Security monitoring system and control method thereof

Abstract

The invention belongs to the technical field of monitoring equipment, and specifically relates to a security monitoring system and a control method thereof. The security monitoring system comprises abase and a camera body used for monitoring; the security monitoring system further comprises a dustproof and water proof protection device and a controller; the controller is used for controlling thework of equipment; the camera body is installed inside the protection device through the base; the protection device comprises a protective shell, a light-transmitting hole, a sponge brush, high-permeability glass, a No.1 mounting plate, a No.2 mounting plate, a driving gear, a limiting gear, a No.1 rotating shaft, a No.2 rotating shaft, an annular sliding groove, an annular gear, a slider and a micro speed regulating motor; and the protective shell is of a horizontally-arranged cylindrical hollow structure, and one side, far away from the base, of the protective shell is provided with the light-transmitting hole. According to the security monitoring system provided by the invention, the protection device is arranged on the camera body, so that a camera is protected, and dust under a mineis prevented from covering the camera body, thus a monitored picture is ensured not to be shielded.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment, in particular to a security monitoring system and a control method thereof. 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 record.
