IMO the best cam's on they market now, will be the Buckeye cam, and the reconyx brand camera's
they are by far less prone to issue's
I have been using remote triggered cam's since the early 90's with 35 mm film, I have bought 100+ cams over the yrs, far too many get stolen in my area< and based on my experience, ALL other brands are like pick of the litter, some times you get a great one some times you get one that works iffy at best.
things to consider when looking at trail cams will be things that matter to you
pic quality, personally 8 mp cam's take very nice pic's in day time, and ALL IR cam's are not so great at night, there are a few camera companys that still make color REAL flash camera's that take color pic's at night, I prefer them to be honest, due the much higher quality of the pic;s
but they also lead to more cams being stolen, as the flash can be seen from a LONG ways(500+ yards away ) and they suck battery power down a LOT faster, so less pic's on a set of battery's
which brings up battery life, the higher the MP of the cam, the more they IMO tend to drain power, some camera's offer solar panels to keep them running, and if in a remote place or not planning to cherck camera often, I highly suggest this set up, cold/temps, , amount of pic,. how many IR/s/flash power, all determine how long battery's last
a very important feature to me on cam's is a FAST wake up time and trigger time
this is where a lot of cheaper cams drop the ball, there SLOW to wake up,and or miss many many things, due to so slow a wake up, and then slow trigger speed if active, you end up with pic's of nothing, defeating the point of a remote trigger cam, as most want to see what triggered things?
but at same time, seem times cheaper cam's are worth there costs, if the odds of them growing legs is high, replacing 600+ dollar cams when one gets stolen grows old real fast and them 50-100 buck cams start to seem like better idea's, can run a few cams and get more details on things running your property!
but hands down , the reconyx and buckeye cam's are the top of the shelf in cam's
be glad to offer more info if you like, have q lot of experience with trail cams
