Using it for human surveillance. Too bad it's so exposed as it must Not be behind glass to trigger. IR sensors don't work thru glass. Physics always wins. These long-duration cams only turn on long enough to take the picture, unlike plug-in cams that use the continuous video to detect a trigger thru glass, that would kill the battery quickly. IR sensors of trail cams are passive until triggered and can run for months on AA alkalines. So, if you want to monitor from inside, you must use timed triggers. This nice cam is fully configurable for both. Outside, unlike animals, humans will simply destroy it or steal it if they see it. Paging thru thousands of photos on the cam is possible, but using your computer is much better as scanning software can quickly find the triggering offenders. Each picture is a fantastic high def thing. Over 81,000 16K photos fit on a 128GB card. 1080p HD video can store over 14 hours of HD video of your favorite 2 or 4 or more legged subjects. Cheap alkaline batteries took a 16K photo, every 5 seconds, 24/7 from 2PM Thursday to past noon on Saturday in rapid time mode. Walmart has 8 AA cells for $1.97. Works great.The no-glow leds are powerful past 100 ft but you need a 12VDC cord, not included curiously, to power them for long recordings. Animals will never know they are shining brightly at them as this light is invisible to them. Movies of maurading coons emptying my trashcans are undisturbed in total darkness. Not sure which animals can see IR light. Ask Google.Needs: secure theft-proof enclosure IR sensors can see and transmit IR lighting through holes in strong steel, lockable enclosure.12V power cord for long duration, intensive recording.Optional high power Lithium-ion battery pack and charger.Great unit at fantastic pricing until current president blocks importing Chinese goods.
