Hi Euly, unfortunately there I cannot help you. I rechecked the two sites where I found firmware and none of the available images indicates IVS support. Update: I was at the customer's site where I installed those two 4216s yesterday, and in the General Settings menu, there is an enable IVS checkbox in the firmware I posted above. Seems like it does include IVS support after all!

I'm seeking the latest firmware for a Dahua 4216-8P. I believe it's the same build for all of the 42XX series NVRs. I have had zero luck contacting Dahua or my seller unfortunately. Can anyone help? Thanks! Update: Unsurprisingly perhaps, I never heard back from Dahua after several attempts and a week of waiting, but using the system number and common strings from other firmwares posted here as search parameters, I tracked down the latest firmware dated 11/20/2015 for the 4xxx series NVR on a Chinese language FTP share. Of course YMMV as I didn't get this from Dahua directly, but I can confirm it loaded successfully and works well on two 4216-8Ps: http://upstore.net/EqBDBog
