Hanwha SBV-136BW Waterproof Aluminum Back Box
The SBV-136BW is a purpose-built weatherproof enclosure designed to house and protect outdoor surveillance cameras in harsh environmental conditions. Constructed from aluminum with an IP66 rating, this back box bridges the gap between your camera and the mounting surface, safeguarding electrical connections and cable entries from direct water ingress, salt spray, and temperature cycling. If you're deploying outdoor IP cameras in coastal zones, industrial sites, or regions with persistent moisture, this accessory is essential to system longevity.
Key Features
- IP66 waterproof rating: Protects internal connections from rain, dust, and high-pressure water jets. This rating means direct spray and heavy downpour won't penetrate the enclosure—critical for extended equipment life in wet climates.
- Aluminum construction: Offers corrosion resistance superior to steel while keeping weight low enough for wall or pole mounting without reinforcement. The material won't rust or degrade in saltwater environments common to coastal installations.
- Knockout cable entry panels: Pre-scored openings allow you to customize entry points for power, network, and coaxial cables without drilling. This tool-free approach reduces installation labor and preserves the waterproof seal when knockouts are properly utilized.
- White finish: Blends with building exteriors and reduces heat absorption compared to dark finishes, which can extend camera electronics lifespan in direct sunlight.
- Compatible with Hanwha outdoor surveillance cameras: Integrates with the Hanwha camera lineup for standardized mounting and cable routing.
- Corrosion-resistant design: Aluminum construction resists oxidation and maintains structural integrity over years of outdoor exposure, reducing replacement cycles.
Integration & Compatibility
The SBV-136BW (often searched as SBV 136BW) is engineered specifically for outdoor surveillance camera installations where the camera body, lens, and internal circuitry must be isolated from moisture. It provides a weatherproof transition zone between your mounting bracket and the camera housing itself. Verify camera-to-back-box mechanical compatibility with the camera's datasheet before ordering; not all outdoor cameras require a separate back box—some models integrate weatherproofing internally.
Installation Considerations
Knockout panels eliminate the need for hole saws or drilling tools, accelerating field deployment. However, proper knockout utilization is critical: any unused knockouts should remain sealed, and cables routed through active knockouts must be positioned to prevent water pooling or capillary wicking. When installing in high-wind zones or on tall poles, ensure your mounting bracket and back box are rated for the combined load of the camera and enclosure. In applications requiring PoE power and network switching, run cabling with adequate slack to prevent tension on connections inside the box.
When to Choose a Different Approach
If your camera already includes integrated weatherproofing (check the camera's IP rating in its datasheet), a separate back box may be redundant. For applications requiring full submersion or extended underwater exposure, IP66 is insufficient—you would need IP67 or higher. If mounting in extremely confined spaces or on equipment with tight geometry, the back box's footprint may conflict with adjacent infrastructure.
Frequently Asked Questions
Q: Does the SBV-136BW come with mounting hardware?
A: The datasheet does not specify mounting hardware contents. Verify inclusion with the distributor or check the package contents upon receipt.
Q: Is the SBV-136BW suitable for coastal/saltwater environments?
A: Yes. The aluminum construction is corrosion-resistant and the IP66 rating protects against salt spray ingress, making it suitable for coastal installations where standard steel enclosures would degrade rapidly.
Q: Can I mount the SBV-136BW horizontally or must it be vertical?
A: The back box can be oriented to suit your mounting surface (wall, pole, bracket). Ensure knockouts used for cable entry are positioned to prevent water pooling inside the enclosure.
Q: What is the maximum combined weight the back box can support?
A: Weight capacity depends on your mounting bracket and fasteners, not the back box itself. Consult the mounting system's datasheet for load limits.
Q: Do I need the SBV-136BW if my camera is already IP66 rated?
A: Not necessarily. If the camera's housing itself is IP66-rated and all external connectors are sealed, a separate back box is redundant. Use it only if the camera datasheet specifies external mounting of connectors or power supplies that require weather protection.

The SBV-136BW back box solves a common but often overlooked problem: outdoor camera installations fail prematurely not because the camera fails, but because water finds its way into cabling, connectors, and mounting joints. The IP66 rating on this aluminum enclosure—meaning dust-tight and resistant to high-pressure water jets—is the difference between a two-year and a ten-year deployment lifespan in wet climates.
Technical Highlights:
- IP66 rating: Fully sealed against direct spray and moisture ingress, compliant with IEC 60529 standards. This is not IP65 (water jet from any direction) nor IP67 (temporary submersion); it's the sweet spot for wall-mounted outdoor cameras that won't face pooling water or full immersion.
- Aluminum chassis: Strikes a balance between durability and weight. Steel would rust faster; plastic would degrade under UV. Aluminum resists corrosion in coastal salt spray and doesn't require paint maintenance.
- Knockout design: Eliminates field drilling and the weak point that drilling creates. A single hole drilled without a grommet becomes a water entry vector; knockouts, if used and sealed properly, maintain the IP66 boundary.
Deployment Considerations:
- Knockout utilization is critical to maintaining the waterproof seal. Unused knockouts must remain in place or sealed; cut-outs must have gaskets or cable glands rated for the same IP level.
- The back box adds ~2–4 lbs (exact weight not specified in available data) to your mounting load. Verify that your wall or pole bracket can handle the combined weight of the box plus the camera without deflection.
- In direct sunlight, the white finish reflects heat better than dark alternatives, which helps keep internal components cooler and extends capacitor lifespan in power supplies mounted inside.
This accessory is non-negotiable for professional installations in coastal zones, high-humidity regions, or industrial sites with washdown protocols. It's the difference between a first-year claim and a warranty claim five years down the line.
