The invention discloses a construction quality remote checking and accepting system and method. The system comprises an audio and video collecting front-end, a mobile collecting and transmitting terminal and a back-end host, wherein the audio and video collecting front-end is arranged on a construction site and is used for collecting site data of the construction site; the mobile collecting and transmitting terminal receives the site data collected by the audio and video colleting front-end in a wireless mode or in a wired mode, processes the site data and transmits the processed site data to the back-end host through a wireless network device, and after receiving a control command of the back-end host, the mobile collecting and transmitting terminal correspondingly controls the audio and video collecting front-end; the back-end host receives the site data transmitted by the mobile collecting and transmitting terminal and sends the control command according to the site data or checks and accepts the site data. By the adoption of the construction quality remote checking and accepting system and method, construction quality checking and acceptance can be conducted in a place which is not the site, the data can be checked in real time, and front staff and backstage staff can conduct real-time communication.
