Hikvision PC155B Pendant Cap for Dome Camera
The Hikvision PC155B is a professional-grade mounting accessory engineered for secure ceiling installation of compatible dome cameras. Built from aluminum alloy with a waterproof design, this pendant cap addresses a specific installation scenario: flush ceiling deployment where you need a compact, durable neck between the camera body and the ceiling outlet. It's purpose-built for both indoor and outdoor surveillance environments where environmental sealing matters.
Key Features
- Aluminum Alloy Construction: Resists corrosion in humid, salty, or chemically aggressive environments — a meaningful factor in warehouses, coastal facilities, or industrial settings where standard steel hardware degrades quickly.
- Waterproof Design: Sealed construction prevents water ingress into the junction between camera and ceiling, critical for outdoor installations or areas subject to washdown or high-humidity spray. Skip this if you need full submersion protection — that requires additional gaskets or enclosure-level IP67 ratings.
- Pendant-Style Ceiling Mount: Designed for flat surface mounting with a neck-down form factor. Mounts directly to standard ceiling outlet boxes, minimizing the visible footprint and creating a cleaner appearance than bracket-style alternatives.
- 1.4 lbs Weight Capacity: Supports typical dome camera assemblies up to 1.4 pounds. If your camera body plus lens assembly exceeds this — common with larger varifocal domes or PTZ units — you'll need a reinforced pendant or wall-mount bracket instead. Verify your camera's actual weight before committing.
- Wide Dome Camera Compatibility: Engineered to fit various Hikvision dome models and many third-party domes following standard pendant-cap thread and dimension conventions. Always verify thread pitch and bore diameter against your specific camera's mounting interface.
- Black Anodized Finish: Reduces glare and blends with typical ceiling tile and infrastructure, improving video quality by minimizing reflection into the lens.
Integration & Compatibility
The PC155B works with any dome camera featuring a standard M22 or equivalent pendant-cap thread interface. It's passive — no electronics, no power draw, no firmware. Installation is straightforward: thread the camera's mounting stud into the PC155B's threaded bore, then secure the pendant to your ceiling outlet box with the supplied fasteners. Verify torque specs in your camera's installation manual to avoid cross-threading the aluminum bore.
When to Choose a Different Accessory
If you're mounting a heavier dome assembly (above 1.4 lbs), consider a reinforced pendant cap or a wall-mount bracket in the same family that offers higher weight capacity. For recessed ceiling installations or environments requiring tool-free quick-disconnect, explore alternative mounting styles from Hikvision's accessory catalog.
Deployment Context
The PC155B is typical for retail, office corridors, warehouse aisles, and light-duty outdoor monitoring where you need a compact, sealed neck between the dome and ceiling. It's not a substitute for full environmental enclosures — if your camera must survive direct spray or salt-fog corrosion, add an IP67-rated dome housing. For indoor drop-ceiling grids, this pendant works well; for recessed architectural ceilings, you may need a different form factor.
Frequently Asked Questions
Q: Is the PC155B compatible with my Hikvision 2MP turret camera?
A: The PC155B is designed for dome cameras with standard pendant-cap mounting threads. Turret cameras typically use wall-mount or pole-mount brackets, not pendant caps. Verify your turret's mounting interface before ordering.
Q: Can I use the PC155B outdoors?
A: Yes. The aluminum alloy and waterproof design handle outdoor weather, but it's not rated for submersion or high-pressure wash-down. For coastal or salt-spray environments, the aluminum will eventually corrode; consider stainless steel alternatives if your site has aggressive conditions.
Q: What's the maximum camera weight the PC155B supports?
A: 1.4 lbs. Heavier domes require a reinforced pendant cap or wall-bracket accessory with higher load rating.
Q: Do I need tools to install the PC155B?
A: Yes. You'll need a wrench or hex key to thread the camera mounting stud into the PC155B and to secure the pendant to the ceiling outlet box. Refer to your camera's installation guide for the correct torque specification.

The PC155B is a straightforward accessory — no surprises, no hidden limitations — but it's also easy to overlook during dome camera procurement. I've seen integrators spec the camera, forget the mounting hardware, and then scramble for a compatible pendant when installation begins. The PC155B eliminates that friction if you're deploying standard Hikvision domes on flat ceilings.
Technical Highlights:
- 1.4 lbs weight capacity: Tight enough to force a second thought if you're installing a varifocal dome over 1.2 lbs. Weigh your camera assembly before ordering — varifocal optical units add mass fast.
- Aluminum alloy construction: Corrosion-resistant in typical HVAC, retail, and light industrial environments. In salt-fog or aggressive chemical spray zones, aluminum degrades within 2–3 years; upgrade to stainless steel variants if corrosion is a concern.
- Waterproof sealed design: Meaningful for wet areas (kitchens, bathrooms, exterior overhangs) where moisture can wick into the junction between camera and ceiling. Not a substitute for dome-level IP67 ratings — this protects the mechanical joint, not the electronics.
Deployment Considerations:
- Thread pitch matters. Verify the PC155B's bore matches your camera's mounting stud. Mismatched threads will either strip or cross-thread — a problem that only reveals itself during commissioning, not in the lab.
- Ceiling outlet boxes must be rated for at least 1.4 lbs of hanging load. Most standard electrical boxes are, but pre-fab or lightweight acoustic ceiling systems sometimes aren't. Confirm your structural attachment point before final install.
Best fit: roll-out retail and warehouse deployments on drop ceilings or standard drywall, where simplicity and speed matter. Skip it for heavy-optic or specialized mounting scenarios — that's where you pivot to alternative brackets or wall mounts.
