I have three different models of trail cameras for security purposes. Had four but someone walked off with one of them. They all have their limitations. Had two viewing same thing for several months and they did not always capture the same movements. One goes nuts when it gets cold and fills a 4 gig card in one night. 3950 pictures of nothing. Did it last year and same this year. Haven't had any of them fail completely, just not doing what they should do sometimes.
If you read the comments owners make of several different brands and models you will see many complaints about all of them.
