Systems and methods are provided for preventing a door from contacting an obstacle. One system includes a camera, a sensor, and a controller. The camera and the sensor are each configured to detect if the obstacle is within a path of the door. Another system includes an ultrasonic sensor, a near field sensor, and a controller. The ultrasonic sensor and the near field sensor are each configured to detect if the obstacle is within a path of the door. The controller in each system is configured to disable the door if the obstacle is detected within the path. One method includes the steps of visually or non-visually detecting if an obstacle is within an opening/closing path of a door when the obstacle is within or outside a camera field of view, respectively, and disabling the door if the obstacle is detected.
