V402r11 H264 H265 Dvr Nvr Firmware Download Fix — Work

The "work" involves deciphering cryptic file names. A user might find XM_V402R11_Hi3536_8MP.bin and wonder if it fits their 4MP system. Flashing the wrong variant (e.g., a Hi3521 file onto a Hi3536 board) is the most common cause of hardware failure in this category.
