The present invention discloses an intelligent security apparatus for container, a mechatronic customs seal and a bracket, a bracket, internally installed with an antenna, a processing circuit and power with electrical connection thereamong and mounted on a door of a container; a hole for fitting a customs seal, opened on the bracket; and a mechatronic customs seal, internally provided with a detecting wire and a chip written with ID code and inserted through the hole in the bracket and lock rod handle; wherein the mechatronic customs seal is inserted in the hole of the bracket, the detecting wire and the chip written with ID code in the mechatronic customs seal is electrically connected to the processing circuit in the bracket. The intelligent security apparatus provided by the present invention has physical seal structure and electrical real-time monitoring function at the same time. While checking the integrality of the physical structure via visual observation, the apparatus can also perform electrical real-time monitoring and recording for the seal status. By adopting the principle of integrating mechanism and electronics, the mechatronic customs seal enables electrical detection and one-off physical structure, which ensures high security; the data storing and transmitting section of the bracket are reusable, and hence solve the problem of costly traditional one-off electrical seal.
