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 can anyone tell me the difference between sector, preset and patrol in PTZ camera

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

Hi Can anyone tell me the difference between Colour/Mono camera and Day/Night camera?
