I�m considering a security camera system for my home and hope you will help. I want cameras with enough �resolution?� so that I can recognize / identify someone at 30-40 ft. Most of the small system I�ve seen for home use are �useless� in that the resolution is so poor at a distance you can�t see faces just blurry figures. I doubt anyone with bad intentions will walk up and look in the camera at 3-4 ft. What type of outdoor cameras should I be considering.

Thank You,

If you want something that definitely works and is very high end, please take a look at our megapixel cameras:

These work with these stand alone NVRs:

or with this PC software:

You can watch some videos online about the NUUO software here:

There is a theory if you need to recognize somebody you know you should have at least 40 pixels/foot (vertical) and you need 60 pixels per foot in case if you want to identify somebody you don't know.

So if you have 1.3 Megapixel camera with 1/2" sensor format and 8 mm lens you are going to have 42 pixels/foot at 40 foot from camera and width of the field of view 31 ft.

If you need more (like 60 pixels/ft) you can put lens with higher lens focal length (12 mm, with 19.9ft) or put 3 Megapixel camera.

In case if you would have a 3Megapixel camera
