基于Realtek RTL8715AH的Wi-Fi camera and doorbell 方案

随著IOT物联网应用的发展,在智慧家庭上也推出门铃摄影机产品. 基于Realtek Ameba pro RTL8715AH,one single chip整合了Wi-Fi + Codec + Memory + Video + dual CPU. 在使用上,不论家中是否有人,只要有人到访,立刻就可以透过APP知道,并且可以即时对话,以及保存影像.
  • Wi-Fi支援Wi-Fi 5G AC,影像传输顺畅延迟低.
  •  影像支援1080P full HD 30FPS, image sensor在夜间拍摄及省电上也有良好的表现.
  • 使用18650电池*2.
