nxWit Client (Win) - nxWit App (IOS)

Dear developers

First I will mention that I find nxWit a pretty good product.To make it better I want to suggest some features that might lead to easier working:

I was searching a surveillance software that is able to turn camera streams by 90 or 270 degrees during presentation. nxWit can do this. Some cams cannot rotate.

So I managed to arrange 3 cams (2 landscape and 1 portrait) in a good screen filling layout in WinClient.
During testing my orientation layouts it happend that I had thumb pictures over the timeline in portrait oriantation, that turned out to be much better to search special events. On the other hand now I have event thumbs on the right part of the screen in portrait orientation although it would be much better to have the event thumbs in landscape orientation.

FRQ 1.1: So I will formulate my first Feature Request (FRQ) - is it possible to allow IOS app to display the same layout as defined in nxWitClient in Windows)

On IOS app you can select the defined layout, but this will only filte to the defined cameras. I would rather define some iPhone (16:9) and different iPad (4:3) layouts for landscape and portrait orientation in nxWit Client on Windows, so that the layout could be switched automatically if I rotate the mobile device.

Btw: the aspect ratio of a non 16:9 stream (as happend to come from my Dahua cam's loRes stream) are not resized to correct aspect ratio on IOS devices

I would have some more FRQ, that all together are not urgent in any way but could be an input for further improvements. May I send them here or anywhere else ?

Michael

If screenshots are desired for further explanation, I will provide it soon.

    Hello Michael,

    Thank you for the feedback!

    I'm afraid I didn't get your idea 100% percent, so I will try to rephrase what I understood:

    1. Request to have in the mobile app layouts similar to layouts in the desktop client, where you can define cameras size, rotation and relative positions.
    2. Bug with aspect ratio for some cameras in the iOS app.

    Is it correct?

    If yes, about the #1 option – it's one of the most requested features for the mobile client, along with the bookmarks and analytics objects. I believe we'll implement it soon, but I currently cannot give you any estimates, when.

    About #2 – can you please send us screenshots and descriptions of how the camera is configured? In general it shouldn't depend on the camera model, but there may be some configuration options which aren't processed correctly.

    If you have more feature requests or any feedback suggestions – feel free to post them here. Even though we are not able to implement all of the requests we are getting, It's always useful to have some ideas to think about an be able to understand our users better. 

    Thanks again!

    Hi Alexandr

    thanks for your answer

    ad FRQ 1.1:

    third picture shows a 3 cam layout in a 4x4 grid. So you see again, thats no optimal layout in iOS app on an iPad (landscape 4:3 aspect). Nice to hear that iOS app will be changed soon :-)


    ad #2

    Let us name this issue as
    FRQ 1.2 - correction of Aspect ration of anamorph streams before recording the stream (for correct display on iOS and thumbnails)

    investigating the possibilities of my Dahua IPC-HDBW2231R-ZS i learnt, that lo-res streams historically during DVD era were recorded in special lo-res formats to save bandwidth and to achieve 2h of recording time on one DVD. These formats were neither 4:3 nor 16:9 aspect ratio, but were called anamorph.

    My Dahua only supports 3 non 16:9 (anamorph!) lo-res streams that have to be corrected after receiving the stream to be displayed or recorded in correct 16:9 format. Because the camera image sensor captures the same image area as for the hi-res 16:9 streams, but for the lo-res streams the data stream is sqeezed into historically normed D1, VGA or CIF formats. DVD player were capable to resize these streams. Sqeezing 16:9 sources to these old formats requires different anamorph recalculation to correct the aspect ratio.

    Dahua Menu

    In the upper picture you see the 3 possible Dahua lo-stream formats that transport the downscaled anamorph streams sqeezed into one of thee legacy but normed formats D1, VGA, CIF. Other cams of mine support 640x360 that would provide correct 16:9. 480x270 or 320x180 would be another possible lo-lo-res stream format with same aspect ratio, but both wouldn‘t be a historically known stream format. 
    To correct this for each stream, the correction cannot be a property of the whole cam definition, but has to be set by each stream of a defined camera. 

    Next screenshot explains two situations.
    First you see the wrong aspect ratio of the 16:9 captures but non 16:9 squeezed lo-res stream in 1st cam (only 1 lo-res stream) and in 3rd cam (2 defined streams hi-res and lo-res, currently lo-res stream is displayed.

    Secondly you see, that a 3 cam layout is displayed in the 4x4 grid on an iPad (landscape 4:3 aspect), what by no means is necessary. But you said it will be addressed in future releases.

    Last i will mention, that the correction should occur BEFORE saving the stream. During playback this wil avoid constantly, switching between two aspect ratios.
    nxWit Desktop does this correction during display, and doesnt show the same behaviour. Only thumbnail images are displayed in wrong aspect ratio. If saved after correction, thumbs will be displayed correct too.

    I will add another FRQ here because it is similar to 1.2: 
    FRQ 1.3 - manually change orientation of thumbnails:

    I would like to have two checkboxes (as grid or canvas property) to set thumbnails in timeline area (in the bottom line) to force always to portrait orientation and to set thumbnails in events preview thumbs (rightsided) always to landscape mode. During playback or search you can see 2-3 times more thumbs to find a special scene with moving objects. I personally would prefer these forced thumbs settings regardless to the actual orientation of the stream itself. But this may not be everyones favorite setting. So it should be done with checkboxes. 
    In the following screenshot you see it actually to be oriented the opposite way, what i would like to see.

    ... to be continued ... wait till answered ...
