that, like mainstream body cameras generally, the IP68-rated MPT230 carries no ATEX explosive-atmosphere certification, so zones with flammable-gas risk (e.g. some manholes and drains) need a separate risk assessment — confirm compliance arrangements with your safety officer or consultant.
How is staff privacy handled under the PDPO?
The solution builds in the key controls: bilingual "Video & Audio Recording In Progress" labels on each unit, AES-256 encryption, station account permissions and access control, configurable retention with regular deletion, and a recommended designated data officer with access workflows. Induction training covers notices, retention and access arrangements in line with Privacy Commissioner guidance and your company's privacy policy.
Will the battery last a full shift? Can it film at night or in basements?
The 3200 mAh battery records up to 11.5 hours at 1080p (about 12 hours at 720p) — generally a full shift; the battery is removable, and a built-in backup cell provides roughly a 5-minute power buffer so recording is not interrupted during battery changes. For low light, 0.0001 lux (B/W) with 10 m infrared and an LED fill light switches day/night automatically, covering night works, tunnels and basements.
