Description

Technical Field

[0001] The utility model relates to the technical field of security monitoring, in particular to a security monitoring device used for weak current engineering. Background Art

[0002] The monitoring system is one of the most widely used systems in the security system. The more suitable construction site monitoring system on the market now is the handheld video communication device. Video monitoring is now the mainstream. From the earliest analog monitoring to the popular digital monitoring in the past few years to the emerging network video monitoring, earth-shaking changes have taken place. Today, when IP technology is gradually unifying the world, it is necessary for us to re-understand the development history of video monitoring systems. Installing monitoring can not only prevent theft, but also assist people in investigating the truth of many things and help to demarcate the responsibility of the case.

[0003] The existing security monitoring equipment has a relatively fixed structure and is difficult to adjust according to the required position. It is also not easy to dissipate heat during use, which affects the service life of the monitoring equipment and brings inconvenience to the user.

[0004] For example, a security monitoring device for weak current engineering disclosed in Chinese patent CN217815819U has a heat dissipation mechanism, a rotating shaft three is fixedly connected to the output end of the motor, and a fan blade is fixedly connected to the outer side of the rotating shaft three. After the motor is driven, the fan blade blows air to the inside of the device to dissipate the internal temperature. A heat dissipation net is fixedly connected to one side of the top of the monitoring device body, and the heat energy is dissipated to the outside through the heat dissipation net. The rotating mechanism is set so that the device can be rotated according to the required position. The automatic telescopic rod two is fixed to the top of the base with bolts and the fixed block three. The top of the base is fixedly connected with a rotating block, and the rotating block is rotatably connected to the fixed block one through the rotating shaft two. When different rotation angles are required, the rotation angle of the device is controlled by the automatic telescopic rod two, and then it can be adjusted according to the position required for device monitoring. Therefore, the heat dissipation mechanism can improve internal heat dissipation, so that the device can be used for a long time to increase its service life.

[0005] However, the height and angle of the camera cannot be adjusted during use, and the monitoring range is small, which reduces the practicality of the monitoring equipment.

[0006] For this reason, we urgently need to provide a security monitoring device for weak current engineering. Utility Model Content
