Hikvision CB135B Wire Intake Box for Dome Camera
The Hikvision CB135B is a weatherproof cable management accessory purpose-built to protect and organize wiring connections on compatible Hikvision dome cameras. If you're deploying cameras in outdoor or semi-outdoor environments where exposed cable runs are a liability — physically, electrically, and aesthetically — the CB135B solves a real installation problem: controlling moisture ingress at the cable entry point while keeping connector terminations organized and accessible.
Why This Accessory Matters
Cable entry is a weak point in any outdoor surveillance installation. Water follows paths. Aluminum construction paired with a waterproof design means the CB135B resists corrosion and keeps rain, dust, and debris away from the connector interfaces where failures most often occur. At 0.62 lbs, it's light enough that it won't stress mounting hardware or add noticeable load to the camera bracket — relevant when you're dealing with multiple cameras on a single pole or wall surface.
The black finish is functional as well as aesthetic: it matches the appearance of Hikvision's modern dome housing without standing out visually on buildings or structures.
Compatibility & Integration
The CB135B is designed for these Hikvision dome camera series:
- DS-2CD23x5G1 series — covers the 235/245/255 variants commonly deployed in general surveillance roles
- DS-2CD23x7G1 series — includes the 237 thermal-hybrid and multi-sensor variants
- DS-2TD1217-2/3/6/V1 series — the turret-dome thermal line for perimeter and night-critical applications
Before ordering, cross-reference your camera model against this list. While the form factor may appear compatible with other dome housings, fitment and cable routing are optimized for these specific models, and forced installation on non-compatible cameras risks damaging the camera or the intake box itself.
Installation Context
The CB135B supports both fixed camera installations and temporary deployments. It's particularly useful in:
- Rooftop and wall-mounted arrays where multiple cables need separation and weather shielding
- Warehouse and loading dock environments where dust and splash are routine
- Industrial or high-vibration sites where cable stress relief reduces connector fatigue over time
- Retrofit and upgrade work on existing dome camera installations where cable management standards have tightened
When planning a multi-camera deployment, factor in one intake box per camera if outdoor cable runs are exposed — they're inexpensive enough to include in the bill of materials, and they extend the mean time between failures on the electrical side.

Frequently Asked Questions
Q: Does the CB135B fit indoor dome cameras?
A: The CB135B is optimized for outdoor and semi-outdoor use where waterproofing matters. Indoor installations may not need the weatherproof protection, but there's no mechanical barrier to using one — just confirm your specific camera model is on the compatibility list first.
Q: Can I use the CB135B with non-Hikvision dome cameras?
A: No. The intake box is designed for Hikvision's specific dome form factors and cable routing. Cross-brand fitment is not guaranteed and could result in poor water sealing or physical interference.
Q: What's the waterproof rating?
A: The CB135B is rated waterproof, which typically means it resists rain, spray, and moisture from outdoor weather. Submersion or high-pressure washdown is not recommended — consult the datasheet for exact environmental limits.
Q: Do I need a separate mounting template for installation?
A: The CB135B mounts directly to compatible Hikvision dome housings. No additional template is typically required, but follow the camera installation manual for precise routing instructions.
Q: How many cables can the CB135B manage at once?
A: The intake box is designed to handle standard PoE and alarm/audio connections typical on Hikvision domes (usually 1–3 connector entries). Do not overload or force multiple cables that exceed the design intent.

The CB135B is a small but purposeful addition to any outdoor Hikvision dome deployment. Cable management and weather sealing at the connector interface sound unglamorous, but they're among the most common failure points in field installations. At 0.62 lbs and aluminum construction, this intake box introduces no meaningful stress on mounting structures while delivering real protection against the elements.
Technical Highlights:
- Aluminum alloy material: Corrosion resistance in salt-air, UV-exposed, and high-humidity environments — important for coastal, agricultural, or industrial sites where steel brackets would fail within 18–24 months.
- Waterproof design: Keeps rain and spray off connector terminations, the single most vulnerable point in outdoor cabling. Reduces moisture-related intermittent failures and connection degradation.
- Lightweight (0.62 lbs): Minimal added load on dome mounts and pole brackets — especially relevant when you're stacking multiple cameras on a single arm or when dealing with undersized legacy mounting hardware.
Deployment Considerations:
- Fitment is specific to the three Hikvision series listed — verify part compatibility before ordering. Forcing this onto a non-compatible dome will not seal properly and defeats the purpose.
- The CB135B protects the cable entry but does not replace proper cable routing and strain relief. Budget time during installation to dress cables neatly and avoid sharp bends near the connector.
Use the CB135B on every outdoor or semi-outdoor Hikvision dome installation where cable runs are exposed to weather. It's cheap insurance against water ingress, corrosion, and the unplanned truck rolls that come with field failures in the third year of operation.
