The 4MP perimeter reach specialist
The Hikvision DS-2CD2T46G2-4I with the 6mm lens is what you install when the boundary wall is too long for a 4mm lens to resolve identification-grade detail at the far end. 4MP resolution combined with a tight 6mm focal length delivers usable face and number-plate detail at 18 to 30 metres, in the T-series body with full 60-metre IR backup for total-darkness coverage.
This is the dedicated reach camera. It is not the right call for general-purpose front yards, porches, or close-quarters positions. Where it earns its keep is on long perimeter walls, smallholding access roads, and industrial yards where the camera needs to cover a long, narrow zone rather than a wide scene.
What this camera is actually good at
- 4MP resolution. Sharp identification-grade detail at the centre of the frame.
- Tight 6mm lens. Roughly 56° horizontal field of view. Genuinely focused on reach rather than scene capture.
- AcuSense onboard AI. Human and vehicle classification, filtering out animals, wind, and environmental noise.
- T-series long-range IR. Up to 60 metres of supplementary illumination, well-matched to the 6mm lens range.
- 120 dB WDR. Bright-into-dark transitions handled cleanly.
- IP67 weather-sealed. Built for exposed perimeter mounting.
- H.265+ compression. Doubles your effective recording capacity.
Where this camera belongs on your property
- Long boundary walls (25+ metres) watching a defined section of perimeter at distance
- Smallholding access roads watching the approach to the gate from a higher mounted position
- Industrial site perimeters covering a section of fence or yard at usable identification detail
- Estate boundary positions watching for activity along long sections of wall
- Sports field, school ground, and parking area perimeters covering long defined zones
If you want a wider view or active deterrent
- The DS-2CD2T46G2H-4I 2.8mm is the wide-angle alternative for shorter scenes.
- The DS-2CD2T46G2H-4I 4mm is the standard-focal alternative for medium-distance positions.
- The DS-2CD2T46G2-ISU/SL drops to a wider lens but adds active strobe and siren.
- The DS-2CD2646G2HT-IZS 2.8 to 12mm motorised zoom gives you flexibility between wide and tight in one unit.
If you want to compare at this level
- The DS-2CD2086G2H-I 8MP ColorVu trades reach for resolution and full-colour night vision. The right call at the front gate where identification quality matters most.
- The DS-2CD2T46G2H-2I 4mm is the compact-housing 4MP option with a wider lens.
Pairs cleanly with the DS-7616NXI-K2 16-channel NVR. Our home CCTV installation guide covers system design across property types, including how reach cameras work alongside wide-angle units.
Reach cameras need careful aiming
A 6mm lens with the camera misaligned by a few degrees can put your identification zone in the wrong place entirely. We do precision alignment, focus-locking, and detection-zone configuration as part of every install across Pretoria East, Centurion, Midrand, and Johannesburg.
