Hi Everyone,

 

Our Client would like to get a head/shoulders shot of people as they enter through the main entrance door of the building.

 

Current camera position is 7m away from the door.

 

My calculations suggest that I would need a 45-60mm lens.

 

Mostly that would mean a box camera with lens attached but he thinks it's ugly looking so does anyone know of a dome camera with a long lens on it as I've never come across them before.

 

Thanks!

 

ps. needs to be wide dynamic too (just to make things even more challenging)

 

 

 

id suggest your calcs are off first of all.

same here unless you want to see their retina.

Yes - apologies James, you are right.

 

at 7m with an field of view of 1m, I need a 35mm lens (assuming 1/3in)

 

Is that better?

hmm..retina would be good too!

yeah id say 33mm for 1m width but that's very narrow.

not really. DDA width of doors should be 900mm

 

don't want it too much wider or won't get head/shoulders.

 

ps. i hope the arm is healing nicely

Yes - apologies James, you are right.

LOL,

 

still think 35mm is to much.

question still stands though - has anyone come across a dome camera with 35mm lens?

not that i kmow of unless ptz.

something covert with your choice of lens might be the way to go, have a look at systemq.
