The invention discloses monitoring equipment applied to construction project costs. The structure includes a bracket, a switchgear, an infrared lamp, a camera, a frame, a top cover, a machine body, amotor, a wire, a storage battery and a heat collection plate, wherein the machine body is a cuboid structure and has a height of 15cm, a length of 35cm and a width of 10cm, the bracket is welded at the bottom of the machine body, and the bracket is an L-shaped structure. According to the monitoring equipment applied to the construction project costs disclosed by the invention, the heat collectionplate is arranged, solar energy is absorbed through a heat collection plate main body in the heat collection plate, the solar energy is stored in a solar chip, and then the solar energy in the solar chip is transmitted to the storage battery by using the wire, and then the solar energy is converted into electric energy, the electric energy can be transmitted to the monitoring equipment at any time, the phenomenon that the monitoring equipment has power shortage can be prevented, and thus pictures of the monitoring equipment can be clearer.
