100m lens will pull me in how far?

I need to capture a security gate 300' away. Am I wasting my time with a 100mm lens?

If its a 1/3" ccd will give a fov of 17', don't know if this helps.

Zooming from a distance has other factors like heat rise,rain and fog that will

block your image on some days and does not work well with IR.

 

Also unless the camera is up high headlights can cause grief -it will mask whats going on down at the gate at night. [camera dependent]

 

If you can get a local camera it is always going to beat a big lens -especially at night. [sending the gate cam via wireless is better]

 

Is it well illuminated ?

how much detail do you need ?
