Hikvision CBMB Junction Box for Dome Camera
The Hikvision CBMB is a purpose-built junction box for protecting and routing power and signal cables in dome camera installations. Constructed from aluminum alloy with IP67 weatherproofing, it's designed to sit between a camera mount and the cable entry point, consolidating connections and keeping moisture out of vulnerable terminations. This is a cable-management component, not a camera — it exists to solve the specific problem of water ingress at the junction where cables enter a dome housing.
Key Features
- Aluminum alloy construction: Rigid, corrosion-resistant frame tolerates outdoor temperature swings and UV exposure without warping or rust — critical on rooftop or perimeter mounts where the box sits exposed for years.
- IP67 weatherproofing: Meets international dust and water ingress standards — protects against rain spray, humidity, and light spray, but not continuous submersion. Meaningful for most outdoor and semi-indoor (covered loading docks, warehouse overhangs) deployments.
- Dual outlet configuration with side and bottom cable routing: Allows you to choose entry/exit points based on your actual mounting orientation. A dome mounted flush against a soffit may route cables downward; one on a pole may route them sideways. This flexibility eliminates forced re-routing during field installation.
- Interchangeable bottom waterproof cover: Supports different installation scenarios without requiring a second part number. Swap the cover to adapt the box's sealing footprint as your cable plan changes during commissioning.
- Side gland nut for secure cable entry: Provides a threaded termination point for standard M20 or similar cable glands, ensuring consistent strain relief and seal integrity across multiple installers.
- Black finish: Blends visually with typical black dome housings and pole mounts, reducing visual impact in aesthetic-conscious environments like retail or campus settings.
Integration & Compatibility
The CBMB is specified for Hikvision dome cameras and compatible with standard dome camera cable configurations (power, Ethernet, or combination). It accommodates typical M20 cable glands and works in commercial surveillance networks, industrial facilities, and outdoor perimeter deployments where cable entry points need environmental protection. Install it between the mounting bracket and the camera dome to manage the transition from outdoor cable runs to protected enclosure.
Applications
- Commercial and retail surveillance networks requiring weatherproof cable consolidation.
- Industrial facility monitoring on exposed mounting surfaces.
- Outdoor perimeter security systems with long cable runs from entry points to camera domes.
- Multi-camera deployments where cable management reduces visible clutter and labor during commissioning.
- Weather-exposed installation environments (parking lots, loading docks, rooftops) where water and dust ingress risk is real.

Frequently Asked Questions
Q: Does the CBMB work with non-Hikvision dome cameras?
A: The CBMB is engineered specifically for Hikvision dome camera mounting patterns and cable configurations. Compatibility with third-party domes depends on matching bracket and cable dimensions. Verify mount compatibility before purchase.
Q: Can I use the CBMB indoors?
A: Yes. IP67 is useful indoors too — it protects against humidity, condensation, and accidental water spray in environments like data centers, server rooms, or facilities near wash-down areas. Not required for dry indoor office ceilings, but not harmful.
Q: What's the temperature operating range?
A: Aluminum alloy tolerates typical outdoor temperature swings (-40°C to 60°C / -40°F to 140°F). Refer to the datasheet for exact specifications. Confirm with your camera's operating range, as the CBMB is a passive component and won't affect camera thermal limits.
Q: What size cables does the CBMB accept?
A: The side gland nut accommodates standard M20 cable glands, which typically seal cables from 6–12mm diameter. Verify your cable bundle diameter matches available gland sizes before ordering.
Q: Is the CBMB included with Hikvision dome cameras?
A: No, the CBMB is a separate accessory. It's optional but recommended for outdoor and semi-outdoor installations where cable entry points are exposed to moisture.
Q: How do I install the CBMB?
A: Mount the CBMB between your dome camera bracket and the camera housing. Route cables through the side or bottom outlets using the gland nut and interchangeable cover. Secure with included hardware and ensure the waterproof cover is sealed before commissioning.

The CBMB is a straightforward but essential accessory if you're mounting Hikvision domes outdoors or in semi-exposed environments. The IP67 rating and dual outlet design solve a real integration problem: water ingress at cable entry points. Too many field installations skip this step and end up troubleshooting intermittent connection failures months later. The aluminum construction won't rust, and the interchangeable bottom cover means you're not locked into a single cable routing orientation during commissioning.
Technical Highlights:
- IP67 weatherproofing: Protects against rain and spray, eliminating moisture as a source of corrosion and electrical faults at the junction box. Not full submersion protection, but adequate for covered loading docks, rooftop eaves, and perimeter poles.
- Aluminum alloy frame: Won't corrode or warp under UV and temperature cycling. Matters on multi-year outdoor deployments where plastic housings degrade or steel rusts.
- Dual outlet (side + bottom) with interchangeable cover: Eliminates forced re-routing during field installation. Choose the cable path that matches your actual bracket and dome orientation without custom fabrication.
Deployment Considerations:
- The CBMB is designed for Hikvision dome cameras specifically. Verify bracket and cable dimensions before deploying on third-party domes — mismatched gland sizes force field improvisation.
- M20 gland nut standard is typical, but confirm your cable bundle diameter (6–12mm typical) fits available glands. Oversized cables require upsizing to M25, which may not be included.
Deploy the CBMB on any outdoor or semi-outdoor Hikvision dome installation where cables run exposed before entry into the housing. It's cheap insurance against water intrusion and connector corrosion — typical ROI on a $50–80 accessory is immediate if it prevents even one field visit to replace a corroded power connector six months post-commissioning.
