An oil pressure damper device for an architectural structure and a monitor and control system of the damper device without requiring an exclusive network for connecting between the damper devices and the monitor and control system, and is able to monitor operations without regard to the distance between the damper devices and the monitor system. The oil pressure damper device includes a detection unit for detecting conditions of the damper device, a communication unit for transmitting information detected by the detection unit through a public communication network and/or a local area network, and a monitor for receiving the information from the communication unit and monitoring the conditions of the damper devices of the architectural structure.
