Better PTZ Functionality

    I will address the enabling of the PTZ with our UI team. 

    Regarding the zoom in and delay, in general, this is resolved with our Advanced PTZ functionality which allows you to draw a rectangle around a target and the camera zooms in on it. Also, this supports point-and-click which eliminates that downside of the delay in the controls. 

    More information can be seen in the following video:

    Shortcuts for PTZ control would be great. "P" for example would be great to enable/disabled PTZ function on a selected camera.

    Same for zoom in and out. Maybe the plus and minus signs?

    Same also for taking a screenshot. Maybe F9 or something to keep it in the same part of the keyboard.

    I would also like to see the deley issues fixed. Its cery hard to control PTZ cameras in NX because of this.

    I can control the same camera from ODM (Onvif device manager) and NX from the same computer, and ODM is way more respnsive.

    Hello Fredrik and Edward,

     

    I would also like to see the shortcuts for activating the PTZ and an option to enable the mouse scroll to controlo the Zoom when in PTZ mode.

     

    However, the delay that Fredrik reported (long ago) can actually be solved by just reducing the Buffer in:

       Main Menu-> "Local Settings" -> "Advanced" tab and decrease "Maximum Live Buffer Length" from 600 ms to lower values.

     

    I know it might be no longer relevant to your previous case, but if other people wonder about it, I would like to include the tip in this post.

    I have already been using the the PTZ cameras with reduced buffer length for quite a while, and it helps a bit in the desktop client. So this is something I can recommend.
    But when controlling PTZ cameras from the mobile app its not possible to adjust the buffer length to make it more responsive.

    Advanced PTZ is nice when you want to zoom in on somehing that is within the view. But when you need to look around and turn the PTZ in big open areas it can not replace the normal PTZ controls. And Advanced PTZ is not available in the app.

    I`m very happy that you are looking at ways to improve the PTZ capabilities now as this will make NX even more awesome.

    Hi Fredrik,

    To turn around quickly, the PTZ presets might circumvent the issue you encounter. 

    Just set up 4 presets, one for north, south, west, and east. Not ideal, but I might solve the issue for now.

    @Edward Dickey,

    Please have a look at our Nx Witness 4.0 Beta we recently published. In v4.0 you can enable/disable PTZ with the letter 'P' as you requested.

    Dear Norman,

     

    That is good news! Thank you for the update.

     

    What about the Scrolling zoom? Using the mouse scroll to to PTZ Zoom when in PTZ Mode

     

    Is this something that is coming also?

    Hi Miguel,

    The mouse scroll is reserved for digital zooming on any camera or even the whole layout. 

    The best thing is to use the zoom function for the advanced PTZ feature when you want to zoom in or zoom out.
