Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, and more specifically, to a monitoring equipment for an elevator car. Background Art

[0002] Cameras are usually installed in elevator cars to monitor the interior of the elevator. The cameras are usually installed at the top corners of the car near the inside. Large decoration materials or furniture are often transported in elevators. These items are high and can easily hit the camera accidentally when being moved in, causing damage to the camera and resulting in economic losses. In addition, the angle and pitch angle of the camera are mostly fixed during installation, which makes it difficult to adjust them at any time according to usage requirements in the later stage, making it inconvenient to use. At the same time, the camera is mostly connected by multiple bolts during installation, which means that when the camera is repaired later, multiple bolts need to be removed one by one before the camera can be removed for repair or replacement.
