The HiLook THC-T259-MS(2.8mm) is a 3K/5MP ColorVu Turbo HD turret camera with 24/7 full-colour imaging, built-in microphone and speaker, and IP66 weatherproofing. This is the Grey housing finish, a UK-limited official HiLook variant confirmed on hikvision.com. It works over a single coax cable, switching automatically between TVI/AHD/CVI/CVBS signal types.
HiLook THC-T259-MS(2.8mm) 3K ColorVu Audio 3K ColorVu Audio Turret Network Camera
The HiLook THC-T259-MS uses a 3K CMOS sensor delivering 2960 × 1665 resolution. ColorVu technology, enabled by a large F1.0 aperture and supplemental white light, maintains full-colour imaging 24 hours a day rather than switching to black & white at night, with minimum illumination rated at 0.001 Lux (AGC on).
The 2.8mm fixed lens gives a horizontal field of view of 113°, vertical FOV of 62° and diagonal FOV of 137°, with a white light range of up to 40m for bright night-time colour imaging. Built-in audio (microphone and speaker, transmitted over coax) and an IP66 weatherproof rating make it suited to outdoor installation on hybrid Turbo HD systems.
3K/5MP ColorVu Imaging
Resolution is 2960 × 1665, with 3K recording at 20fps (TVI) and 4MP/1080p recording available at up to 30fps depending on the connected DVR. ColorVu keeps colour detail visible around the clock rather than reverting to IR black & white at night.
Switchable Signal Support (TVI/AHD/CVI/CVBS)
A single coaxial port supports four switchable analog signal types — TVI, AHD, CVI and CVBS — allowing the camera to work with a wide range of existing analog DVRs without additional converters.
Built-In Audio Over Coax
Audio is transmitted over the same coaxial cable as video, avoiding the need for separate audio wiring. This supports basic two-way communication and audio recording alongside footage where the connected DVR supports it.
IP66 Weatherproofing
Rated IP66 against dust and powerful water jets, suitable for permanent outdoor installation.
