This is an excellent camera that offers a great balance of usable features, intuitive setup, and reasonable price.We have seen multiple large coyotes in our area and found out from Maryland wildlife experts that they are breeding with Canadian wolves; they're bigger and far bolder than coyotes I have seen in the past, and seem to be common despite the fact that we live in such a populated area (Washington DC metro). We have a small dog, so we wanted to see how close they're coming to our property. We ordered two cameras...one cheaper than this...and this one is by far the best, worth more than the price difference for ease of use and some of its features. We ended up taking this one to our house in Arizona to monitor mountain lion activity at our property there because it is easier to use and seems more reliable.It takes 8 AA batteries. We couldn't make it work with 4, though some say it does (there is probably a trick we couldn't figure out). No matter. I think we're going to pursue the solar charger since it is Arizona and why not use that? It has a great, user-friendly setup and menu screen. You can preview the images on the screen prior to removing the SD card (so if there's nothing you want to see you don't have to pull the card as we do on the other one). It has a pretty sensitive motion detector (keep it away from low branches or you'll have a bunch of nothing shots) and takes remarkably clear pictures and video (you can set it for photo, video, or both, as well as frame rate, length of video, resolution of video, number of pictures you want when triggered, sound or no, etc). It's very customizable depending on your needs (ie we really just want pics to see what is creeping around our fence). Battery life is ok; it's heavily dependent on settings, but we got about 30 days out of ours and a lot of it was nothing but squirrels (some deer, rabbits but no coyotes). Some of the videos are just black, for whatever reason, which is something I think other reviewers had an issue with. All of the images were viewable, but about 20% of the videos have been "unavailable". We're not sure if we actually missed something or if there is just a bug that creates these files (the file info is not showing a size on par with the other videos), but that's not great. Still, for what we need, and for the price compared to lower end models (which we have) and higher end models (my brother in law is a hunter with a $200+ version that is pretty amazing), we have no complaints about this one.FWIW, we have had a VERY mild winter this year with only a few sub 30°F nights since December, so I can't speak to performance in very cold weather (and now the camera is in Arizona). We are using a Samsung 32GB micro SD card and it's working great. Rain has not bothered it a bit.
