Pelco ONXWQG NX Series Quartz Glass Front Window
The Pelco ONXWQG is a replacement front window designed for Pelco NX Series outdoor camera housings. It is engineered from quartz glass rather than standard borosilicate glass, which matters significantly in harsh industrial environments where chemical exposure, abrasive cleaning agents, or corrosive vapors degrade optical surfaces over time.
Key Features
- Quartz glass construction: Resists pitting, etching, and optical degradation from chemical contact, prolonging window service life versus standard glass in refineries, chemical processing plants, and manufacturing facilities where exposure to solvents or caustic cleaners is routine.
- Compatible with Pelco NX Series housings: Direct fit ensures proper sealing and optical alignment when replacing a damaged or degraded window — no adaptation or custom mounting required.
- Chemical resistance: Tolerates harsh industrial contaminants, abrasive cleaning agents, and environmental stressors that would cloud or pit standard glass, reducing replacement frequency and associated downtime.
- Seamless integration: Maintains the optical performance and weatherproofing of the original housing assembly when installed correctly.
- 5-year warranty: Covers manufacturing defects and material failure, providing predictable replacement cost over a typical surveillance installation cycle.
- NDAA Section 889 compliant: Meets federal acquisition requirements for government, state, and local installations where supply-chain compliance is mandatory.
When to Use This Window
The ONXWQG addresses a specific failure mode: optical degradation in chemically aggressive environments. Standard glass windows supplied with Pelco NX Series housings perform adequately in outdoor environments with rain, dust, and temperature extremes. However, they degrade rapidly when exposed to:
- Chemical vapor or spray from processing operations
- Abrasive cleaning methods (pressure washing with solvents)
- Caustic fumes or acidic atmospheres
- Industrial contaminants in refineries, petrochemical plants, or manufacturing facilities
For standard outdoor surveillance without chemical exposure—parking lots, perimeter fencing, building exteriors in non-industrial zones—the factory-supplied window is typically sufficient and more cost-effective.
Integration with NX Series Housings
This window is a direct replacement part for existing Pelco NX Series camera housings. Ensure your housing is confirmed as an NX Series model before ordering. Installation involves unbolting the existing window assembly, cleaning the seal surfaces, and installing the ONXWQG with the same mounting hardware. Refer to your specific housing documentation for detailed removal and installation steps. Proper seating of the window gasket is critical to maintain the IP rating of the housing.
Deployment Considerations
Chemical-resistant windows are a maintenance accessory, not a performance upgrade to the camera itself. They extend the service life of the optical path in aggressive environments, reducing the frequency of window replacement. Plan for periodic window inspection—pitting or etching that reduces image clarity is the replacement trigger, not a fixed schedule. Stock a spare ONXWQG if you have multiple NX Series cameras in chemically aggressive locations to minimize downtime during window swaps.
Frequently Asked Questions
Q: Is the ONXWQG compatible with all Pelco NX Series camera models?
A: The ONXWQG is designed as a replacement window for Pelco NX Series outdoor camera housings. Verify your specific housing model is part of the NX Series product line before ordering. Refer to your housing documentation or contact Pelco technical support if you are uncertain about your model.
Q: How often should I replace the window in a chemical environment?
A: Replacement interval depends on the severity and type of chemical exposure. Inspect the window regularly for pitting, etching, or cloudiness that impairs image clarity. Some industrial customers replace windows annually; others every 2–3 years. Quartz glass extends the interval compared to standard glass, but it is not immune to all chemical attack.
Q: Does the ONXWQG improve camera image quality?
A: No. This window preserves optical clarity in harsh environments by resisting degradation. Image quality is determined by the camera sensor, lens, and firmware. The ONXWQG prevents the loss of clarity caused by surface damage, not enhancement of the original optical path.
Q: What is the warranty coverage on the ONXWQG?
A: The ONXWQG includes a 5-year warranty covering manufacturing defects and material failure. This warranty does not cover damage from improper installation, impact, or chemical attack beyond the design limits of quartz glass.
Q: Can I use the ONXWQG in submersion or high-pressure wash environments?
A: The window itself is quartz glass, which is resistant to chemical and mechanical stress. However, the waterproof integrity depends on proper sealing in the NX Series housing. Do not subject the assembled housing to direct high-pressure spray unless the housing documentation explicitly approves that use. Improper sealing can allow water intrusion regardless of window material.
Q: Is the ONXWQG NDAA Section 889 compliant?
A: Yes. The ONXWQG meets NDAA Section 889 compliance requirements for federal, state, and local government installations and regulated procurement environments.

I recommend the ONXWQG only if you are replacing a window that has already failed due to chemical exposure. The quartz glass construction of the ONXWQG delivers measurably superior chemical resistance and optical longevity compared to standard borosilicate glass in aggressive industrial environments. If you are specifying a new Pelco NX Series installation and anticipate chemical exposure, budget for the ONXWQG at commissioning rather than as an afterthought—it will reduce downtime and replacement labor over the life of the system.
Technical Highlights:
- Quartz glass substrate: Resists pitting and etching from solvents, caustics, and abrasive cleaners that pit standard glass within months in refineries or chemical plants. The difference in replacement interval is measurable: annual for standard glass versus 2–3 years for quartz in equivalent exposure.
- Direct fit for NX Series housings: No custom machining or adapter plates required—bolts directly into existing housing mounting points, maintaining the original IP rating seal and optical axis alignment.
- 5-year manufacturing warranty: Covers defects in glass or sealing surfaces, reducing your exposure to glass-related failures during the typical surveillance contract period.
- NDAA Section 889 compliance: Eliminates procurement delays in federal or regulated-industry deployments where supply-chain documentation is non-negotiable.
Deployment Considerations:
- Maintenance trigger: This is a replacement part, not a preventative upgrade. Order when optical degradation becomes visible in live video or recorded feeds, or when you see surface etching during visual inspection. Do not stock a spare unless you have multiple NX Series cameras in the same chemical environment.
- Watch for incomplete sealing: Installation skill matters. A poorly seated gasket will allow moisture intrusion regardless of window material. Ensure the technician cleans the seal surfaces and applies appropriate gasket compound per the NX Series housing manual.
- Chemical specificity: Quartz glass resists most industrial chemicals, but not all. If your environment includes hydrofluoric acid or other exotic corrosives, contact Pelco technical support to confirm suitability before ordering.
Deploy the ONXWQG in refineries, petrochemical plants, chemical processing facilities, and manufacturing environments where window replacement every 1–2 years is a known operational cost. For outdoor surveillance in non-industrial zones—parking, perimeter, general commercial—stick with the factory glass window and avoid the cost.
