Manufacturing feasibility assessment
5. Verdict
Add conspicuous recording indicators, physical camera/mic controls, encrypted storage, consent workflows, and regional privacy compliance; BOM can fit target, then certify BLE/RF and pilot 100 units.

7. Bill of materials
| Item | 100 | 1,000 | 10,000 |
|---|---|---|---|
| 7.1 1080p camera module with lens | $13–18 | $7–10 | $4–6 |
| 7.2 BLE/MCU compute module and RF parts | $18–27 | $11–16 | $7–10 |
| 7.3 64–128 GB managed flash | $9–14 | $6–9 | $4–6 |
| 7.4 Dual MEMS microphones and audio front end | $4–7 | $3–5 | $2–3 |
| 7.5 Li-ion battery, PMIC, USB-C and protection | $6–9 | $4–6 | $3–4 |
| 7.6 Rigid-flex PCB, passives and connectors | $11–16 | $7–10 | $4–6 |
| 7.7 Molded enclosure, clip, shutter and hardwired LED | $11–16 | $7–10 | $4–6 |
| 7.8 Assembly, calibration, functional test and packaging | $10–15 | $6–9 | $4–6 |
At 10k units, production tooling amortises to about $18–35/unit: 12–24% of $149 retail or 6–12% of $299 retail. The $32–47/unit 10k BOM stays below 40% of the $149 floor, before cloud, warranty, channel margin, and returns.
8. Gates to clear
8.1 [DFM]
BLE-only bulk sync is a user-experience pothole, and an unshuttered covert-looking camera will poison trust before launch.
Path: Rev A must add USB-C media export, a mechanical shutter, and a LED wired directly to camera power; run EVT with an ODM experienced in wearable camera modules, then DVT drop, sweat, thermal, and antenna tests.
8.2 [Certification]
A global recording pendant faces radio, battery, product-safety, and consent obligations; “it has an LED” is not a compliance strategy.
Path: Use an accredited lab sequence: FCC Part 15 and ISED for US/Canada; CE RED, EMC, RoHS, WEEE and UKCA for Europe/UK; IEC 62133 and UN38.3 for the battery; Bluetooth SIG qualification. Launch by region with recording notices, GDPR controls, and jurisdiction-specific consent guidance.
8.3 [Tooling]
Below roughly 5k units, molds, fixtures, certification, and cloud support turn the $149 price point into a margin-eating hobby.
Path: Pilot with CNC/SLS housings and a contract manufacturer at 100–500 units, validate paid retention and transfer behavior, then cut production molds only after 5k+ funded demand or a $249–299 launch SKU supports the ramp.
9. Prototype sequence
- 9.1Build a 20–40 unit bench prototype using an off-the-shelf camera/BLE board, 64 GB storage, dual mics, and USB-C export.Validates capture quality, battery draw, storage consumption, and whether users will actually wear the thing.
- 9.2Implement encrypted local storage, explicit start/stop controls, hardwired LED behavior, and server deletion/retention controls.Privacy architecture must be designed before content volume and cloud habits make it expensive to unwind.
- 9.3Run a 25–50 user field trial with researchers, journalists, and accessibility users under written consent protocols.Measures transfer pain, transcription value, false object tags, social acceptability, and real recording duration.
- 9.4Build EVT hardware with the physical shutter, USB-C, production-intent antenna layout, battery protection, and breakaway wear mechanism.Closes the required product changes before RF, thermal, drop, and sweat testing expose costly enclosure rework.
- 9.5Engage a wearable ODM and accredited compliance lab for DVT, pre-scan, battery transport testing, and regional certification planning.Turns a plausible prototype into a certifiable product instead of a polished demo with paperwork ambushes.
