     FIELD OF TECHNOLOGY 
     The present invention relates to the field of cameras. In particular, it relates to A pan-tilt-zoom camera for omni-directional 360-degree-detection and 360-degree surveillance method. 
     BACKGROUND 
     The pan-tilt-zoom is a supporting device for installing and fixing the camera. It is divided into two types: fixed and electric pan-tilt-zoom. The fixed pan-tilt-zoom is suitable for situations where the monitoring range is not large. After installing the camera on the fixed pan-tilt-zoom, you can adjust the level and tilt of the camera. After reaching the best working posture, you only need to lock the adjustment mechanism. The electric pan/tilt is suitable for scanning and monitoring a large area, and it can expand the monitoring range of the camera. However, in order to achieve 360-degree rotation, the current electric pan/tilt cameras on the market mostly use rotating mechanisms with complex structures, such as industrial multi-way slip rings, which have complex structures and high manufacturing costs. The complex structure also increases the product failure rate. Reduced reliability. 
     Domestic patent publication number CN209201182U relates to a panoramic cooperative control camera. A panoramic cooperative control camera includes a panoramic camera, a mounting bottom case, and a cooperative control component. In the panoramic cooperative control camera of the utility model, a shield of the panoramic camera as a whole rotates up and down through a driving motor and a conveying belt, thereby implementing the remotely electric adjustment of top and bottom viewing angles of the panoramic camera through programs and satisfying requirements for monitoring of different top and bottom viewing angles and installation heights on project fields. The innovative design of the mounting bottom case satisfies waterproofing requirements of wiring to facilitate installation and maintenance. Various forms of (ballhead camera and pan head) PTZ cooperative control cameras in the market as cooperative control components are supported, so that the product faces the market in the cooperative control form of panoramic camera+ballhead camera or panoramic camera+pan head. In addition, private network exchange, power distribution assembly, and RS485 control interface circuit are additionally provided in the panoramic camera, reducing required power supplies and network cables from an equipment cabinet to a front-end device, thereby helping a remote control device to perform coordinated operation and work as a whole. The panoramic camera has complex structure. Therefore, when the panoramic camera fails, it needs to be repaired by professionals, with high cost.
