Hikvision TV2713D-4MPIR Mega-pixel Auto-Iris Lens

Model: TV2713D-4MPIR

Who This Is For

When flexible focal length combined with automatic iris control is the priority, the Hikvision TV2713D-4MPIR is the lens installers reach for. Designed for CS-mount box cameras that require a field-swappable or upgrade lens, this 2.7-13mm varifocal covers everything from wide entry-point monitoring to tighter identification distances on a single unit - without returning to site to swap optics. The DC auto-iris drive makes it practical for installations that move between bright outdoor light and shaded or interior environments, such as undercover car parks, warehouse entries, and covered loading bays. At F1.2, low-light sensitivity is strong for a varifocal lens at this price point. Installers specifying 4MP box camera builds for commercial or light industrial sites, and integrators who need a lens that handles variable lighting without manual intervention, are the primary buyers for this model.

What This Product Actually Does

Who Buys This Model

• CCTV installers building box camera systems: Specifying a CS-mount 4MP varifocal with auto-iris for commercial box camera enclosures where the camera body ships without a lens.
• Integrators upgrading existing installations: Replacing a lower-resolution or fixed-focal lens on a box camera that already has a CS-mount body, to lift resolution or add auto-iris functionality without replacing the entire camera.
• Industrial site and warehouse managers: Specifying covered entry or loading dock coverage where the scene transitions between direct outdoor light and darker interior areas - conditions where DC auto-iris earns its keep.
• Car park and facility operators: Using box cameras in external enclosures at boom gates or pedestrian entries where the 2.7-13mm range covers both wide-view and tighter vehicle plate framing on the same lens.

Honest Assessment

The TV2713D-4MPIR does the job it is designed for well: a compact, light CS-mount varifocal with DC auto-iris, F1.2 aperture, and a 4MP-rated optical path. The 2.7-13mm range is genuinely flexible for most commercial monitoring distances, and the auto-iris removes a common failure point in scenes with mixed or changing light. At 80.6g and Φ43.6 x 56.3mm, it fits neatly into standard box camera enclosures without clearance issues. This is a lens for CS-mount box cameras only - it is not compatible with integrated dome, turret, or bullet cameras that use proprietary fixed-lens modules. It also does not include a camera body, power supply, or mounting hardware. Buyers who need a complete camera unit rather than a standalone lens should look at integrated camera models available through Security Australia. For installations requiring motorised remote zoom and autofocus from the NVR interface, a motorised varifocal lens with a compatible camera body is a better fit than this manually adjusted model.

Before You Buy

Quick Fit Check

• Good match if: You are building or upgrading a CS-mount box camera installation and need a single lens that covers both wide overview and closer identification framing - the 2.7-13mm range handles both without a lens swap.
• Good match if: Your installation is in a mixed-light environment such as a covered car park entry or loading dock, where the DC auto-iris at F1.2 will automatically compensate for light changes and avoid blown-out or underexposed frames.
• You may need a different model if: You need remote zoom and focus adjustment from the NVR or VMS without physical access to the camera - motorised varifocal lens and camera combinations on the Security Australia site are better suited to that requirement.

Real-World Scenarios

How It Compares

• Choose this if: You need a compact CS-mount varifocal with DC auto-iris and a 4MP-rated optical path, particularly where scenes involve mixed or rapidly changing light levels that would overload a manual iris lens.
• You may need a different model if: Remote zoom and focus control from the NVR or VMS interface is required - a motorised varifocal lens and compatible camera body combination is better suited, as this model requires on-site manual ring adjustment.
• Pairs well with: A CS-mount Hikvision box camera body with DC auto-iris support, a weatherproof box camera enclosure, and an IR illuminator for low-light outdoor use.

Common Questions

1. Does this lens include a camera body?

   No. The TV2713D-4MPIR is a standalone lens only - it does not include a camera body, housing, power supply, or any other component. It is designed to be fitted to a compatible CS-mount camera body. Buyers who need a complete camera unit should look at integrated box camera or bullet camera models on the Security Australia site.

2. Will this lens work with any CS-mount camera, or only Hikvision?

   It will physically fit any CS-mount camera body, but the DC auto-iris function requires the camera body to have a DC-drive iris connector and support that iris control mode. Hikvision box cameras with a DC auto-iris input are the primary compatible platform. Use on non-Hikvision bodies is possible if the camera supports DC-drive iris control - confirm in the camera body's specification sheet before ordering.

3. What is the difference between DC auto-iris and video auto-iris (AI)?

   DC auto-iris receives a direct control voltage from the camera body to drive the iris motor. Video auto-iris (AI) derives its control signal from the video output of the camera. These are not interchangeable - using a DC-drive lens on a video-iris camera body, or vice versa, will result in incorrect or unstable exposure. The TV2713D-4MPIR is DC-drive only. Confirm your camera body's iris drive type before purchase.

4. Does the 4MP rating mean this lens will work on a higher-resolution sensor?

   No. The 4MP rating indicates the optical resolution the lens is designed to resolve. Using a 4MP-rated lens on an 8MP or higher sensor means the lens becomes the limiting factor - the sensor will not receive enough optical detail to use its full resolution. For sensors above 4MP, a lens rated to match or exceed the sensor resolution is required.

5. Will this lens work outdoors in Australian summer heat?

   Yes, within an enclosure. The 60°C upper operating temperature covers standard ambient outdoor temperatures across Australia, but the lens is not weatherproof on its own - it must be housed inside a rated IP-class box camera enclosure for outdoor use. Unventilated metal enclosures in direct sun can exceed ambient temperature, so verifying enclosure thermal performance is recommended for installations in extreme heat zones.

6. Can zoom and focus be adjusted remotely after installation?

   No. The TV2713D-4MPIR uses manual zoom and focus rings only. Both adjustments require physical access to the lens after mounting. For installations where camera positions are difficult to access or where zoom and focus need to be adjusted from the NVR or software interface, a motorised varifocal lens with compatible camera body is a more practical option.
