> Anybody recommend a good and free CCTV lens calculator?

I don't do many "cheap" installations so I basically just keep two lenses on
hand.  They cover 99% of my applications.  I keep a 2.8-12mm Varifocal AI
and a 5.5-33mm Varifocal AI lens on the shelf.  The 2.8-12mm covers probably
95% of all applications and its pretty darned inexpensive if you shop
around.  The savings to go with a fixed focal lens is more than outweighed
by the labor savings when the customer asks me to adjust the field of view.
I just hand the customer one of my GMRS radios and tell them to stand in
front of the monitor while I go get on the lift, climb the pole, setup the
ladder, or whatever.  I tap in a t-connector at the camera (if signal
strength is not an issue and I use my inspection monitor so I can see what
they see.  One trip up the ladder.  One lens on the camera.  When the
customer says ok then its OK.  If they want it changed in the future then
its a billable service call because they said it was ok the way it was
before.

It also helps them to understand things like, "No.  Wider is not better.
More cameras is better."

For field calculations prior to bidding a job I have an eyeball monitor and
a 12VDC camera that I run off a battery pack.  This often helps me show
customers what they will get before hand, and the preparedness often lands
the client.  There are a few cheap skates out there who will try to use that
info to do it themselves.  Let them.  Once they have demonstrated what they
are I am always too busy to help them when they call back. "Gee, we are
awfully busy right now.  If you really want us to look at it I have a whole
in my schedule in about 5 weeks.  If you want us out you need to schedule
for that time now.  There will be a charge for coming out of course."  If
they hem and haw, when they call back I seem to have always scheduled that
time, but if they can put it off another week I might be able to work them
in.

Its all about maximizing your time.
