Hikvison was trying to steal Dahua's HDCVI solution and been caught red handed. certainly Hikvision don't have enough confidence of their own technology.
This incident has gone viral. Dahua demand answer from government level (Hikvision is government funded company).
Have to see how this incident gonna influence the future competition of those two CCTV giants.
