I bought these cameras for use in an area where there was a good chance they would get stolen so I didn't want to spend a ton of money on them. I also have two, much more expensive, name brand cams in a similar (slightly more secure) area so I have something to compare to. These cameras work just as well as the name brand cameras.

I have been using the same AA batteries for over a month now and they are still over 3/4 full. The daytime pictures come out crystal clear. The night vision pictures are a little blurry if the target is moving but... it is dark so... what do you expect.

One thing to note: Unless you want to get THOUSANDS of pictures of what must be triggered by the motion of cells dividing or pollen blowing in the air.... set the sensitivity to something less than max. I ended up with 14,000 (not exaggerating) pictures of absolutely NOTHING happening the first few days. Well... I didn't look through all 14,000 pictures so maybe SOMETHING happened but I got tired of looking after the first seven or so thousand pictures of a tree being a tree (not even blowing in the wind).

Overall I would buy again and recommend to anyone.
