HiLook IPC-T249HA-LU(4mm) is a 4MP Smart Hybrid Light fixed turret IP camera with a 4mm lens, built-in microphone, ColorVu low-light colour imaging, Motion Detection 2.0 and PoE. With an F1.0 super aperture and Super Confocal technology, it delivers vivid colour footage day and night and classifies detected movement as human or vehicle to reduce false alerts.

HiLook IPC-T249HA-LU(4mm) 4MP Smart Hybrid Light Fixed Turret IP Camera with Built-In Microphone and ColorVu

The HiLook IPC-T249HA-LU(4mm) is a 4MP PoE turret network camera from HiLook by Hikvision, featuring a 4mm fixed lens with an F1.0 super aperture and Smart Hybrid Light technology combining infrared and white light illumination. It delivers a maximum resolution of 2560 × 1440 and maintains vivid colour imaging in extremely low-light conditions down to 0.001 Lux, while Motion Detection 2.0 provides intelligent human and vehicle classification to reduce unnecessary alarm notifications.

The 4mm lens offers a narrower field of view than the 2.8mm variant — 80° horizontal versus 96° — making it better suited to monitoring longer corridors, driveways, access roads or approaches where more distance coverage is needed from a fixed mounting point. All other specifications are identical to the IPC-T249HA-LU(2.8mm).

4MP Resolution with F1.0 Super Aperture

The camera uses a 1/3" Progressive Scan CMOS sensor delivering 2560 × 1440 resolution. The 4mm fixed lens with F1.0 aperture and M12 mount provides a horizontal FOV of 80°, vertical FOV of 43° and diagonal FOV of 93°. The large F1.0 aperture allows significantly more light to reach the sensor compared to standard F2.0 lenses, contributing to superior low-light colour performance. Super Confocal technology ensures the camera stays sharply focused when switching between infrared and visible light modes.

Smart Hybrid Light — Three Lighting Modes

The camera combines IR and white light illumination with three selectable modes:

• Smart Mode (default) — infrared illumination is used by default; white light activates automatically when a human or vehicle is detected, switching to vivid colour at the moment of an event
• 24/7 Colour Mode — white light remains active continuously for full-colour imaging at all times
• IR Mode — infrared only, producing black and white imagery in low light

Supplement light range is up to 30 metres in both IR and white light modes. Minimum colour illumination is 0.001 Lux with the F1.0 aperture and AGC enabled; the camera captures in complete darkness (0 Lux) with white or IR light active.

Motion Detection 2.0 — Human and Vehicle Classification

Motion Detection 2.0 uses deep learning to classify detected movement as a human or a vehicle. Alerts and recording triggers respond only to these target types, filtering out environmental false alarms such as animals, foliage, shadows and lighting changes. Footage can be searched quickly by event type via connected NVR or management software.

Built-In Microphone for Audio Monitoring

A built-in microphone captures ambient audio alongside video. Audio is transmitted over the network connection alongside the video stream and can be recorded by a compatible NVR. Audio compression options include G.711, G.722.1, G.726, MP2L2 and AAC-LC at 16–160 Kbps.

On-Board Storage

A built-in microSD/SDHC/SDXC card slot supports cards up to 256GB, allowing local edge recording independent of an NVR. This provides a backup recording layer and enables standalone operation for simpler installations.

H.265+ Compression and PoE

The camera supports H.265+/H.265/H.264+/H.264 main stream compression, with H.265+ reducing storage and bandwidth requirements by up to 75% compared to standard H.264. Power is supplied via PoE (IEEE 802.3af) over a single Ethernet cable, eliminating the need for a separate power supply.

IP67 Weatherproof Rating

The camera is rated IP67 for full dust ingress protection and resistance to water immersion, making it suitable for permanent outdoor installation in all UK weather conditions. Operating temperature range is −30°C to +60°C.

FREQUENTLY ASKED QUESTIONS (FAQs)

What is the difference between the IPC-T249HA-LU(4mm) and the IPC-T249HA-LU(2.8mm)?

The only difference is the lens. The 4mm version provides a narrower 80° horizontal FOV and a longer DORI detection range of 77m, making it better for monitoring longer distances such as driveways, approaches and corridors. The 2.8mm provides a wider 96° FOV and is better for covering broader areas at closer range. All other specs — sensor, resolution, aperture, Smart Hybrid Light, Motion Detection 2.0, microphone, PoE and IP67 — are identical.

What is Smart Hybrid Light?

Smart Hybrid Light combines infrared and white light illuminators. In Smart Mode, the camera uses IR by default and automatically activates white light when a human or vehicle is detected, capturing full colour detail at the moment of an event. Continuous colour (white light always on) and IR-only modes are also selectable.

Does it support night vision in colour?

Yes. The F1.0 aperture and ColorVu technology enable colour imaging down to 0.001 Lux. With white light active, the camera captures in complete darkness (0 Lux).

Is it suitable for outdoor installation?

Yes. The camera carries an IP67 protection rating and operates from −30°C to +60°C, suitable for permanent outdoor use in UK conditions.

Does it need a separate power supply?

No. The camera is powered via PoE (IEEE 802.3af) over the same Ethernet cable used for data — no separate power supply or cabling is required.

Does it support local recording without an NVR?

Yes. A microSD/SDXC card up to 256GB can be inserted for local edge recording.

What smart detection does it support?

Motion Detection 2.0 classifies movement as human or vehicle, filtering out environmental false alarms. Alerts trigger only for these target types.
