HI,
Thanks for this topic. I have several Dahua IPC-HFW4300S-V2 cameras. Recently I ordered a few more and had trouble with the scheduled snap shot mode. The cameras were set up to save a snapshot every 5 seconds to a FTP server but would not restart sending snapshots after a power down unless I re-entered the schedule after setting the schedule to default. This happened on both serial numbered cameras starting with PZC4L and 1E017. .
The PZC4L would only accept:
DH_IPC-HX5(4)XXX_Eng_N_Stream3_V2.420.0000.0.R.20140419 and it fixed the problem.
The 1E017 would only accept:
General_IPC-4300S_Stream3_V2.420.0002.0.R.20140621_a and it fixed the problem.
I used the Web interface to change the firmware to an older version.
I found the firmwares at the link listed earlier in this topic.
Thanks a bunch for listing the firmware. Just thought I'd pass this along. I spent a fair amount of time trying to find firmware that would load into the respective serial numbered cameras.
