I am familiar with Axis' Digital Auto-tracking from a fixed Lens sensor on specific mega-pixel camera lines "P" for example.
I guess the term Mechanical Auto-tracking applies to a similar function using a PTZ camera. I'm interested in this solution, where the PTZ is config'd to a default or 'home' view (the gate entrance for this example) where I want the camera to zoom-in and follow the object as it approaches the camera and continue to follow the object zooming as necessary when the object turns right and eventually disappears about 350' away, at which time the camera returns to the 'home' view
This is an add-on to a Milestone platform.
Your recommendations are appreciated. Note: Functionality, durability, ease of deployment are favored over cost.
Thank you in advance
