Question: I've read that you can view from the sd card and erase the card, but are the pictures uploaded to the unit?  and if so, how much will it hold?
Document: I bought this to view pictures only (no video) from my Bushnell Trophy cam's. At best, it works SOME of the time, but it's terribly slow to read the SD card, and I had to struggle to get the keys to work. Very aggravating. I had to push the buttons very hard to get the viewer to navigate.
The viewer did tell me that the sd card was locked a few times. Before I put the sd cards in I pushed the switch a few time from lock to unlock. this seemed to fix the problem.. After a while, a few times doing this seemed to fix the problem because I haven't had the sd card locked come up at all. This viewer works very well. Also when you erase all photos it would erase a few and then go back to the menue screen.
I recently used this product on an elk hunt, its a little big but thats to be expected with a large screen. I was pleased with the unit overall as it wasn't too heavy to have in my hunt pack, the batteries lasted fine for my hunt and the ability to zoom and pan the picture was great for those images on the edge.The only con I found is the rubber flap to cover the sd card slot.
By the way, you can also use micro-sd cards with the SD adapter. There is no speaker but there is a headphone jack and the sound is good. Battery life may be an issue even with AA alkalines. The alternative is to use Lithium batteries but those are $2 each as opposed to 25 cents or so for the alkalines. I plan to carry spares but with heavy usage I would use the lithiums.One last thing, the unit plays videos, still pictures and sound files.
that you want to an internal card that you install and erase all the other pics that you don't want to keep on your current card, that is a great feature so that you don't have all those unwanted pics on your card.
This makes looking at the game camera pictures so much easier than putting the chip in the lap top and downloading them. you can delete the ones you don't want to save and keep the good ones.
This viewer is a replacement for one with a smaller screen. This viewer is easier to work, easier to save pictures and a much bigger screen that works very well in any lighting conditions out in the woods. It's a great addition.
Had to send this item back. It should be stated on description that this only views chips taken with their camera. Was not able to read pictures taken from my Bushnell camera.
This thing works fine, but it's a waste of money if you already own an iPhone or iPad. All you need is a MiniUSB cable and Apple's Lightning to USB adapter. Then the Photo app on the iOS device lets you download and view the still photos and the movies on the Moultrie device. You can get the cable and adapter for around $30 or so, and the iPad screen is much bigger and better than this Video Viewer's.
I have thee older card reader. It reads all my cameras fine. The new upgrade Is designed to only read Moultrie cameras.Beware!! !
