Description

25× zoom that brings distant detail close

The lens spans 5.4–135 mm, which is a 25× optical zoom. At the wide end the horizontal field of view is 61.6°, at full zoom just 3.6°, so the camera can move quickly from an overview to the details of a car or person far away. A 16× digital zoom comes on top. Autofocus keeps the picture sharp while zooming, and electronic stabilisation reduces shake.

Auto-tracking 3.0 follows the target by itself

When perimeter protection detects a person or vehicle entering a zone, the camera can lock onto the target automatically and follow it, zooming in as needed. The operator does not have to steer the camera manually. It also supports face detection and SMD 4.0 smart motion detection, which cuts down false alarms. For patrols you can set up presets, 5 patterns, 5 scans and 8 tours.

Starlight and IR up to 150 metres

The 1/1.8″ STARVIS CMOS sensor and starlight technology produce a usable picture even in very weak light, with a minimum illumination of 0.0001 lux. In total darkness the IR reaches up to 150 metres, which matches the long zoom of a PTZ camera well. A full-colour illuminator allows colour recording at night when you need to tell the colour of clothing or vehicles.

Active warning with red and blue lights

The PV designation stands for active deterrence: the camera has red and blue warning lights that let an intruder know they have been seen. Combined with auto-tracking, this means the camera does not just record but reacts on its own. One alarm input and one output let you tie the camera to sensors, a siren or gate automation.

Built for harsh conditions

The IP66 housing is dust-tight and withstands powerful water jets, and the camera operates from −40 to 70 °C. Power comes over PoE+ (IEEE 802.3at) or from a DC adapter, with 13 W typical and 23 W maximum consumption. The camera weighs 4.6 kg, measures 202 × 202 × 325.3 mm and mounts on a ceiling or wall. Up to 24 privacy zones can be masked in the frame.

Who this PTZ IP camera is for

Large car parks, logistics and industrial sites, ports, construction sites and public spaces where one camera has to cover a wide area and zoom far when needed. Security services and integrators that need automatic target tracking and active warnings. It works on its own or as part of a larger Dahua system.

Questions & answers

Does the camera run on PoE?

Yes, it supports PoE+ to IEEE 802.3at, with a maximum draw of 23 W. The switch port therefore needs to support PoE+. A DC adapter is the alternative.

How far can the camera see at night?

The IR reaches up to 150 metres, and there is also a full-colour illuminator for colour night footage.

Does the camera track moving targets by itself?

Yes, Auto-tracking 3.0 locks onto a person or vehicle and follows it automatically.

Can the camera be installed outdoors?

Yes, the housing is rated IP66, and the operating range is −40 to 70 °C.

Does the camera record audio?

The manufacturer does not specify a microphone or audio input.
