Product Overview
For sites running existing coaxial infrastructure, the DS-2CE79U7T-AIT3ZF delivers a genuine 8MP 4K upgrade without replacing cabling. This metal-bodied turret camera is built for outdoor eave, soffit, and wall mounting at driveways, car parks, building perimeters, and commercial entry points where directional coverage and image detail both matter. Featuring a 2.7mm to 13.5mm motorised varifocal lens, the DS-2CE79U7T-AIT3ZF allows field of view adjustment from 108.1 degrees down to 45.6 degrees, with the lens refocusing automatically when zooming. Equipped with EXIR 2.0 infrared technology reaching 60m and a minimum illumination of 0.003 lux, it maintains usable image quality well into darkness. It also integrates 130dB true WDR to handle backlit entrances and high-contrast outdoor scenes. The 4-in-1 signal output, switchable between TVI, AHD, CVI, and CVBS, makes it compatible with a broad range of existing recorders. IP67-rated for dust and water ingress, it is well suited to harsh Australian outdoor conditions year-round.
Key Capabilities
8MP 4K Resolution on Coax
The 8.29MP CMOS sensor captures footage at 3840 x 2160, delivering four times the pixel count of 1080p. This level of detail is particularly useful at entry points and driveways where identifying faces, licence plates, or specific individuals at distance is required.
Motorised Varifocal Lens
The 2.7mm to 13.5mm motorised varifocal lens spans a field of view from 108.1 degrees to 45.6 degrees. The lens refocuses automatically when zoomed, removing the need for manual focus adjustment after installation, which is a time-saver on roof or eave mounts.
EXIR 2.0 with 60m IR Range
Hikvision EXIR 2.0 technology distributes infrared illumination more evenly across the scene, reducing the overexposed hotspot common with older IR designs. At 60m range, the camera covers long driveways, car park aisles, and building approaches without requiring supplemental lighting.
130dB True WDR
A 130dB wide dynamic range rating means the camera can simultaneously expose bright outdoor areas and darker indoor or shaded zones within the same frame. This is especially relevant at entrances where doors open to direct sunlight and create extreme contrast.
Ultra-Low Light Performance
With a minimum illumination of 0.003 lux in colour mode and 0 lux with IR active, the DS-2CE79U7T-AIT3ZF maintains detail in near-total darkness. This makes it practical for poorly lit outdoor areas where supplemental lighting is not installed.
4-in-1 Signal Output
The switchable TVI, AHD, CVI, and CVBS output means this camera can integrate with a wide range of existing hybrid and analogue recorders. Sites upgrading incrementally from older analogue systems can adopt this camera without replacing the entire recording setup immediately.
Best For
- Coaxial Infrastructure Upgrades: Sites with existing RG59 or RG6 coax runs can adopt 4K 8MP resolution without network rewiring, using the TVI4.0 signal mode on a compatible recorder.
- Outdoor Eave and Soffit Mounting: The turret form factor with 360-degree pan and 75-degree tilt adjustment makes positioning straightforward on angled eaves or flat soffits, without needing a separate mounting wedge in most cases.
- High-Contrast Entry Points: The 130dB true WDR makes this well suited to gate entries, roller door openings, and building facades where bright sky or direct sunlight creates heavy backlight behind subjects.
- Long Outdoor Approaches: The 60m EXIR 2.0 range and motorised zoom to 13.5mm combine to cover long driveways, car park aisles, and perimeter fence lines where a fixed-lens camera would require a closer mounting point.
Why Choose the DS-2CE79U7T-AIT3ZF
The DS-2CE79U7T-AIT3ZF occupies a specific niche: 8MP 4K image quality delivered over coaxial cable through the TVI4.0 standard, combined with a motorised varifocal lens that a basic fixed-lens coaxial camera cannot match. Where a standard analogue camera might top out at 1080p and offer no field of view flexibility post-installation, this model captures at 3840 x 2160 and allows lens adjustment from 108.1 degrees down to 45.6 degrees without a site revisit to swap optics. The EXIR 2.0 60m IR range extends coverage further than most turret cameras in this form factor, and the 130dB true WDR handles backlit scenes that would wash out a lesser sensor. The IP67 metal housing is rated for continuous outdoor exposure including rain and dust ingress. Available at Security Wholesalers, the DS-2CE79U7T-AIT3ZF suits integrators and end users who want a meaningful resolution upgrade on an existing coaxial system.
Buyer Decision Tips
Recorder Compatibility: The DS-2CE79U7T-AIT3ZF transmits 8MP over TVI4.0 and requires a recorder with confirmed TVI4.0 support at 8MP to take full advantage of the sensor resolution. Recorders that only support TVI 1.0 or 2.0 will typically fall back to lower resolutions. Check your DVR or XVR specification sheet for TVI4.0 8MP channel support before purchasing.
Frame Rate at 8MP: At full 8MP resolution, the DS-2CE79U7T-AIT3ZF records at 12.5fps (PAL) or 15fps (NTSC). If smooth motion recording is a priority for high-traffic areas, note that higher frame rates of 25fps or 30fps are only available by dropping to 4MP or 1080p mode. This is a hardware constraint of the TVI4.0 standard at 8MP, not specific to this model.

Ideal Use Cases
Commercial Driveways
The 60m EXIR 2.0 IR range and motorised zoom to 13.5mm allow this turret camera to cover long vehicle approaches from a single mounting point at the building eave or gate post, capturing detail at range without a second camera position.
Car Park Monitoring
The 8MP resolution provides enough pixel density across a wide parking area that individual bays can be reviewed in post-incident footage. The wide-angle end of the varifocal lens at 108.1 degrees covers a broad sweep from a column or eave mount.
Building Entry and Exit Points
The 130dB true WDR manages the harsh backlight created when entry doors open to direct sunlight, ensuring subjects entering or exiting are not silhouetted against a washed-out background.
Coaxial System Upgrades
Sites with existing RG59 or RG6 coaxial runs can adopt 4K resolution using TVI4.0 without replacing cabling. The 4-in-1 output also maintains backward compatibility with older hybrid recorders running AHD, CVI, or CVBS inputs.
Industrial Perimeters and Yards
The IP67-rated metal housing tolerates outdoor dust, rain, and temperature extremes from -40 to 60 degrees C, making the DS-2CE79U7T-AIT3ZF appropriate for exposed industrial sites where plastic-bodied cameras deteriorate over time.
Choosing the Right Model
- Choose this model if: You have an existing coaxial infrastructure and want to upgrade to 8MP 4K resolution with a motorised varifocal lens and 60m IR coverage, without replacing cabling or migrating to an IP network.
- Choose a different model if: Your system runs on a network switch and you want PoE-powered IP cameras, which provide greater frame rate flexibility at high resolution and support remote configuration over the network without separate power wiring.
- Choose a different model if: You need full 25fps or 30fps frame rates at 8MP. The TVI4.0 standard limits 8MP recording to 12.5fps or 15fps on this camera. Dropping to 4MP or 1080p mode is required for smoother motion capture at higher frame rates.
FAQs
- What type of recorder do I need to use the DS-2CE79U7T-AIT3ZF at 8MP?
You need a DVR or XVR with confirmed TVI4.0 support at 8MP resolution. Not all TVI-compatible recorders support TVI4.0 at 8MP. Check your recorder’s channel specification for TVI4.0 8MP compatibility before purchase. Connecting to an older TVI recorder will typically result in a lower-resolution fallback, not an error.
- What frame rate does this camera record at in 8MP mode?
In 8MP mode using TVI4.0, the DS-2CE79U7T-AIT3ZF records at 12.5fps on PAL systems and 15fps on NTSC systems. If your application requires 25fps or 30fps, you would need to switch the camera to 4MP or 1080p mode, which are both supported output options on this camera.
- Can I install this camera on an existing coaxial cable run?
Yes. The DS-2CE79U7T-AIT3ZF transmits over standard coaxial cable using the TVI4.0 signal. Existing RG59 or RG6 runs can be retained. The practical cable run length for TVI4.0 at 8MP will depend on cable quality and the recorder being used. Refer to your recorder manufacturer’s guidance for maximum cable distances at TVI4.0.
- How does the motorised varifocal lens work on this turret camera?
The 2.7mm to 13.5mm motorised varifocal lens is adjusted electronically, typically via the OSD menu through the recorder or a compatible controller. When the focal length is changed, the lens automatically refocuses, eliminating the need to access the camera physically to manually turn a focus ring after zooming in or out.
- Is the DS-2CE79U7T-AIT3ZF suitable for permanent outdoor installation?
Yes. The camera carries an IP67 rating, confirming it is protected against dust ingress and sustained water exposure including rain. The operating temperature range of -40 to 60 degrees C covers outdoor conditions across all Australian climates. The metal housing provides additional durability over plastic alternatives for long-term outdoor mounting.
- What does 4-in-1 signal output mean on this camera?
4-in-1 refers to the ability to switch the camera’s video signal output between TVI, AHD, CVI, and CVBS formats. This is configured via the OSD menu. It allows the same physical camera to be used with different recorder brands and types, which is useful when integrating with existing hybrid DVR systems that may use a different analogue standard.
