This camera is great value. It comes in a weatherproof plastic shell and is robust and easy to use. It is triggered by motion and takes clear color photos by day and by night, using a bright visible flash after dark. For this reason you don't want to use it in areas where strangers often pass by at night, as the flash may draw unwelcome attention to the camera. You can set its sensitivity, mode etc with a plug-in keypad. It runs on standard AA batteries and they last for months.
One thing that wasn't clear to me until I started using it was that, while you can set it to take a burst of 3 photos every time an animal passes (which gives you a better chance of catching the animal in the field of view), this only works in daylight. At night it takes a single flash however you set it, unless I'm missing something.
