Portable and transmission-distance-adjustable monitoring pan-tilt

Abstract

The invention relates to the technical field of security monitoring, and discloses a portable and transmission-distance-adjustable monitoring pan-tilt. The pan-tilt includes a datum block, a first lifting table is clamped in the datum block in a rotating mode, through arrangement of the first lifting table, a second lifting table, a third lifting table, teeth, a mounting block, a stop pin, gears,and double-sided racks, the portable and transmission-distance-adjustable monitoring pan-tilt can rise a camera, so that a control signal received by a decoder is strong, the decoder can carry out remote control on a video camera and the pan-tilt, the monitoring range is larger, and the range of security monitoring is improved. Through arrangement of a support rod, an arc block, a bearing table, alead screw, and a dust-proof shield, the video camera is arranged on the most upper part of the device without hanging, the operating load of the pan-tilt is small and is not prone to being damaged,camera lens can be automatically operated to rotate flexibly, the pan-tilt mechanism is not prone to being damaged, the monitoring quality is good, and the safety is high for people.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a portable monitoring platform with adjustable transmission distance. 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. The pan / tilt is the supporting device of the security monitoring system. [0003] The gimbal is mostly installed in the way of hoisting, because the total weight of the camera and its protective cover often exceeds the bearing capacity of the gimbal, the hoisting method will easily lead to a large operating load of the gimbal, the gimbal cannot rotate, and the rotating mechanism will be damaged or even burned Motor, and when the transmission distance is too long, it is not easy to monitor a particularly large range if the monitor is too low, the control signal ...

[0003] The gimbal is mostly installed in the way of hoisting, because the total weight of the camera and its protective cover often exceeds the bearing capacity of the gimbal, the hoisting method will easily lead to a large operating load of the gimbal, the gimbal cannot rotate, and the rotating mechanism will be damaged or even burned Motor, and when the transmission distance is too long, it is not easy to monitor a particularly large range if the monitor is too low, the control signal attenuation is too large, the control signal received by the decoder is too weak, and it is impossible to remotely control the camera and pan / tilt through the decoder, which affects Security monitoring scope and quality
