This has been my 2nd experience with a Vikari 4K trail camera. the Vikeri 4K is all I could ask for and performs as advertised….that is why I purchased a 2nd unit. The directions for set up are good so it only took a few minutes to get things rolling. The picture quality is very good and the “enlarge screen” option allows an up close view of game. The 120 degree field of view covers a lot of ground, and the .2 second shutter speed is fast enough to supply clear images on moving game. The sensitivity adjustment can filter out movement of smaller game and is a real plus for windy conditions. Add to these features a standard card that is inexpensive to replace if need be, and an eight battery power source that can power the unit for months. There are more expensive cameras on the market but after using my first Vikari 4K, I came to the conclusion that a 2nd purchase was a no brainer.
