Great article guys. I realize getting all of these was a tedious task but your efforts contributed to the best application summary I've seen. I'll be sharing this with our video project teams.

Great Article and very simple & helping for projects, even though that what i personally am experiencing with the clients is their perception on how they see the image & if its recognizable enough for them - for us the details could be very well enough and could establish a recognizable to a person for example & enough coverage - but for client what they see is a non-clear image thinking that they need to see a clear view (specially in low lux) , trying to make them understand that surveillance is not sometimes in having a 100% clear view but to establish the needed coverage and recognition they need... not sure if my perceptive is correct but this is what i have to deal with; hard minded clients!
