Description

Technical Field

[0001] The utility model relates to the technical field of network cameras, in particular to a binocular panoramic 220-degree intelligent integrated ball camera based on HiSilicon HISI3402. Background Art

[0002] Smart dome cameras represent the evolution of modern television surveillance. They integrate a color all-in-one camera, pan / tilt head (PTZ), decoder, and protective cover, making them easy to install and use, yet powerful. They are widely used for monitoring large open areas and can be used in a variety of situations. However, existing, common monocular dome cameras have several drawbacks when used for surveillance: First, their viewing angle is limited, typically only covering the camera's fixed area and not the entire room. This also means that when monitoring a larger area, multiple cameras must be installed, increasing investment costs. Second, due to the design characteristics of the spherical camera, portions of the camera may be obscured by surrounding objects, affecting monitoring effectiveness. Utility Model Content
