The Dahua HDBW2431R-ZS-S2 outdoor security camera is ideal for professional video surveillance, equipped with an infrared LED and high 4 megapixel resolution.

Equipped with a bright Starlight sensor and motorized varifocal lens, the Dahua IP dome impresses all professional video surveillance systems with its high quality processing, excellent video and many setting options for optimum results.

The following options are available in the accessories area: Junction box for the vandal-resistant cable housing PFA137. A pole mount bracket PFA152-E is required for pole mounting. The PFB203W wall mount is suitable for wall mounting.


Exact coverage of the surveillance area

With a high-quality zoom lens that can be precisely adjusted to the area to be monitored by motor control and autofocusing, you will achieve the optimum result.

The viewing angle is 27° (13.5 mm) for a telephoto lens and 104° (2.7 mm) for a reduced magnification lens.


Good night vision, even in total darkness

High-performance infrared LEDs provide homogeneous illumination with a range of up to 40 metres. No additional lighting fixtures are therefore required. Thanks to Smart IR technology, objects that are too close to the camera are automatically dimmed. This prevents the infrared LEDs from overexposing these objects.

As the infrared spectrum is above the colour spectrum, films are displayed in black and white at night. If the image is to continue to be displayed in colour at night, it is necessary to use spotlights with white light.


Versatile protection against rain, dust and vandalism

Thanks to the IP67 protection class, the camera is very well protected even in extreme weather conditions. Thanks to its impact resistance at IK10 level, it also offers extreme protection against vandalism.


Built-in video analysis

The Dahua VCA algorithm provides an alarm when crossing a line or entering predefined areas. This reduces false alarms and warnings of danger or unauthorised access. The surveillance camera also has an outdoor motion detection function. The detection range and sensitivity can be easily configured. An alarm is triggered automatically when motion is detected in these areas. This also happens when the camera is covered or rotated.


Local recording

The Dahua HDBW2431R-ZS-S2 offers, in addition to the usual recording option via connected NVRs, a built-in SD card slot that accepts micro SD cards up to 256 GB.

Video sequences or alarm images can be recorded here. In the case of continuous recording on an SD card, please note that SD cards are generally not suitable for continuous recording. In this case, you must rely on proven NVR technology.


WDR technology

When there are extreme differences in image brightness, WDR technology helps to compensate, so that objects in front of extremely bright light sources can still be identified.


POE power supply for the camera

The Dahua outdoor surveillance camera has a 1-cable solution. Here the power supply voltage of the dome camera is supplied together with the video data via 1 network cable. This eliminates the need to install a socket near the camera. Especially in the outdoor area, this leads to considerable additional effort. A POE switch is required to use POE.


Privacy protection

The Dahua IP camera HDBW2431 offers up to 4 areas that can be set independently of each other in terms of size and area. This hides certain areas in the image that are unrecognizable. This is important if the entrances to an adjacent facility or house should not be monitored by neighbours.


Areas of application for an outdoor surveillance camera

Outdoor house supervision, supervision of courtyard and parking areas, supervision of entrances to company buildings and gateways (loading zones). As an indoor camera, the Dahua IP dome camera can monitor the foyer, reception and warehouse.
