Hikvision HIK-TV0550D-MPIR 3MP Lens 1-2.7inch, CS mount 5-50mm

Model: HIK-TV0550D-MPIR

Who This Is For

For installers and integrators who need to retrofit or upgrade a CS-mount camera body with a high-resolution varifocal lens, the Hikvision HIK-TV0550D-MPIR delivers a 5-50mm manual zoom range rated to 3MP resolution in a compact metal housing. This lens is the right call when the camera body is already in place - or when a project demands a specific focal length that no fixed-lens model covers. The 10x manual zoom range makes it especially suited to applications where the monitored distance is uncertain at design stage: long driveways, perimeter fences, car parks, and building approaches where the installer needs to dial in framing on-site rather than commit to a fixed angle during procurement. The automatic aperture handles lighting shifts without manual intervention, making it practical for mixed indoor-outdoor deployments where ambient light changes through the day.

What This Product Actually Does

Who Buys This Model

• Security integrators replacing worn or mismatched lenses: Box camera bodies outlast their original lenses in many installations. The HIK-TV0550D-MPIR provides a direct CS-mount replacement rated to 3MP for any Hikvision box camera body that has been upgraded from an older 1MP or 2MP sensor.
• Installers covering variable-distance perimeters: Fence lines, loading docks, and car park entries where the exact standoff distance to the coverage zone was not confirmed at design stage. The 5-50mm range allows final framing to be locked in during commissioning without returning to procurement.
• Industrial site and warehouse operators: Sites running Hikvision box cameras in fixed outdoor housings where the lens must handle temperature extremes from -20 degrees C to +60 degrees C and maintain IR focus correction through the full focal range at night.
• Technical buyers specifying custom camera builds: Projects where a box camera body is selected separately from the lens to achieve a specific combination of sensor, housing, and focal range not available in any off-the-shelf integrated unit.

Honest Assessment

The HIK-TV0550D-MPIR does two things well: it covers an unusually wide zoom range (5-50mm) in a single barrel, and it does so with optics rated to 3MP and corrected for IR focus shift. For installers who need on-site zoom flexibility without committing to a fixed focal length at the design stage, that combination is genuinely useful. The automatic aperture also removes one variable from outdoor deployments where lighting changes through the day. What it will not do is replace an integrated varifocal camera with motorised zoom - there is no remote zoom or focus capability, and both must be adjusted physically at the lens. It also requires a compatible CS-mount box camera body and housing, which are separate purchases. If the installation needs a self-contained outdoor unit with motorised remote zoom, a PTZ or motorised varifocal camera is a better fit - both are available through Security Australia. This lens is a component purchase, not a complete solution.

Before You Buy

Quick Fit Check

• Good match if: You are building or upgrading a CS-mount Hikvision box camera and need a single lens that covers both wide-area and long-distance framing without changing glass - the 5-50mm manual zoom range handles both in one barrel.
• Good match if: Your installation runs IR illumination at night and you need confirmed focus stability after dark - the IR-corrected optics prevent the focal shift that affects non-corrected varifocal lenses in night mode.
• You may need a different model if: The camera is mounted at height and you need to adjust zoom or focus remotely after installation - a motorised varifocal or PTZ camera with remote zoom control is a better fit for that requirement.

Real-World Scenarios

How It Compares

• Choose this if: You need a single lens that spans from wide-angle to long-range telephoto (5-50mm) on a CS-mount body, and the zoom must be set manually at commissioning with no ongoing remote adjustment required.
• You may need a different model if: The camera is at height or in an inaccessible location and zoom or focus needs to be adjusted remotely after installation - a motorised varifocal integrated camera or PTZ is the right product type for that scenario.
• Pairs well with: A CS-mount Hikvision box camera body in a fixed outdoor weatherproof housing, combined with an external IR illuminator for longer-range night coverage beyond the ambient IR of the camera body itself.

Common Questions

1. Will this lens fit my existing Hikvision box camera?

   Yes, if your camera body uses a CS mount. The HIK-TV0550D-MPIR is a CS-mount lens and fits directly onto any CS-mount Hikvision box camera body without an adapter. If your body uses a C mount, a 5mm C-to-CS adapter ring is required - that adapter is not included with the lens.

2. Does the image stay in focus at night when IR switches on?

   Yes. The HIK-TV0550D-MPIR uses IR-corrected optics, which means the focal point does not shift when the camera transitions from visible light to infrared night mode. Standard varifocal lenses without IR correction will appear sharp during the day but lose focus after dark - this lens is built to prevent that.

3. Can I adjust the zoom remotely or does it have to be done at the lens?

   No remote adjustment is available. Both zoom (5-50mm) and focus are set manually by turning the rings on the lens barrel. This must be done physically at the camera, with the image live on a monitor, before the housing is sealed. If remote zoom adjustment is a requirement, a motorised varifocal or PTZ camera is the appropriate product type.

4. What resolution camera body should I pair this with?

   Up to 3MP. The lens is rated to resolve 3MP (2048 x 1536), so it is well matched to 1MP, 2MP, and 3MP sensor bodies. Pairing it with a 4MP or higher sensor body means the lens optics will become the limiting factor on image detail - for sensors above 3MP, a lens with a higher resolution rating is recommended. This lens is part of the Security Australia range alongside compatible Hikvision camera bodies.

5. Does this lens work in outdoor installations?

   Yes, provided it is installed inside a weatherproof camera housing rated for outdoor use. The lens itself is metal-bodied and rated from -20 degrees C to +60 degrees C, which covers most Australian outdoor conditions, but the lens does not carry its own IP weather rating - outdoor protection comes from the camera housing it is mounted into.

6. Does the automatic aperture require a specific connection from the camera body?

   Yes. The DC auto-iris requires the camera body to output a DC auto-iris control signal, typically via a 4-pin connector on the lens. Most Hikvision box cameras with a lens drive output support this. If your camera body does not provide this signal, the aperture will remain in a fixed position and will not respond to lighting changes automatically - check your camera body's specification before purchasing.

7. What sensor size is this lens designed for?

   The lens is designed for 1/2.7-inch sensors and smaller. Camera bodies with larger sensors - such as 1/2-inch or 1/1.8-inch - may see light falloff (vignetting) at the corners, particularly at wider focal lengths. Confirm your camera body's sensor size matches 1/2.7-inch or below before specifying this lens.
