Cheaper cameras can: 1)be very hard on batteries, 2)poor quality pictures due to redness, streaks or blur. Some pictures are very grainy.
A couple of good brands are Moultrie and Bushnell. Moultrie offers a one year manufacture warranty and good customer service. If set to video, Moultrie cameras take a picture first, then the video. What one gets in the picture is often missed in the video due to a delay. Field of view in the video is narrower than in the picture. Moultrie said this is how it down loads. Night video is limited to 10 seconds. Lengthening this time would be harder on batteries as per Moultrie.
Bushnell offers a two year manufacture and good customer service. They have an option of longer night video. Also when set to video, this is what they take, no picture before it like the Moultries.
Look for a camera that the night video setting can be set for 10 second delay or less. The ability to use AA batteries is a plus in cold weather because one can use Lithium Ultimate which are a high voltage battery. These test 1.79 to 1.83 volt using a digital meter. This is like putting a higher cranking amp (larger) battery in a vehicle. The vehicle would turn over longer when starting in cold weather.
Lots of cameras on EBay, but a word of caution: if the seller is not authorized by the manufacture, there is no warranty.
Good luck in your choice.
