ian_flux 0 Posted September 1, 2015 Hello all, I'm looking for the latest/last firmware/bios for a Ganz ZR-DHD921NP. I'm running 1.11. Firmware is available (v1.50) for the ZR-DH1621NP on the Ganz website (http://ganzsecurity.com/product/433/ZR-DH1621NP) even though the model is long discontinued but I can't find it specifically for the ZR-DHD921NP. Contact with the UK office has provided an unhelpful answer that the model is "no longer supported". Can anyone get hold of firmware from a unit that they have access to, or as a last resort tell me if the DH1621 firmware would work on the DHD921? Thanks Ian Share this post Link to post Share on other sites
