Product Overview
Upgrading an existing coaxial CCTV site to 8MP resolution no longer requires a full recabling project. The DS-2CE78U7T-IT3F is a TVI 4.0 outdoor turret camera from Hikvision that delivers 3840 x 2160 (4K) video over the same coaxial infrastructure already in the ground. Equipped with a 2.8mm fixed lens and Smart IR rated to 60 metres, it suits wide-angle outdoor coverage across driveways, building perimeters, car parks, and entry points where existing cable runs are already in place. Featuring 130dB true WDR and ultra-low light capability, it handles scenes with mixed lighting conditions or near-complete darkness without overexposing bright areas or losing shadow detail. It also includes 3D DNR to suppress noise in challenging light conditions. The 4-in-1 switchable output supports TVI, AHD, CVI, and CVBS formats, giving installers flexibility across different DVR brands and generations. Rated IP67 and powered by 12VDC, this camera is built for year-round outdoor deployment.
Key Capabilities
8MP 4K Resolution over Coax
At 3840 x 2160, the DS-2CE78U7T-IT3F delivers four times the pixel count of a 1080p analogue camera. This level of detail allows faces, plates, and scene elements to be resolved from the recorded footage without needing a separate IP infrastructure.
60m Smart IR with EXIR Technology
Hikvision’s EXIR array uses a structured emitter arrangement to project even illumination across the field of view, reducing the hot-spot effect common in older IR cameras. Smart IR automatically adjusts intensity as subjects move closer, preventing washout at short range.
130dB True WDR
True Wide Dynamic Range at 130dB manages scenes where bright sunlight and deep shadow appear in the same frame, such as a shaded driveway entrance or a car park entry with direct sunlight behind approaching vehicles. Both zones remain usable in the recorded image.
4-in-1 Switchable Output
The TVI, AHD, CVI, and CVBS switchable output means this camera can be connected to a wide range of DVR brands and recorder generations. This simplifies mixed-brand site upgrades and reduces the need to replace all recorder hardware when adding or replacing cameras.
Ultra-Low Light with 3D DNR
The ultra-low light sensor retains usable colour and detail in environments well below standard lux ratings. Combined with 3D Digital Noise Reduction, the image stays clean in dim conditions, avoiding the grain and motion blur that degrade footage quality on lower-spec analogue cameras.
Best For
- Analogue Site Upgrades: The TVI 4.0 format and 4-in-1 switchable output allow existing coaxial cable runs to carry 8MP video, making this camera well suited to sites that need a resolution uplift without relaying infrastructure.
- Wide-Angle Outdoor Coverage: The 2.8mm fixed lens captures a broad scene, making it practical for open areas such as driveways, entry forecourts, building elevations, and car parks where coverage width is the priority over long-range zoom.
- Night Monitoring at Distance: With Smart IR rated to 60 metres and EXIR technology, this camera maintains consistent illumination across the scene at night, covering longer outdoor approaches without requiring supplementary lighting.
- Mixed-Lighting Environments: Sites with a combination of bright outdoor light and shaded zones, such as covered loading areas or shaded building entries, benefit from the 130dB true WDR which preserves detail across both extremes in a single frame.
Why Choose the DS-2CE78U7T-IT3F
The DS-2CE78U7T-IT3F occupies a specific position in the TVI camera market: it brings genuine 4K resolution to coaxial-based systems that would otherwise require a full IP network retrofit to achieve comparable image quality. A standard 1080p or even 5MP TVI camera cannot match the pixel density that 3840 x 2160 provides for forensic-level review of recorded footage. The 130dB true WDR goes well beyond basic digital WDR found on budget analogue cameras, delivering usable imagery in scenes with extreme contrast. The 60m Smart EXIR range and ultra-low light sensor mean performance holds up after dark without supplementary lighting. For installers and site managers looking to future-proof an existing coaxial site with a credible image quality upgrade, the DS-2CE78U7T-IT3F is available through Security Wholesalers as part of the Hikvision TVI 4.0 range.
Buyer Decision Tips
Coaxial vs IP: This camera transmits video over coaxial cable using TVI 4.0 and requires a compatible TVI, AHD, CVI, or CVBS DVR. It is not compatible with PoE NVRs or IP-based recording systems. If the site does not have existing coaxial cable or the recorder is IP-only, an IP turret camera on a PoE NVR would be the appropriate direction instead.
Fixed Lens Placement: The 2.8mm lens provides a wide field of view suited to open areas and broad scene capture, but it is not adjustable. If the installation point requires a narrower angle to cover a long corridor, gate entry, or distant target, consider a varifocal TVI turret with a motorised or manual zoom lens to allow the angle to be set at installation.

Ideal Use Cases
Analogue Site Resolution Upgrades
Sites running legacy coaxial cable can be upgraded to 8MP video using this TVI 4.0 camera without disturbing existing cable routes. The 4-in-1 output also eases the transition where older DVR hardware is being retained or gradually replaced.
Car Parks and Outdoor Hardstands
The 2.8mm lens and 60m Smart IR cover wide open areas effectively. The 130dB true WDR handles the contrast between vehicle headlights and surrounding darkness, maintaining usable image detail across the monitored zone.
Building Perimeter Monitoring
Mounted at eave or wall height, this turret camera covers wide building frontages and side approaches. The IP67 rating handles rain, dust, and variable outdoor conditions without requiring weatherproof housing or enclosures.
Driveways and Entry Points
At 3840 x 2160 resolution, this camera captures enough detail at a driveway entrance to allow review of vehicle and pedestrian activity from the recorded footage, particularly when positioned at a point where subjects pass relatively close to the camera.
Commercial Forecourts
Service stations, retail centres, and industrial forecourts with mixed lighting conditions benefit from the true WDR and ultra-low light sensor combination, maintaining consistent footage quality across daytime glare and low-light evening periods.
Choosing the Right Model
- Choose this model if: You are upgrading an existing analogue coaxial site to 8MP resolution and need a wide-angle outdoor turret that works with TVI, AHD, CVI, or CVBS DVRs without relaying cable infrastructure.
- Choose a different model if: The site uses a PoE NVR or IP-based recording system, as this camera transmits over coaxial only and is not compatible with IP network infrastructure. An IP turret camera with PoE would be the appropriate fit in that scenario.
- Choose a different model if: The installation position requires a narrower field of view to cover a specific target at longer distances. A TVI camera with a varifocal lens would allow the angle to be adjusted at commissioning to suit the specific viewing distance and coverage width required.
FAQs
- Does this camera work with my existing DVR?
The DS-2CE78U7T-IT3F outputs 4-in-1 switchable video in TVI, AHD, CVI, and CVBS formats. It is compatible with most DVRs that accept any of these formats. TVI 4.0 recorders are required to receive the full 8MP signal. Older DVRs may accept the camera but will cap the resolution at their maximum supported input, typically 5MP or lower.
- Can I use this camera on a PoE NVR?
No. This is a coaxial analogue camera using TVI 4.0 transmission. It requires a BNC coaxial connection to a compatible DVR and a separate 12VDC power supply. It does not have an Ethernet port and is not compatible with IP-based recording systems or PoE switches.
- What field of view does the 2.8mm lens provide?
A 2.8mm fixed lens on this sensor size produces a wide horizontal field of view, typically in the range of 100 to 110 degrees, making it well suited to covering broad outdoor scenes from a single mounting position. It is not adjustable after manufacture, so the angle is fixed at installation.
- How does the 60m Smart IR perform in practice?
The Smart IR system adjusts the infrared emitter intensity based on the distance of subjects in the frame. As someone walks toward the camera, the IR output reduces to prevent the image from washing out at close range. The EXIR emitter arrangement also distributes illumination more evenly across the frame compared to a single central IR LED.
- Is this camera suitable for outdoor use in Australian conditions?
Yes. The IP67 rating means it is fully protected against dust ingress and can withstand sustained water exposure, including rain and hosing. It is designed for permanent outdoor installation and operates on 12VDC, which is a stable supply format for outdoor coaxial CCTV systems. Security Wholesalers supplies this camera as part of the Hikvision TVI 4.0 range for the Australian market.
- What does true WDR at 130dB mean for image quality?
True WDR uses dual-exposure capture at the sensor level, combining a short and long exposure in each frame to retain detail in both bright and dark areas simultaneously. At 130dB, the DS-2CE78U7T-IT3F handles scenes with very high contrast, such as a shaded building entry with bright sunlight beyond it, without the bright zone blooming out and obscuring the darker foreground.
