Looks that way
could this include the focus fix (optimize focus) that I personally have been requesting for months now! shall try it later and report back.Jim_OS has just spotted Dahua have added new firmware which mentions addressing a focus issue, this might be the resolution

OK, who's going to be the guinea pig with this FW?
Well I was last time, amongst a few others! based on the current flickering and focus issues with the last version I will probably bite the bullet later today, what could possibly go wrong
This sounds positive, were you seeing focus problems on the previous version at all?

That does sound promising.
After CC does the FW upgrade and confirms, I'll take the plunge.
No pressure then
Update 2nd April - new firmware installed, no major shocks and functions OK, very early days, flickering still visible during both day and night which is disappointing, original firmware the camera shipped with never had this and Dahua are very much aware. Will let the dust settle in the next 48 hours and should know by then how the focus is behaving, so far it seems to be improved. In the meantime assuming this beast doesn't start letting in water or quit on me altogether then I stand by my original assessment that the 49225 is a great piece of kit even with these firmware gremlins. I just wish Dahua could cram the same image quality into a 5231 style body minus the beefy IR lighting of course, the 49225 really does put the smaller Dahua model to shame and my guess is that this is down the the glass/lens used in the PTZ model. Shall update this once I've properly tested the new firmware.
4th April - flickering during night and day is worse than the last firmware version which is plain annoying, focus seems to be better and so far mine has not tripped up - that is very good news. I know the flickering is a firmware problem since the original version it shipped with was flicker free, I have raised it with Dahua on numerous occasions and they think I am imagining it
If the flickering gets much worse it will start tripping motion detection

Don't want to upgrade to flicker, not good.
Thanks Fred, appreciate the info.

CC, maybe you have another piece of equipment causing the flashing issue?
No, sadly not, all other cameras fine, only occurred after the previous firmware update
before that there was zero flickering.

Just wondering if you went straight to a switch or router it would change anything.No, sadly not, all other cameras fine, only occurred after the previous firmware update
That blows!
