Security cameras for elevator doors

Abstract

The present invention relates to a security camera device for monitoring the outside of an elevator having a monitor installed therein, comprising: a surveillance camera (10) installed on the surface of a cage door (D1) of the elevator; an infrared lamp (20) installed adjacent to the surveillance camera (10) to illuminate a corridor of a building at night; a detection unit (30) that detects when the cage door (D1) accurately coincides with a hall door (D2) of the elevator; a window (W) formed in the hall door (D2) to correspond to the front of the surveillance camera (10) and the infrared lamp (20) and covered with a transparent glass, the window (W) having a size sufficient to cover the viewing angle (A) of the surveillance camera (10); and a controller (40) connected to the surveillance camera, the infrared lamp, and the detection unit to control the operation of these elements and store data, wherein the surveillance camera (10) usually photographs a moving image and photographs a still image under control of the controller when the detection unit (30) detects that both the doors (D1, D2) accurately coincide with each other, and the controller controls the monitor (M) to display the moving image and the still image that are photographed by the surveillance camera.

Description

technical field [0001] The present invention relates to a security camera device for elevator doors, and more particularly, to a security camera device for monitoring the exterior of an elevator provided with a display. Background technique [0002] For the safety of elevator passengers, the situation that anti-theft windows are set at elevator doors is increasing day by day recently. Such antitheft windows are required not only to ensure the safety of elevator passengers but also to ensure the safety of the outside of elevators such as corridors of buildings. [0003] Figure 1A , Figure 1B Shown is an existing lift with security windows, Figure 1A is the front view of the elevator door, Figure 1B as along Figure 1A The cross-sectional view of the B-B line, together with the illustration of the hoistway. [0004] As shown in the figure, if anti-theft windows W1~W2 are installed on the elevator doors, not only the passenger P1 in the elevator can be confirmed in the c...
