Hikvision CB155 Junction Box, White
The CB155 is a surface-mounted junction box engineered to shield cable terminations and connection points in outdoor surveillance installations. Built from aluminum alloy with surface spray treatment and rated IP66, it provides the sealed environment needed to keep moisture, dust, and environmental contaminants away from vulnerable wiring without requiring a separate enclosure redesign.
Key Features
- IP66 Rating (Dust-Tight, Water-Jet Resistant): Direct rain spray and dust won't penetrate the sealed housing—this level of protection is mandatory for outdoor cable runs and junction points where cables terminate or branch. If you need full submersion protection (e.g., below-water installations), you'll need IP67 or higher; IP66 handles exposed outdoor wall mounts reliably.
- Aluminum Alloy Construction with Surface Spray Treatment: Aluminum resists corrosion better than steel in salt air and humid climates, and the spray coating adds an extra barrier against oxidation. This means less maintenance and longer service life in challenging environments—critical for deployments where repainting or replacement is logistically difficult.
- Waterproof Gasket Seal: A gasket ensures that when the cover closes, water and dust stay out. Gaskets degrade over time in UV-heavy outdoor installations, so plan for periodic inspection (annually in harsh climates) to keep the seal effective.
- Lightweight at 0.66 lbs: Low weight reduces installation stress on wall anchors and makes single-technician mounting feasible without additional support hardware. This is meaningful when running multiple cable runs across a large facility—labor and bracket costs add up fast.
- Surface-Mounted, Flat-Wall Installation: The CB155 mounts directly onto flat exterior surfaces (concrete, stucco, metal panels). No need to cut into walls or run concealed conduit. This reduces installation time and avoids structural compromises that can weaken building envelopes in freeze-thaw cycles.
- Hikvision Surveillance System Compatibility: The CB155 is designed for Hikvision IP cameras and surveillance infrastructure. It integrates seamlessly with the cable management practices common in Hikvision deployments, simplifying procurement and standardization across multiple sites.
Integration & Deployment Context
The CB155 fits into any outdoor surveillance cable topology where junction points or terminations are exposed. Common deployment scenarios include retail exterior corners where multiple camera runs converge, industrial facility fence lines requiring consolidated cable management, municipal traffic monitoring installations, and residential perimeter security where cable runs cross eaves or fascia. Because it's accessory-class, the CB155 does not perform active signal conditioning, amplification, or filtering—it is purely a protective enclosure. Pair it with appropriate network video recorders and PoE switches sized for your camera power budget and bandwidth requirements.
In cold climates, ensure that interior gasket temperature doesn't cause condensation inside the box. Sealed enclosures can trap moisture if temperature differentials are extreme; small drainage holes or a desiccant packet may be warranted in sub-zero deployments. Verify local electrical codes before installation—some jurisdictions classify junction boxes as electrical components and may require bonding or grounding of the aluminum housing.
Frequently Asked Questions
Q: Is the CB155 suitable for underground cable runs?
A: No. The IP66 rating protects against water spray and dust, but not submersion. Buried cable runs require conduit or ductwork rated for underground installation. The CB155 is designed for above-ground, exposed outdoor wall mounts.
Q: Can I wall-mount the CB155 on a metal surface?
A: Yes, the surface-mount design works on flat metal panels. Ensure the metal surface is clean and use corrosion-resistant fasteners (stainless steel anchors recommended) to avoid galvanic corrosion between the aluminum housing and the mounting substrate.
Q: Does the CB155 require grounding?
A: Local electrical code varies. Aluminum enclosures in some jurisdictions must be bonded to ground for safety. Consult your local inspector before installation. If grounding is required, use a separate bonding conductor—do not rely on the cable shield.
Q: How often should I inspect the gasket?
A: At least annually in outdoor installations, or after heavy storms. UV exposure degrades rubber gaskets over 12–24 months. If the gasket cracks or loses flexibility, replace it to maintain IP66 integrity.
Q: Is the CB155 compatible with non-Hikvision cables?
A: Yes. The CB155 is a generic junction box. Any industry-standard RJ-45, coaxial, or power cable can run through it. Hikvision designed it specifically for Hikvision systems, but it functions as a passive enclosure for any cable type.

The CB155 is a straightforward, no-nonsense accessory that solves a real problem in outdoor surveillance: water and dust getting into cable terminations. The IP66 rating is the key specification here—it means the box handles direct rain spray and dust jets without letting moisture inside. For outdoor cable consolidation points, that's the difference between a dry splice and a corroded connector that fails during a storm.
Technical Highlights:
- IP66 Environmental Sealing: Dust-tight and water-jet resistant. In real deployments, this protects RJ-45 connectors, power terminals, and coaxial splices from the moisture that causes the majority of outdoor cable failures. If you're running cables across exposed wall runs or fence lines, IP66 is the baseline; anything less will cost you in field service calls.
- Aluminum Alloy with Spray Coating: The material choice matters. Bare aluminum corrodes in coastal environments within months. The spray treatment extends that life significantly—18–24 months of UV and salt exposure before visible degradation in salt-air zones. For non-coastal outdoor installations, this housing will outlast the camera by a factor of two.
- 0.66 lbs Weight and Surface-Mount Design: Low weight and direct wall mounting eliminate the need for heavy-duty brackets or conduit supports. This reduces installation cost on large multi-site rollouts where you're mounting dozens of junction points. Standard masonry anchors or self-tapping fasteners are sufficient.
Deployment Considerations:
- Gasket Maintenance is Real: The waterproof gasket is your primary defense against moisture ingress. UV exposure degrades rubber gaskets in 12–24 months in direct sunlight. Inspect annually or after heavy rain events; replacement gaskets are inexpensive, but a failed gasket will flood your cable bundle. Build this into your preventive maintenance schedule.
- Condensation Risk in Extreme Temperature Swings: Sealed enclosures in sub-zero climates can trap moisture if warm cables inside create temperature differentials. In freeze-thaw environments, consider adding a small silica desiccant pack inside the box during winter shutdowns. This isn't a box defect—it's how physics works with sealed enclosures.
- Check Local Electrical Code Before Installing: Some jurisdictions classify aluminum junction boxes as electrical enclosures and require bonding to ground. This adds one extra conductor but is mandatory for compliance. Verify before you design your cable run.
The CB155 makes sense for any outdoor cable consolidation point where you're running multiple Hikvision cameras or mixed surveillance infrastructure into a common junction. It's not glamorous, but it's a practical defense against the weather—deploy it on exposed eaves, fence lines, or roof penetrations where cables are vulnerable, and it will reduce field service costs and improve system uptime significantly.
