DS-2CD2T46G2H-2I

The Hikvision DS-2CD2T46G2H-2I 4mm is the compact 4MP AcuSense bullet with a tighter lens, for positions where you want detail at distance without the bigger T46 housing. Smaller body, same AI, same low-light performance, narrower field of view for reaching across a yard or down a driveway.

The compact 4MP bullet with reach

The Hikvision DS-2CD2T46G2H-2I with the 4mm lens is what you install when you want detail at distance but the bigger T46 body is more camera than the position calls for. The smaller housing slips under eaves, sits cleanly above doorways, and works in cluster home positions where a chunky perimeter camera would look out of place. The 4mm lens trades some peripheral coverage for usable face and number-plate detail at 8 to 15 metres, which is exactly the right range for most domestic positions where you need to recognise someone rather than just spot that they exist.

What this camera is actually good at

4MP resolution with a tighter 4mm lens. Roughly an 84° horizontal field of view. Less of the scene captured, but anyone in the frame is captured at properly usable detail.
AcuSense onboard AI. The chip classifies humans and vehicles separately from background activity. Cats, dogs, wind, headlights bouncing off the gate: silenced. A person stepping onto the property: alert on your phone within seconds.
DarkFighter low-light technology. Pulls usable detail out of light levels far below what standard cameras handle. Around 30 metres of IR illumination for total darkness.
120 dB WDR. Headlights, porch lights, and harsh sun get balanced rather than blown out. The driver’s face stays visible when the car turns into the driveway.
IP67 weather-sealed housing. Sized for tighter positions but built to the same Hikvision standard as the bigger bullets. Hail, rain, dust, summer heat.
H.265+ compression. Roughly doubles your effective recording capacity versus older H.264 systems.

Where this camera belongs on your property

Watching a back yard or pool area from a corner-of-house mount, where you want to identify people rather than survey the scene
Side passages longer than a few metres, where a wide lens would render the far end as smudgy pixels
Driveway side-mounts on cluster homes and townhouses, where the body corporate prefers smaller external cameras
Cottage and outbuilding entrances where you want to read faces clearly at the door
Carports watching the parking bay and the entry from a single mount

For wider scenes and shorter distances (front yards, patios, back yards in compact suburban homes) the 2.8mm version of this same camera is the right pairing. For longer perimeter walls and driveways over 15 metres, the bigger-bodied DS-2CD2T46G2H-4I 4mm with its longer IR reach is the more capable choice.

If you want to step up

The DS-2CD2086G2H-I ColorVu 8MP doubles the pixels and gives you full-colour footage at night. Worth it for the front-of-house position on larger homes.
The DS-2CD2646G2HT-IZS 2.8 to 12mm swaps the fixed lens for a motorised zoom. Useful when one camera position needs to flex between a wide situational view and a tight zoom on a specific area.
The DS-2CD2T46G2-ISU/SL adds a built-in strobe and siren for active deterrence. The camera does not just record the trespasser, it tells them to leave.

For multi-camera setups, this camera pairs natively with the DS-7616NXI-K2 16-channel NVR over a single ethernet cable. For thinking about how many cameras your property actually needs and where they should go, our home CCTV installation guide walks through it by property type.

Configuration is what makes the AI work

The detection zones, sensitivity thresholds, and notification rules need to be tuned for your specific property. A factory-default setup will still fire alerts at the neighbour’s washing line in a strong wind. We do that configuration work on every install across Pretoria East, Centurion, Midrand, and Johannesburg, with a live test before we leave.
