Dahua SD49425GB-HNR 4MP 25x Starlight IR Network PTZ Camera
Product Description
This camera is part of the WizMind series, so it is designed to recognize human faces and count people, making it possible to act quickly and precisely on what is important to you. At the same time, it offers a much more advanced AI search to locate the target much easier.
The SD49425GB-HNR surveillance camera benefits from a resolution of up to 4 MP 2K, thus capturing clear images.
The quality of the images has been significantly improved thanks to the Starlight technology, designed to provide a bright image, rich in details. In this way, the images can be displayed in color even under difficult lighting conditions.
The device also has IR, which is activated when there is not enough light in the frame. The images can be captured from a distance of up to 100 meters and are played back in black and white.
The SD49425GB-HNR camera has a varifocal lens with a focal length of 5mm 125mm, which enables optical zoom up to 25x. To be precise: with the SpeedDome SD49425GB-HNR the image can be magnified 25 times without loss of quality.
Featuring a high-performance 1/2.8” CMOS sensor, the device uses a large aperture lens (F1.6-F3.6) to absorb a greater amount of light.
Another important feature is represented by the WDR function (Wide Dynamic Range). This equalizes the brightness of the image, to create a comprehensible level, both in brightly lit areas and in areas with lower brightness.
Equipped with intelligent algorithms, the camera features face detection, capturing and selecting the image that shows the clearest details. In addition, Dahua Smart Motion Detection technology enables the classification of targets that trigger motion detection, reducing false alarms caused by other objects or animals.
Another intelligent feature is represented by Perimeter Protection, which allows you to demarcate the area intended for surveillance. Motion detection will therefore only occur in that area.
In addition, the captured images can be viewed wherever you are, using the DMSS mobile application. In this way, you can access information about the monitored area and make various settings directly from the application. In case of an unforeseen change, you will be warned by means of push notifications, which are sent directly to the mobile application.
The camera can be powered classically at 12VDC or via a PoE network cable, allowing power supply and data transfer at the same time.
At the same time, the SD49425GB-HNR surveillance camera has a microSD card slot, with a capacity of up to 512 GB.
In addition, the SD49425GB-HNR camera has increased weather resistance, as it is equipped with the IP66 protection index. Thanks to the TVS 6000V index, the device is also protected against overvoltage or lightning.
