It does work to a certain level. Very difficult to determine NETD sensitivity in mK which is not overtly specified for NF-583s. From what I can determine, it is probably no better than 50mK. The low resolution does not help it either for further distant objects. It does have uses for helping determine energy waste around windows, doors, etc, and looking for hotspots on PCB boards for circuit repair. Software is not intuitive and difficult to configure requiring reverting to defaults a lot.

Not sure if it's the app or the camera or both. The NF583S gets good reviews so I'm going to say it's the app..lol. The app is glitchy, tends to freeze, not often; enough to annoy, it turns grainy when aimed up and not up to the sky, just a slight bit.. maybe 5-10 degrees, and once in a while the settings don't change when selected (only for the 4 selectable presets not the verticle low/high limit adjustments, they're fine) Video is good, pictures are good, temperature guages are good, etc..

Used daily for most anything. App could be better, still remarkable considering price of NF-583S & abilities. Must play w/ adjustments to figure out for self. Some color pallets work for certain tasks/materials over others. Experience w/ IR, thermal, radar, etc gives better insight. Hold still for more detailed image. -neighborhood details thru brick wall of house -ppl behind priv. fence -unseen aircraft in sky -video heart beating in chest -locate tumor in pet -pinpoint cold draft Very useful.
