Better PTZ Functionality
New
I would like to see the PTZ functionality a little different. Advanced PTZ works pretty well for the most part, but is lacking in a few areas.
Enable / Disable PTZ mode: Is there a faster way to enable or disble PTZ mode? Maybe a keyboard shortcut like "P" or something. The problems comes when you have double clicked to enlarge the image and you are following them and you have to swithc cameras. You have to go up to the menu, click the ptz button then you have to double click to minimize the image to find the next camera you need, then do the whole process over again...
Scrolly mouse: In PTZ mode switch the scrolly mouse button from digital PTZ to PTZ zoom in and PTZ zoom out
With Axis Cameras, managing the positions usually erases saved positions, not very consistent.
Would like to be able to use the PTZ hotkeys while not in PTZ mode

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.

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.

Norman, we also believe it is more intuitive to use mouse scroll for optical zoom than digital zoom. All our engineers and lot of customers tell us the same. Please re-consider, or at least please offer an option to chooses whether mouse scroll will be used for optical zoom or digital zoom.

Hi.
I still think that PTZ controls in Nx Witness do not live up to the level of how user friendly Nx is in almost every other way.
Everything else is fast, resonsive and easy to use. Manual PTZ controls are just frustrating.
Every time I have to demonstrate this part to a possible client I feel my heart sink. -
Advanced PTZ is nice, but it can not replace the manual control.
I think it`s a good extended PTZ feature, but not a replacement.Its a lot of situations where its not feasible to add advanced PTZ, here are some examples:
- The client got 10 different PTZ cameras thats 3 years+ and no longer very popular models.
- Its not possible to give access to the camera to get advanced PTZ support added.
It`s also time consuming to keep up since advanced PTZ have to be enabled on a pr camera model basis.
So this is a possible pit-hole in project planning. And some times a big problem when you compete to take over a large system with a lot of different older PTZ models.Another point is that for the installers, its good that Advanced PTZ is only available on new models. Its an incentive for the customers to buy new cameras. But you can not force this on them when you try to make them change to Nx. It has to come later when they see the benefit.
So I really think that good manual control is the only universal and system wide solution.
And since you got manual control in Nx, both the desktop and mobile clients, it should live up to the standard of Nx.Right now the feeling I get from PTZ contol is: What the @%#! did they do here?
Instead of the usual Nx feeling: Wow, why did not everybody just do it like this in the first place! Its so fast and easy! -
Hi Fredrik,
Thank you for the feedback. It is definitely something our product team will have a look at.
Older cameras can be mapped as well as long as they support the absolute move in Onvif Device Manager.
Often newer models, other models share the same sensor size, the same focal length, and the same mechanics. If that is the case, often we can duplicate the mapping and the advanced PTZ can be done quite quickly.The biggest limitation we cannot overcome is network latency and therefore manual controls are always a bit challenging when you compare this to advanced PTZ.

The number one complaint I still get today (3 years later) is the PTZ functionality. A lot of my live operators hate using it because of the latency delays. It's too hard to follow someone. The shortcuts have helped.
The axis integration with presets is still questionable and I even have one PTZ that can only move side to side for some reason (with the advanced PTZ). My customer really liked the Exacq PTZ controls and remind me of that every time I see them on-site...

Thank you for the feedback Norman.
When it come to network latency, I actually think that its possible for some improvements in Nx.
It should be able to be just as responsive as ODM or other software based PTZ controls is over a ethernet connection.
But it will not be possible to get it to the level where analog cameras with RS232 controls was, I agree to that.
