The situation I had was that I wanted to set the camera in a portrait orientation so that I can view part of the house and a narrow long driveway.
After a few minutes on the phone with Armsec (massive thanks for that guys!) I’ve got it all sorted. So I thought that I would make this post for whoever may be interested in doing the same!
I had a dome camera with a 3-axis adjustable lens. So the first thing I did was to pull the cover off and rotated the lens. It sorted half of the problem – now I could see the whole driveway but I had to turn my head side-ways to view it.
So the next thing I did was to use what Hikvision calls ROTATE MODE and, as the name suggests, it flips the picture by 90°. Unfortunately, for some reason, the mode was disabled (greyed out) and I could not change it.
So this is where the tech help was handy – following their instructions I updated the firmware (I wont go into detail here as I’ve seen there is a post on this already) and then temporarily switched off the default H.264+ compression in the Camera Configurations. I then rotated the picture!
PS: Once you’ve flipped the picture you can set H.264+ back on if you choose to do so.
Hope this helps!
Thanks for sharing!

Tnks for your help with this!
@CrzFrog Thanks!
Hi, I've got an issue with the rotate mode ... I have two cameras - one on the wall the other soffit - the one on the wall I want to rotate so that it looks down the driveway. When I check the pciture in the browser - all is ok but when I log into my synology, the picture is extremely pixelated and low quality.
Does anyone have the same issue?
I think that's because synology makes it a bit more difficult to process and adjust for the rotation, so it basically flips the picture - so, say, if you have 2560 x 1600 resolution, when you use the corridor mode it just flips it to 1600 x 2560.
I think the best thing in that case would be to physically rotate the lens if your camera allows for it!
@CrzFrog Thanks! Will try
I'm using 3 turrets (DS-2CD2355FWD-I) in portrait and I want to rotate the streams rather than turn the displays in the client app.
If I try the Rotate option in the web interface I get this message for a second and nothing happens.
"Encoding performance reaches its limit".
I tried Googling for that but not much useful found.
Turning off H265 didn't help
Anyone have any ideas?
After months of wondering about this and not finding any explanation for this message, I have found an answer (sort of). The reason I want to retain portrait mode because that covers the specific areas much better.
It seems the Rotate option fails if the resolution is set to 3072x2048. Anything below this and you get a Save successful" message and the stream rotates by 90 degrees.
Unfortunately for me, this is in the wrong direction and the images are now upside-down but I can deal with that by getting up the ladder and rotating all the cameras 180 degrees.
(For reference, the correct way up needs to be with the the camera lens above and IR below.) Its a pity the Rotate function doesn't give the option of 90/180/270 degrees.
So to confirm, I'm using 3072x1728 H256+ and that's okay. Just a bit narrower than the images were before.
I hope this information may be useful to others.
I think it might have something to do with the maximum encoding capacity of your recorder. Quite a while ago I had Dahua 4MP NVR but used 5MP cameras. The cameras' resolution was set to 2560 x 1440 (i.e. c. 4MP) and all was fine. However, if I tried to switch it to 5MP, it would show my a similar message.
Actually, wait a sec, it looks like DS-2CD2355FWD-I is a 5MP camera, which you are trying to set to 3072x2048 (which is 6MP total), so that is likely to be the reason!
Even 3072x1728 should not really work as it slighlt in excess of your max resolution of the camera :)
I wonder if its somehow scaling down but Wave does display the stream info as being 3072x2048. Or maybe its just displaying what it thinks its set the resolution to. Anyway I'm glad you pointed this out and I'm dropping all my cameras to 2944x1656, which seems to be the max to stay under 5MP.
I can't see any loss in quality so I'm fine with that.
Thanks for your help.
