[0002] The weak current system of intelligent buildings is a basic member of the intelligent group in intelligent buildings and a key component of intelligent buildings. The design content of weak current design is expanding step by step, the technology is getting newer and the workload is getting bigger. In weak current engineering, security monitoring devices are needed;

[0003] However, the existing monitoring devices are usually composed of components such as cameras, manual or electric lenses, pan / tilt heads, protective covers, listeners, alarm detectors and multi-function decoders. They each have their own functions and establish corresponding connections with various devices of the central control system through wired, wireless or optical fiber transmission media (transmitting video / audio signals and control and alarm signals). They are devices that can remotely view and monitor an area. The monitoring device can monitor an area within a full 24 hours, prevent fire and theft, and provide real-time monitoring and alarms. It can greatly reduce labor costs, monitor in real time and save images. However, since the monitoring equipment is fixed in a certain position, when the monitoring angle needs to be adjusted, the staff needs to disassemble the monitor and then reinstall it at the specified monitoring angle. This increases the workload of the staff and wastes their time. For this reason, we have proposed a weak current engineering security monitoring device. Utility Model Content
