Could you please help me in calculating the Optical zoom limit distance for a ptz camera based on the focal length of the lens? Do you have any manual calculation or any website... I have attached the datasheet, can you help me out ? I don't want to consider the height of the object, or something else, Just based on the focal length and the specifications given , wanted to know the optical zoom limit distance...like upto 400m or upto 300m or upto 900m how much it can see if you calculate ? The focal length is 122.4 so how much distance it can see?

Hi What is Near focus limit in PTZ camera options , I can see this option in DVR , what is this?
