The 4MP boundary-wall workhorse
There is a moment every Pretoria homeowner knows. The dogs go off at the back fence at 2am, your phone is silent, and you are standing in the dark trying to decide whether to get out of bed. Was that someone climbing the wall, or was it the cat?
The Hikvision DS-2CD2T46G2H-4I is the camera we install on driveways, boundary walls, and perimeter views to take that decision out of your hands. It is a 4MP IP bullet camera with onboard AcuSense-style AI. The chip inside the camera looks at every moving thing in its view, decides whether it is a person, a vehicle, or just the wind, and only sends an alert to your phone when something genuinely matters.
That sounds like a small thing. In practice it is the difference between a CCTV system you trust and one you mute within a fortnight, which (as we have written about elsewhere) is the single most common reason CCTV fails to protect the people who pay for it.
What this camera is actually good at
- 4MP resolution. Sharp enough that when you scroll back through the footage three days later, you can still read a number plate, see the logo on a hoodie, or tell SAPS the colour of the shoes.
- DarkFighter low-light performance. This is the technology that means you do not need to flood your driveway with halogen lights at night. The camera pulls usable detail out of streetlight, gate-light, even moonlight on a clear evening.
- 120 dB true WDR. When a car turns into your driveway with its headlights pointed at the camera, you do not lose the driver’s face to glare. The camera balances bright and dark the way your eyes do.
- AcuSense human and vehicle classification. Filters out the dogs, cats, bats, wind in the trees, and the moths fluttering around the IR LEDs. Only humans and vehicles trigger the alert on your phone.
- H.265+ video compression. Your hard drive holds roughly twice as much footage. Useful when you want to scroll back to last Tuesday morning to check what time the gardener actually arrived.
- IP67 weather-sealed housing. Built for Highveld hailstorms, summer thunderstorms, and dust. We have units installed in 2014 still running today.
- 60-metre IR illumination range for total-darkness coverage on long driveways and perimeter walls.
Lens options: 2.8mm or 4mm
The DS-2CD2T46G2H-4I comes in two lens variants. Choose based on how far the camera is from what you actually want to identify:
- The 2.8mm wide-angle version covers a 102° horizontal field of view. The right call for driveways under 15 metres, front yards, and back gardens where one camera covers the whole scene.
- The 4mm tighter version trades peripheral coverage for usable detail at distance. The right call for long boundary walls, driveways over 15 metres, and any position where the camera is more than 10 metres from the people you want to identify.
Many properties end up running both: the 2.8mm at the front of the house, the 4mm watching long perimeter walls.
Where this camera belongs on your property
- Long boundary walls alongside an alley, an open field, or another property’s vacant stand
- Driveways from front gate to garage
- The back of the house watching the patio, pool area, and back garden
- Cluster home outer walls where the body corporate allows external cameras
If you want a bit more, or a bit different
- The DS-2CD2086G2H-I ColorVu 8MP is the step up when you want full-colour night footage and twice the pixels. The right call for the front gate of a larger home.
- The DS-2CD2T46G2-ISU/SL takes the same 4MP bullet body and adds a built-in strobe and siren, so the camera does not just record the trespasser, it actively tells them to leave.
- The DS-2CD2646G2HT-IZS 2.8 to 12mm gives you the same AI on a 4 to 12mm motorised zoom, useful when one camera needs to cover a long view and zoom in close.
- For a smaller, lower-profile mount where the bigger T46 housing is overkill, the DS-2CD2T46G2H-2I is the compact sibling product.
For 6+ camera homes, this camera pairs natively with the DS-7616NXI-K2 16-channel NVR. A single ethernet cable from the recorder to the camera carries both data and power. For complete system design by property type, our home CCTV installation guide walks through camera selection.
Getting it to deliver what it promises
Hikvision AI features only deliver the false-alarm reduction the brochure promises when the detection zones, sensitivity thresholds, and notification rules are properly configured for the specific property. A factory-default install will still fire ten alerts a night from a neighbour’s washing line.
If you would like us to install and configure it for you, we cover Pretoria East, Centurion, Midrand, and Johannesburg. Every camera fully tuned and live-tested before we leave.
Full 3-year Hikvision South Africa warranty through authorised distribution. Pricing on the CCTV installation prices page.
