The invention relates to a monitorable street lamp. The monitorable street lamp is characterized by comprising an electricity generating assembly, a lighting assembly, a monitoring assembly and a supporting assembly; the electricity generating assembly is positioned in the supporting assembly and at the upper end of the supporting assembly; the lighting assembly is arranged at the top end of one side of the supporting assembly; the monitoring assembly is fixed on the outer wall of the supporting assembly; the supporting assembly is fixed on the ground; the electricity generating assembly comprises a photovoltaic panel and storage batteries; the photovoltaic panel is fixed at the top end of a hydraulic telescopic lamp post; and the storage battery group is arranged in a street lamp pedestal. The whole technical scheme is compact in structure, low in cost, energy-saving and environmentally-friendly. According to the technical scheme, the monitoring equipment is added on the basis of the design of the original traditional lighting street lamp, so the monitorable street lamp has the night lighting function and also has the functions of monitoring in real time, recording and saving. The monitorable street lamp can be conveniently added into an urban road monitoring network or a safety monitoring network, so the cost required by installation of an urban monitoring system is greatly saved.
