Mechanical¶

Pressure class: 600 bar
Materials: 316L housing + sapphire optical port
Mounting / envelope / drawings: coming soon
Sealing concept & test procedure: coming soon

Optics¶

FOV: 100°
Focus: Fixed
Port-induced distortion: minor (introduced primarily by the optical port)
Preliminary placeholder: ~1–3% radial distortion at the image edge
Calibration profile: coming soon

Imaging (high level)¶

Effective resolution: 2064 × 1552 (~3.2 MP)
Max sensor readout: up to 125 fps (mode-dependent; configuration-dependent)
Bit depth / HDR / low-light / spectral response: coming soon
Image examples & characterization plots: coming soon

Electrical & interface¶

Single coax link: video + control on one coax (no separate control wiring)
Pinout / power input / polarity / protections: coming soon
Power consumption & heat dissipation: very low (negligible housing heat rise in typical use)
Verified numbers: coming soon

Thermal¶

Passive heat path via metal housing → seawater
No active cooling required under typical operating conditions
Thermal limits & validation: coming soon

Environmental & robustness¶

Designed for long-term subsea operation with emphasis on: - Corrosion-resistant construction (316L + sapphire) - Robust single-cable architecture (fewer penetrations, fewer connectors) - Shock/vibration suitability for ROV operations: coming soon (test plan & results)

Reliability & operation¶

Single coax simplifies installation and reduces failure points
Link health monitoring / fault behavior / recovery behavior: coming soon
Recommended installation practices:
Strain relief at camera and VPU ends
Maintain appropriate bend radius
Avoid abrasion points and sharp edges

Safety¶

Electrical safety features (ESD/overvoltage/overcurrent, brown-out behavior): coming soon
Fail-safe behavior on link loss / power interruption: coming soon
Handling & pressure-safety notes: coming soon

Compliance¶

Documentation and compliance roadmap: coming soon
(Planned focus areas: EMC, product safety, RoHS/REACH where applicable.)
