I have only set it up in our demo version, so I haven’t had a customer use it yet, but what I found to not like about it was you have to configure the cameras placement on a map view, there is no way to scale the positioning of where it falls on the image. What would be great is, rather than setting up the nearby cameras from a map view you do by placing the camera on the image, that way the icon falls exactly where you want it.
For instance I would like to see the ability to drag the camera onto the image say, on top of the sheds you see in your posted scene. Rather than have to create a view with enough tiles to see nearby cameras.
This way if I see someone walks into a shed, I just click right on the icon and be taken to that camera inside the shed. A motion indicator would be icing on the cake.
One would think that creating a false map, of incorrectly placed cameras on the map orienting the cameras correctly on the image would fix this, but Milestone is doing something more behind the scenes to have the icon on the image show up, as image placement of the icons change as more cameras are added to the navigator further limiting the ability to trick it.
