Model Question: CT Detection angle and Field of View


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.




You could send email to them and check the details maybe.

Hi Hana,



Trailcamerpro.com have the above details. They measure field of view with a ruler at a set distance and some maths. Detection angle is harder and one way is to do a slow walk test, a foot every 20 seconds, across the cameras view and work out where the camera first captures images and then map this back to the field of view.

Hope this helps,



Hi Hana, I know for Bushnell the manual has the FOV, it should be 50 degrees for yours. All the manuals are online so you just have to find your model. https://www.bushnell.com/bu-manuals.html 

As for the detection radius I agree with looking at trailcampro, to see if they've tested your model.


Fig 2 here; https://onlinelibrary.wiley.com/doi/full/10.1111/aje.12573 might help for the Bushnell. I haven't tested Stealthcams.
