The invention discloses an automatic control method for surveillance cameras based on a virtual reality technology. The method includes the steps that a three-dimensional virtual scene is modeled and generated according to an electrical equipment monitoring scene; electrical equipment needing to be monitored is searched for and positioned; the best surveillance camera for monitoring the electrical equipment is positioned; the rotation angle of the surveillance camera which is adjusted to the electrical equipment is calculated; the surveillance camera is adjusted according to the rotation angle. By means of the automatic control method for the surveillance cameras based on the virtual reality technology, the defects that the needed time is long and the effect is poor when the surveillance cameras are adjusted manually can be overcome, operation information of the electrical equipment can be acquired in time, and the monitoring quality of the electrical equipment is improved.
