Pelco IMD1-SPLD1 Clear Dome for Sarix Multi Surface Cameras
The Pelco IMD1-SPLD1 is a replacement clear dome engineered for Sarix Multi Pro surface-mounted outdoor camera systems. This is not a generic accessory — it's an optical component that directly affects imaging quality in both day and night modes. The dome uses optical-grade material designed to transmit light across both the visible spectrum and infrared wavelengths without significant loss, meaning your camera's sensor and built-in IR illuminator perform at their rated capability rather than being throttled by poor optics.
Key Features
- Clear optical design with maximum IR transmission: Unlike tinted or reflective domes, this clear variant preserves full sensor sensitivity across visible and near-infrared (850nm) bands — critical when you're relying on IR illumination at night. A scratched or yellowed dome scatters IR light before it reflects back to the sensor, degrading night performance silently.
- IK10 vandal impact rating: Rated to withstand 20 joules of direct mechanical impact without cracking. In high-security outdoor environments (parking lots, perimeter fences, loading docks), this matters — a broken dome is a security gap and a service call.
- Supports 1/2.8" CMOS sensor with day/night imaging: Works with Sarix Multi models that deliver 0.018 lux low-light performance using IR illumination. The dome doesn't diminish that capability; it passes the IR light through cleanly so your cameras can operate in near-total darkness without compromising detail.
- WDR and fixed lens compatibility: Maintains compatibility with wide dynamic range (WDR) processing and fixed-focal-length lens designs used in the Sarix Multi line. No optical artifacts or interference with the camera's electronic image enhancement.
- ONVIF and HTTPS encryption support: The dome itself is passive, but the camera behind it supports standardized ONVIF integration and encrypted communication — meaning your dome replacement doesn't break any existing network configuration or VMS ties.
- NDAA Section 889 compliance: If you're deploying to U.S. federal agencies, states, or contractors with supply-chain restrictions, this accessory carries the necessary certifications. No surprises during procurement audits.
Why Dome Condition Matters
Many integrators treat domes as disposable. In reality, even small optical degradation — micro-scratches, haze, internal dust — has measurable impact on night vision. IR light bounces off surface imperfections before reaching the camera sensor, and visible-light contrast suffers in low-illumination scenes. Proactive dome replacement (before visible image quality drops) prevents support calls and keeps night-time forensic value intact. For deployments where nighttime video quality is contractual (casinos, critical infrastructure, government sites), this is a scheduled maintenance item, not a failure-driven one.
Integration & Compatibility
This dome is designed exclusively for Pelco Sarix Multi outdoor cameras in surface-mount configuration. Before ordering, confirm your specific Sarix Multi model in your system documentation — not all Sarix variants use the same dome assembly. If you need a domed camera with IR that conceals the lens direction, Pelco also offers the IMD1-SPLD0 smoked variant. For broader outdoor camera dome selection, consult your system integrator or camera inventory.
Installation Guidance
Handle only with clean, lint-free gloves or approved microfiber cloths. Even fingerprints degrade optical transmission. When installing, ensure the dome seats fully in its mounting ring to prevent water ingress. Check the camera's mounting surface for cracks or corrosion before dome installation — a compromised housing will eventually leak water behind the new dome, defeating the purpose. Replace domes every 2–3 years in high-dust or high-salt-spray environments (coastal facilities, agricultural sites), or sooner if surface inspection reveals significant scratching.
Frequently Asked Questions
Q: Is the Pelco IMD1-SPLD1 compatible with all Sarix Multi models?
A: No. This dome is designed for Sarix Multi Pro surface-mounted outdoor cameras. Confirm your model in your system inventory or contact your integrator before ordering. Other Sarix variants (compact, pendant, recessed) use different dome assemblies.
Q: Does the IMD1-SPLD1 affect night vision performance?
A: A clean dome enhances it. A scratched or degraded dome reduces IR transmission before visible image degradation becomes obvious. The 0.018 lux low-light rating assumes a clear, high-transmission optical path.
Q: What is the IK10 rating?
A: IK10 means the dome can withstand a 20-joule direct impact without cracking — equivalent to a 5 kg steel ball dropped from 40 cm. Standard for high-security outdoor environments.
Q: Is the IMD1-SPLD1 NDAA-compliant?
A: Yes. It carries NDAA Section 889 compliance, required for U.S. federal and state government deployments.
Q: How often should I replace the dome?
A: In normal outdoor environments, every 2–3 years. In high-dust, coastal, or corrosive environments, inspect annually and replace if surface scratching is visible under raking light. Proactive replacement prevents silent night-vision degradation.
Q: Can I use the smoked variant (IMD1-SPLD0) instead?
A: Yes, if concealing the lens direction is a requirement. The smoked dome reduces light transmission slightly but maintains IR capability and serves the same mounting interface.

The Pelco IMD1-SPLD1 is fundamentally a light-transmission component, not a cosmetic cover. Its optical clarity directly determines whether your camera's sensor and IR illuminator can deliver their rated performance in darkness. The 0.018 lux specification on the Sarix Multi means nothing if the dome is hazy — you've paid for night-vision capability you can't access. Too many integrators discover this after a season of degraded recordings.
Technical Highlights:
- IK10 vandal rating (20 joules): Protects against deliberate impact in high-security zones. One broken dome in a perimeter fence is a $300 service call plus downtime. The rating is insurance.
- 0.018 lux IR low-light performance with clear optics: The camera delivers this only if light travels cleanly through the dome. Scratches scatter IR before it reaches the sensor — silent failure mode. Replace proactively, not reactively.
- ONVIF + NDAA compliance: Means the dome doesn't constrain your VMS choice or government procurement process. It's a plug-compatible commodity part that won't derail your architecture.
Deployment Considerations:
- Surface-mount only: confirm this matches your Sarix Multi installation. Pendant and recessed variants use different domes.
- Optical inspection is not intuitive: micro-scratches and internal haze are invisible in daylight but degrade IR significantly. Schedule dome replacement every 2–3 years in standard outdoor environments, or immediately if you see surface scratching under raking light.
- Coastal and high-dust sites: salt spray and airborne particles etch domes faster. Plan 12–18 month replacement cycles if you're near salt water or agricultural dust.
Position the IMD1-SPLD1 as preventive maintenance for government and critical infrastructure deployments where nighttime video quality is contractual. For parking lots, perimeter security, and loading docks where forensic night vision is non-negotiable, this is a 2–3 year scheduled replacement, not a failure item.
