HiLook THC-T257-LTS 3K Smart Hybrid Light Turret Camera 2.8mm 105° with Two-Way Audio

Overview

The HiLook THC-T257-LTS(2.8mm) is a 3K analogue turret camera built around two ideas that matter on real sites: see it in colour and talk to it. At 2960 × 1665 it resolves noticeably more detail than the 2 MP THC-T227-LTS it sits above, while running down the same coax you already have.

Smart HybridSmart Hybrid Light Light pairs 40 m Smart IR with a white-light LED reaching up to 40 m. Left alone, the camera records mono at night on IR and switches to full colour when something happens. Paired with an AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide DVR, that switch can be driven by a human or vehicle classification rather than any movement — so the white light comes on for a person in the yard, not for a fox or a branch in the wind. On a residential or small-commercial site that is the difference between a deterrent and a nuisance.

Audio is genuinely two-way. A built-in microphone picks up to about 5 m and a 2 W speaker projects roughly the same, both carried over the existing coaxial cable via audio over coax (AoCWhat is Hikvision AOC) — no second cable run. Echo cancellation, AI noise reduction and automatic gain control are handled in the camera, so a live challenge over the speaker is intelligible rather than a howl of feedback.

It is comparable to the Hikvision DS-2CE72KF0T-LTS — the same housing, two-way audio and 40 m light range — while the Hikvision model adds an F1.0 ColorVuHikvision AcuSense vs ColorVu: UK Installer Guide for 2026 lens (0.001 lux) and 3D DNR; this HiLook uses an F2.0 lens (0.01 lux) with 2D DNR, at HiLook trade pricing.
