I am using 2 of the Moultrie M100 which is a higher version of the M80. Moultrie cameras when set to video, take a picture first, then the video. The field of view in the video is narrower than in the picture. Moultrie said this is how it downloads. Night video is limited to 10 second. Extending this per Moultrie, it would be harder on batteries. A one year manufacture warranty and emailing them, I've had excellent customer service. I would not recommend cameras with audio unless set up over bait where a couple of bucks might fight or turkeys are gobbling. The microphone is highly suseptible to wind noise. If you notice the large microphones the media use are covered. This is to stop wind noise.
Over all I have been very satisfied with these cameras. On fast movement any camera will show some blur, but normal walking, these have been excellent.
Another camera I highly recommend is the Bushnell Trophy Trail Camera. I have 7 of these and they work flawlessly. Bushnell offers a two year warranty. Excellent customer service.
Both cameras are, small, easy to conceal, easy on batteries. If you are in bear county or possible theft area, I strongly recommend lock boxes. Moultrie offers the better built design box.
