It is equipped with 120° detecting range which is blazingly fast and makes sure that you don’t miss a single bit of the action whether it is fast moving or slow moving. 

It is recommended to be around three meters. The rotation angle of this model is horizontal 355/vertical 120. If it is too high, the shooting distance will be reduced. 

As long as you insert the filters upright into the filter holder and they are not thicker than 2 mm, they will fit.

Yes, I believe you can with any trail cam. There are several videos on YouTube. You need a 4.0x1.7mm plug. I saw one video that explains a direct hard wire. After watching some videos, I decided it was easier and about the same price to buy the Stealth Cam 12v external battery pack with solar panel. I paid $50 at Academy Sports online. Plus the 4.0x1.7mm plug from Amazon. But if you like to make things, there are plenty of videos on making your own solar battery packs.
