Dahua HDBW2431R-ZS-S2 security camera outdoor ideal for professional video surveillance, with IR night vision LED and a high resolution of 4 megapixel

With a bright Starlight sensor and motorized focus / zoom lens, the Dahua IP dome camera convinces in all professional video surveillance systems, with high-quality processing, a brilliant video image and many setting options for an optimal result.

The following are available in the accessories area: Junction box for the vandal-proof housing of connection cables PFA137. You need the pole mount bracket PFA152-E for pole mounting. The PFB203W wall bracket is suitable for hanging mounting on walls.

Exact coverage of the surveillance area

With the high-quality focus / zoom lens, which can be precisely adjusted to the area to be monitored using motor control and automatic focusing, you will achieve an optimal result.

The angle of view is 27° (13.5mm) with telephoto and 104° (2.7mm) with zoomed out lens.

Good night vision even in total darkness

High-performance LEDs for infrared lighting ensure homogeneous illumination with a range of up to 40 meters. So no additional lighting fixtures are required. With the Smart IR technology, objects that are too close to the camera are automatically dimmed. This prevents these objects from being outshone by the infrared LEDs.

Since the IR spectrum is above the color spectrum, the videos are shown in black and white at night. If you still want to display in color at night, white light spotlights are necessary.

All-round protection against rain, dust and vandalism

With the IP67 classification, the camera is very well protected even in extreme weather conditions. With the IK10 level of impact resistance, it also offers extreme protection against vandalism.

Video analysis built in

Dahua's VCA algorithm provides alerting when crossing lines or entering predetermined areas. This reduces the number of false alarms and warns of danger or unauthorized access. The surveillance camera also has motion detection on the outside. The ranges and sensitivity of the trip can be easily configured. An alarm is automatically triggered when motion is detected in these areas.This also happens when the camera is covered or rotated.

Local recording

In addition to the usual recording option via connected NVR recorders, the Dahua HDBW2431R-ZS-S2 also offers a built-in SD card slot that accepts micro SD cards up to a capacity of 256GB.

Either video sequences or alarm images can be recorded here. In the case of continuous recording on an SD card, we ask you to consider that the SD cards are generally not suitable for permanent recording. Here you should fall back on the proven technology of NVR recorders.

WDR technology

If there are extreme differences in brightness in the image, WDR technology helps with the compensation, 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 the 1-cable solution. Here the supply voltage of the dome camera is led together with the video data via 1 network cable. This eliminates the need to install a socket near the camera. Especially in the outside area, this leads to considerable additional effort. A POE switch is required to use the POE.

Protect privacy

The Dahua IP camera HDBW2431 offers up to 4 areas that can be set independently in size and areas. This hides certain zones in the image that are made unrecognizable. This is important in the event that the neighboring property or house entrances should not be monitored by neighbors.

Areas of application of the surveillance camera outside

House surveillance outdoors, surveillance of courtyard areas and parking lots, entrance surveillance of company buildings and gate entrances (loading zones). As an indoor camera, the Dahua IP dome camera can monitor the foyers, reception and warehouse.
