is there a mirror site of XM (xiongmaitech) IPC firmwares ?

[G33RT]

Does someone knows if there is any mirror site of the XM (xiongmaitech) IPC firmwares ?

Many of the firmwares I need have expired and can't be downloaded anymore like:

00002510.1版IPC50H10L_S38_V4.02.R11 (xm030.cn)
00006531.1版IPC18E_53H13_S38_V4.0.R12 (xm030.cn)

Thanks in advance !
