Bosch CLEAR BUBBLE FLEXIDOME DUAL - NDA-7042-CBL

Bosch NDA-7042-CBL Clear Bubble for FlexiDome Dual Cameras

Overview

The Bosch NDA-7042-CBL is the OEM clear polycarbonate replacement bubble for the FlexiDome Dual camera family. When an installed dome cover is scratched, fogged, or damaged, swapping it with a genuine NDA-7042-CBL restores optical clarity without pulling the camera from service — no re-aiming, no re-focusing, no downtime beyond the cover swap itself.

At 74.5 mm x 46.2 mm and 50 g, the bubble is dimensioned specifically for the FlexiDome Dual housing. Using a non-OEM substitute risks misfit tolerances that break the weather seal and introduce optical distortion at the dome edge — neither outcome is acceptable on a camera that feeds evidential footage.

Key Features

• IK10 impact resistance: IK10 is the highest standardized impact rating — the bubble withstands a 20-joule impact (roughly a 5 kg mass dropped from 400 mm). In retail, education, or public-space deployments where vandalism is a known risk, IK10 means a strike that would crack a lower-rated dome does not take the camera offline.
• Polycarbonate transparent construction: Polycarbonate transmits light with minimal absorption, preserving the imaging chain from lens to scene. A clear (non-tinted) bubble avoids any IR-cut effect on cameras that rely on 850 nm or 940 nm illuminators — night performance stays intact.
• Precision OEM fit: At 74.5 mm x 46.2 mm, this bubble matches the FlexiDome Dual housing tolerances exactly. A correct fit maintains the housing's environmental seal; an ill-fitting aftermarket part can void the camera's IP rating by breaking the gasket interface.
• Lightweight at 50 g: The low mass means no mechanical stress on the housing retention clips during installation or from long-term vibration — relevant on ceilings with HVAC-driven movement.

Compatibility

The NDA-7042-CBL (also searched as NDA 7042 CBL) is designed for the Bosch FlexiDome Dual camera series. Confirm your camera model against the FlexiDome Dual family before ordering — other FlexiDome variants (single-sensor, outdoor, or IP starlight models) use different bubble geometries and are not interchangeable. Consult the Bosch Security camera line or the specific camera's accessory list to verify fit before purchase.

If you are sourcing a replacement as part of a broader dome camera refresh, see the full range of dome cameras and camera accessories for complementary parts. For installations requiring IK10-rated complete camera systems, an outdoor IP camera with an integrated vandal-rated housing may be a more efficient path than field-replacing bubbles repeatedly.

Frequently Asked Questions

Q: Which camera models is the NDA-7042-CBL compatible with?

A: The NDA-7042-CBL is the OEM clear bubble for the Bosch FlexiDome Dual camera family. Verify your specific camera model against the FlexiDome Dual accessory list — other FlexiDome variants use different dome geometries.

Q: What impact rating does the NDA-7042-CBL dome bubble carry?

A: It is rated IK10, the highest level in the IEC 62262 impact protection scale, corresponding to a 20-joule impact resistance.

Q: Is this a tinted or clear bubble?

A: Clear (transparent polycarbonate). It does not filter IR wavelengths, so it is compatible with cameras using 850 nm or 940 nm IR illuminators without degrading night-mode performance.

Q: What are the dimensions and weight of the NDA-7042-CBL?

A: 74.5 mm x 46.2 mm, 50 g.

Q: Can I use a third-party bubble instead of the NDA-7042-CBL?

A: Non-OEM bubbles may not match the housing tolerances, which can compromise the environmental seal and introduce optical distortion. The OEM part ensures dimensional and optical compliance with the FlexiDome Dual housing.

Ted Perry

The NDA-7042-CBL is a straightforward field-replacement part, but its IK10 polycarbonate construction is worth noting: at 74.5 mm x 46.2 mm and 50 g, this bubble is dimensioned and rated specifically for the FlexiDome Dual housing — not a universal fit.

Technical Highlights:

• IK10 impact rating: 20-joule impact resistance at 50 g — meaningful in retail corridors or education environments where dome strikes happen more than operators plan for.
• Clear polycarbonate material: No IR attenuation; preserves the full imaging chain for cameras relying on 850 nm or 940 nm illumination in low-light operation.
• Precision OEM geometry (74.5 × 46.2 mm): Maintains the housing's environmental seal interface — a non-OEM part with even slight dimensional variance breaks the gasket fit and can degrade any IP rating the camera carries.

Deployment Considerations:

• Confirm the FlexiDome Dual model number before ordering — FlexiDome single-sensor and outdoor variants use different bubble profiles and the NDA-7042-CBL will not seat correctly.
• No IP rating is published for this bubble in isolation; the housing's rated ingress protection depends on the full assembly including the camera body gasket — replacing only the bubble restores optical performance, but verify the gasket condition simultaneously.

Best suited for facilities maintenance programs on existing FlexiDome Dual deployments — retail chains, university campuses, or transit operators running scheduled dome inspections where a scratched or hazed bubble is the only failure mode and the camera body is otherwise sound.
