1. A surveillance method using a monitoring station, the monitoring station electronically communicating with an actuator, an image capture device, and a plurality of motion sensors, the method comprising: detecting presence of motion in a monitored area in real-time using the motion sensors; determining a target region in the monitored area where the motion is detected according to which of the motion sensors detects the motion when the motion is detected, the motion sensors prioritized according to a predetermined importance of each motion sensor and each of the motion sensors being located to cover a target region in the monitored area; when two or more of the motion sensors simultaneously detect motion, the target region determined according to a covered target region of one of the two or more motion sensors having a higher priority; sending a control signal to the actuator according to the target region where the motion is detected; controlling the image capture device to aim at the target region using the actuator according to the control signal; capturing real-time images of the target region using the image capture device; and storing the captured images in a storage system of the monitoring station.
