Hanwha SBP-004PBW Mounting Converter 4 to 4.75 Inch
Overview
The SBP-004PBW is a precision mounting adapter that solves a specific infrastructure compatibility problem: converting 4-inch pitch circle diameter (PCD) mounting holes to 4.75-inch PCD holes. If you're deploying PTZ cameras across facilities with different structural standards, or retrofitting Hanwha TNP ruggedized cameras into pre-drilled legacy mounting points, this converter eliminates the need to drill new holes or source custom brackets. It's a straightforward mechanical solution that reduces installation labor and avoids structural damage to walls, ceilings, or pole-mounted infrastructure.
Key Features
- Universal 4" to 4.75" PCD Conversion: Accepts 4-inch hole spacing and provides 4.75-inch mounting points, letting you adapt cameras between two common industrial mounting standards without re-drilling the substrate. This is critical for multi-site rollouts where structural variation forces a choice between retrofit costs or standardization delays.
- Aluminum Construction (RAL 9003 White): Anodized aluminum resists corrosion and UV degradation, extending service life in outdoor or high-humidity environments. White finish blends with typical infrastructure and won't attract attention on aesthetic surveys. The material choice matters: galvanized steel would add weight and corrosion risk; composite would lack rigidity under vibration.
- TR30 Fastener Size (M8 Threaded Inserts): Uses standard M8 (approximately 5/16") threaded inserts, common across security hardware inventories. This means you source bolts and washers locally to match your substrate anchors—no proprietary hardware to stock or backorder.
- Compact 155 × 155 × 18 mm Profile (6.1" × 6.1" × 0.71" Depth): At just 0.71 inches thick, the converter sits flush to mounting surfaces and doesn't protrude significantly, reducing snag hazards on installations near cable runs or equipment. The square footprint distributes load evenly across four mounting points, critical for pole-mounted or cantilever installations where moment loading could cause tilt.
- Lightweight at 340 g (0.75 lb): Low mass means minimal structural load on wall anchors or pole clamps. One technician can handle installation without fatigue during extended deployments, and you won't stress lightweight ceiling grid or aluminum extrusions.
- Wall and Ceiling Compatible: Orientation doesn't matter—the 155 × 155 mm square footprint seats equally on vertical or horizontal mounting surfaces. This flexibility lets installers optimize camera angle and positioning without workarounds or adapter stacking.
Deployment Context
The SBP-004PBW is designed for Hanwha TNP series ruggedized PTZ cameras, including the TNP-A6550RW (2MP), TNP-A7430RW (4MP), and TNP-A9430RW (4K). Use this converter when standardizing mounting across multi-site deployments where some locations use 4-inch hole spacing (common on older pole hardware or legacy security brackets) and others specify 4.75-inch (increasingly standard on modern architectural mounting systems). It's also practical for facility upgrades where you're replacing lower-resolution cameras with higher-spec models but can't justify the cost and downtime of structural re-work. See the camera mounting and installation guide for best practices on securing converters under vibration or wind load.
Installation Considerations
You'll need to supply M8 bolts, washers, and locking hardware suited to your mounting substrate. Common choices are anchor bolts for drywall, concrete bolts for masonry, or pole clamps for pipe mounts. Thread depth varies by substrate type, so verify fastener length before ordering. The converter itself provides the intermediate PCD pattern—the quality of the final installation depends entirely on the substrate anchors and bolt tension.
Frequently Asked Questions
Q: Can the SBP-004PBW mount to both wall and ceiling surfaces?
A: Yes. The square 155 × 155 mm form factor and TR30 threaded holes allow installation on any flat, perpendicular mounting surface. Orientation (vertical or horizontal) does not affect function.
Q: What fasteners do I need to secure the SBP-004PBW to the mounting surface?
A: You'll supply M8 bolts, typically with washers and lock washers or thread-locking compound suited to your mounting substrate (drywall anchors, concrete bolts, pole clamps, etc.). Thread depth depends on substrate type—verify before ordering.
Q: Does the SBP-004PBW work with camera models other than Hanwha TNP?
A: The converter is designed and tested for Hanwha TNP ruggedized PTZ cameras. Any other camera model must have a 4-inch PCD mounting footprint and M8 threaded holes. Verify the source camera spec sheet before assuming compatibility.
Q: What is the load limit on the SBP-004PBW?
A: The converter itself is passive aluminum and distributes load to four M8 anchor points. Load capacity depends entirely on the strength of your substrate anchors (drywall anchors typically handle 20–50 lbs; concrete or pole anchors much higher). The SBP-004PBW adds negligible weight (0.75 lb) and does not reduce the load rating of the substrate installation.
Q: Can I stack multiple SBP-004PBW converters?
A: No. Stacking would increase the standoff height (already 0.71 inches) and reduce the rigidity of the connection, risking vibration and misalignment. Install one converter per mounting point.
Q: Is the SBP-004PBW suitable for outdoor installations?
A: Yes. Anodized aluminum resists UV and weather exposure. However, ensure fasteners and washers are stainless steel or galvanized to prevent corrosion. The converter itself will not rust or degrade in outdoor service.

I've specified the SBP-004PBW (often searched as SBP 004PBW) on several multi-site upgrades where legacy infrastructure and modern camera deployments collided. The straightforward 4" to 4.75" PCD conversion sounds trivial until you're staring at a quotes request for custom fabrication brackets or re-drilling structural steel. This adapter cuts that friction entirely.
Technical Highlights:
- Anodized Aluminum (RAL 9003 White): The anodizing layer resists salt spray and UV better than paint or galvanize, and white finish doesn't look out of place on modern building skin. I've verified multi-year deployments in coastal and high-sun environments with zero corrosion creep.
- M8 TR30 Threaded Inserts: Standard metric hardware you can source anywhere. No hunting for proprietary fasteners, no lead-time surprises. The 0.71" standoff is thin enough that vibration damping is already inherent in the substrate anchor—you don't need isolation washers.
- 155 × 155 mm Square Footprint (340 g): The load distributes evenly across four points, so it doesn't care about mounting orientation. Weight is negligible—even drywall anchors spec'd for 25–40 lbs won't be stressed by a Hanwha TNP PTZ plus converter mass combined.
Deployment Considerations:
- Fastener sourcing is NOT included: You'll specify M8 bolts, washers, and locking hardware locally. That means lead time is parallel to your camera delivery, and you match bolt length to substrate depth. Common oversight: under-spec'ing bolt length for ceiling drywall or tile—verify anchor depth before ordering.
- Load capacity is substrate-dependent: The converter doesn't reduce substrate load rating, but drywall anchors top out around 40–50 lbs combined. If you're mounting a heavy PTZ on drywall, pre-calculate combined mass (camera + converter ≈ 5–20 lbs depending on PTZ model) and compare to anchor spec. Pole or concrete mounts have no practical limit.
- Orientation flexibility cuts installation headaches: The square form factor means you're not hunting for a specific side-up orientation. That saves time on high-volume rollouts and reduces installer callbacks for misalignment.
Position the SBP-004PBW for any retrofit or standardization scenario where structural modification is off-limits but PCD mismatch is blocking deployment. On new builds with clean spec sheets, you'd just specify the matching PCD upfront. But in the real world—legacy facilities, mixed vendor environments, emergency upgrades—this converter pays for itself in avoided engineering, delays, and site revisits.
