Dahua IPC-HFW2849T-ZAS-IL-27135-B IP camera 8 MP, 2.7–13.5 mm, IR 60 m

A resolution of 3840 × 2160 is 4K, four times the pixels of a Full HD camera. When you zoom into a recording, faces, clothing and vehicles stay sharper. The 1/2.7″ CMOS sensor with starlight technology delivers a better picture at dusk, and 120 dB WDR balances bright and dark areas, for example when the camera looks out from a gateway onto the street.

The focal length adjusts between 2.7 and 13.5 mm. At the wide end the horizontal field of view is 114°, enough for a whole yard or car park; at the narrow end it is 32°, bringing a distant gate or driveway closer. According to the manufacturer, the detection distance reaches 280 m, observation 112 m, recognition 56 m and identification 28 m. One camera model can therefore handle very different jobs.

At night the camera normally runs on infrared and records in black and white. When a target enters the monitored area, the warm light switches on and the event is captured in full colour. Once the target leaves, the warm light goes off and IR takes over again. That means less light pollution for the neighbours while key moments are kept in colour. Both lights reach up to 60 m.

As a WizSense 2 series camera, it uses deep-learning perimeter protection: intrusion and tripwire detection classify targets as people or vehicles. SMD Plus filters out motion that does not matter, such as branches or shadows. The camera also reports memory card errors, network disconnection, IP conflicts and unauthorised login attempts. Four privacy zones can be masked in the frame.

The camera runs on PoE (IEEE 802.3af) or a 12 V adapter, and its wide input voltage tolerance suits sites with an unstable supply. It records to a microSD card of up to 256 GB, to network storage (NAS) or to a recorder. You manage it in a web browser, with Smart PSS and DSS, or in the DMSS app on Android and iOS. It measures 238.5 × 90.7 × 90.7 mm, weighs 760 g and mounts on a ceiling or wall.

Private houses, business yards, car parks and storage areas that need 4K detail and the option to fine-tune the field of view on site. The black housing blends into a dark facade. It suits installers looking for a wired PoE camera with smart alarms and colour night recording.
