The invention relates to the field of auxiliary monitoring, in particular to novel video monitoring equipment with an adjustable monitoring height. The novel video monitoring equipment comprises a bottom plate, a motor is installed in the middle of the upper end of the bottom plate, an output shaft is installed at the upper end of the motor, a non-full-tooth gear is fixed to the lower portion of the output shaft, and a hollow inner tooth frame is meshed with the outer side of the non-full-tooth gear. A piston plate is fixed at the other end of the hollow inner tooth frame. An electronic vent valve is installed in the middle of the piston plate, a piston cylinder is connected to the outer side of the piston plate in a sliding mode, and the non-full-tooth gear, the hollow inner tooth frame,the piston plate, the electronic vent valve, an electronic one-way air inlet valve, an electronic one-way air outlet valve, a sealing lifting device, a lifting supporting device, thus under the actionof a motor, the height of
