Installation mechanism, security and protection monitoring device and security and protection monitoring system

Abstract

The invention relates to the technical field of security and protection, in particular to an installation mechanism, a security and protection monitoring device and a security and protection monitoring system. The installation mechanism is used for installing a displacement detection part, and comprises a first shell (1) and a second shell (2), a first cavity (3) is arranged in the first shell (1), the second shell (2) can arranged in the first cavity (3) of the first shell (1) in a sliding mode, and a second cavity used for installing the displacement detection part is arranged in the second shell (2). According to the installation mechanism, the second shell is driven to slide or roll in the first cavity due to slight moving of the first shell, and displacement detection can be achieved after the displacement detection part is disposed in the second shell. Displacement detection can be achieved as long as the installation mechanism is arranged on an independent monitored object, and accordingly the problem that traditional door sensors have to be installed on two opposite and separated positions to achieve displacement detection is solved.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an installation mechanism for installing a security monitoring device, a security monitoring device and a security monitoring system using the installation mechanism. Background technique [0002] At present, the door sensor is the most commonly used security monitoring device. The door sensor includes a door sensor host (main controller) and a magnet body. Such as figure 1 As shown, the magnet body 10 and the door magnet host 20 are installed on the door frame 30 and the door body 40 respectively. When the door is closed, the position of the magnet body and the door sensor host is fixed, and the door sensor is in a stable state; when the door is opened, the magnet body is far away from the door sensor host, triggering an alarm and realizing security monitoring. However, since the magnet body and the door magnetic host must be installed in two relatively separated positions t...

AI Technical Summary

Problems solved by technology

However, since the magnet body and the door magnetic host must be installed in two relatively separated positions to achieve security alarms, there are the following disadvantages: the installation method is not flexible; it is not suitable for monitoring an independent object, and the scope of application is small; the door sensor is used for glass When the window is opened, the alarm can only be triggered when the glass window changes from the closed state to the open state. If the glass window itself is in the open state, security monitoring cannot be realized when it is opened illegally.
