    IPC-color-4K-X IVS issue

    Dahua SMD 3.0 will filter animals. You can set the SMD sensitivity. SMD 3.0 can distinguish between people and cars. Instead, I think the old SMD is better to use. In addition, the firmware V2.800.15OG004.0.R cannot run the CMOS of HFW5849T1 Firmware version V2.840 or later must be used.
