Selection of spherical PT and non-spherical PT in video surveillance

    The spherical PTZ and non-spherical PTZ in the field of video surveillance is divided according to the differences of their appearance in the industry, so as to be used by the entire security monitoring industry.


On related professional media and websites, there are very few descriptions and explanations of the spherical PTZ and the non-spherical PTZ. The only descriptions are only used to distinguish the concept of a dome camera and a box PTZ camera from the perspective of large security. Therefore, this article only analyzes the spherical PTZ and aspherical PTZ used in the areas that need a large field of vision and a wide range of video surveillance such as forest fire monitoring, high altitude lookout, channel (river) video surveillance, border&coastal surveillance and other fields, so that the users can have a better understanding, screening and selection of the PTZs.


The basic functions achieved by both spherical PTZ and non-spherical PTZ in the field of intelligent video surveillance are the same, the internal functional modules are basically the same, to build zoom lens integrated camera in the camera housing, and then fix the camera housing to the PT to pan/tilt, left and right rotation and capture video / images.


1. To select the PTZ through the appearance


The non-spherical PTZ is to fix the camera housing with a camera onto the top plate of the PT (square tube or cylindrical), there are a variety of functional circuit boards and drive motor inside the PT, and it can be 360 ° continuous rotation in horizon and -60 ° ~ 60 ° in vertical rotation. Some high-performance non-spherical PTZ can also set the operation mode, such as "chipping apple" mode, horizontal continuous rotation mode and overcast, rainy, sunny and other modes, the user can select the corresponding operation mode according to the weather conditions and seasons.


Non-spherical PTZ reduces the size and weight of the camera housing maximumly. However, this can not be considered that the appearance of non-spherical PTZs camera housing is not beautiful. In many non-spherical PTZ equipment, the corners of the camera housing are more chamfered, streamlined design, easy to handle for the staffs as well as considering the wind resistance.


The spherical PTZ is to fix the camera housing with a camera onto the top plate of the PT , there are a variety of functional circuit boards and drive motor inside the PT, and it can be 360 ° continuous rotation in horizon and -60 ° ~ 60 ° in vertical rotation, some vertical angel even bigger. In the case of the same basic functions, the spherical PTZ increases the size and weight of the spherical camera housing in pursuit of beauty and reducing the wind resistance of the rectangular camera housing, which increases the difficulty of manufacturing and the power consumption of equipment operation, increases the input cost of the overall monitoring system, and brings about a series of difficulties in handling, installation and maintenance in the later period.
