A high-performing sensor and special algorithms work together to capture images in low-light and no-light environments. Starlight technology generates clear images in near-complete darkness. Intelligent Detection & Perimeter Protection – This allows you to draw a digital perimeter on the NVR to define a safe boundary perimeter before triggering a push notification alert to your phone. Through advanced video algorithms, Dahua's Intelligent Video Surveillance (IVS) technology supports smart functions such as tripwire and intrusion detection. As the old generation, 46 are at the bottom.Dahua 8MP 4K Starlight IP Turret Motorised Optical Zoom Security Camera.If the environment has some light, number plate is very hard to be recognized by 5442-led, due to the strong reflection, but It is worth noting that 5542-led do make other objects (like human face or clothes) clearer. Therefore, if you want get the color image in a very dark condition, 5442-led fullcolor camera is a only choice. 5442-LED and 5442 are the top two night vision cameras, while 5442-LED is better in a complete dark environment owing to its extra LED lamp.The light spot of this camera is two-way talk and audio and light warming function. Although it has a pretty big CMOS sensor (1/2.7” ), there are still plenty picture noise and motion blur. 5441-pv seems to has a poor performance in terms of night vision.Small motion blur and picture noise and has more AI function than 2431. However If you force 2831 to color mode, serious motion blur will be produced. 2831 is more likely to stay IR mode than color mode in a lowlight environment at night.(same envirnment, 2831 is BW and 2431 is color).If you want your camera has some AI functions, like SMD or Smart IVS, new 3 series lite AI camera (3441) is also a good option. 2431 is the most cost-effective camera in terms of night vision.However, the FullColor camera still provided a color image due to its LED light supplement lamp.Īccording to the observations above, the form was created in order to help you compare the night performance of these cameras much more easily. Under this totally dark condition, 7 cameras were switched to the IR mode because the light was so weak that it could not reach the minimum illumination of the camera. In scenario 2, all cameras were installed in a dark room in order to stimulate a complete dark environment. However, there is plenty serious motion blur if the image is not static. The image quality of 2831 improved after being switched to the color mode and the image even reached to the level of 2431. As such, if we manually change 4631, 48 to a color mode, what will happen? It was strange that although 24 were both Dahua’s new-generation starlight cameras, 2831 is in IR mode in the same environment compared to 2431’s color picture. It is clear that 5442-led, 5442, 5541, 34 provided color pictures in auto mode (Default settings-cameras automatically choose the color image or B/W image), whereas black/white images were shown in 2831, 46. When a camera was tested, the IR or LED lights of the other cameras were covered by black tapes in order to eliminate the influence. In scenario 1, eight cameras were installed in front of the door and were tested one by one, with some road lamps under this condition.
