Security monitoring device with alarm anti-theft function and use method

Abstract

The invention discloses a security monitoring device with an alarm anti-theft function and a use method, and belongs to the technical field of security monitoring. The security monitoring device comprises a mounting cylinder, a touch alarm mechanism is arranged on the mounting cylinder, a transparent cover is clamped to the outer side of the touch alarm mechanism, a chassis is attached to the lower surface of the transparent cover, and the lower surface of the chassis is fixedly connected with the top end of a dust removal mechanism; the dust removal mechanism is fixedly connected to the lower surface of the chassis and provided with a cleaning mechanism. According to the invention, the touch alarm mechanism is arranged, if the camera needs to be operated, a transparent cover needs to be lifted to move upwards, the transparent cover drives a fixing sleeve to move upwards, the fixing sleeve can extrude a contact switch, and the contact switch is extruded to transmit information to an alarm, so that the alarm can be ensured; the first spring can extend through self elasticity to push the circular plate to move downwards, and the circular plate can drive the fixing sleeve to move downwards, so that the transparent cover can effectively cover the chassis to effectively protect the camera.

Description

technical field [0001] The invention belongs to the technical field of security monitoring, in particular to a security monitoring with an alarm and anti-theft function and a use method. Background technique [0002] The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and forms an independent and complete system from camera to image display and recording. It can reflect the monitored object in real time, vividly and truly, not only greatly extending the observation distance of the human eye, but also expanding the function of the human eye. It can replace manual monitoring for a long time in harsh environments, allowing people to see Everything that actually happened at the monitored site was recorded by a video recorder. At the same time, the alarm system equipment alarms the illegal intrusion, and the generated alarm signal is input to the alarm host, which triggers the monitoring system to record and...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing cameras are generally exposed outside, not only vulnerable to damage and may be stolen, but the existing security monitoring does not have an alarm function, so even if the camera is stolen It cannot be found in a timely and effective manner. At the same time, the installation parts of the existing cameras are generally metal components such as bolts. Although they can be installed stably, long-term exposure to the sun and rain will cause rust and corrosion of the metal components, which may lead to breakage and damage of the metal components. Fixing the camera brings great inconvenience to the installation and disassembly of the camera, and if the camera is loose, the shooting angle may change and affect the normal monitoring work. The security monitoring and use method with alarm and anti-theft function is proposed
