Title:
DIRECTIONAL ANTENNA-BASED ROTATABLE CAMERA ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/005398
Kind Code:
A1
Abstract:
A directional antenna-based rotatable camera assembly, comprising: a video image acquisition device and an antenna assembly. The antenna assembly comprises a directional antenna, a motor, a wireless circuit, and a controller assembly. The motor is connected to the directional antenna and is used for driving the directional antenna to rotate, so that the directional antenna faces different directions; the wireless circuit is electrically connected to the directional antenna; the controller assembly is electrically connected to the wireless circuit and the motor, and is used for controlling the motor to rotate towards a direction in which a communication performance value reaches a first performance threshold; the video image acquisition device is connected to the wireless circuit; and when the directional antenna rotates to the direction of the first performance threshold, the video image acquisition device sends an acquired video image by means of the directional antenna.
