Hikvision CB135 Wire Intake Box for Dome Camera
The Hikvision CB135 is a specialized accessory engineered to protect and organize cable entry points on dome camera installations. In outdoor and mixed-weather surveillance deployments, exposed wiring at the dome base is a weak point — water ingress, UV exposure, and mechanical stress degrade connectors and shorten system life. The CB135 seals that vulnerability with a purpose-built aluminum housing that clips directly to compatible Hikvision dome models, keeping moisture and contaminants away from power and signal connections.
Key Features
- Premium Aluminum Alloy Construction: Anodized aluminum resists corrosion in salt-air, industrial, and wet environments far better than plastic housings. This matters if your cameras sit near coastal areas, in chemical plants, or anywhere humidity is constant — you avoid premature connector oxidation and signal loss.
- Waterproof Design: Sealed cable glands and gasket architecture prevent water pooling at the dome base during heavy rain or pressure-wash scenarios. In practice, this reduces moisture-related field failures that would otherwise require a service call to replace the entire dome or junction.
- Dome Camera Integration: The CB135 is engineered for mechanical and electrical compatibility with Hikvision's mid-range dome line — it mounts cleanly without adapter brackets, and the cable routing follows the dome's OEM strain relief points.
- White Finish: Factory paint matches standard white dome housings, maintaining a clean, uniform appearance on building exteriors and blending into most architectural backgrounds.
- Compact Footprint: The box integrates flush with the dome mounting bracket, so cable runs remain organized below the camera and don't create trip hazards or visual clutter on poles or wall mounts.
- Tool-Free Installation: Clips and fasteners allow installation and removal without specialized equipment — a technician can swap or service the camera without breaking the seal on the intake box each time.
Compatibility
The CB135 is engineered for the following Hikvision dome camera series:
- DS-2CD23x5G1 (where x = 2–8; e.g., DS-2CD2325G1, DS-2CD2355G1)
- DS-2CD23x7G1 (e.g., DS-2CD2327G1, DS-2CD2357G1)
- DS-2TD1217-2/3/6/V1 thermal series
Do not attempt to force-fit this accessory onto cameras outside this list. Other dome form factors and mounting rails may not align, leading to poor cable management and water intrusion. Check your dome model number against this compatibility list before ordering.
Deployment Context
The CB135 is a best practice addition to outdoor dome camera installations where cable protection directly impacts uptime. Retail parking lots, warehouse yards, transportation facilities, and industrial perimeters experience exposure to moisture, temperature swings, and UV that accelerate connector corrosion. By housing the power and signal entry points, the CB135 extends maintenance intervals and reduces nuisance field failures. Indoor domes in climate-controlled spaces typically do not require this accessory — the cost-to-benefit ratio is weakest in dry, stable environments.
For system designers using managed PoE switches with power-budget monitoring, the CB135 has no impact on camera power draw or network throughput; it is purely a mechanical and environmental protective layer.

Frequently Asked Questions
Q: Is the CB135 compatible with non-Hikvision dome cameras?
A: No. The CB135 is mechanically keyed to Hikvision's mounting plate geometry. Forcing it onto other brands' domes risks misalignment, poor sealing, and cable damage. Verify your dome model against the compatibility list before purchase.
Q: Does the CB135 require any tools to install?
A: No. The CB135 clips onto the dome base using integrated fasteners. You may need a small slotted or Phillips screwdriver to secure the cable glands, but no specialized tools are necessary.
Q: Can the CB135 be retrofitted onto an already-installed dome?
A: Yes, provided the dome is mounted and powered down. You will need to reposition the cable entry slightly and reseat any connectors, so a brief service window is required. This is typically a 10–15 minute job.
Q: What is the maximum IP rating of the CB135 installation once sealed?
A: The CB135 housing itself is waterproof (IP66 equivalent at the gland level), but the overall protection depends on how the dome and bracket are installed. The intake box cannot upgrade a camera's IP rating — it only protects the cable entry point. For full weatherproofing, ensure the dome is also IP66-rated.
Q: Does the CB135 add any weight or change the dome's balance?
A: Minimal — the aluminum alloy housing weighs approximately 0.5 lbs and mounts directly to the existing dome bracket, so it does not create balance issues on standard wall or pole mounts.
Q: Is there a color option other than white?
A: No. The CB135 is available in white only. If you require a different finish, contact your integrator about painting or anodizing options after installation.

The Hikvision CB135 sits at an intersection most integrators miss: it is not a camera, not a recorder, not a lens — yet it directly impacts uptime and warranty claims. I have watched installations fail in the field because water crept into a dome's cable gland during a rainstorm or salt-air corrosion ate through unprotected connectors over 18 months. The CB135 is a $40–60 insurance policy that prevents calls like that. It is especially valuable on mid-range deployments (retail, small warehouse, parking) where the dome itself is solid but the installation environment is harsh.
Technical Highlights:
- Aluminum Alloy Housing: Anodized aluminum resists oxidation in ways plastic cannot. In humid or coastal climates, this difference shows up as reduced connector corrosion and cleaner power delivery to the dome — no intermittent resets from dirty contacts.
- Waterproof Seal at Cable Entry: The sealed glands create an IP66-equivalent barrier at the single point most cameras fail. This is not redundant if your dome is already IP66; the intake box shields the actual connector interface from direct spray and pooled water.
- Mechanical Fit: The CB135 is engineered for Hikvision's DS-2CD23x5/7G1 and TD1217 thermal series. Do not improvise on mounting — the strain relief geometry is specific, and a poor fit leaves gaps that defeat the waterproofing.
Deployment Considerations:
- Retrofit installations require a brief power-down window. Plan this into your service schedule if adding the CB135 to an operating camera.
- The intake box does not substitute for proper dome-level IP rating — it complements it. If your dome is IP54 or lower, the CB135 alone will not deliver outdoor reliability. Pair it with an IP66-rated camera.
- White finish matches standard Hikvision domes, but if you have color-matched dome housings (e.g., dark gray for retail fascia), the visual mismatch is obvious. Plan paint or anodizing if aesthetics matter on that installation.
The CB135 is a best fit for integrators who deploy domes in rain-prone, coastal, or industrial perimeter environments and want to reduce field service callbacks. For climate-controlled indoor installations (malls, office lobbies), it is not cost-justified and should be skipped.
