Selecting a camera is truly dependent upon your budget.  Personally we like Sony products...they are reliable and last a good long time when properly cared for.  
Of the Sony cameras on the market today here are a few of our selections.  Please note we do not promote Sony for monetary gain - it is merely because we believe in their product.

The prices vary greatly but it does give you plenty of options.

If your budget can afford I would also recommend a thermal imagery camera:
IR PROx Thermal Infrared Camera
IR-250 DX Thermal Imager
IR-235 DX Infrared Camera
IR-400 DX Series
IR-CAM 55x  (top of the line and best choice if you can afford it)

Hope this answers your questions!
