Abstract:
A pan-tilt-zoom device identification method, a pan-tilt-zoom device, a camera, and a pan-tilt-zoom device control system are provided. The corresponding method includes, when a pan-tilt-zoom device finds that a device connects to a predetermined interface, sending a keep-alive command to the connecting device, where the keep-alive command includes pan-tilt-zoom device capability information carrying a control function of the pan-tilt-zoom device; and determining, by the connecting device, the control function of the pan-tilt-zoom device according to the keep-alive command, and reporting control capability information of the pan-tilt-zoom device.
