SD59225U-HNI Stereo video analysis

The growth of AI applications has enabled the greater availability of 3D scene analysis solutions, thereby enabling objects and people to be analysed in three dimensions.

Dahua Technology’s stereo analysis uses two lenses, in order to capture separate images of the same scene. It then computes the ‘optical parallax’ of spatial points in the two images, providing 3D information of the scene. The stereo vision mimics the depth of view that comes from humans having two eyes, known as binocular vision.

SD59225U-HNI Specific Pan & Tilt Cruise.

Frying pan & Tilt as the core elements of network PTZ dome cam, it is likewise the crucial factor why PTZ dome cam is made up the majority of the market share in business video security applications. As the essential component of PTZ dome camera, it presents the innovative modern technology of motor mechanical structure and control, it’s the driving power to frying pan & tilt cam. The smooth running of pan & tilt turning depends on whether the equipped motor’s performance is superb. Currently, the widely used motors consist of 2 kinds: DC electric motor as well as Stepper electric motor. All the dome cams in this examination adopt stepper motors, stepper electric motor works establish its pulse checking can be driven below the distinct control systems. To revolve the video camera from one placement to an additional position, at a constant rate, only requires to determine the difference of number of actions between the two locations. Due to this turning style, PTZ electronic camera is suitable for huge area video monitoring.

SD59225U-HNI High Clarity in Genuine Tracking Scene.

In real-time tracking scene, the modifications of setting may bring some difficulties to network speed dome cam. Such as fog, solid light, rain-storm etc, these 4 PTZ cams are able to withstand/overcome the severe problems to supply hd video.

SD59225U-HNI Low Illumination Performance.

Low lighting is one of important elements to evaluate protection video camera performance. Put network cameras right into dark box, as we manually reduce the lighting to inspect the threshold value when video cameras change image mode from shade to monochrome. Among them, Dahua and also Uniview, along with Tiandy have much better efficiency, When Dahua network electronic camera works in minimal illumination is 0.00 Lux ( actual Lux is in the variety of 0.001 – 0.009 Lux) condition, the camera still can capture clear pictures, and virtually no picture sound, its reduced lighting efficiency is excellent.
