CT Detection angle and Field of View

Hello,

I'm currently working on estimating the density of bezoar goats in Iraqi Kurdistan using REM. My data consists of camera trap images over a seven-year period. The problem is when I deployed my cameras as an amateur, I didn't detect the field of view and detection angle of my camera traps. I used Bushnell trophy cam and stealth cam STC-P12 (pictures attached) with a sample picture from each of my cameras.

I am currently looking for information on the detection angle and field of view for these two cameras. I have searched online but I haven't been able to find it. Your help and advice will be very much appreciated.

Thanks,

Hana
