Good luck. I am sure it will be worth what you pay for it.

It depends on how you wire them. a) RJ-45 = 100 Meters. RG-59 or RG-6 = up
to 800' to 1500' respectively (in some cases more) with a whole lot of
variables to contend with. b) Twisted sender = thousands of feet with a
whole lot of variables to contend with. c) Fiber = miles in some cases with
a whole lot of variables to contend with. d)Wireless 802.11 (a or b) WITH A
directional  antennae of the proper dB gain = more miles with a whole, whole
lot of variables to contend with. (Don't forget the cable itself must be out
of door/UV rated.)

There are no real out door cameras, it is the enclosure you put them in.

State the budget first then ask the model/brand. Outdoor Thermal Imaging
cameras can be had from 10K to 90K. That in you budget?
